一、环境准备

1、架构

创建3台虚拟机，分别作为controll节点、network节点和compute1节点。

Controller节点：1processor，2G memory,5G storage。

Network节点：1processor，2G memory,5G storage。

Comute1节点：1processor，2G memory,5G storage。

架构图：

外部网络：提供上网业务，外界登录openstack（在上图为蓝色模块）

管理网络：三节点通信比如keystone，认证，rabbitmq消息队列。（在上图为红色模块）

业务网络：网络节点和计算节点中虚拟机数据通信，比如dhcp，L2，L3。（在上图为绿色模块）

2、三个节点网卡配置

Controller节点：一张网卡，配置eth0为管理网络

# This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The loopback network interfaceauto loiface lo inet loopbackauto eth0iface eth0 inet staticaddress 10.1.101.11netmask 255.255.255.0gateway 10.1.101.254dns-nameservers 10.1.101.51

配置/etc/hosts如下：

root@ubuntu:~# cat /etc/hosts127.0.0.1       localhost#127.0.1.1      ubuntu#controller10.1.101.11    controller#network10.1.101.21    network#compute110.1.101.31    compute1# The following lines are desirable for IPv6 capable hosts::1     ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters

Network节点：三张网卡，配置eth0为管理网络，eth1为业务网络，eth2为外部网络，需特殊配置。

root@ubuntu:~# cat /etc/network/interfaces # This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The loopback network interfaceauto loiface lo inet loopbackauto eth0iface eth0 inet staticaddress 10.1.101.21netmask 255.255.255.0gateway 10.1.101.254dns-nameservers 10.1.101.51auto eth1iface eth1 inet staticaddress 10.0.1.21netmask 255.255.255.0# The external network interfaceauto eth2iface eth2 inet manualup ip link set dev $IFACE updown ip link set dev $IFACE down

配置/etc/hosts如下：

root@ubuntu:~# cat /etc/hosts127.0.0.1       localhost#127.0.1.1      ubuntu#network10.1.101.21    network#controller10.1.101.11    controller#compute110.1.101.31    compute1# The following lines are desirable for IPv6 capable hosts::1     ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters

Comput节点：两张网卡，配置eth0为管理网络，配置eth1为业务网络。

root@ubuntu:~# cat /etc/network/interfaces # This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The loopback network interfaceauto loiface lo inet loopbackauto eth0iface eth0 inet staticaddress 10.1.101.31netmask 255.255.255.0gateway 10.1.101.254#dns-nameservers 192.168.1.3dns-nameservers 10.1.101.51auto eth1iface eth1 inet staticaddress 10.0.1.31netmask 255.255.255.0

配置/etc/hosts如下：

root@ubuntu:~# cat /etc/hosts127.0.0.1       localhost#127.0.1.1      ubuntu#compute110.1.101.31    compute1#controller10.1.101.11    controller#network10.1.101.21    network# The following lines are desirable for IPv6 capable hosts::1     ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters

3、确认网络已经配置好

Controller节点：

# ping -c 4 openstack.org【ping通外网】

# ping -c 4 network【ping通网络节点的管理网络】

# ping -c 4 compute1【ping通计算节点的管理网络】

Network节点：

# ping -c 4 openstack.org【ping通外网】

# ping -c 4 controller【ping 通控制节点的管理网络】

# ping -c 4 10.0.1.31【ping 通计算节点的tunnel网络】

Compute节点：

# ping -c 4 openstack.org【ping外网通】

# ping -c 4 controller【ping 控制节点的管理网络通】

# ping -c 4 10.0.1.21【ping 通网络节点的tunnel网络】

二、基础环境配置

1、设置全局环境变量

为了方便配置后续配置，先设置全局的环境变量。

controller节点设置：

cat > /root/novarc << EOFexport OS_USERNAME=adminexport OS_PASSWORD=passwordexport OS_TENANT_NAME=adminexport OS_AUTH_URL=http://controller:35357/v2.0export SERVICE_ENDPOINT="http://controller:35357/v2.0"export SERVICE_TOKEN=servicetokenexport MYSQL_PASS=passwordexport SERVICE_PASSWORD=passwordexport RABBIT_PASSWORD=passwordexport MASTER="10.1.101.11"EOFcat /root/novarc >> /etc/profilesource /etc/profile

compute节点设置：

# Create the environment variablescat > /root/novarc << EOFexport OS_TENANT_NAME=adminexport OS_USERNAME=adminexport OS_PASSWORD=passwordexport MYSQL_PASS=passwordexport SERVICE_PASSWORD=passwordexport RABBIT_PASSWORD=passwordexport SERVICE_TOKEN=stackinsiderexport CONTROLLER_IP=controllerexport MASTER=computeexport LOCAL_IP="$(/sbin/ifconfig eth1 \       | awk '/inet addr/ {print $2}' | cut -f2 -d ":")"EOF # Update the global environment variables.cat /root/novarc >> /etc/profilesource /etc/profile

2、更新系统

在三个节点都要执行下面操作。

第一步、安装Ubuntu Cloud Archive

# apt-get install python-software-properties# add-apt-repository cloud-archive:icehouse

Ubuntu Cloud Archive是一个特殊的库允许你安装Ubuntu支持的稳定的最新发布的OpenStack。

第二步、更新系统

# apt-get update# apt-get dist-upgrade 【//lxy:需要十分钟，耐心等待】

第三步，安装Ubuntu 13.10 backported kernel

Ubuntu12.04需要安装这个Linux kernel来提升系统的稳定性。

# apt-get install linux-image-generic-lts-saucy

第四步，重启系统生效

# reboot

3、安装NTP（Network Time Protocal）

为做到每个节点的时间同步，需要在每个节点都安装ntp，然后修改配置，将/etc/ntp.conf添加controller为时间源。

在controller节点：

第一步、安装

# apt-get install ntp

第二步、配置/etc/ntp.conf

# Use Ubuntu's ntp server as a fallback.server ntp.ubuntu.com server 127.127.1.0fudge 127.127.1.0 stratum 10

将ntp.ubuntu.com作为时间源，此外添加一个本地时间源，以防网络时间服务中断，其中server 127.127.1.0表示本机是ntp服务器。

或者执行下面命令：

sed -i 's/server ntp.ubuntu.com/ \server ntp.ubuntu.com \server 127.127.1.0 \fudge 127.127.1.0 stratum 10/g' /etc/ntp.conf

第三步，重启ntp服务。

#service ntp restart

在controller之外的节点，

第一步，安装

# apt-get install ntp

第二步，配置/etc/ntp.conf，将controller作为时间源。

# Use Ubuntu's ntp server as a fallback.server controller

或者执行命令：

sed -i -e " s/server ntp.ubuntu.com/server controller/g" /etc/ntp.conf

第三步：重启NTP服务。

4、安装数据库

每个节点都要安装python-mysqldb组件，用于数据库连接，只有主控需要安装mysqlserver。

controller节点：

第一步安装：

# apt-get install python-mysqldb mysql-server

Note:安装过程终端会提醒输入mysql root账户的密码，这里设置为password。

第二步，配置/etc/mysql/my.conf文件

将[mysqld]模块中bind-address设置为controller节点管理网络的ip，确保其他节点通过管理网络获取Mysql服务。也可以设置为0.0.0.0，就是将mysql服务绑定到所有网卡。

[mysqld]...bind-address = 10.1.101.11

在[mysqld]模块bind-address后面增加如下配置，来设置UTF-8字符集和InnoDB。

[mysqld]...default-storage-engine = innodbcollation-server = utf8_general_ciinit-connect = 'SET NAMES utf8'character-set-server = utf8

第三步，重启mysql服务使设置生效

# service mysql restart

第四步，删除匿名用户

数据库第一次启动时会创建一些匿名用户，必须将这些用户删除，否则后面数据库连接会出错。

# mysql_secure_installation

Note:

1、该命令提供一堆选择给你来改善mysql数据库的安全性，除了不要改密码，其他都选yes，除非有你自己的理由。

2、如果mysql_secure_installation命令失败则执行

# mysql_install_db

# mysql_secure_installation

第五步，创建OpenStack中的Database,Users,Privileges

mysql -uroot -p$MYSQL_PASS << EOFCREATE DATABASE nova;GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'controller' IDENTIFIED BY '$MYSQL_PASS';CREATE DATABASE glance;GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'controller' IDENTIFIED BY '$MYSQL_PASS';CREATE DATABASE keystone;GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'controller' IDENTIFIED BY '$MYSQL_PASS';CREATE DATABASE cinder;GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'controller' IDENTIFIED BY '$MYSQL_PASS';CREATE DATABASE neutron;GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY '$MYSQL_PASS';GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'controller' IDENTIFIED BY '$MYSQL_PASS';FLUSH PRIVILEGES;EOF

在controller之外的节点安装python-mysqldb

# apt-get install python-mysqldb

5、安装消息代理RabbitMQ

第一步，安装

# apt-get -y install rabbitmq-server

第二步，改密码

RabbitMQ默认创建一个用户，用户名密码都是guest，执行以下命令将guest用户的密码改为password

#rabbitmqctl change_password guest $RABBIT_PASSWORD

在用到RabbitMQ的openstack服务配置文件中都要修改rabbit_password。

三、安装OpenStack服务

1、安装keystone

在controller节点安装OpenStack认证服务.

第一步、安装keystone

# apt-get install keystone

第二步、配置/etc/keystone/keystone.conf

sed -i -e " s/#admin_token=ADMIN/admin_token=$SERVICE_TOKEN/g; \s/#public_bind_host=0.0.0.0/public_bind_host=0.0.0.0/g; \s/#admin_bind_host=0.0.0.0/admin_bind_host=0.0.0.0/g; \s/#public_port=5000/public_port=5000/g; \s/#admin_port=35357/admin_port=35357/g; \s/#compute_port=8774/compute_port=8774/g; \s/#verbose=false/verbose=True/g; \s/#idle_timeout=3600/idle_timeout=3600/g" /etc/keystone/keystone.conf

更新keystone.conf中MySQL连接

默认使用的是connection = sqlite:var/lib/keystone/keystone.db，而不是mysql。

[database]# The SQLAlchemy connection string used to connect to the databaseconnection = mysql://keystone:KEYSTONE_DBPASS@controller/keystone

或者执行命令

sed -i '/connection = .*/{s|sqlite:///.*|mysql://'"keystone"':'"$MYSQL_PASS"'@'"$MASTER"'/keystone|g}'\      /etc/keystone/keystone.conf

第三步、删除keystone.db

默认情况，Ubuntu包创建了一个SQLite数据库。删除/var/lib/keystone/目录下的keystone.db文件确保后面不会出错。

# rm /var/lib/keystone/keystone.db

第四步、重启keystone并同步数据库

# service keystone restart# keystone-manage db_sync

第五步、创建OpenStack中的users, tenants, services

首先创建Keystone数据导入脚本Ksdata.sh ，内容如下：

vi Ksdata.sh #!/bin/sh## Keystone Datas## Description: Fill Keystone with datas.# Mainly inspired by http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin# Written by Martin Gerhard Loschwitz / Hastexo# Modified by Emilien Macchi / StackOps## Support: openstack@lists.launchpad.net# License: Apache Software License (ASL) 2.0##ADMIN_PASSWORD=${ADMIN_PASSWORD:-password}ADMIN_PASSWORD=${ADMIN_PASSWORD:-$OS_PASSWORD}#SERVICE_PASSWORD=${SERVICE_PASSWORD:-$ADMIN_PASSWORD}#export SERVICE_TOKEN="password"export SERVICE_ENDPOINT="http://localhost:35357/v2.0"SERVICE_TENANT_NAME=${SERVICE_TENANT_NAME:-service}get_id () {    echo `$@ | awk '/ id / { print $4 }'`}# TenantsADMIN_TENANT=$(get_id keystone tenant-create --name=admin)SERVICE_TENANT=$(get_id keystone tenant-create --name=$SERVICE_TENANT_NAME)DEMO_TENANT=$(get_id keystone tenant-create --name=demo)INVIS_TENANT=$(get_id keystone tenant-create --name=invisible_to_admin)# UsersADMIN_USER=$(get_id keystone user-create --name=admin --pass="$ADMIN_PASSWORD" --email=admin@domain.com)DEMO_USER=$(get_id keystone user-create --name=demo --pass="$ADMIN_PASSWORD" --email=demo@domain.com)# RolesADMIN_ROLE=$(get_id keystone role-create --name=admin)KEYSTONEADMIN_ROLE=$(get_id keystone role-create --name=KeystoneAdmin)KEYSTONESERVICE_ROLE=$(get_id keystone role-create --name=KeystoneServiceAdmin)# Add Roles to Users in Tenantskeystone user-role-add --user-id $ADMIN_USER --role-id $ADMIN_ROLE --tenant-id $ADMIN_TENANTkeystone user-role-add --user-id $ADMIN_USER --role-id $ADMIN_ROLE --tenant-id $DEMO_TENANTkeystone user-role-add --user-id $ADMIN_USER --role-id $KEYSTONEADMIN_ROLE --tenant-id $ADMIN_TENANTkeystone user-role-add --user-id $ADMIN_USER --role-id $KEYSTONESERVICE_ROLE --tenant-id $ADMIN_TENANT# The Member role is used by Horizon and SwiftMEMBER_ROLE=$(get_id keystone role-create --name=Member)keystone user-role-add --user-id $DEMO_USER --role-id $MEMBER_ROLE --tenant-id $DEMO_TENANTkeystone user-role-add --user-id $DEMO_USER --role-id $MEMBER_ROLE --tenant-id $INVIS_TENANT# Configure service users/rolesNOVA_USER=$(get_id keystone user-create --name=nova --pass="$SERVICE_PASSWORD" --tenant-id $SERVICE_TENANT --email=nova@domain.com)keystone user-role-add --tenant-id $SERVICE_TENANT --user-id $NOVA_USER --role-id $ADMIN_ROLEGLANCE_USER=$(get_id keystone user-create --name=glance --pass="$SERVICE_PASSWORD" --tenant-id $SERVICE_TENANT --email=glance@domain.com)keystone user-role-add --tenant-id $SERVICE_TENANT --user-id $GLANCE_USER --role-id $ADMIN_ROLESWIFT_USER=$(get_id keystone user-create --name=swift --pass="$SERVICE_PASSWORD" --tenant-id $SERVICE_TENANT --email=swift@domain.com)keystone user-role-add --tenant-id $SERVICE_TENANT --user-id $SWIFT_USER --role-id $ADMIN_ROLERESELLER_ROLE=$(get_id keystone role-create --name=ResellerAdmin)keystone user-role-add --tenant-id $SERVICE_TENANT --user-id $NOVA_USER --role-id $RESELLER_ROLENEUTRON_USER=$(get_id keystone user-create --name=neutron --pass="$SERVICE_PASSWORD" --tenant-id $SERVICE_TENANT --email=neutron@domain.com)keystone user-role-add --tenant-id $SERVICE_TENANT --user-id $NEUTRON_USER --role-id $ADMIN_ROLECINDER_USER=$(get_id keystone user-create --name=cinder --pass="$SERVICE_PASSWORD" --tenant-id $SERVICE_TENANT --email=cinder@domain.com)keystone user-role-add --tenant-id $SERVICE_TENANT --user-id $CINDER_USER --role-id $ADMIN_ROLE

运行脚本

#bash Ksdata.sh

第六步，创建endpoints

首先创建脚本Ksendpoints.sh

#vi Ksendpoints.sh #!/bin/sh## Keystone Endpoints## Description: Create Services Endpoints# Mainly inspired by http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin# Written by Martin Gerhard Loschwitz / Hastexo# Modified by Emilien Macchi / StackOps## Support: openstack@lists.launchpad.net# License: Apache Software License (ASL) 2.0## MySQL definitionsMYSQL_USER=keystoneMYSQL_DATABASE=keystoneMYSQL_HOST=$MASTERMYSQL_PASSWORD=$MYSQL_PASS# Keystone definitionsKEYSTONE_REGION=RegionOne#SERVICE_TOKEN=passwordSERVICE_ENDPOINT="http://localhost:35357/v2.0"# other definitions#MASTER="192.168.0.1"while getopts "u:D:p:m:K:R:E:S:T:vh" opt; do  case $opt in    u)      MYSQL_USER=$OPTARG      ;;    D)      MYSQL_DATABASE=$OPTARG      ;;    p)      MYSQL_PASSWORD=$OPTARG      ;;    m)      MYSQL_HOST=$OPTARG      ;;    K)      MASTER=$OPTARG      ;;    R)      KEYSTONE_REGION=$OPTARG      ;;    E)      export SERVICE_ENDPOINT=$OPTARG      ;;    S)      SWIFT_MASTER=$OPTARG      ;;    T)      export SERVICE_TOKEN=$OPTARG      ;;    v)      set -x      ;;    h)      cat <

运行脚本

# bash Ksendpoints.sh

第七步，验证

现在keystone已经安装完成，验证身份认证服务安装是否正确。

# keystone user-list# keystone user-role-list --user admin --tenant admin

2、安装OpenStack客户端

安装完后，可以通过命令来调用OpenStack各个服务的api。

# apt-get install python-pip# pip install python-keystoneclient# pip install python-cinderclient# pip install python-novaclient# pip install python-glanceclient# pip install python-neutronclient# 也可以用到时再安装# pip install python-swiftclient# pip install python-heatclient# pip install python-ceilometerclient# pip install python-troveclient

3、安装Glance(镜像服务)

在controller节点安装image服务

第一步、安装glance。

# apt-get install glance

第二步、配置

因为glance包含两类服务所以修改配置文件/etc/glance/glance-api.conf和/etc/glance/glance-registry.conf

更新glance的认证配置。

默认:

[keystone_authtoken]

auth_host = 127.0.0.1

auth_port = 35357

auth_protocol = http

admin_tenant_name = %SERVICE_TENANT_NAME%

admin_user = %SERVICE_USER%

admin_password = %SERVICE_PASSWORD%

修改为：

[keystone_authtoken]

auth_host = 127.0.0.1

auth_port = 35357

auth_protocol = http

admin_tenant_name = service

admin_user = glance

admin_password = password

或者用下面命令：

sed -i -e " s/%SERVICE_TENANT_NAME%/service/g; \s/%SERVICE_USER%/glance/g; s/%SERVICE_PASSWORD%/$SERVICE_PASSWORD/g; \" /etc/glance/glance-api.conf  /etc/glance/glance-registry.conf

修改两个文件中[database]模块数据库连接，

默认为：

#connection = <None>修改为：

connection = mysql://glance:password@controller/glance

或直接执行命令

sed -i '/#connection = 
      
       /i\connection = mysql://'glance':'"$MYSQL_PASS"'@'"$MASTER"'/glance' \/etc/glance/glance-registry.conf /etc/glance/glance-api.conf
      

在[DEFAULT]中增加以下配置

[DEFAULT]rpc_backend = rabbitrabbit_host = controllerrabbit_password = RABBIT_PASS

设置flavor为keystone

sed -i 's/#flavor=/flavor=keystone/g' /etc/glance/glance-api.conf /etc/glance/glance-registry.conf

第三步、删除glance.sqlite

# rm /var/lib/glance/glance.sqlite

第四步、检查配置

[keystone_authtoken]#auth_host = 127.0.0.1auth_uri = http://controller:5000auth_host = controllerauth_port = 35357auth_protocol = httpadmin_tenant_name = serviceadmin_user = glanceadmin_password = password

第五步、重启glance相关服务并同步数据库

#service glance-api restart#service glance-registry restart#glance-manage db_sync

第六步、下载镜像测试glance服务

#wget https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img#wget http://cloud-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64-disk1.img

添加cirros镜像

#glance add name=cirros-0.3.2-x86_64 is_public=true container_format=bare \       disk_format=qcow2 < cirros-0.3.2-x86_64-disk.img

查看镜像

#glance index

4、安装cinder(块存储)

块存储，cinder用作虚拟机存储管理，管理卷，卷快照，卷类型。包括cinder-ap、cinder-volume、 cinder-scheduler daemon、 Messaging queue。在controller节点安装cider。

第一步、安装cinder组件

# apt-get install -y cinder-api cinder-scheduler cinder-volume iscsitarget \    open-iscsi iscsitarget-dkms python-cinderclient linux-headers-`uname -r`

第二步，修改iscsitarget配置文件并重启服务

# sed -i 's/false/true/g' /etc/default/iscsitarget# service iscsitarget start# service open-iscsi start

第三步，配置cinder文件

默认为：

[DEFAULT]

rootwrap_config = /etc/cinder/rootwrap.conf

api_paste_confg = /etc/cinder/api-paste.ini

iscsi_helper = tgtadm

volume_name_template = volume-%s

volume_group = cinder-volumes

verbose = True

auth_strategy = keystone

state_path = /var/lib/cinder

lock_path = /var/lock/cinder

volumes_dir = /var/lib/cinder/volumes

配置为：

# cat >/etc/cinder/cinder.conf <

第四步、同步cinder数据库，并重启相关服务

# cinder-manage db sync# service cinder-api restart# service cinder-scheduler restart# service cinder-volume restart

5、安装nova(计算服务)

controller节点：

第一步、安装nova组件

# apt-get install nova-api nova-cert nova-conductor nova-consoleauth \nova-novncproxy nova-scheduler python-novaclient

第二步、修改配置/etc/nova/nova.conf

cat >/etc/nova/nova.conf <

第三步、删除nova.sqlite数据库

# rm /var/lib/nova/nova.sqlite

第四步、同步数据库、重启服务

# nova-manage db sync# service nova-conductor restart# service nova-api restart# service nova-cert restart# service nova-consoleauth restart# service nova-scheduler restart# service nova-novncproxy restart

第五步、检查nova服务是否安装成功（确保nova-cert、nova-consoleauth、nova-scheduler和nova-conductor均开启）

# nova-manage service list

Compute节点：

第一步、安装nova组件

# apt-get install nova-compute-kvm python-guestfs

第二步、make the current kernel readable for qemu and libguestfs

# dpkg-statoverride --update --add root root 0644 /boot/vmlinuz-$(uname -r)

第三步、Enable this override for all future kernel updates

cat > /etc/kernel/postinst.d/statoverride <

第四步、配置 /etc/nova/nova.conf

cat >/etc/nova/nova.conf <

第五步、删除nova.sqlite数据库

# rm /var/lib/nova/nova.sqlite

第六步、配置/etc/nova/nova-compute.conf，使用qemu而非kvm。

# vi /etc/nova/nova-compute.conf[DEFAULT]compute_driver=libvirt.LibvirtDriver[libvirt]virt_type=qemu

第七步、重启服务

# service nova-compute restart

第八步、检查nova服务是否安装成功（确保nova-cert、nova-consoleauth、nova-scheduler、nova-conductor和nova-compute均开启）

# nova-manage service list

6、安装neutron(网络服务)

controller节点：

第一步、安装neutron 组件

# apt-get install neutron-server neutron-plugin-ml2

第二步、配置/etc/neutron/neutron.conf

需要配置包括数据库，认证，消息代理，拓扑改变通知和plugin。

数据库连接

默认为：onnection = sqlite:var/lib/neutron/neutron.sqlite，用以下命令修改

sed -i '/connection = .*/{s|sqlite:///.*|mysql://'"neutron"':'"$MYSQL_PASS"'@'"$CONTROLLER_IP"'/neutron|g}' \        /etc/neutron/neutron.conf

身份验证

sed -i 's/# auth_strategy = keystone/auth_strategy = keystone/g' \        /etc/neutron/neutron.conf sed -i -e " s/%SERVICE_TENANT_NAME%/service/g; s/%SERVICE_USER%/neutron/g; \          s/%SERVICE_PASSWORD%/$SERVICE_PASSWORD/g; \          s/auth_host = 127.0.0.1/auth_host = $CONTROLLER_IP/g" /etc/neutron/neutron.conf

配置消息代理

sed -i -e " s/# rpc_backend = neutron.openstack.common.rpc.impl_kombu/rpc_backend = neutron.openstack.common.rpc.impl_kombu/g; \          s/# rabbit_host = localhost/rabbit_host = $CONTROLLER_IP/g; \          s/# rabbit_password = guest/rabbit_password = $SERVICE_PASSWORD/g; \          s/# rabbit_userid = guest/rabbit_userid = guest/g" \          /etc/neutron/neutron.conf

配置网络拓扑改变通知compute

service_id=`keystone tenant-get service | awk '$2~/^id/{print $4}'` sed -i -e " s/# notify_nova_on_port_status_changes = True/notify_nova_on_port_status_changes = True/g; \            s/# notify_nova_on_port_data_changes = True/notify_nova_on_port_data_changes = True/g; \            s/# nova_url = http:\/\/127.0.0.1:8774\/v2/nova_url = http:\/\/$MASTER:8774\/v2/g; \            s/# nova_admin_username =/nova_admin_username = nova/g; \        s/# nova_admin_tenant_id =/nova_admin_tenant_id = $service_id/g; \            s/# nova_admin_password =/nova_admin_password = $SERVICE_PASSWORD/g; \        s/# nova_admin_auth_url =/nova_admin_auth_url = http:\/\/$MASTER:35357\/v2.0/g" \            /etc/neutron/neutron.conf 其中，# keystone tenant-get service用来获得service租户的id

配置ML2 plug-in

sed -i -e 's/core_plugin = neutron.plugins.ml2.plugin.Ml2Plugin/core_plugin = ml2/g' /etc/neutron/neutron.confsed -i -e 's/# service_plugins =/service_plugins = router/g' /etc/neutron/neutron.confsed -i -e 's/# allow_overlapping_ips = False/allow_overlapping_ips = True/g' /etc/neutron/neutron.conf

第三步、配置/etc/neutron/plugins/ml2/ml2_conf.ini

ML2代理使用OVS代理来创建虚拟网络架构。然而，controller节点不需要OVS代理或服务，因为controller节点不处理虚拟机网络通信。

在[ml2]模块，[ml2_type_gre]模块增加以下配置，并增加[securitygroup]新模块的配置。

[ml2]type_drivers = gretenant_network_types = gremechanism_drivers =openvswitch[ml2_type_gre]tunnel_id_ranges =1:1000[securitygroup]# Controls if neutron security group is enabled or not.# It should be false when you use nova security group.firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriverenable_security_group = True

第四步、配/etc/nova/nova.conf

默认情况，虚拟机会使用legacy networking，所以必须配置。确认按照下面配置。

network_api_class = nova.network.neutronv2.api.APIneutron_url = http://10.1.101.11:9696neutron_auth_strategy = keystoneneutron_admin_tenant_name = serviceneutron_admin_username = neutronneutron_admin_password = passwordneutron_admin_auth_url = http://10.1.101.11:35357/v2.0linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriverfirewall_driver = nova.virt.firewall.NoopFirewallDriversecurity_group_api = neutron

因为默认虚拟机使用内部防火墙服务，因为Networking有防火墙，所以需要要配置防火墙为firewall_driver = nova.virt.firewall.NoopFirewallDriver

第五步、完成安装

1. Restart the Compute services:# service nova-api restart# service nova-scheduler restart# service nova-conductor restart2. Restart the Networking service:# service neutron-server restart

network节点：

第一步、在安装OpenStack之前需要开启一些核心的网络服务，IP转发。

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.confecho "net.ipv4.conf.all.rp_filter=0" >> /etc/sysctl.confecho "net.ipv4.conf.default.rp_filter=0" >> /etc/sysctl.confsysctl -p

第二步、安装neutron组件

# apt-get install neutron-plugin-ml2 neutron-plugin-openvswitch-agentopenvswitch-datapath-dkms \neutron-l3-agent neutron-dhcp-agent

Tip:

【查看Ubuntu版本root@ubuntu:~# cat /etc/issueUbuntu 12.04.2 LTS \n \lroot@ubuntu:~# lsb_release -aNo LSB modules are available.Distributor ID: UbuntuDescription:    Ubuntu 12.04.2 LTSRelease:        12.04Codename:       preciseroot@ubuntu:~# uname -aLinux ubuntu 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux如果Ubuntu用的Linux内核版本在3.11或以上就不需要安装openvswitch-datapath-dkms package包。】

第三步、配置/etc/neutron/neutron.conf

[DEFAULT]模块和[keystone_authtoken]模块

[DEFAULT]...auth_strategy = keystone rpc_backend = neutron.openstack.common.rpc.impl_kombu rabbit_host = controller rabbit_password = RABBIT_PASS core_plugin = ml2 service_plugins = router allow_overlapping_ips = True

[keystone_authtoken]...auth_uri = http://controller:5000auth_host = controllerauth_protocol = httpauth_port = 35357admin_tenant_name = serviceadmin_user = neutronadmin_password = NEUTRON_PASS

注释掉[service_providers]所有行

第四步、配置L3agent /etc/neutron/l3_agent.ini

[DEFAULT]...interface_driver = neutron.agent.linux.interface.OVSInterfaceDriveruse_namespaces = Truedebug = True

第五步、配置DHCP agent /etc/neutron/dhcp_agent.ini

[DEFAULT]...interface_driver = neutron.agent.linux.interface.OVSInterfaceDriverdhcp_driver = neutron.agent.linux.dhcp.Dnsmasquse_namespaces = Truedebug = True

第六步、配置metadata agent  /etc/neutron/metadata_agent.ini

Metadate代理为远程访问虚拟机授权提供配置信息

[DEFAULT]...auth_url = http://controller:5000/v2.0【一定要配置对】auth_region = regionOneadmin_tenant_name = serviceadmin_user = neutronadmin_password = NEUTRON_PASSnova_metadata_ip = controllermetadata_proxy_shared_secret = METADATA_SECRET

下面两步在controller节点完成

1、编辑/etc/nova/nova.conf在[DEFAULT]加上, METADATA_SECRET为对应密码，我改为password。

[DEFAULT]...service_neutron_metadata_proxy = trueneutron_metadata_proxy_shared_secret = METADATA_SECRET

2、在controller节点，重启Compute API服务。

# service nova-api restart

第七步、配置ML2 plug-in网络/etc/neutron/plugins/ml2/ml2_conf.ini

在[ml2]模块增加

[ml2]...type_drivers = gretenant_network_types = gremechanism_drivers = openvswitch

在[ml2_type_gre]模块增加

[ml2_type_gre]...    tunnel_id_ranges = 1:1000

新增[ovs]模块并增加下面内容，其中INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS替换为network节点虚拟机tunnels网络的网卡ip地址。这里为10.0.1.21

[ovs]...local_ip = INSTANCE_TUNNELS_INTERFACE_IP_ADDRESStunnel_type = greenable_tunneling = True

新增[securitygroup]模块并增加

[securitygroup]...firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriverenable_security_group = True

第八步，配置OVS服务

OVS提供底层虚拟机网络架构。br-int处理虚拟机内部网络通信。br-ext处理虚拟机外部网络通信。br-ext需要一个port在物理外网网卡来为虚拟机提供外部网络通信。这个port 桥接虚拟网络和物理外网。

重启OVS服务。

# service openvswitch-switch restart

添加集成网桥

# ovs-vsctl add-br br-int

添加外部网桥

# ovs-vsctl add-br br-ex

添加外部网卡借以通外网

将INTERFACE_NAME  替换为当前网卡的名字。比如eth2或者ens256.我的是eth2.

# ovs-vsctl add-port br-ex INTERFACE_NAME

然后要配置network节点的/etc/network/interface中的br-ex网卡，完整内容如下：

# This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The loopback network interfaceauto loiface lo inet loopbackauto eth0iface eth0 inet staticaddress 10.1.101.21netmask 255.255.255.0gateway 10.1.101.254dns-nameservers 10.1.101.51auto eth1iface eth1 inet staticaddress 10.0.1.21netmask 255.255.255.0# The external network interfaceauto eth2iface eth2 inet manualup ip link set dev $IFACE updown ip link set dev $IFACE downauto br-exiface br-ex inet static    address 192.168.100.21    netmask 255.255.255.0    up ip link set $IFACE promisc on    down ip link set $IFACE promisc off

重启服务

/etc/init.d/networking restart

第九步、完成安装

# service neutron-plugin-openvswitch-agent restart# service neutron-l3-agent restart# service neutron-dhcp-agent restart# service neutron-metadata-agent restart

compute节点:

第一步，开启ip转发

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.confecho "net.ipv4.conf.all.rp_filter=0" >> /etc/sysctl.confecho "net.ipv4.conf.default.rp_filter=0" >> /etc/sysctl.confsysctl -p

第二步、安装neutron组件

# apt-get install neutron-common neutron-plugin-ml2 neutron-plugin-openvswitch-agent超过3.11的Ubuntu内核版本都不需要安装openvswitch-datapath-dkms，因为我的Ubuntu版本是3.12所以不需要安装openvswitch-datapath-dkms

第三步、配置/etc/neutron/neutron.conf

需要配置认证服务，消息代理和plugin

认证

[DEFAULT]...auth_strategy = keystone

在[keystone_authtoken]模块增加下面内容，要修改NEUTRON_PASS为对应密码，我的是password。

[keystone_authtoken]...auth_uri = http://controller:5000auth_host = controllerauth_protocol = httpauth_port = 35357admin_tenant_name = serviceadmin_user = neutronadmin_password = NEUTRON_PASS

消息代理，在[DEFAULT]模块增加下面内容，注意要替换RABBIT_PASS为RabbitMQ的密码。

[DEFAULT]...rpc_backend = neutron.openstack.common.rpc.impl_komburabbit_host = controllerrabbit_password = RABBIT_PASS

配置ML2，在[DEFAULT]模块增加下面内容

[DEFAULT]...core_plugin = ml2service_plugins = routerallow_overlapping_ips = Trueverbose = True

注释掉[service_providers]模块所有行

第四步、配置ML2 plug-in /etc/neutron/plugins/ml2/ml2_conf.ini

ML2 plug-in用OVS来建立虚拟机网络。

在[ml2]模块增加

[ml2]...type_drivers = gretenant_network_types = gremechanism_drivers = openvswitch

在[ml2_type_gre]模块增加

[ml2_type_gre]...tunnel_id_ranges = 1:1000

增加[ovs]模块，并增加下面内容，注意INSTANCE_TUNNELS_INTERFACE_IP_ADDRESS要替换成compute节点虚拟机tunnels网卡的ip，这里是10.0.1.31

[ovs]...local_ip = INSTANCE_TUNNELS_INTERFACE_IP_ADDRESStunnel_type = greenable_tunneling = True

增加[securitygroup]模块，并添加下面内容。

[securitygroup]...firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriverenable_security_group = True

第五步、配置OVS服务

OVS提供底层的虚拟网络框架。Br-int处理虚拟机内部网络流量。

重启OVS服务

# service openvswitch-switch restart

添加集成网桥

# ovs-vsctl add-br br-int

第六步、配置计算服务nova使用neutron /etc/nova/nova.conf

默认虚拟机会使用legacy networking。所以要进行配置使其使用Neutron。

在[DEFAULT]模块增加下面内容：注意要修改NEUTRON_PASS为真正的密码，我的是password。

[DEFAULT]...network_api_class = nova.network.neutronv2.api.APIneutron_url = http://controller:9696neutron_auth_strategy = keystoneneutron_admin_tenant_name = serviceneutron_admin_username = neutronneutron_admin_password = NEUTRON_PASSneutron_admin_auth_url = http://controller:35357/v2.0linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriverfirewall_driver = nova.virt.firewall.NoopFirewallDriversecurity_group_api = neutron

  默认虚拟机会使用内部防火墙，这里为了让它使用Neutron的防火墙，所以配置。nova.virt.firewall.NoopFirewallDriver

第七步、完成配置

重启计算服务

# service nova-compute restart

重启OVS代理

# service neutron-plugin-openvswitch-agent restart

7、安装dashboard

 在controller节点安装dashboard

第一步、安装

# apt-get -y install apache2 libapache2-mod-wsgi openstack-dashboard memcached python-memcache

删除openstack-dashboard-ubuntu-theme这个软件包，因为它对一些功能有阻碍作用

# apt-get remove --purge openstack-dashboard-ubuntu-theme

第二步、配置/etc/openstack-dashboard/local_settings.py

修改['default']['LOCATION']中的CACHES来匹配/etc/memcached.conf的内容。

CACHES = {'default': {'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache','LOCATION' : '127.0.0.1:11211'}}

修改OPENSTACK_HOST选项为认证服务的机子。

OPENSTACK_HOST = "controller"

第三步、启动apache web服务和memcached

# service apache2 restart# service memcached restart

第四步、重启keyston服务，并同步数据库

# service keystone restart# keystone-manage db_sync

现在基本配置都已经完成，可以使用OpenStack了。

测试环境可参考

以上为我个人配置笔记，仅作参考，更详细介绍请参考官方文档。

8、增加一个compute节点

1、网卡配置

Comput2节点：两张网卡，配置eth0为管理网络，配置eth1为业务网络。

root@ubuntu:~# cat /etc/network/interfaces # This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).# The loopback network interfaceauto loiface lo inet loopbackauto eth0iface eth0 inet staticaddress 10.1.101.41netmask 255.255.255.0gateway 10.1.101.254dns-nameservers 10.1.101.51auto eth1iface eth1 inet staticaddress 10.0.1.41netmask 255.255.255.0

配置/etc/hosts如下：

root@ubuntu:~# cat /etc/hosts127.0.0.1       localhost#127.0.1.1      ubuntu#compute210.1.101.41    compute2#compute110.1.101.31    compute1#controller10.1.101.11    controller#network10.1.101.21    network# The following lines are desirable for IPv6 capable hosts::1     ip6-localhost ip6-loopbackfe00::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allrouters

compute2网卡配置好以后，在controller、network和compute节点的/etc/hosts加上相应配置。

2、确认网络配置正确

Compute节点：

# ping -c 4 openstack.org【ping外网通】

# ping -c 4 controller【ping 控制节点的管理网络通】

# ping -c 4 10.0.1.21【ping 通网络节点的tunnel网络】

# ping -c 4 10.0.1.31【ping 通compute节点的tunnel网络】

3、更新系统

#apt-get update#apt-get install python-software-properties#add-apt-repository cloud-archive:icehouse #apt-get dist-upgrade【//lxy:需要十分钟，耐心等待】

# apt-get install linux-image-generic-lts-saucy

# reboot

4、改主机名

# hostname compute2# echo "compute2" > /etc/hostname

5、设置IP转发

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.confecho "net.ipv4.conf.all.rp_filter=0" >> /etc/sysctl.confecho "net.ipv4.conf.default.rp_filter=0" >> /etc/sysctl.confsysctl -p

6、装NTP

# apt-get install -y ntp# sed -i -e " s/server ntp.ubuntu.com/server controller/g" /etc/ntp.conf # service ntp restart

7、设置环境变量

# Create the environment variablescat > /root/novarc << EOFexport OS_TENANT_NAME=adminexport OS_USERNAME=adminexport OS_PASSWORD=passwordexport MYSQL_PASS=passwordexport SERVICE_PASSWORD=passwordexport RABBIT_PASSWORD=passwordexport SERVICE_TOKEN=stackinsiderexport CONTROLLER_IP=controllerexport MASTER=computeexport LOCAL_IP="$(/sbin/ifconfig eth1 \       | awk '/inet addr/ {print $2}' | cut -f2 -d ":")"EOF # Update the global environment variables.cat /root/novarc >> /etc/profilesource /etc/profile

8、装nova-compute

# apt-get -y install nova-compute-kvm python-guestfs# 选yes # 为使得当前kernel可读对qemu和libguestfs # dpkg-statoverride --update --add root root 0644 /boot/vmlinuz-$(uname -r) # 允许将来内核更新，写个脚本#cat > /etc/kernel/postinst.d/statoverride <

配置nova.conf

cat >/etc/nova/nova.conf <

用qemu代替kvm

# sed -i 's/kvm/qemu/g' /etc/nova/nova-compute.conf # service nova-compute restart

9、装neutron

# apt-get install neutron-common neutron-plugin-ml2 neutron-plugin-openvswitch-agent \openvswitch-datapath-dkms

更新配置neutron.conf

#更新数据库连接 sed -i '/connection = .*/{s|sqlite:///.*|mysql://'"neutron"':'"$MYSQL_PASS"'@'"$CONTROLLER_IP"'/neutron|g}' \        /etc/neutron/neutron.conf #使用身份验证keystone

sed -i 's/# auth_strategy = keystone/auth_strategy = keystone/g' \        /etc/neutron/neutron.conf sed -i -e " s/%SERVICE_TENANT_NAME%/service/g; s/%SERVICE_USER%/neutron/g; \ s/%SERVICE_PASSWORD%/$SERVICE_PASSWORD/g; \ s/auth_host = 127.0.0.1/auth_host = $CONTROLLER_IP/g" /etc/neutron/neutron.conf #使用消息代理

10、配置ML plug-in

sed -i -e " s/# type_drivers = local,flat,vlan,gre,vxlan/type_drivers = gre/g; \            s/# tenant_network_types = local/tenant_network_types = gre/g; \            s/# mechanism_drivers =/mechanism_drivers = openvswitch/g; \        s/# tunnel_id_ranges =/tunnel_id_ranges = 1:1000/g;        s/# enable_security_group = True/enable_security_group = True/g" \            /etc/neutron/plugins/ml2/ml2_conf.ini cat << EOF >> /etc/neutron/plugins/ml2/ml2_conf.inifirewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriverEOF cat << EOF >> /etc/neutron/plugins/ml2/ml2_conf.ini[ovs]local_ip = $LOCAL_IPtunnel_type = greenable_tunneling = TrueEOF

11、配置OVS服务

# 重启OVS服务 # service openvswitch-switch restart # 重启neutron服务 # cd /etc/init.d/; for i in $( ls neutron-* ); do sudo service $i restart; done
