openstack Queens版搭建_ubuntu

本文为双节点搭建，分为计算（IP1）和控制节点（IP2）

说明：

计算节点组件：

　　1、mysql

　　2、keystone

　　3、Nova

　　4、glance

　　5、rabbitmq

控制节点组件：

　　1、cinder

　　2、dashboard

一、修改主机名及静态IP

1、vim /etc/hostname
xxctrl(xxctrl改为目标名)

2、vim /etc/hosts
IP xxctrl(目标名)

3、hostname xxctrl （使改名生效，也可重启虚拟）

二、配置网络接口

1、vim /etc/network/interfaces

　auto eth0
   iface eth0 inet static
  address XX.XX.XX.XX(修改为自己IP1)
  netmask 255.255.240.0
  network XX.XX.0.0
  broadcast 10.18.0.255
  gateway 10.18.0.254
  dns-nameservers 61.139.2.69

2、/etc/init.d/networking restart （使网络配置生效）

三、修改为163源（可选），并更新系统及内核

1、cd /etc/apt vim sources.list

这里给大家贴出12.04的163的源，速度比较快，大家可根据自己需求选择其他的源，只要版本统一。

deb http://mirrors.163.com/ubuntu/ precise main universe restricted multiverse
deb-src http://mirrors.163.com/ubuntu/ precise main universe restricted multiverse
deb http://mirrors.163.com/ubuntu/ precise-security universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ precise-security universe main multiverse restricted
deb http://mirrors.163.com/ubuntu/ precise-updates universe main multiverse restricted
deb http://mirrors.163.com/ubuntu/ precise-proposed universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ precise-proposed universe main multiverse restricted
deb http://mirrors.163.com/ubuntu/ precise-backports universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ precise-backports universe main multiverse restricted
deb-src http://mirrors.163.com/ubuntu/ precise-updates universe main multiverse restricted

2、更新系统及内核

apt-get update && apt-get upgrade && apt-get dist-upgrade

3、增加F版源
vim sources.list
deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-proposed/folsom main
deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/folsom main

4、apt-get install ubuntu-cloud-keyring
5、apt-get update

四、配置IPv4 包转发

1、vim /etc/sysctl.conf

　　net.ipv4.ip_forward=1

2、 sysctl -p（执行使配置生效）

五、安装并配置NTP 服务

1、apt-get install ntp

2、sed -i 's/server ntp.ubuntu.com/server ntp.ubuntu.com\nserver 127.127.1.0\nfudge 127.127.1.0 stratum 10/g' /etc/ntp.conf

3、重启服务： service ntp restart

六、安装并配置MySQL 数据库

1、apt-get install -y mysql-server python-mysqldb

2、sed -i "s/127.0.0.1/0.0.0.0/" /etc/mysql/my.cnf

3、 service mysql restart

4、创建数据库并设置权限

mysql -uroot -pxxxx(自己的密码)
CREATE DATABASE nova;
CREATE DATABASE glance;
CREATE DATABASE keystone;
CREATE DATABASE cinder;
grant all privileges on *.* to root@'%' identified by 'pwd';

grant all privileges on nova.* to nova@'%' identified by 'pwd';
grant all privileges on glance.* to glance@'%' identified by 'pwd';
grant all privileges on keystone.* to keystone@'%' identified by 'pwd';
grant all privileges on cinder.* to cinder@'%' identified by 'pwd';

FLUSH PRIVILEGES;
exit;
重启数据库服务：service mysql restart

七、安装并配置RabbitMQ服务

1、vim sources.list
deb http://www.rabbitmq.com/debian/ kitten main

2、wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
3、apt-key add rabbitmq-signing-key-public.asc
4、apt-get update
5、apt-get install -y rabbitmq-server
6、查看服务状态
service rabbitmq-server status

八、安装并配置Keystone服务

1. 生成一个随机值在初始的配置中作为管理员的令牌（token）。
        openssl rand -hex 10
2、安装keystack
        apt-get install keystone
3、编辑 /etc/keystone/keystone.conf，并完成下列操作：
        a. 在 [DEFAULT] 段中，对管理员令牌进行配置。
               admin_token = ADMIN_TOKEN //将 ADMIN_TOKEN替换为上一步中生成的随机字符串。
        b. 在 [database] 段，配置数据库访问相关参数：
         [database]
          connection = mysql://keystone:KEYSTONE_DBPASS@IP/keystone
4、初始化身份认证服务的数据库,建立好的数据库是空的，需要初始化Keystone 数据库的表结构。
        service keystone restart
        keystone-manage db_sync

5、通过脚本创建租户、用户和角色并定义Services 和API Endpoints
        a. 配置管理员令牌：
           export OS_SERVICE_TOKEN=ADMIN_TOKEN //将其中的 ADMIN_TOKEN 替换为管理员令牌。例如：export OS_SERVICE_TOKEN=294a4c8a8a475f9b9836
        b.下载脚本文件
          wget https://raw.github.com/nimbula/OpenStack-Folsom-Install-guide/master/Keystone_Scripts/Without%20Quantum/keystone_basic.sh
           wget https://raw.github.com/nimbula/OpenStack-Folsom-Install-guide/master/Keystone_Scripts/Without%20Quantum/keystone_endpoints_basic.sh

6、设置环境变量
   vi /etc/profile
         export OS_NO_CACHE=1
         export SERVICE_TOKEN=ADMIN
       export OS_TENANT_NAME=admin
       export OS_USERNAME=admin(登录用户名)
       export OS_PASSWORD=pass（登录密码）
       export OS_AUTH_URL=http://IP1:5000/v2.0/
         export SERVICE_ENDPOINT=http://IP1:35357/v2.0/
7、source /etc/profile

8.修改脚本文件：
          vim keystone_basic.sh
                HOST_IP=${HOST_IP:-IP1}
              ADMIN_PASSWORD=${ADMIN_PASSWORD:-admin_pass}
              SERVICE_PASSWORD=${SERVICE_PASSWORD:-service_pass}
          vim keystone_endpoints_basic.sh
                    # Host address
                    HOST_IP=IP1
                     EXT_HOST_IP=IP1
                   # MySQL definitions
                    MYSQL_USER=keystone
                    MYSQL_DATABASE=keystone
                    MYSQL_PASSWORD=keystack_dbpass

9.修改文件执行权限
chmod +x keystone_basic.sh
chmod +x keystone_endpoints_basic.sh

10、执行脚本文件：
./keystone_basic.sh
./keystone_endpoints_basic.sh

11、验证服务
apt-get install curl openssl
curl http://IP:35357/v2.0/endpoints -H 'x-auth-token: cloud' | python -m json.tool

12、查看服务列表

   keystone user-list
   keystone service-list
   keystone endpoint-list

九、安装并配置Glance服务

1. 安装软件包：
          apt-get install glance
2. 修改配置文件
          vi /etc/glance/glance-api-paste.ini
          [filter:authtoken]
          paste.filter_factory = keystone.middleware.auth_token:filter_factory
          auth_host = IP
          auth_port = 35357
          auth_protocol = http
          admin_tenant_name = service
          admin_user = glance
          admin_password = pass

           vi /etc/glance/glance-api.conf
           verbose = True
           sql_connection = mysql://glance:username@IP/glance
           notifier_strategy = noop
           rabbit_host = IP
           rabbit_port = 5672
           rabbit_use_ssl = false
           rabbit_userid = guest
           rabbit_password = guest
           rabbit_virtual_host = /
           [filter:authtoken]
           paste.filter_factory = keystone.middleware.auth_token:filter_factory
           auth_host = IP
           auth_port = 35357
           auth_protocol = http
           admin_tenant_name = service
           admin_user = glance
           admin_password = cloud
           [paste_deploy]
           flavor = keystone

           vi /etc/glance/glance-registry.conf
           verbose = True
           sql_connection = mysql://glance: glance_dbpass@IP1/glance
           [keystone_authtoken]
           auth_host = IP
           auth_port = 35357
           auth_protocol = http
           admin_tenant_name = service
           admin_user = glance
           admin_password = service_pass
           [paste_deploy]
           flavor = keystone

          vi /etc/glance/glance-registry-paste.ini
          [filter:authtoken]
          paste.filter_factory = keystone.middleware.auth_token:filter_factory
          auth_host=IP1　　
          auth_port = 35357
          auth_protocol = http
          admin_tenant_name = service
          admin_user = glance
          admin_password = cloud

         重启glance相关服务以及初始化数据库
          service glance-api restart; service glance-registry restart
          glance-manage db_sync

3. 验证操作
         wget https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img
         source admin-openrc.sh
         glance image-create --name cloud --is-public true --container-format bare --disk-format qcow2 < cirros-0.3.0-x86_64-disk.img

glance image-list

十、安装并配置nova服务

1、安装Nova软件包
        apt-get install nova-api nova-cert novnc nova-consoleauth nova-scheduler nova-novncproxy
         nova-doc nova-conductor nova-network
2、修改配置文件
vim /etc/nova/api-paste.ini
        [filter:authtoken]
          auth_host = IP1
        auth_port = 35357
