Centos7上部署openstack ocata配置详解

之前写过一篇《openstack mitaka 配置详解》然而最近使用发现阿里不再提供m版本的源,所以最近又开始学习ocata版本,并进行总结,写下如下文档

OpenStack ocata版本官方文档:https://docs.openstack.org/ocata/install-guide-rdo/environment.html

同时如果不想一步步安装,可以执行安装脚本:http://www.cnblogs.com/yaohong/p/7251852.html

一:环境

1.1主机网络

  • 系统版本 CentOS7

  • 控制节点: 1 处理器, 4 GB 内存, 及5 GB 存储

  • 计算节点: 1 处理器, 2 GB 内存, 及10 GB 存储

   说明:

  1:以CentOS7为镜像,安装两台机器(怎样安装详见http://www.cnblogs.com/yaohong/p/7240387.html)并注意配置双网卡和控制两台机器的内存。

  2:修改机器主机名分别为:controller和compute1

#hostnamectl set-hostname hostname

  3:编辑controller和compute1的 /etc/hosts 文件

#vi /etc/hosts

  4:验证

采取互ping以及ping百度的方式

1.2网络时间协议(NTP)

[控制节点安装NTP]

NTP主要为同步时间所用,时间不同步,可能造成你不能创建云主机

#yum install chrony              (安装软件包)

#vi /etc/chrony.conf              增加

server NTP_SERVER iburst

allow ip地址网段(可以去掉,指代允许你的ip地址网段可以访问NTP)

#systemctl enable chronyd.service     (设置为系统自启动)

#systemctl start chronyd.service       (启动NTP服务)

[计算节点安装NTP]

# yum install chrony

#vi /etc/chrony.conf             `` 释除``server`` 值外的所有内容。修改它引用控制节点:

server controller iburst

# systemctl enable chronyd.service     (加入系统自启动)

# systemctl start chronyd.service       (启动ntp服务)

[验证NTP]

控制节点和计算节点分别执行#chronyc sources,出现如下

1.3Openstack包

[openstack packages安装在控制和计算节点]
  安装openstack最新的源:
  #yum install centos-release-openstack-ocata
  #yum install https://rdoproject.org/repos/rdo-release.rpm

#yum upgrade                          (在主机上升级包)
  #yum install python-openstackclient         (安装opentack必须的插件)
  #yum install openstack-selinux

1.4SQL数据库

    安装在控制节点,指南中的步骤依据不同的发行版使用MariaDB或 MySQL。OpenStack 服务也支持其他 SQL 数据库。
    #yum install mariadb mariadb-server python2-PyMySQL

         #vi /etc/mysql/conf.d/mariadb_openstack.cnf

    加入:
        [mysqld]
      bind-address = 192.168.1.73                         (安装mysql的机器的IP地址,这里为controller地址)
      default-storage-engine = innodb
      innodb_file_per_table
      collation-server = utf8_general_ci
      character-set-server = utf8
    
    #systemctl enable mariadb.service     (将数据库服务设置为自启动)
    #systemctl start mariadb.service          (将数据库服务设置为开启)
    设置mysql属性:
    #mysql_secure_installation  (此处参照http://www.cnblogs.com/yaohong/p/7352386.html,中坑一)

1.5消息队列

    消息队列在openstack整个架构中扮演着至关重要(交通枢纽)的作用,正是因为openstack部署的灵活性、模块的松耦合、架构的扁平化,反而使openstack更加依赖于消息队列(不一定使用RabbitMQ,

    可以是其他的消息队列产品),所以消息队列收发消息的性能和消息队列的HA能力直接影响openstack的性能。如果rabbitmq没有运行起来,你的整openstack平台将无法使用。rabbitmq使用5672端口。
    #yum install rabbitmq-server
    #systemctl enable rabbitmq-server.service(加入自启动)
    #systemctl start rabbitmq-server.service(启动)
    #rabbitmqctl add_user openstack RABBIT_PASS                       (增加用户openstack,密码自己设置替换掉RABBIT_PASS)
    #rabbitmqctl set_permissions openstack ".*" ".*" ".*"                   (给新增的用户授权,没有授权的用户将不能接受和传递消息)

1.6Memcached

memcache为选择安装项目。使用端口11211

[控制节点] 
  #yum install memcached python-memcached

修改/etc/sysconfig/memcached中的OPTIONS为。

OPTIONS="-l 127.0.0.1,::1,controller"

 

#systemctl enable memcached.service

 #systemctl start memcached.service

二:认证服务

2.1安装和配置

登录数据库创建keystone数据库。

【只在控制节点部署】
  #mysql -u root -p
  #CREATE DATABASE keystone;
设置授权用户和密码:
  #GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY '自定义的密码';
  #GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY '自定义的密码';
安全并配置组件:
#yum install openstack-keystone httpd mod_wsgi
#vi /etc/keystone/keystone.conf
  

[database]

connection = mysql+pymysql://keystone:密码@controller/keystone
       provider = fernet

初始化身份认证服务的数据库

# su -s /bin/sh -c "keystone-manage db_sync" keystone(一点要查看数据库是否生成表成功)
  初始化keys:
  #keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
  引导身份服务:

keystone-manage bootstrap --bootstrap-password ADMIN_PASS \

--bootstrap-admin-url http://controller:35357/v3/ \

--bootstrap-internal-url http://controller:5000/v3/ \

--bootstrap-public-url http://controller:5000/v3/ \

--bootstrap-region-id RegionOne

配置apache:
  #vi  /etc/httpd/conf/httpd.conf

ServerName controller(将ServerName 后面改成主机名,防止启动报错)

创建一个指向/usr/share/keystone/wsgi-keystone.conf文件的链接:

#ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

启动httpd:
  #systemctl enable httpd.service
  #systemctl start httpd.service

配置管理账户

#vi admin加入

export OS_USERNAME=admin

export OS_PASSWORD=123456

export OS_PROJECT_NAME=admin

export OS_USER_DOMAIN_NAME=Default

export OS_PROJECT_DOMAIN_NAME=Default

export OS_AUTH_URL=http://controller:35357/v3

export OS_IDENTITY_API_VERSION=3

2.2创建域、项目、用户和角色

创建Service Project:
  #penstack project create --domain default \

--description "Service Project" service
  创建Demo Project:
  #openstack project create --domain default \

--description "Demo Project" demo

创建 demo 用户:
  #openstack user create --domain default \

--password-prompt demo
  创建user角色:
  #openstack role create user
  将用户租户角色连接起来:
  #openstack role add --project demo --user demo user

2.3验证

vi /etc/keystone/keystone-paste.ini

从``[pipeline:public_api]``,[pipeline:admin_api]``和``[pipeline:api_v3]``部分删除``admin_token_auth

重置``OS_TOKEN``和``OS_URL`` 环境变量:

unset OS_AUTH_URL OS_PASSWORD

作为 admin 用户,请求认证令牌:
  #openstack --os-auth-url http://controller:35357/v3 \
--os-project-domain-name default --os-user-domain-name default \
--os-project-name admin --os-username admin token issue

这里会遇到错误:

Centos7上部署openstack ocata配置详解

由于是Http错误,所以返回Apache HTTP 服务配置的地方,重启Apache 服务,并重新设置管理账户:

  # systemctlrestart httpd.service

  $ export OS_USERNAME=admin

  $ export OS_PASSWORD=ADMIN_PASS

  $ export OS_PROJECT_NAME=admin

  $ export OS_USER_DOMAIN_NAME=Default

  $ export OS_PROJECT_DOMAIN_NAME=Default

  $ export OS_AUTH_URL=http://controller:35357/v3

  $ export OS_IDENTITY_API_VERSION=3

执行完后再次执行

#openstack --os-auth-url http://controller:35357/v3 \
--os-project-domain-name default --os-user-domain-name default \
--os-project-name admin --os-username admin token issue

Centos7上部署openstack ocata配置详解

 输入密码之后,有正确的输出即为配置正确。

图2.4 admin认证服务验证

作为``demo`` 用户,请求认证令牌:

#openstack --os-auth-url http://controller:5000/v3 \

--os-project-domain-name default --os-user-domain-name default \

--os-project-name demo --os-username demo token issue

Centos7上部署openstack ocata配置详解

2.4创建 OpenStack 客户端环境脚本

可将环境变量设置为脚本:
  #vi admin-openrc 加入:

export OS_PROJECT_DOMAIN_NAME=default
  export OS_USER_DOMAIN_NAME=default
  export OS_PROJECT_NAME=admin
  export OS_USERNAME=admin
  export OS_PASSWORD=123456(admin设置的密码)
  export OS_AUTH_URL=http://controller:35357/v3
  export OS_IDENTITY_API_VERSION=3
  export OS_IMAGE_API_VERSION=2

#vi demo-openrc 加入:

 export OS_PROJECT_DOMAIN_NAME=default
   export OS_USER_DOMAIN_NAME=default
   export OS_PROJECT_NAME=demo
   export OS_USERNAME=demo
   export OS_PASSWORD=123456(demo设置的密码)
   export OS_AUTH_URL=http://controller:35357/v3
   export OS_IDENTITY_API_VERSION=3
   export OS_IMAGE_API_VERSION=2

  

 

#. admin-openrc (加载``admin-openrc``文件来身份认证服务的环境变量位置和``admin``项目和用户证书)
   #openstack token issue(请求认证令牌)

三:镜像服务

3.1安装配置

建立glance数据
  登录mysql
  #mysql -u root -p (用数据库连接客户端以 root 用户连接到数据库服务器)
  #CREATE DATABASE glance;(创建 glance 数据库)
  授权
   GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
IDENTIFIED BY '密码'; (对``glance``数据库授予恰当的权限)
   GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
IDENTIFIED BY '密码';(对``glance``数据库授予恰当的权限)
  运行环境变量:
  #. admin-openrc
  创建glance用户信息:
  #openstack user create --domain default --password-prompt glance

添加 admin 角色到 glance 用户和 service 项目上
    #openstack role add --project service --user glance admin
  创建``glance``服务实体:
  #openstack service create --name glance \
 --description "OpenStack Image" image

  #CREATE DATABASE nova_api;
  #CREATE DATABASE nova; (创建 nova_api 和 nova 数据库:)
