实战案例——Ansible部署高可用OpenStack平台

案例描述

1、了解高可用OpenStack平台架构 2、了解Ansible部署工具的使用 3、使用Ansible工具部署OpenStack平台

案例目标

1、部署架构

Dashboard访问采用负载均衡方式，提供VIP地址，平台访问通过VIP地址进行访问，当其中一台控制节点异常时，别一台控制节点可以继续正常工作；MariaDB数据库采用集群式部署，控制节点间数据库相互进行同步。

2、节点规划 Ansible部署高可用OpenStack平台节点规划

IP地址

主机名

节点

172.30.14.10

controller01

控制节点1

172.30.14.11

controller02

控制节点2

172.30.14.12

compute01

计算节点1

172.30.14.13

compute02

计算节点2

192.168.1.109

server

Ansible

3、解压提供的server_bak.zip，通过哦VMware Workstation软件打开server_bak虚拟机，其作为Ansible节点。手动最小化安装4台CentOS 7.2系统的服务器，作为OpensStack节点。 【前期准备】
