本次试验是基于Corosync和NFS对LAMP做高可用；
在一台宕机后另一台可以接替。
很多原理性的理论：HA Cluster—heartbeat v2基于crm配置有介绍；这里就不作介绍；直接进入配置阶段。
一、准备环境
| 服务器 | IP | 主机名 |
| httpd+php+mysql | 192.168.0.111 | node1.soul.com |
| httpd+php+mysql | 192.168.0.112 | node2.soul.com |
| NFS | 192.168.0.113 | nfs.soul.com |
| VIP |

一切准备就绪后；下面就是配置资源了，最繁琐的也是这里
三、配置高可用集群资源
首先做个简单的规划；需要配置哪些资源，先后次序后续启动时很重要的：
1、配置VIP
2、配置NFS共享存储
3、配置httpd服务
4、配置mysql服务
5、配置一个资源组；把上述资源加入该组
所需要的命令或需要使用的代理大致：
