——安装nfs
1）安装nfs
1
| [iyunv@master ~]# yum -y install nfs-utils rpcbind
|
2）配置nfs实例
1
2
| [iyunv@master ~]# vi /etc/exports
/drbd/mynode1 192.168.254.0/24(rw,no_root_squash,no_all_squash,sync)
|
3）启动nfs [不需要设置开机启动]
1
2
3
| [iyunv@master ~]# exportfs -r
[iyunv@master ~]# service rpcbind restart
[iyunv@master ~]# service nfs restart
|
——客户端挂载
1
| [iyunv@Client ~]# mount -t nfs 192.168.254.200:/drbd/mynode1 /nfs/
|
——测试heartbeat故障转移
1）在master停止heartbeat
1
2
| [iyunv@master ~]# /etc/init.d/heartbeat stop
Stopping High-Availability services: 已终止
|
2）在slave上面查看日志是否切换成功
