1.4 配置heartbeat
配置heartbeat以达到nfs主节点失效自动将所有资源切换到备用节点
1.4.1 两台nfs服务器上安装heartbeat
添加epel扩展源。官方yum源没有heartbeat
yum -y install epel-release
yum install heartbeat -y
1.4.2 将两台服务器默认配置文件拷贝到/etc/ha.d/并做更改
[root@test01 ~]# rpm -qdheartbeat|grep doc

将附件的脚本加入到/etc/ha.d/resource.d/ 下并赋予可执行权限。
1.4.3 启动两台服务器heartbeat
[root@test01 ~]#/etc/init.d/heartbeat start
[root@test01 ~]#/etc/init.d/heartbeat status
heartbeat OK [pid 5362 et al]is running on test01 [test01]...
1.4.4 测试heartbeat
全部启动heartbeat服务
[root@test01 ha.d]#/etc/init.d/heartbeat status
heartbeat OK [pid 22646 et al]is running on test01 [test01]...
[root@test02 ~]#/etc/init.d/heartbeat status
heartbeat OK [pid 13217 et al]is running on test02 [test02]...
检查test01挂载
[root@test01 ha.d]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 9.4G 1.6G 7.3G 18% /
tmpfs 495M 0 495M 0% /dev/shm
/dev/sda1 190M 36M 145M 20% /boot
/dev/drbd0 991M 1.3M 939M 1% /data
检查test02挂载
[root@test02 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 9.4G 1.6G 7.3G 18% /
tmpfs 495M 0 495M 0% /dev/shm
/dev/sda1 190M 36M 145M 20% /boot
关闭test01的heartbeat服务后再检查挂载
[root@test01 ha.d]#/etc/init.d/heartbeat stop
Stopping High-Availabilityservices: Done.
[root@test01 ha.d]# df -h
Filesystem Size Used Avail Use% Mounted on

tmpfs 495M 0 495M 0% /dev/shm
/dev/sda1 190M 36M 145M 20% /boot
再次检查test02挂载
