※系统说明

本系统由两台Dell PowerEdge 2650（HUTUNFS1 & HUTUNFS2）和一台磁盘阵列组成，磁盘阵列

划分为ld0 & ld1两个RAID5逻辑盘（Logical Disk）。操作系统为RedHat 7.3 Linux。设置NFS HA

的目的是，当HUTUNFS1失败时HUTUNFS2自动接管。

1 安装heartbeat 1.0.3 for RedHat 7.3

http://www.ultramonkey.org/download/heartbeat/1.0.3/redhat_7.3/

heartbeat-1.0.3-1.rh.7.3.1.i386.rpm

heartbeat-ldirectord-1.0.3-1.rh.7.3.1.i386.rpm

heartbeat-pils-1.0.3-1.rh.7.3.1.i386.rpm

heartbeat-stonith-1.0.3-1.rh.7.3.1.i386.rpm

2 设置配置文件:

HUTUNFS1为master，HUTUNFS2为slave。

2.1 HUTUNFS1 192.168.0.30

/etc/ha.d/ha.cf

# define nodes in cluster

node hutunfs1

node hutunfs2

# time a system must be unreachable before considered dead (seconds)

deadtime 5

# set up for the serial heartbeat pulse

# 如果两台服务器之间用心跳线连接，heartbeat支持串行心跳监测。

#serial /dev/ttyS0

#baud 19200

# interface to run the network heartbeat pulse

udp bond0

/etc/ha.d/authkeys

auth 3

3 md5 hutuworm

/etc/ha.d/haresources

hutunfs1 192.168.0.30 Filesystem::/dev/sdc1::/ld0::ext3 nfslock nfs

hutunfs1 192.168.0.30 Filesystem::/dev/sdd1::/ld1::ext3 nfslock nfs

/etc/exports

#

# Export the shared disk, allowing read/write access and

# synchronous I/O with no write delay.

/ld0 192.168.0.*(rw,sync,no_wdelay)

/ld1 192.168.0.*(rw,sync,no_wdelay)

/etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 hutunfs1 localhost.localdomain localhost

192.168.0.30 hutunfs1

192.168.0.31 hutunfs2

2.2 HUTUNFS2 192.168.0.31

/etc/ha.d/ha.cf

/etc/ha.d/authkeys

/etc/ha.d/haresources

/etc/exports

以上四个文件与HUTUNFS1相同

/etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 hutunfs2 localhost.localdomain localhost

192.168.0.30 hutunfs1

192.168.0.31 hutunfs2

3. 在HUTUNFS1 & HUTUNFS2上运行ntsysv，确认nfs服务关闭，heartbeat服务打开。

先重起HUTUNFS1，再重起HUTUNFS2，HUTUNFS1作为master运行，HUTUNFS2作为slave运行。

当HUTUNFS1失效时，HUTUNFS2将自动接管192.168.0.30，并同时开启NFS服务。
