# 使用串口heartbeat
bcast eth0
# 使用网卡eth0发送心跳检测
auto_failback on
# 当主节点从故障中恢复时,将自动切换到主节点
watchdog /dev/watchdog
# 该指令是用于设置看门狗定时器，如果节点一分钟内都没有心跳，那么节点将重新启动
node HA-
node HA-
# 集群中机器的主机名，与“uname –n”的输出相同。
ping 192.168.0.254
# ping 网关或路由器来检测链路正常
respawn hacluster /usr/local/heartbeat/lib64/heartbeat/ipfail
# respawn调用 ipfail 来主动进行切换
apiauth ipfail gid=haclient uid=hacluster
# 设置启动ipfail的用户和组

# ./ResourceManager listkeys `/bin/uname -n`
测试通过后启动主节点和从节点Heartbeat：
# service heartbeat start

# rm –rf /usr/local/heartbeat/var/lib/heartbeat/hb_uuid

# ln -s /usr/libexec/pacemaker/* /usr/local/heartbeat/lib64/heartbeat/
