使用Heartbeat实现”双机热备”或者称为“双机互备”
debugfile /var/log/ha-debug #用于记录heartbeat的调试信息 logfile /var/log/ha-log #用于记录heartbeat的日志信息 logfacility local0 #系统日志级别 keepalive 2 #设定心跳(监测)间隔时间，默认单位为秒 warntime 10 #＃警告时间，通常为deadtime时间的一半 deadtime 30 # 超出30秒未收到对方节点的心跳，则认为对方已经死亡 initdead 120 #网络启动时间，至少为deadtime的两倍。 hopfudge 1 #可选项：用于环状拓扑结构,在集群中总共跳跃节点的数量 udpport 694 #使用udp端口694 进行心跳监测 ucast eth1 192.168.9.6 #采用单播，进行心跳监测，IP为对方主机IP auto_failback on #on表示当拥有该资源的属主恢复之后，资源迁移到属主上 node srv5.localdomain #设置集群中的节点，节点名须与uname –n相匹配 node srv6.localdomain #节点2 ping 192.168.8.2 192.168.9.7 #ping集群以外的节点，这里是网关和另一台机器，用于检测网络的连接性 respawn root /usr/lib/heartbeat/ipfail apiauth ipfail gid=root uid=root #设置所指定的启动进程的权限
