heartbeat_install.sh

#!/bin/bash
##因为切换后不会自动回主节点，所以脚本必需要先在主节点上运行，然后在备节点运行，才能保证heartbeat起来后vip在主节点。
##脚本需要7个参数，第一个为应用mysql/aaa,第二个为主机的角色master/slave，第三个为对方的IP，第四个为对方的主机名，第五个为虚拟 IP和app端口号，以减号相连以逗号分隔，例如10.5.31.1-10010,10.5.31.2-10011，第六个为切换后的报警对象，第七个为检测是否切换的命令,需返回status="ok"
##例：heartbeat_install.sh mysql master 10.0.0.0 hostname 10.0.0.1-mysql 13900000000 "result=\`ps aux | grep mysql | grep -v grep\`;if [ -n \"\$result\" ];then status=\"ok\";else echo \"service error\";fi"
