keepalive实现通知脚本

keepalive定义浮动IP地址

keepalive实现通知脚本

定义通知脚本:
  notify_master <STRING>|<QUOTED-STRING>:
    当前节点成为主节点时触发的脚本
  notify_backup <STRING>|<QUOTED-STRING>:
    当前节点转为备节点时触发的脚本
  notify_fault <STRING>|<QUOTED-STRING>:
    当前节点转为“失败”状态时触发的脚本
  notify <STRING>|<QUOTED-STRING>:
    通用格式的通知触发机制,一个脚本可完成以上三种状态的转换时的通知

示例脚本如下:

#!/bin/bash
#
contact='root@localhost'
notify() {
mailsubject="$(hostname) to be $1, vip floating"
mailbody="$(date +'%F %T'): vrrp transition, $(hostname) changed to be $1"
echo "$mailbody" | mail -s "$mailsubject" $contact
}
case $1 in
master)
notify master
;;
backup)
notify backup
;;
fault)
notify fault
;;
*)
echo "Usage: $(basename $0) {master|backup|fault}"
exit 1
;;
esac
