haproxy检查脚本（需要添加执行权限）

#!/bin/bashstatus=`ps aux|grep haproxy | grep -v grep | grep -v bash | wc -l`if [ "${status}" = "0" ]; then    /etc/init.d/haproxy startfistatus2=`ps aux|grep haproxy | grep -v grep | grep -v bash |wc -l`if [ "${status2}" = "0"  ]; then    /etc/init.d/keepalived stopfi

日志添加

默认日志存放在系统的/var/log/messages下
