折中一下，写个脚本监控swap吧，放在crontab里面，2小时执行一次，世界安静了，再也没有烦人的报警短信了

复制代码代码如下:

#!/bin/bash 
function usage 
{ 
        echo "Usage: $0" 
        echo "e.g. $0 1500" 
        exit 
} 
if [ $# -lt 1 ];then 
        usage 
fi 
typeset -i nowSwap limitSwap 
limitSwap=$1 
nowSwap=$(free -m|grep "Swap"|sed -e "s//(.*/)/:/(.*/)//2/g"|awk '{print $2}') 
if [ $limitSwap -lt $nowSwap ];then 
        while [ 1 ] 
        do 
                if /etc/init.d/php5-fpm restart|grep -c fail 
                then echo "[$(date +%Y/%m/%d0-%H:%M)]restart php failed" 
                else 
                        echo "[$(date +%Y/%m/%d-%H:%M)]restart php successful!" 
                        break 
                fi 
        done 
fi
