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
#!/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
注:if /etc/init.d/php5-fpm restart|grep -c fail 这一句中间的命令换成你自己的即可
