一個監控Squid運行進程數並自動重啟的簡潔Shell指令碼分享_linux shell

複製代碼 代碼如下:

#!/bin/sh

while sleep 30

do

SquidNum=`ps -ef|grep squid|grep -v grep|wc -l`

#HttpNum=`netstat -an|grep 0.0.0.0:80|grep -v grep|wc -l` #80狀態

if [ $SquidNum != 3 ] ; then

/etc/rc3.duid start

adddate=`date +%Y-%m-%d`" "`date +%H:%M:%S`

echo "$adddate squid started!" >> /home/resquid.log

fi

#超過5000個http請求就重啟squid服務

HttpNum=`netstat -an|grep 80|grep -v grep|wc -l`

if [ $HttpNum -gt 5000 ] ; then

/etc/rc3.duid restart

adddate=`date +%Y-%m-%d`" "`date +%H:%M:%S`

echo "$adddate http out 5000 squid started!" >> /home/resquid.log

fi

done
