shell MySQL服务状态检查脚本示例
闲来无事,自己写了一个mysql进程检查的脚本。想想初学编程时候到处去网上搜的经历,忽然想笑。我是运维工程师,我也想说:“I am a Coder!”。
#!/bin/bash

#FUNCTION check the mysql status,if not run start mysql.

checkMysql(){
CMDCHECK=`lsof -i:3306 &>/dev/null`
Port="$?"
PIDCHECK=`ps aux|grep mysqld|grep -v grep`
Pid="$?"
if [ "$Port" -eq "0" -a "$PID" -eq 0 ];then
return 200
else
return 500
fi
}
startMysql(){
/etc/init.d/mysqld start
}
checkMysql
if [ $? == 200 ];then
echo "Mysql is running..."
else
startMysql
checkMysql
if [ $? != 200 ];then
while true
do
killall mysqld
sleep 2
[ $? != 0 ]&&break
done
startMysql
fi
fi
