shell监控MySQL服务是否正常

监控MySQL服务是否正常，通常的思路为：检查3306端口是否启动，ps查看mysqld进程是否启动，命令行登录mysql执行语句返回结果，

[root@hujiali1~]#netstat-tunpl|grep3306|wc-l

1

[root@hujiali1~]#ps-ef|grepmysql|grep-vgrep|wc-l

2

[root@hujiali1~]#chmod+xcheck_mysql.sh

[root@hujiali1~]#./check_mysql.sh

MySQLisrunning

[root@hujiali1~]#catcheck_mysql.sh

#!/bin/bash

#writtenbymofansheng@2015-10-15

port=`netstat-nlt|grep3306|wc-l`

if[$port-ne1]

then

/etc/init.d/mysqldstart

else

echo"MySQLisrunning"

fi

[root@hujiali1~]#chmod+xcheck_mysql2.sh

[root@hujiali1~]#catcheck_mysql2.sh

#!/bin/bash

#writtenbyhujianli

process=`ps-ef|grepmysql|grep-vgrep|wc-l`

if[$process-ne2]

then

/etc/init.d/mysqldstart

else

echo"MySQLisrunning"

fi

端口号和进程都检测到才算mysql启动成功

#!/bin/bash

port=`

netstat

-nlt|

then

start

fi

使用客户端登录mysql执行命令，查看返回结果测试服务是否启动，理论上此方法最可靠。

#catcheck_db_client.sh
