很多朋友更喜欢windows下面的可以参考下面的代码
第一种方法:也比较普遍的方法,包括rsync、serv_u等都可以,通过查找进程中的exe文件,例如mysql就是mysqld.exe
@echo off for /f \"usebackq\" %%i in (`\"tasklist|find /c \"mysqld.exe\"\"`) do ( set chkstat=%%i ) if %chkstat% == 0 ( net start mysql echo ================ >> %date:~0,10%.log echo %date% %time% check mysql service stop >> %date:~0,10%.log echo restart mysql service! >> %date:~0,10%.log echo ================ >> %date:~0,10%.log )
第二种方法:
@echo off for /f \"skip=3 tokens=4\" %%i in (\'sc query mysql\') do set \"zt=%%i\" &goto :next :next if /i \"%zt%\"==\"RUNNING\" ( echo 已经发现该服务在运行,正在已经关闭服务 net stop mysql ) else ( echo 该服务现在处理停止状态,正在现在开启服务 net start mysql ) exit pause
linux系统中通过shell命令实现
检测 MySQL 是否宕掉,如果宕掉则启动
如果你的 MySQL 经常宕机,可以用这个脚本来实现宕机后自动启动,把它加到 crontab 里执行即可。
详细介绍请看 http://www.codeproject.com/Articles/988967/Mysql-Uptime-Check-Script
#!/bin/bash result=`/usr/bin/mysqladmin ping` expected=\'mysqld is alive\' if [[ \"$result\" != \"$expected\" ]] then echo \"It\'s dead - restart mysql\" # email subject SUBJECT=\"[MYSQL ERROR] - Attempting to restart service\" # Email To ? EMAIL=\"info@endyourif.com\" # Email text/message EMAILMESSAGE=\"/tmp/emailmessage.txt\" echo \"$result was received\"> $EMAILMESSAGE echo \"when we were expected $expected\" >>$EMAILMESSAGE # send an email using /bin/mail mail -s \"$SUBJECT\" \"$EMAIL\" < $EMAILMESSAGE sudo /etc/init.d/mysql restart fi
方法二、
#!/bin/bash #mysql check PORT=\"0\" PORT=`netstat -lnt | grep 3306 | wc -l ` echo $PORT if [ $PORT -eq 1 ] then echo \"mysql is running\" else echo \"mysql is not running\" echo \"progrome reeady to start mysql \" sudo service mysql start ./check_mysql.sh fi
