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 mysqlecho ================ >> %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 offfor /f "skip=3 tokens=4" %%i in ('sc query mysql') do set "zt=%%i" &goto :next:nextif /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)exitpause

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。
