Check whether mysql is successfully started (bat + bash), mysqlbash

Many of my friends prefer windows. For more information, see the following code.

Method 1: Skip

@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 ) 

Method 2:

@ Echo offfor/f "skip = 3 tokens = 4" % I in ('SC query mysql') do set "zt = % I" & goto: next: nextif/I "% zt %" = "RUNNING" (echo has found that the service is RUNNING and is shutting down the service net stop mysql) else (echo this service is now processing stopped, enabling the Service net start mysql) exitpause

Use shell commands in linux

Checks whether MySQL is down. If it is down, it is started.

If your MySQL database goes down frequently, you can use this script to automatically start it after it goes down and add it to the crontab for execution.
