很多朋友更喜歡windows下面的可以參考下面的代碼
第一種方法：也比較普遍的方法，包括rsync、serv_u等都可以，通過查找進程中的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 ) |
第二種方法：
| @echo offfor /f "skip=3 tokens=4" %%i in ('sc query mysql') do set "zt=%%i" &goto :next:nextif /i "%zt%"=="RUNNING" (echo 已經發現該服務在運行，正在已經關閉服務net stop mysql) else (echo 該服務現在處理停止狀態，正在現在開啟服務net start mysql)exitpause |
linux系統中通過shell命令實現
檢測 MySQL 是否宕掉，如果宕掉則啟動
如果你的 MySQL 經常宕機，可以用這個腳本來實現宕機后自動啟動，把它加到 crontab 里執行即可。

| #!/bin/bash result=`/usr/bin/mysqladmin ping`expected='mysqld is alive' if [[ "$result" != "$expected" ]]thenecho "It's dead - restart mysql" # email subjectSUBJECT="[MYSQL ERROR] - Attempting to restart service" # Email To ?EMAIL="info@endyourif.com" # Email text/messageEMAILMESSAGE="/tmp/emailmessage.txt"echo "$result was received"> $EMAILMESSAGEecho "when we were expected $expected" >>$EMAILMESSAGE# send an email using /bin/mailmail -s "$SUBJECT" "$EMAIL" < $EMAILMESSAGE sudo /etc/init.d/mysql restartfi |
方法二、
| #!/bin/bash#mysql checkPORT="0"PORT=`netstat -lnt | grep 3306 | wc -l `echo $PORTif [ $PORT -eq 1 ] thenecho "mysql is running"elseecho "mysql is not running"echo "progrome reeady to start mysql "sudo service mysql start./check_mysql.shfi |
