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。

#!/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 "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
