檢查mysql是否成功啟動的方法(bat+bash)

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 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 
) 

第二種方法：

@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
)
exit
pause

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後自動啟動，把它加到 crontab 裡執行即可。
詳細介紹請看 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="[email protected]"
 
# 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
