时间:2020-12-15 人气:0

这篇文章主要介绍了检查mysql是否成功启动的方法(bat+bash),如果mysql没有启动则开启服务，需要的朋友可以参考下

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 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。
详细介绍请看 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="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
