代码如下：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | #!/bin/bash #check MySQL_Slave Status #crontab time 00:10 MYSQLPORT=`netstat -na|grep "LISTEN"|grep "3306"|awk -F[:" "]+ '{print $4}'` MYSQLIP=`ifconfig eth0|grep "inet addr" | awk -F[:" "]+ '{print $4}'` STATUS=$(/usr/local/webserver/mysql/bin/mysql -u yuhongchun -pyuhongchun101 -S /tmp/mysql.sock -e "show slave statusG" | grep -i "running") IO_env=`echo $STATUS | grep IO | awk ' {print $2}'` SQL_env=`echo $STATUS | grep SQL | awk '{print $2}'` DATA=`date +"%y-%m-%d %H:%M:%S"`
if [ "$MYSQLPORT" == "3306" ] then
echo "mysql is running"else
mail -s "warn!server: $MYSQLIP mysql is down" yuhongchun027@163.com fi
if [ "$IO_env" = "Yes" -a "$SQL_env" = "Yes" ] then
echo "Slave is running!"else
echo "####### $DATA #########">> /data/data/check_mysql_slave.log
echo "Slave is not running!" >> /data/data/check_mysql_slave.log
echo "Slave is not running!" | mail -s "warn! $MYSQLIP MySQL Slave is not running" yuhongchun027@163.com fi |
建议每十分钟运行一次
*/10 * * * * root /bin/sh /root/mysql_slave.sh
记得在每台MySQL从机上分配一个yuhongchun的用户，权限大些也没关系，只限定在本地运行，如下所示：
| 1 2 | grant all privileges on *.* to "yuhongchun"@"127.0.0.1" identified by "yuhongchun101"; grant all privileges on *.* to "yuhongchun"@"localhost" identified by "yuhongchun101"; |
到此，关于“自动监控主从MySQL同步的SHELL脚本分享”的学习就结束了，希望能够解决大家的疑惑。理论与实践的搭配能更好的帮助大家学习，快去试试吧！若想继续学习更多相关知识，请继续关注亿速云网站，小编会继续努力为大家带来更多实用的文章！
