利用shell+短信實現簡單mysql雙向同步監控

 原理、腳本都很簡單，就是截取同步狀態的Slave_IO_Running和Slave_SQL_Running兩個值是否都爲Yes。若是其中不是，就發短信報警。

 

[root@mysqlb script]# cat Check_Mysql_Slave_Replication.sh
#!/bin/sh

. /etc/profile

db_user=reed
db_paasswd=reed
LogPath=/root/script/Check_Mysql_Slave_Replication_Log
[ ! -d $LogPath ] && mkdir -p $LogPath

cd $LogPath

Slave_IO_Running=$(/usr/local/mysql/bin/mysql -u$db_user -p$db_paasswd -e"show slave status \G"|grep 'Slave_IO_Running'|cut -d':' -f 2|cut -d' ' -f 2)
Slave_SQL_Running=$(//usr/local/mysql/bin/mysql -u$db_user -p$db_paasswd -e"show slave status \G"|grep 'Slave_SQL_Running'|cut -d':' -f 2|cut -d' ' -f 2)

FUNC()
{
        echo "[INFO]$(date +'%F %T') begin to monitor mysql replication..."
        if [ "$Slave_IO_Running" == "Yes" ] && [ "$Slave_SQL_Running" == "Yes" ];then
                echo "[INFO]$(date +'%F %T') mysql replication is ok!"
        else
                echo "[ERROR]$(date +'%F %T') fuck!mysql24 replication is failed..."
                #調用本身寫的發短信腳本
                /root/script/info_takeok.sh "fuck!mysql24 replication is failed"
        fi
}
FUNC >>Check_Mysql_Slave_Replication$(date +'%F').log

最後寫到crontab裏面，一分鐘檢測一次
