分享一个Linux下，监控MySQL主从状态及配合企业微信机器人报警的Shell脚本
- SLAVE_IP：为监控的主机IP
- USER：为msyql用户
- PASSWORD：为mysql密码
- WHEREIS_MYSQL：为mysql命令路径
- WEBHOOK：为企业微信机器人Webhook地址
- wx()：为企业微信机器人函数
- Check_Mysql_Slave()：为监控脚本主函数
#! /bin/bash
#
source /etc/profile
export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
SLAVE_IP=`ip add | grep inet | grep brd | awk -F / '{print $1}' | awk -F " " '{print $2}' | awk 'NR==1'`
USER=monitor
PASSWORD=xxxxxx
TIME=`date`
WHEREIS_MYSQL=/opt/mysql/bin/mysql
WEBHOOK='https://qyapi.weixin.qq.com/cgi-bin/webhook/send"msgtype": "text",
"text": {
"content": "$1",
}
}'
EOF
sh $0.msg && rm -rf $0.msg
}
Check_Mysql_Slave()
{
$WHEREIS_MYSQL -u$USER -p$PASSWORD -h$SLAVE_IP -e "select version();" >/dev/null 2>&1
if [ $"Mysql is stopped $DATE" /data/mysql/check.log
ERROR="ERROR:Mysql-$SLAVE_IP cannot connect\n$TIME"
wx "$ERROR"
else
#echo "1" /data/mysql/check.log
IO_SQL_STATUS=`$WHEREIS_MYSQL -u$USER -p$PASSWORD -h$SLAVE_IP -e "show slave status \G" 2>/dev/null | awk '/Slave_.*_Running:/{print $1$2}'`
for i in $IO_SQL_STATUS;do
THREAD_STATUS_NAME=${i%:*}
THREAD_STATUS=${i#*:}
if [ "$THREAD_STATUS" != "Yes" ];then
STATUS="ERROR:Mysql-$SLAVE_IP $THREAD_STATUS_NAME status is $THREAD_STATUS!\n$TIME"
echo "$STATUS" /data/mysql/check.log
wx "$STATUS"
fi
done
fi
}
Check_Mysql_Slave
最终报警效果如下：
