Shell脚本监控MySQL主从状态

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?key=bb09197b-5ff6-4928-9872-xxxxxx'

wx(){
cat > $0.msg << EOF
curl '$WEBHOOK' 
   -H 'Content-Type: application/json' 
   -d '
   {
        "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 [  $? -ne 0 ];then
        echo "Mysql is stopped $DATE" >> /data/mysql/check.log
                ERROR="ERROR:Mysql-$SLAVE_IP cannot connect
$TIME"
        wx "$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!
$TIME"
                echo "$STATUS" >> /data/mysql/check.log
                                wx "$STATUS"
                        fi
                done
     fi
}

Check_Mysql_Slave

最终报警效果如下：
