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 connectn$TIME" wx "$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：
