监控MySQL主从状态的shell脚本
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\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:
