MySQL主從複製狀態監控及微信告警

MySQL主從複製狀態監控及微信告警mysql


shell腳本實現當MySQL主從狀態異常時,觸發微信告警sql


1. 設置主從監控腳本shell


vi /opt/scripts/mysql/check_repl_status.shapi


#!/bin/bashbash

host='' # Slave 機器微信

user='' # mysql 賬號(能執行show slave status便可,不須要太大的權限)curl

passwd='' # mysql 密碼ide

_msgBodys()url

{spa

local int AppID=0

local UserID=$1

local Msg="$2"

cat << EOF

{

"touser": "${UserID}",

"msgtype": "text",

"agentid": "${AppID}",

"text": {

"content": "${Msg}"

},

"safe": "0"

}

EOF

}

_sendMsgs()

{

CropID='' #微信公衆號ID

Secret='' #微信公衆號Secret

GURL="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=${CropID}&corpsecret=${Secret}"

Gtoken=$(/usr/bin/curl -s -G $GURL | grep -Po "(?<=access_token\W{3})[\w-]+")

PURL="https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=${Gtoken}"

/usr/bin/curl -s -k --data-ascii "$(_msgBodys "$1" "$2")" $PURL

}

num=`/opt/mysql/bin/mysql -u$user -p$passwd -h$host -e 'show slave status\G' |grep -E "Slave_IO_Running:|Slave_SQL_Running:"|awk '{print $2}'|grep -c Yes`

#檢查主從是否存在

if [ ! $num ]

then

msgs="Conn lost with mysql"

logtime=`date "+%Y-%m-%d %H:%M:%S"`

send_msg="XXX MySql Slave鏈接狀態\n${msgs}\n檢查時間:${logtime}"


#發送給全部人

_sendMsgs "@all" "$send_msg"


#狀態不全爲yes

elif [ $num -lt 2 ]

then

msgs=`/opt/mysql/bin/mysql -u$user -p$passwd -h$host -e 'show slave status\G' |grep -E "Master_Host:|Slave_IO_Running:|Slave_SQL_Running:"|sed s/[[:space:]]//g`

logtime=`date "+%Y-%m-%d %H:%M:%S"`

send_msg="XXX MySql主從複製狀態\n${msgs}\n檢查時間:${logtime}"

#發送給全部人

_sendMsgs "@all" "$send_msg"

fi


2. 設置crontab定時任務
