應帥氣的領導要求，需要腳本監(jiān)控生產(chǎn)環(huán)境mysql和mongo數(shù)據(jù)庫服務。不僅要connect successful還要進行數(shù)據(jù)交互進一步確認數(shù)據(jù)庫服務正常。

代碼如下：

#!/bin/bash

#author:吳青聰

#email：wuqingcong@aliyun.com

#encoding: utf-8

#聲明四個數(shù)據(jù)，存放數(shù)據(jù)庫信息 ip、用戶、密碼、端口

declare -a host

declare -a user

declare -a passwd

declare -a port

#定義一個計數(shù)變量，初始值 0

n=0

#指明收件郵箱

mail=wuqingcong@aliyun.com

#按行讀取記錄了數(shù)據(jù)地址端口用戶名密碼信息的文件，存放進對應數(shù)組，此處文件為mysqldb_message.txt，其格式如下：

#host:192.168.0.32 user:test passwd:123456 port:3306 注意行首無空格

while read line

do

eval $(echo $line | awk -F"[: ]" '{printf("host[$n]=%s; user[$n]=%s; passwd[$n]=%s; port[$n]=%s",$2,$4,$6,$8)}')

let n++

done < mysqldb_message.txt

#檢測數(shù)據(jù)庫服務

let n–

for i in $(seq 0 $n);do

# 檢測命令

mysql -h${host[$i]} -u${user[$i]} -p${passwd[$i]} -P${port[$i]} -e "select 1 from dual;" –connect-timeout=5 &> /dev/null

#判斷執(zhí)行結果$?,為0執(zhí)行成功，為1出現(xiàn)錯誤異常

if [ $? -ne 0 ]

then

python3 mail.py $mail "mysqldb down " "please check mysql-service on ${host[$i]}"

echo "mysql$i is down"

else

# python3 mail.py $mail "mysqldb is fine " "Do not need check mysql-service on ${host[$i]} "

echo "mysql$i is fine"

fi

done

#檢測mongodb

#清空計數(shù)變量

n=0

#按行讀取記錄了數(shù)據(jù)地址端口用戶名密碼信息的文件，存放進對應數(shù)組，此處文件為mongodb_message.txt，其格式如下：

#host:127.0.0.1 user:root passwd:root port:27017 authDB:admin 注意行首無空格

while read line

do

eval $(echo $line | awk -F"[: ]" '{printf("host[$n]=%s; user[$n]=%s; passwd[$n]=%s; port[$n]=%s; db[$n]=%s",$2,$4,$6,$8,$10)}')

let n++

done < mongodb_message.txt

let n–

for i in $(seq 0 $n);do

echo "show tables maxTimeMS(5000)" | mongo ${host[$i]}:${port[$i]}/${db[$i]} -u ${user[$i]} -p ${passwd[$i]} &> /dev/null

if [ $? -ne 0 ]

then

server=${host[$i]}

python3 mail.py $mail "mongodb down " "please check mysql-service on $server"

echo "mongodb$i is down"

else

# python3 mail.py $mail "mongodb is fine " "Do not need check mysql-service on ${host[$i]}"

echo "mongodb$i is fine"

fi

done
