篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了监控mysql和mongo数据库服务脚本--shell编写相关的知识,希望对你有一定的参考价值。
应帅气的领导要求,需要脚本监控生产环境mysql和mongo数据库服务。不仅要connect successful还要进行数据交互进一步确认数据库服务正常。
代码如下:
#!/bin/bash
#author:吴青聪
#email:[email protected]
#encoding: utf-8
#声明四个数据,存放数据库信息 ip、用户、密码、端口
declare -a host
declare -a user
declare -a passwd
declare -a port
#定义一个计数变量,初始值 0
n=0
#指明收件邮箱
[email protected]
#按行读取记录了数据地址端口用户名密码信息的文件,存放进对应数组,此处文件为mysqldb_message.txt,其格式如下:
#host:192.168.0.32 user:test passwd:123456 port:3306 注意行首无空格
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
#检测数据库服务
let n--
for i in $(seq 0 $n);do
# 检测命令
mysql -h${host[$i]} -u${user[$i]} -p${passwd[$i]} -P${port[$i]} -e "select 1 from dual;" --connect-timeout=5 &> /dev/null
#判断执行结果$?,为0执行成功,为1出现错误异常
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
#检测mongodb
#清空计数变量
n=0
#按行读取记录了数据地址端口用户名密码信息的文件,存放进对应数组,此处文件为mongodb_message.txt,其格式如下:
#host:127.0.0.1 user:root passwd:root port:27017 authDB:admin 注意行首无空格
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
邮件脚本为参考他人脚本,用Python编写,存放上述代码脚本同目录即可,邮件脚本代码如下:
#!/usr/bin/env python
#
# encoding: utf-8
import sys
import smtplib # 加载smtplib模块
import traceback
from email.header import Header
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.utils import parseaddr, formataddr
login_name = ‘[email protected]‘ # 发件人邮箱账号,为了后面易于维护,所以写成了变量
login_pass = ‘*******‘ # 因发博客而隐藏,自己脚本中需要指定
smtp_port = 465
def _format_addr(s):
name, addr = parseaddr(s)
return formataddr(( Header(name, ‘utf-8‘).encode(), addr))
# addr.encode(‘utf-8‘) if isinstance(addr, unicode) else addr))
def send_mail(sender, recps, Ccs, subject, htmlmsg, fileAttachment):
smtpserver = ‘smtp.exmail.qq.com‘
receivers = recps + Ccs
try:
# msg = MIMEText(htmlmsg, ‘html‘, ‘utf-8‘)
msg = MIMEMultipart()
msg.attach(MIMEText(htmlmsg, ‘html‘, ‘utf-8‘))
# msg[‘Subject‘] = subject
msg[‘Subject‘] = Header(subject, ‘utf-8‘).encode()
# msg[‘From‘] = sender
msg[‘From‘] = _format_addr(sender)
Recp = []
for recp in recps:
Recp.append(_format_addr(recp))
ccs = []
for cc in Ccs:
ccs.append(_format_addr(cc))
msg[‘To‘] = ‘,‘.join(Recp)
msg[‘Cc‘] = ‘,‘.join(ccs)
# if fileAttachment!=‘‘ :
# # 附件
for file in fileAttachment:
part = MIMEApplication(open(file, ‘rb‘).read())
attFileName = file.split(‘/‘)[-1]
part.add_header(‘Content-Disposition‘, ‘attachment‘, filename=attFileName)
msg.attach(part)
# part = MIMEApplication(open(fileAttachment, ‘rb‘).read())
# part.add_header(‘Content-Disposition‘, ‘attachment‘, filename=fileAttachment)
# msg.attach(part)
smtp = smtplib.SMTP_SSL()
smtp.connect(smtpserver, smtp_port)
smtp.login(login_name, login_pass)
# smtp.login(username, password)
smtp.sendmail(sender, receivers, msg.as_string())
smtp.quit()
print(‘SendEmail success‘)
except:
traceback.print_exc()
def main():
to=sys.argv[1]
subject=sys.argv[2]
content=sys.argv[3]
# send_mail("监控中心<[email protected]>", ["吴青聪<[email protected]>"], [], subject, "邮件内容2", "")
send_mail("监控中心<[email protected]>", [to], [], subject, content, "")
if __name__ == "__main__":
main()
