首先写一个邮件提醒python文件

#!/usr/bin/python

# -*- coding: UTF-8 -*-

import sys

import smtplib

import email.mime.multipart

import email.mime.text

server = 'smtp.163.com'

port = '25'

def sendmail(server,port,user,pwd,msg):

smtp = smtplib.SMTP()

smtp.connect(server,port)

smtp.login(user, pwd)

smtp.sendmail(msg['from'], msg['to'], msg.as_string())

smtp.quit()

print('邮件发送成功email has send out !')

if __name__ == '__main__':

msg = email.mime.multipart.MIMEMultipart()

msg['Subject'] = '服务器报警请注意！'

msg['From'] = 'python4_mail@163.com'

msg['To'] = 'longbaby1101@qq.com'

user = 'python4_mail'

pwd = 'sbalex3714'

content='%s\n%s' %('\n'.join(sys.argv[1:4]),' '.join(sys.argv[4:])) #格式处理，专门针对我们的邮件格式

txt = email.mime.text.MIMEText(content, _charset='utf-8')

msg.attach(txt)

sendmail(server,port,user,pwd,msg)

然后写自己的监控脚本

#/bin/bash

bu=`free | awk 'NR==2{print $6}'`

to=`free | awk 'NR==2{print $2}'`

mem=`expr "scale=2;$bu/$to" |bc -l | cut -d. -f2`

if(($mem >= 70))

then

msg="TIME:$(date +%F_%T)

HOSTNAME:$(hostname)

IPADDR:$(ifconfig |awk 'NR==2{print $2}')

MSG:内存high了high了！已经用了${mem}%"

echo $msg

/usr/bin/pymail.py $msg

fi

systemctl status nginx

if(($?!=0))

then

msg="TIME:$(date +%F_%T)

HOSTNAME:$(hostname)

IPADDR:$(ifconfig |awk 'NR==2{print $2}')

MSG: Nginx 进程出现异常请注意查看！"

echo $msg

/usr/bin/pymail.py $msg

fi

systemctl status nfs

if(($?!=0))

then

msg="TIME:$(date +%F_%T)

HOSTNAME:$(hostname)

IPADDR:$(ifconfig |awk 'NR==2{print $2}')

MSG: NFS 进程出现异常请注意查看！"

echo $msg

/usr/bin/pymail.py $msg

fi

之后再定时任务中写入每分钟执行一次

把两个nginx 和 nfs 服务关闭

等待一分钟之后
