利用python脚本程序监控文件被修改

1. 需求：

利用python编写监控程序，监控一个文件目录，当目录下的文件发生改变时，实现有修改就发报警邮件

邮件使用QQ邮箱，需要开启smtp，使用手机发生短信，腾讯会给你发邮箱密码。如下所示：

把这个密码填到程序中。

python版本

[root@ftp day01]# python
Python 2.6.6 (r266:84292, Jul 23 2015, 15:22:56)

2.程序代码如下：

[root@ftp day01]# cat montest.py  sendMail.py

#!/usr/bin/env python
#coding:utf-8
import sys
import pyinotify
from sendMail import send
try:
    path = sys.argv[1]
except:
    raise(AttributeError("has no attribute path"))
class MyEvent(pyinotify.ProcessEvent):
    def process_IN_MODIFY(self,event):
        '''print("hell world")
        print ("%s be chandg "event.name)
        '''
        content = "%s be change" %(path+event.name)
        title = "refine's mail"
        froms = "11111111@qq.com"  '''发邮件账号'''
        to = "22222222@qq.com"      '''接收邮件账号'''

        send(content,title,froms,to)
        print (content)

def main(path):
    vm = pyinotify.WatchManager()
    vm.add_watch(path,pyinotify.ALL_EVENTS,rec = True)
    event = MyEvent()
    notifier = pyinotify.Notifier(vm,event)
    notifier.loop()
main(path)

#!/usr/bin/env python
#coding:utf-8

import smtplib
from email.mime.text import MIMEText

def send(content,title,froms,*to):
    msg = MIMEText(content,"plain","utf-8")
    msg["Subject"]= title
    msg["From"]= froms
    msg["To"] = ",".join(to)

    server = smtplib.SMTP_SSL("smtp.qq.com",465)
    server.login("11111111@qq.com","zqyricvcbed") '''此处写你发邮件的qq和密码'''
    server.sendmail(froms,list(to),msg.as_string())
    server.quit()
    
if __name__ == '__main__':
     '''
     content = "hello I am alvin"
     title = "alvin's  mail"
     froms = "11111111@qq.com"
     to = "22222222@qq.com"
     send(content,title,froms,to)
     '''

3.实战监控 /etc 目录下的文件修改

修改/etc/passwd文件

python脚本程序检查到修改后发送报警邮件
