Windows服务器Pyton辅助运维

02.远程重启IIS服务器

开发环境:

Web服务器:

Windows Server 2008 R2 SP1

IIS 7.5

运维服务器:

Python 2.7.8

    组件:pywin32(219)   wmi(1.4.9)

工作内容说明:

每次排除故障的时候开发人员都会要求重启Web服务器上的IIS,有很多台IIS服务器需要重启,当然Google知道bat可以搞定这件事,但是本文用python来搞定。

实现过程:

先准备以下几个问题

使用Windows自带命令行工具如何远程重启IIS?

  1. WMI服务

          需要远程服务器安装并启动WMI服务

          如何写命令?

     2. Psexesc工具

          首先去微软网站上下载这个工具

          然后执行下面这个命令

          psexec \\192.168.1.X -u administrator -p ***** iisreset

          然后会输出如下

          bubuko.com,布布扣

Python代码的设计思路?

  1. 去搜个WMI的Python库(本文所采用
  2. 去搜个Psexec的Python库(搜到了不会用Corelabs的Impacket
  3. 直接import os 执行psexec远程命令(有问题无法看到返回信息)

 

整一个配置文件记录基本信息AppConfig.ini

 1 [DepolyFiles]
 2 
 3 LocalDir=C:\Deploy
 4 
 5 RemoteDir=E:\Deploy
 6 
 7 Servers=192.168.1.2-23|192.168.1.37
 8 
 9 UserId=administrator
10 
11 Password=*******
12 
13 UseIISRestart= false

 

Servers配置节中“|”是分隔符,可以填写多个IP,“-”符号表示连续IP。

 

然后去搜一个WMI的Python实现代码如下RemoteCommands.py

bubuko.com,布布扣
  1 __author__="*****"
  2 __date__ ="*****"

  5 import wmi

 15     config = ConfigParser.ConfigParser()
 16     config.readfp(open(pIniFileName,"rb"))
 17 
 18     LocalDir = config.get("DepolyFiles","LocalDir").strip()
 19     RemoteDir = config.get("DepolyFiles","RemoteDir").strip()
 20     Servers = config.get("DepolyFiles","Servers").strip()
 21     UserId = config.get("DepolyFiles","UserId").strip()
 22     Password = config.get("DepolyFiles","Password").strip()
 23     UseIISRestart = config.get("DepolyFiles","UseIISRestart").strip()
 24
