Windows服务器Pyton辅助运维

01．自动Copy文件（文件夹）到远程服务器所在目录

开发环境：

u  Web服务器：

Windows Server 2008 R2 SP1

IIS 7.5

u  运维服务器：

Python 2.7.8

组件：pywin32(219)  wmi(1.4.9)

工作内容说明：

生产环境中有很多台Web服务器，均为IIS环境，每次开发人员都提供站点补丁包给我进行系统升级，我需要将这些补丁包更新到所有Web服务器的指定目录下以完成系统更新的工作。

实现过程：

整一个配置文件记录基本信息AppConfig.ini

 [DepolyFiles]

 LocalDir=C:\Deploy

 RemoteDir=E:\Deploy

 Servers=192.168.1.2-23|192.168.1.37

 UserId=administrator

 Password=*******

 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RemoteCopyFiles.py

 __author__="*****"
 __date__ ="*****"

 import os
 import wmi
 import shutil
 import win32wnet
 import ConfigParser

 REMOTE_PATH = 'c:\\'

 def main():
     pIniFileName = "AppConfig.ini";

     config = ConfigParser.ConfigParser()
     config.readfp(open(pIniFileName,"rb"))

     LocalDir = config.get("DepolyFiles","LocalDir").strip()
     RemoteDir = config.get("DepolyFiles","RemoteDir").strip()
     Servers = config.get("DepolyFiles","Servers").strip()
     UserId = config.get("DepolyFiles","UserId").strip()
     Password = config.get("DepolyFiles","Password").strip()
     UseIISRestart = config.get("DepolyFiles","UseIISRestart").strip()

     print "LocalDir : "+LocalDir
     print "RemoteDir : "+RemoteDir
     print "Servers : "+Servers
     print "UserId : "+UserId
     print "Password : "+Password
     print "UseIISRestart : "+UseIISRestart

     pServerSplit = Servers.split('|');
     pServerList = list();
     for itemServer in pServerSplit:
         sServerString = itemServer.strip();
         if(sServerString.find('-')>0):
             tempList = sServerString.split('-');
             iStartValue = int(tempList[0].split('.')[3]);
             iEndValue = int(tempList[1]);
             sFrontString = tempList[0].split('.')[0]+"."+tempList[0].split('.')[1]+"."+tempList[0].split('.')[2]+".";
             while iStartValue<=iEndValue:
                 pServerList.append(sFrontString+str(iStartValue));
                 iStartValue=iStartValue+1;
         else:
             pServerList.append(sServerString);

     for webServer in pServerList:
         print '';
         sPrint = "Deploy Servers : {0} start.".format(webServer);
         print sPrint
         ip = webServer
         username = UserId
         password = Password
         server = WindowsMachine(ip, username, password)
         result = server.copy_folder(LocalDir,RemoteDir);
         sPrint = "Deploy Servers : {0} completed.".format(webServer);
         print sPrint

     print "**********Deploy Completed*************";
