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*************";
