如何用paramiko模块写发版机

本文小编为大家详细介绍“如何用paramiko模块写发版机”，内容详细，步骤清晰，细节处理妥当，希望这篇“如何用paramiko模块写发版机”文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。

说明：为了安全，本文敏感信息如ip、用户名密码等做了转换处理。

一、场景：每次发版时，都需要发版人一个一个文件的往生产机上拷贝，这样不仅费时，而且容易出错，降低工程师的工作积极性。

二、解决方法：需用python脚本写一个发版机，自动发版。

三、脚本实现的功能：自动合并develop_svn(开发svn)代码到online_svn（生产svn）下，自动备份远程服务器代码，手工通过ecplice编译online_svn代码，然后自动把编译后的class文件根据filelist里面的路径拷贝到生产机，并自动重启服务器上的Tomcat服务。

四、具体步骤：

1、开发提供类似如下svn文件列表：

filelist.txt里面的内容：

/trunk/src/ha/lalala/controller/BoardController.java

/trunk/src/ha/lalala/pda/PdaWaybillController.java

/trunk/WEBRoot/jsp/productReview/list.jsp

2、建立develop_svn和online_svn目录；

3、编写faban.py脚本
