fabric是个轻量级的远程维护工具，当然是结合python来使用，先看介绍：Fabric is a Python (2.5 or higher) library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.不过需要注意的是fabric只支持2.5以后python，然而rhl5默认的是2.4.3，因此需要首先升级先python。升级之前是2.4.3：[root@gtlionsdev ~]# python -VPython 2.4.3

然后接下来开始安装fabric，推荐使用pip来安装，pip是用来替代easy_install的不错的工具：$ curl -O https://raw.github.com/pypa/virtualenv/master/virtualenv.py$ python virtualenv.py my_new_env$ . my_new_env/bin/activate(my_new_env)$ pip install fabric
安装完成记得把环境变量包含/root/my_new_env/bin进PATH。-The End-
陪我们走过一段别人无法替代的记忆。在那里，
