最近在学习python，借助fabric模块写了个批量操作服务器的脚本，在此分享给大家，如有不足之处，欢迎大家指正

准备工作：

安装python 2.6.5:

yum -y install readline*

tar xf Python-2.6.5.tar.bz2

cd Python-2.6.5

将目录下Modules/Setup.dist文件中"readline readline.c -lreadline -ltermcap"行前的注释去掉

编译安装：

./configure --enable-shared

make -j8 && make install

安装setuptools

tar xf setuptools-0.6c11.tar.gz

cd setuptools-0.6c11

python setup.py install

安装fabric

执行安装时，软件会自动从网上查找依赖的安装包并进行安装

tar xf fabric-0.9rc2.tar.gz

cd goosemo-fabric-1eacbf2

python setup.py install
