在我的github https://github.com/wangganyu188 上fork了別人的fabric 安裝包，
我的測試虛擬機是centos 6.2 64位的，安裝過程如下：
#yum install git
#git clone https://github.com/wangganyu188/fabric.git
#yum install python-setuptools python-devel gcc gcc-c++
# cd fabric
# python setup install
# fab #執行此命令，如果能執行，就ok了
使用方法,簡單測試如下
需要讀取的兩個文件，做爲參數傳遞，
ip.txt
192.168.10.134
192.168.10.135
192.168.10.140
192.168.10.141
192.168.10.152
ippwd.txt
192.168.10.134 123456
