在安装python第三方类库时，python提供了一个类似于yum的命令easy_install，但是系统一般都是不会自带easy_install命令的，故将easy_install命令的安装方法介绍如下：
1）下载setuptools：
wget http://pypi.python.org/packages/2.4/s/setuptools/setuptools-0.6c11-py2.4.egg#md5=bd639f9b0eac4c42497034dec2ec0c2b
2）安装setuptools
sh setuptools-0.6c11-py2.4.egg
3）测试easy_install命令
