Python本身自带了一套工具distutils ，用于发布 Python 应用程序。但 distutils 没有提供定义其它依赖包的功能，setuptools 的真正优点并不在于实现distutils 所能实现的功能——尽管它的确增强了distutils的功能并简化了setup.py 脚本中的内容。setuptools 最大的优势是它在包管理能力方面的增强。它可以使用一种更加透明的方法来查找、下载并安装依赖包；并可以在一个包的多个版本中自由进行切换，这些版本都安装在同一个系统上；也可以声明对某个包的特定版本的需求；还可以只使用一个简单的命令就能更新到某个包的最新版本。
简单来说，Python setuptools可以看做是增强版的distutils，用来管理Python的各种包。
一般在CentOS系统安装完成后，Python编译器就已经会安装好了，对于setuptools工具的安装，可以用ea_setup.py脚本的方法，自动下载安装包并安装；也可以先下载完整的setuptools安装包，然后再单独安装。
一、以ez_setup.py脚本方式安装setuptools工具
使用ez_setup.py脚本的方法比较简单，但要注意服务器要能够联网下载软件包，安装命令为：
# cd /usr/local/src/
# wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py
# python ez_setup.py --insecure
安装的过程为：
# wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py

or: easy_install --help二、easy_install 命令的使用方式与安装举例
setuptools安装成功后，easy_install有多种使用方法：
a、通过模块名称来安装。setuptools会自动搜索PyPI 以查找最新版本的模块。如果找到的话，她会自动下载、编译和安装：例如
easy_install SQLObject
说明，安装过程可能需要权限，如果是ubuntu的话，可以加上sudo
b、指定查找页面（"download page"）来使用名称和版本信息来安装或升级一个模块:
easy_install -f http://pythonpaste.org/package_index.html SQLObject
c、从指定模块下载地址来下载模块源码并在下载成功之后编译安装
easy_install http://example.com/path/to/MyPackage-1.2.3.tgz
d、在本地已经存在的egg文件基础上来安装模块
easy_install /my_downloads/OtherPackage-3.2.1-py2.3.egg
e、升级一个已经安装的模块到最新版本，如果在PyPI中这个模块有最新版本。
easy_install --upgrade PyProtocols
f、从源码中安装模块（源码已经下载并解压到当前文件夹下）(New in 0.5a9)
easy_install .
g、模块卸载 easy_install -m package-name （比如easy_install -m pylab)
如果想删除通过easy_install安装的软件包，比如说：MySQL-python，可以执行命令：
easy_install -m MySQL-python
注：此操作会从easy-install.pth文件里把MySQL-python的相关信息抹去，剩下的egg文件，你可以手动删除。
上面这些具体细节可以参考easy install的官方网站：http://peak.telecommunity.com/DevCenter/EasyInstall
例如，用第一种方法安装SQLObject模块：
# easy_install -f http://pythonpaste.org/package_index.html SQLObject
Searching for SQLObject

三、以源码方式安装psutil模块
Python中的psutil模块能够获取系统运行进程和使用率，对于系统监控还是比较有意义的。
下面用easy_install以源码方式安装psutil模块：
# cd /usr/local/src
# wget https://pypi.python.org/packages/source/p/psutil/psutil-2.0.0.tar.gz --no-check-certificate
# tar -zxvf psutil-2.0.0.tar.gz
# cd psutil-2.0.0
# pwd
/usr/local/src/psutil-2.0.0

error: Setup script exited with error: command 'gcc' failed with exit status 1使用easy_install进行源码安装时，可能会有如下报错：用安装python模块出现error: command 'gcc' failed with exit status 1 ，明明装了gcc的，怎么会不行呢，然后发觉是failed不是not found，这说明这个错误个gcc没多 大关系，应该是缺少某些功能模块，然后谷歌了一下，先后安装了python-devel,libffi-devel后还是不行，最后发觉要安装openssl-devel才行，可如下命令行安装：
yum install gcc libffi-devel python-devel openssl-devel
过程如下：
# yum install gcc libffi-devel python-devel openssl-devel
