1、安装setuptools和pip
安装完python后，需要安装pip，参考网上教程有说可以用easy_install安装pip，那就先安装easy_install再安装pip，安装easy_install和pip的方法如下：

wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz
tar -vxf setuptools-1.4.2.tar.gz
cd setuptools-1.4.2
python2.7 setup.py install
easy_install-2.7 pip
ln -sv /usr/local/python27/bin/pip2.7 /usr/bin/pip27
ln -sv /usr/local/python27/bin/easy_install-2.7 /usr/bin/easy_install

参考：

此链接中还包括了安装mysql-python
下面的链接中包含了用easy_install安装virtualenv。命令为easy_install virtualenv暂时没有尝试
http://www.cnblogs.com/bluewhale/p/3347161.html
由于安装python时没有注意那么多，在安装easy_install和pip时报了错。
其实，以下的两个错误都是安装python之前没有安装好依赖包，如果真的如本文想用easy_install安装pip的话，那么最好先安装下列包，然后再配置重新编译安装python便可解决下面遇到的两个错误。

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline

很明显，报错提示解压需要zlib模块，那就安装zlib模块：
|
1
|
yum install -y zlib zlib-devel
|
安装后还需要重新编译安装python。安装成功会在python目录下生成easy_install和easy_install-2.7脚本程序，提示如下：

http://blog.csdn.net/u012538536/article/details/47360929
下面这个链接中说的是./configure时价格--with-zlib选项，不过python2.7.6中使用./configure --help并没有找到此选项，因此安装过所需的模块后，./configure时直接指定安装目录即可。
3、使用easy_install安装pip报错,报错如下：

下载错误中提示 不能识别url类型https，因为https传输是使用ssl加密传输，因此需要安装openssl-devel模块：
|
1
|
yum install -y openssl-devel
|
再次使用easy_install安装pip，安装成功后会在python目录下生成pip、pip2.7和pip2脚本程序，提示如下：
