1.下载安装python2.7
安装前准备：
yum install zlib-devel openssl-devel -y
注：在编译安装python2.7之前必须先安装zlib-devel包，不然在安装setuptools时会出现以下错误：
AttributeError: ‘NoneType‘ object has no attribute ‘decompressobj‘
下载安装：
wget wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 tar xf Python-2.7.3.tar.bz2 cd Python-2.7.3 ./configure --prefix=/usr/local/python2.7 make && make install
建立软连接，使系统默认的 python指向 python2.7：
mv /usr/bin/python /usr/bin/python2.6.6 ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python
解决yum不兼容python2.7问题：
sed -i ‘s#!/usr/bin/python#!/usr/bin/python2.6.6#g‘ /usr/bin/yum
2.安装pip
安装setuptools：
wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py python ez_setup.py
下载安装pip：
wget --no-check-certificate tar zxf 1.5.5.tar.gz python setup.py install
注：编译安装python之前必须安装openssl,openssl-devel包，否则会出现以下错误：
