wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
tar zxf Python-2.7.3.tgz
cd Python-2.7.3
./configure –prefix=/usr/local/python27
make
make install
ln -sf /usr/local/python27/bin/python2.7 /usr/local/bin/python2.7
virtualenv --python=python2.7 --unzip-setuptools env
如果提示缺少zlib或者https，安装yum install zlib-devel openssl-devel 之后再重新编译python
yum install mysql-python
vi ~/.bash_profile
在最后添加 export PYTHONPATH=/usr/lib/python2.5/site-packages/
重新登陆即可生效，只对登陆用户生效
