Centos 6.5 python 2.6.6 升级到 2.7.3，并安装easy_install和pip工具过程

# python -V

Python 2.6.6

# cd /home/workspace/
# wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2[/code] 2、解压并安装
# tar xf Python-2.7.3.tar.bz
# cd Python-2.7.3
# ./configure
# make all
# make install
# make clean        #可有可无
# make distclean    #可有可无


3、替换系统默认python版本
# mv /usr/bin/python /usr/bin/python2.6.6
# ln -s /usr/local/bin/python2.7 /usr/bin/python


4、查看系统版本
# python -V

Python 2.7.3


5、替换yum程序使用的python版本
# which yum

/usr/bin/yum

#  vim /usr/bin/yum

修改内容：
#!/usr/bin/python
改为
#!/usr/bin/python2.6.6
 让yum使用老的版本的python

6、安装easy_install
# cd /home/workspace
# wget https://pypi.python.org/packages/ba/2c/743df41bd6b3298706dfe91b0c7ecdc47f2dc1a3104abeb6e9aa4a45fa5d/ez_setup-0.9.tar.gz # tar xf setup-0.9.tar.gz
# cd ez_setup-0.9 && python ez_setup.py
# which easy_install

/usr/local/bin/easy_install
 安装easy_install完成

7、安装pip
# yum install -y python-urllib3
# easy_install pip
# pip list

distribute (0.6.14)
pip (9.0.1)
setuptools (0.6rc11)
 pip安装完成

ok，到此全部安装完成！！！
