~#/usr/local/python2.7/bin/python2.7
Python 2.7.3 (default, Dec 18 2013, 15:43:35) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

cd /usr/local/python2.7
python setup.py install

建立python2.7 软链

复制代码

~#mv /usr/bin/python /usr/bin/python.bak
~#ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python2.7
~#ln -s /usr/bin/python2.7 /usr/bin/python

~#yum update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

  No module named yum

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.3 (default, Dec 18 2013, 15:43:35) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
 http://yum.baseurl.org/wiki/Faq

因为centos 6.4 下yum默认使用的是python2.6

复制代码

vi /usr/bin/yum
----------------------------------------------------
#!/usr/bin/python
import sys
try:
  import yum
except ImportError:
.......

修改为

复制代码

#!/usr/bin/python2.6
........

4. 安装python-pip工具

tar zxvf pip-1.3.1.tar.gz
cd pip-1.3.1
python setup.py install
ln -s /usr/local/python2.7/bin/pip /usr/bin/pip
