升级python2.7
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
mkdir /usr/local/python27
./configure --prefix=/usr/local/python27
Make
Make install
mv /usr/bin/python /usr/bin/python_old
ln -s /usr/local/python27/bin/python2.7 /usr/bin/python
## 修改yum脚本，使其指向旧版本的python，已避免其无法运行
# vim /usr/bin/yum
#!/usr/bin/python_old --> #!/usr/bin/python2.6
