CentOS 6.4 升级python 2.6.6 到 python 2.7.9

python -V

cd /usr/local/src
wget http://python.org/ftp/python/2.7.9/Python-2.7.9.tgz[/code] 
3. 解压并安装

tar zxf Python-2.7.9.tgz
cd Python-2.7.9
./configure
make all
make install


4. 建立软链接

mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/bin/python2.7 /usr/bin/python


5. 由于系统默认yum调用python2.6版本，因此需重新安装python2.6.6



6. 执行安装python2.6.6

cd /usr/local/src/Python-2.6.6
rpm -Uvh --replacepkgs *.rpm


7. 重新建立链接

rm -rf /usr/bin/python
ln -s /usr/local/bin/python2.7 /usr/bin/python


8. 修改yum配置文件/usr/bin/yum

将#!/usr/bin/python 修改成 #!/usr/bin/python2.6.6


9. 完成以上步骤后，即可正常使用yum和python
