1.下载解压
wget http://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz
tar -zxvf Python-2.7.10.tgz
2.编译安装
cd Python-2.7.10
./configure --prefix=/usr/local/python2.7
make
make install
3.添加软连接和修改yum
mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python
vi /usr/bin/yum
#!/usr/bin/python 修改为 #!/usr/bin/python2.6.6
wq
CentOS6默认的python2.6.6升级到python2.7.10
