1、下载安装包

cd /usr/local/src wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgztar -zxvf Python-2.7.13.tgz

2、编译

cd Python-2.7.13./configure --prefix=/usr/local/python27make && make install

3、置换老版本

mv /usr/bin/python /usr/bin/python_oldln -s /usr/local/python27/bin/python2.7 /usr/bin/python/usr/bin/python

4.修改yum依靠的python源，避免yum不能用

vi /usr/bin/yum

将第一行 #!/usr/bin/python 改为#!/usr/bin/python2.6 或者 #!/usr/bin/python_old

pip安装

wget https://bootstrap.pypa.io/get-pip.py --no-check-certificatepython get-pip.py
