CentOS6.8升级Python2.6为Python2.7

默认的Centos的Python版本为2.6，使用pip的时候经常提示Python2.6已过期，那么还是升级到Python2.7吧。

1. 下载文件并解压

wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar -zxvf Python-2.7.13.tgz

2. 创建目录

mkdir /usr/local/python2.7

3. 开始编译安装

./configure --prefix=/usr/local/python2.7
make && make install

4. 备份原来的python

mv /usr/bin/python /usr/bin/python_old

5. 重新做软链

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

6. 校验

[root@tvzr Python-2.7.13]# python
