码农志默认的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
1 2 | 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
1 | mkdir /usr/local/python2.7 |
3. 开始编译安装
1 2 | ./configure --prefix=/usr/local/python2.7 make && make install |
4. 备份原来的python
1 | mv /usr/bin/python /usr/bin/python_old |
5. 重新做软链
1 2 | 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 |
