centos 編譯安裝 python

1、下載源碼

    wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz

2、解壓

    tar zxvf Python-2.7.11.tgz

3、安裝

    cd Python-2.7.11

     ./configure --prefix=/usr/local/python27

    make && make install

4、修改系統默認python，並更新

    mv /usr/bin/python /usr/bin/python2.6.old

    ln -s /usr/local/python27/bin/python2.7 /usr/bin/python

5、檢測

    python -V，顯示2.7.11

6、更改yum解釋器

    由於yum使用python解釋器，輸入命令yum list，顯示

    There was a problem importing one of the Python modules

    required to run yum. The error leading to this problem was:

    No module named yum

    Please install a package which provides this module, or

    verify that the module is installed correctly.

    It's possible that the above module doesn't match the

    current version of Python

    vi /usr/bin/yum

    將文件頭部的#!/usr/bin/python改爲#!/usr/bin/python2.6
