CentOS6 安装Python2.7 及 pip记录

实验室机器是 Centos6 yum完全不能升级成Python2.7，so 这几日 看了一些Python升级的东西。

CentOS切记不能自己编译，内部依赖实在太多！！！

epel !!!

epel是标配大家都懂的，这里就顺手加一下，以后查起来便利。

sudo rpm -ivh https://download.fedora.redhat.com/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm

安装SCL

这个可以提供如下几个版本的更新

yum install centos-release-SCL

官方原话

Currently, the following collections are available for CentOS 6.5 and later (package name in parenthesis):

Ruby 1.9.3 (ruby193)
Python 2.7 (python27)
Python 3.3 (python33)
PHP 5.4 (php54)

Node.js 0.10 (nodejs010)
MariaDB 5.5 (mariadb55)
MySQL 5.5 (mysql55)

安装python2.7

我这里就安装python27所有的东西了

sudo yum install python27-python*

安装完后还没结束，需要启用python27

scl enable python27 bash

pip

首先查看一下当前的pip版本

$ pip -V
pip 1.5 from /usr/lib/python2.6/site-packages/pip-1.5-py2.6.egg (python 2.6)

我这里选择最新的pip安装包

wget https://pypi.python.org/packages/source/p/pip/pip-1.5.tar.gz --no-check-certificate
tar xfz pip-1.5.tar.gz
cd pip-1.5
sudo python setup.py install

安装玩就搞定pip的升级了，同时也支持了python2.7了

pip -V
pip 1.5 from /opt/rh/python27/root/usr/lib/python2.7/site-packages/pip-1.5-py2.7.egg (python 2.7)

唉，手贱还是pip upgrade吧

pip install --upgrade pip
pip -V
pip 6.0.3 from /opt/rh/python27/root/usr/lib/python2.7/site-packages (python 2.7)

至此搞定！
