Due to the need to use python 2.7 version for work, Centos comes with python2.6.6. So you have to install python2.7
-------------
Originally planned to use pyenv, but the company's network is not strong and can't be downloaded, and even 15M things can't be downloaded. . . . Do not say,,, have kneeled! ! !
=====================================
Had to manually install and configure it bit by bit. . . . record.
python2.7.10 installation configuration document
download:
wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz
Environment required for installation:
yum install readline-devel -y #If python2.7.10 is not installed, the backspace key cannot be used normally after installation, etc.
Install:

tar

cd
Python-2.7.10
.
/configure
make
all
make
install
cd

The default installation location is /usr/local/bin, /usr/local/lib/python2.7
Configure python2.7.10

python -V
#Python 2.7.10

Configure the yum command so that yum still uses the original python version
Modify /usr/bin/yum
vim /usr/bin/yum
Change /usr/bin/python to /usr/bin/python2.6.6
install pip
At this time, yum cannot be used to install python plugins, it will be installed in /usr/lib/python2.6/site-packages/ by default, so it cannot be used normally after installation
First configure the environment required by python to install the plugin;
Install setuptools
download:
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-18.2.tar.gz#md5=52b4e48939ef311d7204f8fe940764f4

tar
xvf setuptools-18.2.
tar
.gz
cd
setuptools-18.2
python setup.py
install
##此时的python 命令版本:2.7.10

Let's install pip
download pip
wget https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz#md5=3823d2343d9f3aaab21cf9c917710196

tar
xf pip-7.1.2.
tar
cd
pip-7.1.2
python setup.py
install

至此pip已安装完成,可以正常使用.
# pip -V
pip 7.1.2 from /usr/local/lib/python2.7/site-packages/pip-7.1.2-py2.7.egg (python 2.7)
配置pip使用豆瓣的源

mkdir
~/.pip
#如果不存在就创建
vim ~/.pip
/pip
.conf
添加如下内容:
[global]
index-url = http:
//pypi
.douban.com
/simple
trusted-host = pypi.douban.com
|
至此pip配置完毕,可以正常使用pip来安装python的插件了。比如Ipython
pip install ipython
插件安装位置与python 2.7.10的目录下 --> /usr/local/lib/python2.7/site-packages
