centos 7，pip安装
网上资料很多，我在这里整理一下吧~
pip类似RedHat里面的yum，安装Python包非常方便。本节详细介绍pip的安装、以及使用方法。
一、pip下载安装
1.1 pip下载
wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate
(可能有新手连wget 也没有安装，那我们就先安装一下， yum -y install wget)
1.2 pip安装
# tar -xzvf pip-1.5.4.tar.gz
# cd pip-1.5.4
# python setup.py install
1.3 如果pip安装后提示依然没有pip命令，需在在添加环境变量
# vim /etc/profile
在文档最后，添加:
export PATH="/usr/local/python2.7/bin:$PATH"
保存，退出
然后运行：
#source /etc/profile
1.4 如果安装失败，报错setuptools 那先安装一下setuptools
$wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-12.0.3.tar.gz#md5=f07e4b0f4c1c9368fcd980d888b29a65
安装
$ tar -zxvf setuptools-12.0.3.tar.gz
$ cd setuptools=12.0.3
$ python setup.py install
然后再执行以上步骤
二、查看pip版本
pip -V
pip 1.5.4 from /usr/local/python2.7/lib/python2.7/site-packages/pip-1.5.4-py2.7.egg (python 2.7)
