1、先说一下什么是pip
pip 是“A tool for installing and managing Python packages.”，也就是说pip是python的软件安装工具
2、下面介绍怎么在linux下安装pip
下载pip到/usr/local/srccd /usr/local/sr
wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate
如果提示：-bash: wget: command not found
那么安装wget，执行如下：
yum -y install wget
解夺安装pip
tar -xzvf pip-1.5.4.tar.gz
cd pip-1.5.4
python setup.py install
如果安装报下面的错：
Traceback (most recent call last):
File “setup.py”, line 6, in
from setuptools import setup, find_packages
ImportError: No module named setuptools
那么就要先安装setuptools包
(1)下载setuptools包
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-2.0.tar.gz
(2)解压setuptools包
tar zxvf setuptools-2.0.tar.gz
cd setuptools-2.0
(3)编译setuptools
python setup.py build
(4)开始执行setuptools安装
python setup.py install
安装完成setuptools包后，在重新执行：
cd /usr/local/src/pip-1.5.4
python setup.py instal
至此pip安装完成
3、linux下pip使用参数
pip --help
