【工具安裝】-CentOS-安裝python包管理工具pip

     pip是python的包管理工具，pip庫中內建了很多python的開源工具包，在使用的時候直接運行pip install就可以下載並安裝註冊到python模組內，下文將會討論centos中如何安裝pip。

一、安裝pip命令

    下載pip安裝包：

[root@web1 xxx]# wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz

    解壓tar包：

[root@web1 xxx]# tar -vxf setuptools-1.4.2.tar.gz

   進入解壓包，並運行安裝命令：

[root@web1 xxx]# cd setuptools-1.4.2[root@web1 xxx]# python2.7 setup.py install

   安裝完成後，最後安裝pip：

[root@web1 xxx]# easy_install-2.7 pip

   檢測是否已經安裝成功：

[root@web1 xxx]# pip --versionpip 1.2 from /usr/local/lib/python2.7/site-packages/pip-1.2-py2.7.egg (python 2.7)

二、pip常用命令
