在CentOS下需要用到pip，安装pip包，输入yum install Python-pip，提示No package python-pip available.Error: Nothing to do
因为没有此rpm包，此包包含在epel源里面：
输入rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
之后再安装pip,输入yum install python-pip即可。
参考：python 包管理工具pip
接触了Ruby，发现它有个包管理工具RubyGem很好用，并且有很完备的文档系统http://rdoc.info
发现Python下也有同样的工具，包括easy_install和Pip。不过，我没有细看easy_install的方法，这就简单的介绍一下Pip的安装与使用：
1，查看linux下是否有python-pip包,
[root@localhost work]# yum install python-pip
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: centos.ustc.edu.cn
* extras: centos.ustc.edu.cn
* updates: ftp.twaren.net
No package python-pip available.
Error: Nothing to do
没有此rpm包，此包包含在epel源里面
[root@localhost ~]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
Retrieving http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

安装扩展包源完成.
接着安装python-pip
[root@localhost ~]# yum install python-pip

Complete!
安装python-pip完成，在linux，shell中键入pip测试看有无该指令。
2，使用
[root@localhost ~]# pip
Usage:
pip <command> [options]
Commands:
install Install packages.
uninstall Uninstall packages.
freeze Output installed packages in requirements format.
list List installed packages.
show Show information about installed packages.
search Search PyPI for packages.
zip Zip individual packages.
unzip Unzip individual packages.
bundle Create pybundles.
help Show help for commands.
General Options:
-h, --help Show help.
-v, --verbose Give more output. Option is additive, and can be used up to 3 times.
-V, --version Show version and exit.
-q, --quiet Give less output.
--log <file> Log file where a complete (maximum verbosity) record will be kept.
--proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port.
--timeout <sec> Set the socket timeout (default 15 seconds).
--exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup.
--cert <path> Path to alternate CA bundle.
应该这些没有问题。
比如安装某个模块，redis
[root@localhost ~]# pip install redis
Downloading/unpacking redis
Downloading redis-2.8.0.tar.gz (286kB): 286kB downloaded
Running setup.py egg_info for package redis
Installing collected packages: redis
Running setup.py install for redis
Successfully installed redis
Cleaning up...
安装完成。
可以在python shell中import redis测试看是否安装成功。
