centos 7安装pip

我发现我的centos 7 使用 
yum -y install python-pip 
返回
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.zju.edu.cn
 * extras: mirrors.yun-idc.com
 * updates: mirrors.yun-idc.com
No package python-pip available.
Error: Nothing to do

只好使用python自己装了
curl "" -o "get-pip.py"

然后
python get-pip.py

安装完毕后

 pip -V
pip 8.1.2 from /usr/lib/python2.7/site-packages (python 2.7)
