Are you like me? When you first contact with Linux when the system updates the source problem get dizzy, different Linux update source configuration is not the same, in addition, because the default installation of the source is mostly foreign updates, speed relative to the domestic will be much slower, Next, we will introduce the method of updating system source in CentOS and Ubuntu system, update source with 163 update source as example CentOS update system source

First back up/etc/yum.repos.d/centos-base.repo

Mv/etc/yum.repos.d/centos-base.repo/etc/yum.repos.d/centos-base.repo.bak

Download the corresponding version of the repo file, put the/etc/yum.repos.d/(again remind the operation please do the appropriate backup)
CentOS7
CentOS6
CentOS5
Finally run the command generation cache

Yum Clean all
yum Makecache

Enjoy the flying speed. Ubuntu Update System source

Finally need to implement

sudo apt-get update
Modify the PIP update source

PIP installation default Access PyPI, but the speed of pypi for the domestic is a bit slow, there are also some of the PIP source, the benefit of the vast number of programmers
PIPY Domestic Mirror currently has:
http://pypi.douban.com/Watercress
http://pypi.hustunique.com/Huazhong University of Technology
http://pypi.sdutlinux.org/Shandong University of Technology
http://pypi.mirrors.ustc.edu.cn/China University of Science and Technology
When installing, we can manually specify the installation source as follows:

Pip-i http://pypi.douban.com/simple Install Flask

You can also configure the PIP update source if you feel that you are manually specifying the installation source for each installation
Create the. Pip folder under the home directory

mkdir ~/.pip

Then create the pip.conf file in the directory to write the following:

[Global]
Trusted-host =  pypi.douban.com
index-url = http://pypi.douban.com/simple

Here, for example, the source of watercress, because the latest PIP installation requires the use of HTTPS encryption, so you need to add trusted-host
For Windows systems, basic configuration is the same. Create or modify profiles in%homepath%\pip\pip.ini reference links:
