How to change the Linux yum source?

Background

After CentOS6.3 is installed, you need to change the yum update source to avoid slow installation from a foreign site. Therefore, you can find a method to change the linux yum source from the Internet and share it with you. The principle is very simple, that is, to change the update source in the yum configuration file. Here, the configuration file in the 163 mirror site is used directly.
