Adjust the priority of the yum repository in CentOS 7

Adjust the priority of the yum repository in CentOS 7

Purpose: To enable yum to search for a DVD warehouse first and then another warehouse.

The procedure is as follows:

1. Install the priority plug-in: [plain] view plaincopy

1. # Yuminstallyum-plugin-priorities

2. Modify the CentOS-Media.repo file and add a line at the end of the file:

[Plain] view plaincopy

1. Priority = 1

3. Modify the CentOS-Base.repo file and add a line at the end of each section: [plain] view plaincopy

1. Priority = 1

4. refactor the yum cache [plain] view plaincopy

1. # Yumcleanall
2. # Yummakecache

When you use yum to install the software package, you will find that the system first searches for software from the CentOS installation disc or Everything disc.
