The yum source in this article supports CentOS 6 series and RHEL6 series in theory.
The update method is as follows:

First, go to the yum source configuration directory.

Cd/etc/yum. repos. d

Yum source of the Backup System

Download other faster yum sources

Yum source of HKUST:
Wget http://centos.ustc.edu.cn/CentOS-Base.repo

Yum makecache

[Yasi]:
An error occurs when the last step, yum makecache, is executed:

Trying other mirror.
Error: Cannot retrieve repository metadata (repomd. xml) for repository: addons. Please verify its path and try again
The reason is that http://mirrors.163.com/centos/6/addons/x86_64/repodata/repomd.xmland the http://mirror.centos.org/centos/6/addons/x86_64/repodata/repomd.xml does not exist and may be updated. The solution is to find available URLs or comment out the items in the corresponding. repo file. Here I use the latter.

For example, in the CentOS-Base-163.repo, comment out the entire addon item
# [Addons]
# Name = CentOS-$ releasever-Addons-163.com
# Items list = http://mirrorlist.centos.org /? Release = $ releasever & arch = $ basearch & repo = addons
# Baseurl = http://mirrors.163.com/centos/?releasever/addons/?basearch/
# Gpgcheck = 1
# Pgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

Comment out the following content in CentOS-Base-sohu.repo
# [Addons]
# Name = CentOS-$ releasever-Addons-sohu.com
# Items list = http://mirrorlist.centos.org /? Release = $ releasever & arch = $ basearch & repo = addons
# Baseurl = http://mirrors.sohu.com/centos/?releasever/addons/?basearch/
# Gpgcheck = 1
# Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5CentOS-Base-sohu.repo

Then run yum makecache. Then, yum can find the package I want to install, such as gdb, subversion, and gcc-c ++.

Note:

Sometimes a package cannot be found using yum list xxx. You can try yum search xxx.
For example, yum list vim reports Error: No matching Packages to list. Yum search vim returns:
The vim-X11.x86_64: the VIM version of the vi editor for The X Window System
The vim-common.x86_64: the common files needed by any version of The VIM editor
Vim-enhanced.x86_64: A version of the VIM editor which has des recent enhancements

Vim-minimal.x86_64: A minimal version of the VIM editor

The reason is that. The solution is to find available URLs or comment out the items in the corresponding. repo file. Here I use the latter.

[Root @ wwn104 yum. repos. d] # vi CentOS-Media.repo

Change enabled = 1 to enabled = 0

Then modify: all the sources you use. For example, if sohu is used, modify sohu's:

[Root @ wwn104 yum. repos. d] # vi CentOS-Base-sohu.repo

Add the following content under [addons:

Enabled = 0
