This article mainly introduces the YUM replacement source yum can not find the installation package how to do, the article is very detailed, has a certain reference value, interested friends must read it!

Among the CentOS VM provided by the company, there is only one build.repo under / etc/yum.repos.d, and the yum sources provided are only a few sources within the company, and many packages cannot be found in these sources. So to add other sources, the following post describes how to add yum feeds of China University of Science and Technology, Sohu and 163to CentOS.

The update method is as follows:

Enter the Yum source configuration directory first

Cd / etc/yum.repos.d

Backup the yum source that comes with the system

Mv CentOS-Base.repo CentOS-Base.repo.save

Download other faster yum sources

The yum source of China University of Science and Technology:

Wget http://centos.ustc.edu.cn/CentOS-Base.repo

163s yum source:

Wget http://mirrors.163.com/.help/CentOS-Base-163.repo

Yum source for sohu

Wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo

After updating the yum source, it is recommended to update it so that the operation will take effect immediately

Yum makecache

[yasi]:

An error was encountered while performing the last step, yum makecache:

Loaded plugins: fastestmirror

Repository base is listed more than once in the configuration

Repository updates is listed more than once in the configuration

Repository extras is listed more than once in the configuration

Repository centosplus is listed more than once in the configuration

Repository contrib is listed more than once in the configuration

Trying other mirror.

Http://mirror.centos.org/centos/6/addons/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22-"The requested URL returned error: 404"

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.xml and http://mirror.centos.org/centos/6/addons/x86_64/repodata/repomd.xml really don't exist and may have been updated. The solution is to find an available URL to replace it, or comment out the entire item in the corresponding .repo file. I use the latter here.

For example, in CentOS-Base-163.repo, comment out the entire addon entry

# [addons]

# name=CentOS-$releasever-Addons-163.com

# mirrorlist= 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 in CentOS-Base-sohu.repo

# [addons]

# name=CentOS-$releasever-Addons-sohu.com

# mirrorlist= 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, execute the yum makecache. After that, yum can find the package I want to install, such as gdb, subversion, gcc-c++, etc.

Note:

Sometimes you can't find a package with yum list xxx, so you can try yum search xxx.

For example, yum list vim reports Error: No matching Packages to list. Yum search vim returns:

Vim-X11.x86_64: The VIM version of the vi editor for the X Window System

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 includes recent enhancements

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