CentOS If you change Yum Update source detailed _linux

Objective

We all know that CentOS has a very convenient software installation tool yum, but the default installation CentOS, the system is using foreign CentOS update source, which caused us to use the default update source to install or update the software when the problem is very slow.

In order to use the Yum tool to quickly install the update software, we need to configure the default Yum update source as a domestic update source. The Yum update source configuration file is located under the CentOS directory/etc/yum.repos.d/.

First of all, provide several rapid domestic update sources:

Education network resources:

1 Shanghai Jiaotong University: http://ftp.sjtu.edu.cn/centos/

Server is located in Beijing, China Education Network Center, download speed up to 10 m.

North Users and Education network users recommend, fast.

You need to manually create the Centos-base.repo file.

2 China University of Science and Technology: http://centos.ustc.edu.cn

The server is located in Hefei. Recommended by southern users. Similarly, the Cenos version is very rich and suitable for long-term use.

Non-education network resources:

1 Sohu Open source mirror server: http://mirrors.sohu.com/

Server located in Shandong province Unicom

2 Open Source server image of NetEase: Http://mirrors.163.com/centos

Speed is also good, the national user recommended

In a word, we can ping a new source before use, and see which one is used quickly.

Centos-base.repo file example, this file is in this directory/etc/yum.repos.d/

[Base]

name=centos-$releasever-base

baseurl=http://mirrors.163.com/centos/6.4/os/$basearch/

gpgcheck=1

[Updates]

name=centos-$releasever-updates

baseurl=http://mirrors.163.com/centos/6.4/updates/$basearch/

Gpgcheck =1

gpgkey=http://mirrors.163.com/centos/rpm-gpg-key-centos-6

[Addons]

name=centos-$releasever-addons

baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/

Gpgcheck=1

gpgkey=http://mirrors.163.com/centos/rpm-gpg-key-centos-6

[Extras]

name=centos-$releasever-extras

baseurl=http://mirrors.163.com/centos/6.4/extras/$basearch/

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/rpm-gpg-key-centos-6

[Centosplus]

name=centos-$releasever-plus

baseurl=http://mirrors.163.com/centos/6.4/centosplus/$basearch/

gpgcheck= 1

enabled=0

gpgkey=http://mirrors.163.com/centos/rpm-gpg-key-centos-6

As you can see from the above configuration file, you need to have a choice of configuration [base] [updates] [addons] [extras] [Centosplus] according to each home source situation.

Each item can be modified baseurl and gpgkey as the corresponding source address.

After the above configuration is complete, to empty the Yum cache and rebuild the Yum cache, execute the following command:

Yum Clean all && yum-metadata && yum clean dbcache && yum makecache && Yum Update
