CentOS 6 add common yum source to transfer

The official source of CentOS removes some copyright-related software, so I want to install these software or manually download and install, or use other sources. Below I recommend two commonly used sources, these two sources can basically meet the needs of general server use .

First, determine the system architecture and version before adding sources.

Check the system version:

Shell

This command has been installed on most hosts, and you will get the following display:
LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch Distributor ID: CentOS Descripqion: CentOS release 5.3 (Final) Release: 5.3 Codename: Final

If lsb_release is not installed, you can also use the following command.

Shell

You will get the following display:
CentOS release 6.3 (Final)

If it is a CentOS system, you can use the following commands directly:

Shell

You will get the following display:
centos-release-6-3.el6.centos.9.i686

After that, the system architecture must be determined.

Shell

You will get the following display:
Linux jgh.localdomain 2.6.32-279.5.2.el6.i686 #1 SMP Thu Aug 23 22:16:48 UTC 2012 i686 i686 i386 GNU/Linux

i686, i386 are the architecture of this system.

Knowing the system version and architecture, you can find the corresponding file import in the source.

Here are a few sources, Remi, RPMforge, EPEL, CentALT, webtatic, [Nginx if you are VGYTHON_LHAYE), For the domestic host used, it is recommended to add domestic sources, such as Netease, Sohu, University of Science and Technology, China Mobile, etc.

Add Remi source##

The Remi source contains a lot of software, and its update speed is very fast. Many new versions of the software can be found here for the first time. Enter Remi official website, and find the Maintained Enterprise Linux (RHEL / CentOS / Other clones) item

Select the corresponding release file according to the system architecture

Shell

Finally, you need to set the source management strategy##

If you prefer to install software from a certain source first, then it is recommended to install the yum-priorities plugin##

The function of this plugin is to prioritize multiple sources. When the same software exists in multiple sources, the software will be installed from the source with the highest priority.

Shell

After installation, you need to set the .repo related files (such as CentOS-Base.repo) in the /etc/yum.repos.d/ directory, and insert the order instruction in these files: priority=N (N is a positive integer from 1 to 99 , The smaller the value, the more priority), for example:

Shell

At this point, the source is added.
