Full configuration of Linux yum Source

Full configuration of Linux yum Source
I. Introduction yum is mainly used to conveniently Add/delete/update RPM packages. It automatically solves the dependency problem of packages and facilitates management of a large number of system updates, the concept is to use a central repository to manage the relationship between some or even a distribution application, and perform related upgrade, installation, and deletion operations based on the calculated software dependency, this reduces the dependencies problem that Linux users have always suffered. Multiple resource libraries (Repository) and simple configuration files (/etc/yum. conf) automatically solves the dependency problem when the rpm package is added or deleted, and maintains consistency with the RPM database. 2. Software Installation Method and Policy http://seisman.info/how-to-install-softwares-under-centos-7.html 3. Official source configuration CentOS6 official source, steps are as follows: 1) execute the following command to view the yum package rpm-qa | grep yum 2) run the following command to uninstall the original source rpm-qa | grep yum | xargs rpm-e -- nodeps 3) download the new yum package wget http://centos.ustc.edu.cn/centos/6/ OS /i386/Packages/yum-3.2.29-22.el6.centos.noarch.rpmwget wget Http://centos.ustc.edu.cn/centos/6/ OS /i386/Packages/yum-plugin-fastestmirror-1.1.30-10.el6.noarch.rpm 4) execute the following command to install the new yum package rpm-ivh yum-* 5) download the configuration source for yum wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo to modify the configuration source, the modified link is as follows: http://download.csdn.net/detail/u011640816/9252933 6) run the following command to update cd/etc/yum. repos. d/yum update 4. The default yum software warehouse for CentOS/RHEL third-party sources is very limited. It is only limited to updates of General packages and some software packages in those disks of the release version, you can add a lot of numbers Third-party rpm software package. the RpmForge library now has more than 10000 CentOS software packages, which is considered by the CentOS community as the safest and most stable third-party software library. the steps are as follows: 1. Install the yum-priorities plug-in to set the order in which yum calls the software source. because the official software sources are relatively stable and recommended. therefore, the order of the official source is higher than that of the third source. to ensure this order, you need to install the yum-priorities plug-in. # yum-y install yum-priorities 2. After installing the yum-priorities plug-in, you need to set/etc/yum. repos. d/directory. repo-related files, such as CentOS-Base.repo, insert sequence commands in these files: priority = N (N is a positive integer from 1 to 99, the smaller the value is, the higher priority) general configuration [base], [addons], [updates], [extras] Priority = 1, [CentOSplus], [contrib] priority = 2, other third software source: priority = N (recommended N> 10), take CentOS-Base.repo as an example: ######################################## ##################### [base] name = CentOS-$ releasever-Base # Release List = http://mirrorlist.centos.org /?
