CentOS7系统配置国内yum源和epel源

Posted 2020-11-10

CentOS7系统配置国内yum源和epel源

1.首先进入/etc/yum.repos.d/目录下，新建一个repo_bak目录，用于保存系统中原来的repo文件

[[email protected] ~]# cd /etc/yum.repos.d/ [[email protected] yum.repos.d]# mkdir repo_bak [[email protected] yum.repos.d]# mv *.repo repo_bak/

2.在CentOS中配置使用网易和阿里的开源镜像

到网易和阿里开源镜像站点下载系统对应版本的repo文件

[[email protected] yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo [[email protected] yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo [[email protected] yum.repos.d]# ls Centos-7.repo  CentOS-Base-163.repo  repo.bak

或者手动下载repo文件并上传到/etc/yum.repos.d/目录

3.清除系统yum缓存并生成新的yum缓存

[[email protected] yum.repos.d]# ls        # 列出/etc/yum.repos.d/目录下的文件 Centos-7.repo  CentOS-Base-163.repo  repo.bak [[email protected] yum.repos.d]# yum clean all     # 清除系统所有的yum缓存 Loaded plugins: fastestmirror, langpacks 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 Cleaning repos: base extras updates Cleaning up everything Cleaning up list of fastest mirrors [[email protected] yum.repos.d]# yum makecache     # 生成yum缓存 Loaded plugins: fastestmirror, langpacks 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 base                                                                                  | 3.6 kB  00:00:00      extras                                                                                | 3.4 kB  00:00:00      updates                                                                               | 3.4 kB  00:00:00      (1/12): base/7/x86_64/filelists_db                                                    | 6.7 MB  00:00:02      (2/12): base/7/x86_64/group_gz                                                        | 156 kB  00:00:02      (3/12): base/7/x86_64/other_db                                                        | 2.5 MB  00:00:01      (4/12): base/7/x86_64/primary_db                                                      | 5.7 MB  00:00:02      (5/12): extras/7/x86_64/prestodelta                                                   |  51 kB  00:00:01      (6/12): extras/7/x86_64/filelists_db                                                  | 494 kB  00:00:02      (7/12): extras/7/x86_64/other_db                                                      |  86 kB  00:00:00      (8/12): extras/7/x86_64/primary_db                                                    | 130 kB  00:00:01      (9/12): updates/7/x86_64/prestodelta                                                  | 406 kB  00:00:01      (10/12): updates/7/x86_64/filelists_db                                                | 2.1 MB  00:00:01      (11/12): updates/7/x86_64/other_db                                                    | 354 kB  00:00:00      (12/12): updates/7/x86_64/primary_db                                                  | 3.6 MB  00:00:01      Determining fastest mirrors Metadata Cache Created

4.安装epel源

[[email protected] yum.repos.d]# yum list | grep epel-release 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 epel-release.noarch                         7-9                        extras    [[email protected] yum.repos.d]# yum install -y epel-release Loaded plugins: fastestmirror, langpacks 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 Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:7-9 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================  Package                       Arch                    Version                 Repository               Size ============================================================================================================= Installing:  epel-release                  noarch                  7-9                     extras                   14 k Transaction Summary ============================================================================================================= Install  1 Package Total download size: 14 k Installed size: 24 k Downloading packages: epel-release-7-9.noarch.rpm                                                           |  14 kB  00:00:00      Running transaction check Running transaction test Transaction test succeeded Running transaction   Installing : epel-release-7-9.noarch                                                                   1/1    Verifying  : epel-release-7-9.noarch                                                                   1/1  Installed:   epel-release.noarch 0:7-9                                                                                   Complete! [[email protected] yum.repos.d]# ls            # epel源安装成功，比原来多了一个epel.repo和epel-testing.repo文件 Centos-7.repo  CentOS-Base-163.repo  epel.repo  epel-testing.repo  repo.bak

5.使用阿里开源镜像提供的epel源

[[email protected] yum.repos.d]# wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo    # 下载阿里开源镜像的epel源文件 --2018-03-08 20:22:14--  http://mirrors.aliyun.com/repo/epel-7.repo Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 183.2.199.237, 113.96.109.95, 113.96.109.93, ... Connecting to mirrors.aliyun.com (mirrors.aliyun.com)|183.2.199.237|:80... connected. HTTP request sent, awaiting response... 200 OK Length: 1084 (1.1K) [application/octet-stream] Saving to: ‘/etc/yum.repos.d/epel-7.repo’ 100%[=================================================================================================>] 1,084       --.-K/s   in 0s       2018-03-08 20:22:14 (130 MB/s) - ‘/etc/yum.repos.d/epel-7.repo’ saved [1084/1084] [[email protected] yum.repos.d]# ls CentOS7-Base-163.repo  Centos-7.repo  epel-7.repo  epel.repo  epel-testing.repo  repo_bak

6.再次清除系统yum缓存，并重新生成新的yum缓存
