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
|
1 2 3 |
[root@bogon ~]# cd /etc/yum.repos.d/ [root@bogon yum.repos.d]# mkdir repo_bak [root@bogon 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.
|
1 2 3 4 5 6 7 8 |
#CentOS7 [root@bogon yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo #也可以采用curl命令获取 #curl -O http://mirrors.aliyun.com/repo/Centos-7.repo #wget http://mirrors.aliyun.com/repo/Centos-8.repo [root@bogon yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo [root@bogon 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.安装epel源
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 |
[root@bogon 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 [root@bogon 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! [root@bogon 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 |
4.使用阿里开源镜像提供的epel源
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
[root@bogon 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, ...

5.清除系统yum缓存，并重新生成新的yum缓存
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 |

6.查看系统可用的yum源和所有的yum源
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 |
