配置阿里云yum源(参考：http://mirrors.aliyun.com/help/centos)
1、备份
[root@bogon ~]# cd /etc/yum.repos.d/ [root@bogon yum.repos.d]# mkdir repo_bak [root@bogon yum.repos.d]# mv *.repo repo_bak/ [root@bogon yum.repos.d]# ls repo_bak
2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
[root@bogon yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo --2018-02-09 16:33:46-- http://mirrors.aliyun.com/repo/Centos-7.repo Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 124.14.2.234, 124.14.2.235, 124.14.2.217, ... Connecting to mirrors.aliyun.com (mirrors.aliyun.com)|124.14.2.234|:80... connected. HTTP request sent, awaiting response... 200 OK Length: 2573 (2.5K) [application/octet-stream] Saving to: ‘/etc/yum.repos.d/CentOS-Base.repo’ 100%[========================================================================================>] 2,573 --.-K/s in 0s 2018-02-09 16:33:47 (182 MB/s) - ‘/etc/yum.repos.d/CentOS-Base.repo’ saved [2573/2573] [root@bogon yum.repos.d]# ls CentOS-Base.repo repo_bak
3、之后运行yum clean all 清除缓存，运行 yum makecache 生成新的缓存
[root@bogon yum.repos.d]# yum clean all Loaded plugins: fastestmirror Cleaning repos: base extras updates Cleaning up everything Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos Cleaning up list of fastest mirrors [root@bogon yum.repos.d]# yum makecache Loaded plugins: fastestmirror 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/group_gz | 156 kB 00:00:00 (2/12): extras/7/x86_64/filelists_db | 636 kB 00:00:07 (3/12): extras/7/x86_64/primary_db | 166 kB 00:00:02
安装EPEL（Extra Packages for Enterprise Linux ）源
4、安装EPEL源
[root@bogon yum.repos.d]# yum list | grep epel-release epel-release.noarch 7-9 extras [root@bogon yum.repos.d]# yum install -y epel-release Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com 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 #多了epel.repo和epel-testing.repo CentOS-Base.repo epel.repo epel-testing.repo repo_bak
5、再次运行yum clean all 清除缓存，运行 yum makecache 生成新的缓存
6、查看启用的yum源和所有的yum源
[root@bogon yum.repos.d]# yum repolist enabled #查看启用的仓库 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * epel: mirrors.ustc.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com repo id repo name status base/7/x86_64 CentOS-7 - Base - mirrors.aliyun.com 9,591 epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 12,277 extras/7/x86_64 CentOS-7 - Extras - mirrors.aliyun.com 388 updates/7/x86_64 CentOS-7 - Updates - mirrors.aliyun.com 1,929 repolist: 24,185 [root@bogon yum.repos.d]# yum repolist all #查看所有的仓库 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * epel: mirrors.ustc.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com repo id repo name status base/7/x86_64 CentOS-7 - Base - mirrors.aliyun.com enabled: 9,591 centosplus/7/x86_64 CentOS-7 - Plus - mirrors.aliyun.com disabled contrib/7/x86_64 CentOS-7 - Contrib - mirrors.aliyun.com disabled epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 enabled: 12,277 epel-debuginfo/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 - Debug disabled epel-source/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 - Source disabled epel-testing/x86_64 Extra Packages for Enterprise Linux 7 - Testing - x86_64 disabled epel-testing-debuginfo/x86_64 Extra Packages for Enterprise Linux 7 - Testing - x86_64 - Debug disabled epel-testing-source/x86_64 Extra Packages for Enterprise Linux 7 - Testing - x86_64 - Source disabled extras/7/x86_64 CentOS-7 - Extras - mirrors.aliyun.com enabled: 388 updates/7/x86_64 CentOS-7 - Updates - mirrors.aliyun.com enabled: 1,929 repolist: 24,185
