[转]CentOS7配置阿里云yum源和EPEL源

配置阿里云yum源(参考:http://mirrors.aliyun.com/help/centos)

1、备份

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

2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/

复制代码

[[email protected] 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

2018-02-09 16:33:47 (182 MB/s) – ‘/etc/yum.repos.d/CentOS-Base.repo’ saved [2573/2573]

[[email protected] yum.repos.d]# ls
CentOS-Base.repo repo_bak

复制代码

3、之后运行yum clean all 清除缓存,运行 yum makecache 生成新的缓存
复制代码

[[email protected] 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
[[email protected] 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

复制代码

安装EPEL(Extra Packages for Enterprise Linux )源

4、安装EPEL源
复制代码

[[email protected] yum.repos.d]# yum list | grep epel-release
epel-release.noarch 7-9 extras
[[email protected] yum.repos.d]# yum install -y epel-release
Loaded plugins: fastestmirror

[[email protected] yum.repos.d]# ls #多了epel.repo和epel-testing.repo
CentOS-Base.repo epel.repo epel-testing.repo repo_bak

复制代码

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
复制代码

[[email protected] yum.repos.d]# yum repolist enabled #查看启用的仓库
