一、Centos7的base源配置阿里云的yum源：
1、备份旧的yum源目录下的所有文件
[root@ELK-chaofeng07 yum.repos.d]# mkdir ../yum.repos.d.bak ; mv ./* ../yum.repos.d.bak
2、下载base文件
#各系统版本repo文件对应的下载操作
CentOS
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3、清空缓存
yum clean all
4、构建新的缓存
yum makecache
5、查看基本yum源
[root@ELK-chaofeng07 yum.repos.d]# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* epel: mirrors.tuna.tsinghua.edu.cn
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
repo id repo name status
base//x86_64 CentOS- - Base - mirrors.aliyun.com ,
*epel/x86_64 Extra Packages for Enterprise Linux - x86_64 ,
extras//x86_64 CentOS- - Extras - mirrors.aliyun.com
updates//x86_64 CentOS- - Updates - mirrors.aliyun.com ,
repolist: ,
二、配置阿里云的epel源
1、下载阿里云的epel源。我们到官网：http://mirrors.aliyun.com
2、开始备份旧的epel-release源
mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup
3、下载新的阿里云的epel源
epel(RHEL )
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
epel(RHEL )
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
epel(RHEL )
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-5.repo
4、清空缓存
[root@ELK-chaofeng07 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
4、构建新的缓存
[root@ELK-chaofeng07 yum.repos.d]# yum makecache
