centos 7.4 配置阿里YUM源鏡像

環境：centos 7.4

只搭建阿里源

步驟一：安裝wget，已安裝則跳過此步驟

[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
-bash: wget: 未找到命令
[root@localhost yum.repos.d]# yum -y install wget

 

步驟二：移除舊YUM源

[root@localhost ~]# mkdir -p /etc/yum.repos.d/bak && mv /etc/yum.repos.d/* /etc/yum.repos.d/bak
mv: 無法將目錄"/etc/yum.repos.d/bak" 移動至自身的子目錄"/etc/yum.repos.d/bak/bak" 下

 

步驟三：下載阿里源配置

[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@localhost ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

 

步驟四：清楚緩存，查看YUM源

[root@localhost ~]# yum clean all
[root@localhost ~]# yum repolist
