今天扣丁學(xué)堂Linux培訓(xùn)老師給大家介紹一下關(guān)于CentOS7配置阿里云yum源方法代碼詳解，下面我們一起來(lái)看一下吧。


打開(kāi)centos的yum文件夾

輸入命令cd/etc/yum.repos.d/

用wget下載repo文件

輸入命令wget  http://mirrors.aliyun.com/repo/Centos-7.repo

如果wget命令不生效，說(shuō)明還沒(méi)有安裝wget工具，輸入yum-yinstallwget回車(chē)進(jìn)行安裝。

當(dāng)前目錄是/etc/yum.repos.d/，剛剛下載的Centos-7.repo也在這個(gè)目錄上

備份

[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

repo_bak

下載新的CentOS-Base.repo到/etc/yum.repos.d/

wget -O /etc/yum.repos.d/CentOS-Base.repo

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

[root@bogon yum.repos.d]# ls
CentOS-Base.repo repo_bak

之后運(yùn)行yumcleanall清除緩存，運(yùn)行yummakecache生成新的緩存

[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
