1、yum源失效,參考資料https://www.cnblogs.com/zyjfire/p/7279487.html
上程式碼: #1、檢視CentOs版本; [root@localhost /]# lsb_release -a LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release6.9 (Final) Release: 6.9 Codename: Final
版本為6.9
這裡採用參考資料的第二種方式更換yum源
#2、進入yum配置檔案目錄;
[root@localhost /]# cd /etc/yum.repos.d/
#3、備份原檔案;
[root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
#4、下載163配置檔案;
[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
#5、修改名稱;
[root@localhost yum.repos.d]# mv CentOS6-Base-163.repo CentOS-Base.repo
#6、手動修改baseurl和gpgkey;
baseurl:將http://mirrors.163.com/centos/$releasever替換為http://vault.centos.org/6.9
gpgkey:將http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6替換為http://vault.centos.org/RPM-GPG-KEY-CentOS-6
注:版本號根據自己的CentOs版本而定,可訪問替換地址檢視yum原始檔是否存在。
附163檔案和改後配置檔案:
