为CentOS安装yum源 使用centos-vault作为停止支持的CentOS的yum源
2021-06-07

安装CentOS 6.10 版本后发现，无法使用yum安装软件

登录官方网站，看到下载界面里边已经取消了CentOS6的下载链接，我想可能是已经不再支持了。
当我使用最小安装完毕的CentOS 6.10进行yum安装软件时，会报下边的错误。
 
[root@localhost ~]# yum install vim -y
Loaded plugins: fastestmirror
Setting up Install Process
Determining fastest mirrors
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. Invalid release/repo/arch combination/
removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base
 
解决：
 我去网上查了一下上边的错误，原因是：更新的repo源里边的地址错误，随后我换成了阿里源云，网易云，都不得行，我手动去登录里边的网址，结果显示已经下架。我就用到了官方的已经下架系统的镜像网站


将 /etc/yum.repos.d/CentOS-Base.repo 文件中所有的源主机地址修改为http://vault.centos.org，并且将$releasever替换为当前系统所使用的CentOS版本，可以使用6.x最后的版本6.10。注意，需要将所有其他备用的主机都删除，内容如下：
 vi /etc/yum.repos.d/CentOS-Base.repo

 确认在 /etc/yum.repos.d/目录没有除了CentOS-Base.repo之外其他以repo结尾的文件，如果有的话需要删除，然后执行 yum clean all && yum makecache 更新和启用新的yum源。
