使用 Centos 6 时，我无法再运行"yum update"，我收到此错误"找不到 repo： base 的有效 baseurl"

Question

当使用带有Centos6映像的VirtualBox时，我不能再做yum更新了，我已经在互联网上检查过了，看起来Centos6已被弃用。

[root@centos69 ~]# yum makecache

Answer 1

解决这个问题有两种可能的方法:

1. 编辑CentOS-Base。repo文件与vim

vim /etc/yum.repos.d/CentOS-Base.repo

删除或注释所有以'mirrorlist'开头的行。

并将以下行添加到文件的每个[节]中，如[base]， [updates]…

baseurl=https://vault.centos.org/6.10/os/$basearch/

2. 另一个解决方案是在来自此repo https://vault.centos.org/
的映像上运行此命令

/scripts/autorepair centos6_base_repo_is_no_more

是的，就像红帽子6。x centos 6确实在2020年11月上线了，希望你的虚拟机里没有任何敏感的东西。https://forums.centos.org/viewtopic.php?t=72710

您可以在vault.centos.org更改为使用保险库。首先，您应该禁用任何不再工作的repo。您可以使用

获取repos列表

yum repolist

则可以使用

禁用它们

yum-config-manager --disable  {reponame} {reponame}

yum-config-manager --disable  base update

或者全部禁用

yum-config-manager |grep ^\[|tr -d ']['|xargs yum-config-manager --disable

一旦坏的repo被禁用，你需要添加vault repo。

yum-config-manager --add-repo=https://vault.centos.org/6.10/os/x86_64/

之后，你可以根据需要安装软件包，但请记住-它没有任何更新，所以如果安全问题，你需要将操作系统更改为支持的更新版本。

遵循这个帖子，它工作。https://www.getpagespeed.com/server-setup/how-to-fix-yum-after-centos-6-went-eol文章中的替代方法:

vi /etc/yum.repos.d/CentOS-Base.repo

并将内容替换为:
