错误：无法为 repo 找到有效的 baseurl：centos-sclo-rh

Question

当尝试yum update在 Centos6上使用时，我收到此错误：“错误：找不到 repo 的有效 baseurl：centos-sclo-rh。” 有什么办法可以摆脱这种错误状态吗？

Answer 1

你可以试试这个。

echo "https://vault.centos.org/6.10/os/x86_64/" > /var/cache/yum/x86_64/6/base/mirrorlist.txt
echo "http://vault.centos.org/6.10/extras/x86_64/" > /var/cache/yum/x86_64/6/extras/mirrorlist.txt
echo "http://vault.centos.org/6.10/updates/x86_64/" > /var/cache/yum/x86_64/6/updates/mirrorlist.txt
echo "http://vault.centos.org/6.10/sclo/x86_64/rh" > /var/cache/yum/x86_64/6/centos-sclo-rh/mirrorlist.txt
echo "http://vault.centos.org/6.10/sclo/x86_64/sclo" > /var/cache/yum/x86_64/6/centos-sclo-sclo/mirrorlist.txt

Answer 2

因为 centos6 已经 EOL，对于 centos-sclo-rh ，将以下内容添加到 CentOS-Base.repo

[centos-sclo-rh]
name=CentOS-6.10 - SCLo rh
baseurl=http://vault.centos.org/centos/6.10/sclo/$basearch/rh/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

[centos-sclo-sclo]
name=CentOS-6.10 - SCLo sclo
baseurl=http://vault.centos.org/centos/6.10/sclo/$basearch/sclo/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

由于我们谈论的是已达到 EOL 的 CentOS6，这是意料之中的事情。如果您不想担心使用yum clean all，请导航到 /etc/yum.repos.d/ 并调整 CentOS-Base.repo 中的条目。

您需要注释掉所有以“ mirrorlist= ”开头的行，并取消对以“ baseurl= ”开头的行的注释。

接下来是在“ baseurl ”行上编辑网址- 将所有“ mirror.centos.org ”条目切换为“ vault.centos.org ”。例如，编辑后的第一个块应如下所示：

[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
baseurl=http://vault.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
