centos使用scl切换软件版本时提示Cannot find a valid baseurl for repo: centos-sclo-rh/x86_64 

问题原因

CentOS7的SCL源在2024年6月30日停止维护了。 当scl源里面默认使用了centos官方的地址,无法连接,需要替换为阿里云。

解决办法

1、
重命名原来的文件:

cd /etc/yum.repos.d/
mv CentOS-SCLo-scl.repo CentOS-SCLo-scl.repo.bak
mv CentOS-SCLo-scl-rh.repo CentOS-SCLo-scl-rh.repo.bak

vim CentOS-SCLo-scl-rh.repo
粘贴以下内容:

[centos-sclo-rh]
name=CentOS-7 - SCLo rh
baseurl=https://mirrors.aliyun.com/centos/7/sclo/x86_64/rh/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid> 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: centos-sclo-rh/x86_64
