CentOS Linux will stop maintenance. I suggest you switch to Anolis or Alinux

Notice: The CentOS 8 operating system version has reached the end of its lifecycle (EOL), and the Linux community is no longer maintaining this operating system version. I suggest you switch to Anolis or Alinux. If your business still needs to use some installation packages from the CentOS 8 system during the transition period, please switch the CentOS 8 source according to the following text.

1. 备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2. 下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/

CentOS 8 (CentOS 8 official source has been taken offline, it is recommended to switch to CentOS Vault source)

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

or

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo

or

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo

CentOS 7

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

or

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

3. Run yum makecache to generate cache

4. Other

Non Alibaba Cloud ECS users will receive the message 'Could't resolve host' mirrors. cloud. aliyuncs. com ', which does not affect usage. Users can also modify the relevant configurations themselves: eg:

sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
