CentOS 8 ends life cycle, switch to CentOS

I just shared two alternative versions of the CentOS system a few days ago. Unexpectedly, I received a text message from Alibaba Cloud today, informing me that CentOS 8 has ended its life cycle, and it is recommended to switch to the CentOS-Vault source as soon as possible. The CentOS system installed on the Bricklayer VPS should be the same, so here I will share the method of switching to the CentOS Vault source.

Configuring CentOS-Vault source tutorial

The following is the text message:

The CentOS 8 operating system version has ended its life cycle, and the Alibaba Cloud mirror station has also removed the corresponding mirror source. If your business still needs to use some installation packages in CentOS 8 during the transition period, it is recommended to switch to the CentOS-Vault source. For specific configuration, please click here.

Notice: The CentOS 8 operating system version has reached end of life (EOL), and the Linux community no longer maintains this operating system version. It is recommended that you switch to Anolis or Alinux. If your business still needs to use some installation packages in the CentOS 8 system during the transition period, please switch the source of CentOS 8 as follows.

1. Backup

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

2. Download the new CentOS-Base.repo to /etc/yum.repos.d/

CentOS 8 (CentOS 8 official source has been 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 (CentOS 6 official source is 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-6.10.repo

or

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-6.10.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. Others

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

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

How to switch sources after CentOS 8 ends its life cycle

Use the following command:

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
yum clean all && yum makecache

At present, I see some comments under the official documentation page that may point out that there may be some actual problems. It is recommended that if you encounter problems, you can refer to the comments below the official documentation to solve them.

Select a suggestion:

• Getting started: Los Angeles CN2 package, currently the cheapest, optional CN2 GT computer room, the entry-level choice.
• Recommendation:Los Angeles CN2 GIA-E package, super fast, with many optional computer rooms (DC6, DC9, Japan Softbank, Netherlands Unicom, etc.), the most cost-effective.
• High-end: Hong Kong CN2 GIA package, the price is higher, but impeccable. The Tokyo CN2 GIA package is also a very good high-end option.
