測試環境為 CentOS 8 x86_64 (虛擬機)
目前正在使用的 CentOS Linux 8 End Of Life (EOL) 為 December 31st, 2021,想要繼續更新 CentOS8 方式有 2 種.
[root@localhost ~]# yum update CentOS-8 - AppStream 70 B/s | 38 B 00:00 Error: Failed to download metadata for repo 'AppStream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
CentOS repo
主要是修改 Repo 的地方到 vault.centos.org
[root@localhost ~]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-* [root@localhost yum.repos.d]# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
這樣就可以繼續更新了,但這個也沒再更新了,只是不會出現錯誤,建議使用下面方式改成 CentOS Stream 版本.
[root@localhost yum.repos.d]# yum update -y
CentOS Stream
原先 CentOS 是 RHEL 釋出後的開源版本
Fedora -> RHEL -> CentOS
但如今規則改變了 CentOS Stream 成為 RHEL 釋出前的開源版本.
Fedora -> CentOS Stream -> RHEL
[root@localhost ~]# dnf install centos-release-stream -y --allowerasing [root@localhost ~]# dnf distro-sync -y
或是
[root@localhost ~]# dnf --disablerepo '*' --enablerepo extras swap centos-linux-repos centos-stream-repos [root@localhost ~]# dnf distro-sync -y
已經變成 CentOS Stream 版本了.
[root@localhost ~]# more /etc/redhat-release CentOS Stream release 8
