URL Repo CentOS 7 Setelah EOL 30 Juni 2024, Kali ini kami mendapatkan kendala pada server setelah CentOS 7 habis masa pakainya di tanggal 30 Juni 2024, ketika ingin melakukan instalasi update package maka akan muncul error yang memberitahukan repo sudah tidak ada, dikarenakan mirror repo sudah di hapus dari server repository yang terdaftar di server CentOS 7 yang digunakan. Untuk itu, wajib bagi yang masih menggunakan CentOS 7 beralih ke Upgrade CentOS ke versi terbaru atau beralih ke Distro Rocky Linux Atau AlmaLinux. Untuk yang masih bertahan menggunakan CentOS 7 bisa dialihkan mirror repo yang masih active dan bisa digunakan. Berikut langkah-langkah untuk merubah:

Jika sudah sukses update, coba reboot server kamu , agar kernel terbaru bisa digunakan.

Jika mencoba yum update dan didapat error seperti berikut ini

[root@xxx ~]# yum update
Loaded plugins: fastestmirror
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
Repository fasttrack is listed more than once in the configuration
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"

One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. 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: base/7/x86_64

maka kamu harus disable repo existing dengan cara :

yum --disablerepo=CentOS-Base.repo

ATAU memindahkan repo yang bermasalah ke folder lain.

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