YUM repository Configuration RHEL 8 | Arkit

Yellowdog Updater, Modified (YUM) configuration in RHEL 8. Red Hat Enterprise Linux Version 8 includes AppStream as a new repository so YUM configuration is little different than actual. Let’s see How to configure RHEL 8 YUM Repository step by step. YUM repository RHEL 8

Mount RHEL 8 Installation Media

By default installation media will get AppStream and BaseOS packages. First mount the DVD media into RHEL 8 server using below command (Assuming your CD/DVD drive /dev/sr0). You must have sudo privileges or become root user to mount.

# mount /dev/sr0 /mnt

Create new directory in where ever you want to dump entire RPM packages Example: /repo

# mkdir /repo

copy the content using below command

# cp -Rv /mnt/BaseOS/ /repo/
# cp -Rv /mnt/AppStream /repo/

Now check /repo directory

[root@rhel8-server1 repo]# ls -ltr
total 0
dr-xr-xr-x. 4 root root 38 Jul 24 01:47 BaseOS
dr-xr-xr-x. 4 root root 38 Jul 24 01:48 AppStream

RHEL 8 YUM Repository configuration

Switch directory to /etc/yum.repos.d/ and create .repo files

[root@rhel8-server1 yum.repos.d]# cat BaseOS.repo
[BaseOSRepo]
name=BaseOS
baseurl=file:///repo/BaseOS/
enabled=1
gpgcheck=0

[root@rhel8-server1 yum.repos.d]# cat AppStream.repo
[AppStreamRepo]
name=AppStream
baseurl=file:///repo/AppStream/
enabled=1
gpgcheck=0
