How to create local yum repository with DVD iso

We will create local yum repository with DVD iso on RHEL | Centos for systems where internet is not available.

Download RHEL/Centos ISO

For downloading RHEL ISO please access Red Hat official download page. For downloading CentOS refer

Once ISO is downloaded, upload it to the server where you want to create the local repository.

[root@master2 ~]$ ls -ltrh
total 9.9G
-rwxrwxrwx 1 nobody kvm 4.4G Feb  5 08:52  CentOS-7-x86_64-DVD-2009.iso
-rw-r--r-- 1 ved    ved 4.3G Mar  9 14:57  rhel-server-7.9-x86_64-dvd.iso

Mount ISO File on Linux

Create the mount point directory on Linux

[root@master2 ~]$ sudo mkdir /mnt/ISO

Mount the ISO file on Linux

[root@master2 ~]$ sudo mount -o loop rhel-server-7.9-x86_64-dvd.iso /mnt/ISO/
mount: /dev/loop0 is write-protected, mounting read-only

Once dvd is mounted, goto the /mnt/ISO and list the files in the ISO directory

[root@master2 ~]# cd /mnt/ISO/
[root@master2 ISO]# ls
addons  EULA              GPL     isolinux  media.repo  repodata                 RPM-GPG-KEY-redhat-release
EFI     extra_files.json  images  LiveOS    Packages    RPM-GPG-KEY-redhat-beta  TRANS.TBL

We can copy the content of /mnt/ISO on some local directory or we can use same directory for creating the local yum repository.

Create local yum repository with DVD iso

We will now create the yum configuration file for our yum repository using vim inside /etc/yum.repos.d/ directory

[root@master2 ISO]# vim /etc/yum.repos.d/rhel-local.repo

[RHEL-7.9-Local-Repo]
name = RHEL 7.9 Local Repository
baseurl = file:///mnt/ISO  
# Replace /mnt/ISO if you have copied the ISO directory content to some other directory
gpgcheck = 0
enabled = 1

Verify the newly created Repository

[root@master2 ISO]# yum repolist
