How to mirror or copy a repository in Red Hat Enterprise Linux 9
To create a local mirror repo of the latest update for Red Hat Enterprise Linux 9 without using the Satellite server. The main purpose is to create local mirror repo for use to provide packages for the hosts on your LAN that are not connected to the internet, and therefore cannot access the upstream repos directly.
Setting up mirrored repos for Red Hat Enterprise Linux 9
To start, you’ll need to choose the web server that will serve the mirrored repos to your LAN. Then, if you’re using Red Hat Enterprise Linux 9, then to create a basic repo you have to start by installing createrepo_c. Don’t worry, this tool is included in your subscription, too. Install it on your web server with the following:
sudo dnf install createrepo_c
Next, you need the repository ID for the repo you would like to sync. Run yum repolist, and you’ll find the repo ID in the output’s first column:
[root@localhost ~]# subscription-manager repos --list
+----------------------------------------------------------+
Available Repositories in /etc/yum.repos.d/redhat.repo
+----------------------------------------------------------+
Repo ID: rhel-9-for-x86_64-appstream-rpms
Repo Name: Red Hat Enterprise Linux 9 for x86_64 - AppStream (RPMs)
Repo URL: https://cdn.redhat.com/content/dist/rhel9/$releasever/x86_64/appstream/os
Enabled: 1
Repo ID: rhel-9-for-x86_64-baseos-rpms
Repo Name: Red Hat Enterprise Linux 9 for x86_64 - BaseOS (RPMs)
Repo URL: https://cdn.redhat.com/content/dist/rhel9/$releasever/x86_64/baseos/os
Enabled: 1
Repo ID: rhel-9-for-x86_64-baseos-source-rpms
Repo Name: Red Hat Enterprise Linux 9 for x86_64 - BaseOS (Source RPMs)
Repo URL: https://cdn.redhat.com/content/dist/rhel9/$releasever/x86_64/baseos/source/SRPMS
Enabled: 0
For example, to sync the packages from the "rhel-9-for-x86_64-appstream-rpms" repo and create a basic local repository, execute the following commands:
For example, Basic local repository Location is /var/www/repo :
For Red Hat Enterprise Linux 9, this process is even easier. You only need the reposync command:
Basic syntax of reposync for Red Hat Enterprise Linux 9 :
reposync -p <-download-path-> --download-metadata --repo=<-repo id->
reposync -p /var/www/repo --download-metadata --repo=rhel-9-for-x86_64-appstream-rpms
Final Repo Location Will be /var/www/repo/rhel-9-for-x86_64-appstream-rpms
Sharing the local repository to Your Local Network
Once the packages are fetched and the local repo is created using either of these methods, the local repository can be distributed among the offline/disconnected systems using a simple web server, FTP, or NFS. The following knowledgebase articles provide the necessary information regarding your choice of distribution:
- Apache (HTTP)
- Apache (HTTPS)
- FTP
- NFS share
Create Repo File in ‘/etc/yum.repos.d/’ Directory
Create a repo file with name "rhel9-local.repo" under the folder /etc/yum.repos.d/ with following content
Create a repo file with name "rhel9-local.repo" under the folder /etc/yum.repos.d/ with following content
sudo vi /etc/yum.repos.d/rhel9-local.repo
Following Repo content
Basic syntax of repo for Red Hat Enterprise Linux 9 :
[<-repo-id->] baseurl=https://ServerHostname/<-repo-id->/ enabled=1
Basic syntax of repo for Red Hat Enterprise Linux 9. In my case host name is linuxits.com :
[rhel-9-for-x86_64-appstream-rpms] baseurl=https://linuxits.com/rhel-9-for-x86_64-appstream-rpms/ enabled=1
Finnaly Save and close the file.
To Verify Repo content File output will be
cat /etc/yum.repos.d/rhel9-local.repo
[rhel-9-for-x86_64-appstream-rpms] baseurl=https://linuxits.com/rhel-9-for-x86_64-appstream-rpms/ enabled=1
Flush Yum/DNF & Subscription Manager Cache
Execute following commands to clean yum or dnf and subscription manager cache.:
sudo dnf clean all sudo subscription-manager clean
To Disable Red Hat subscription manager warning message
In the above output, we are getting a warning message ‘This system is not registered with an entitlement’. So, if you want to disable this warning message, edit the file ‘/etc/yum/pluginconf.d/subscription-manager.conf’ , change the parameter ‘enabled=1’ to ‘enabled=0’.
sudo vi /etc/yum/pluginconf.d/subscription-manager.conf
Save and exit the file.
For Test Install any rpm Packages using Local Repository
Now we are all set to test our local repository. Run beneath command to view configure repository.
sudo dnf repolist
Now, You can Install packages using yum/dnf command via above configure local repository.
sudo dnf install httpd
Output,
