Chapter 6. Disconnected installation

Procedure

1. Attach the BaseOS and AppStream required repositories:

   # subscription-manager repos \
       --enable rhel-9-for-x86_64-baseos-rpms \
       --enable rhel-9-for-x86_64-appstream-rpms

2. Perform the reposync:

   # dnf install yum-utils
   # reposync -m --download-metadata --gpgcheck \
       -p /path/to/download

   1. Use reposync with --download-metadata and without --newest-only. See RHEL 8 Reposync.

      • If you are not using --newest-only, the repos downloaded may take an extended amount of time to sync due to the large number of GB.
      • If you are using --newest-only, the repos downloaded may take an extended amount of time to sync due to the large number of GB.

   After the reposync is completed, your repositories are ready to use with a web server.

3. Move the repositories to your disconnected network.

Procedure

1. Install prerequisites:

   $ sudo dnf install httpd

2. Configure httpd to serve the repo directory:

   /etc/httpd/conf.d/repository.conf
   
   DocumentRoot '/path/to/repos'
   
   <LocationMatch "^/+$">
       Options -Indexes
       ErrorDocument 403 /.noindex.html
   </LocationMatch>
   
   <Directory '/path/to/repos'>
       Options All Indexes FollowSymLinks
       AllowOverride None
       Require all granted
   </Directory>

3. Ensure that the directory is readable by an apache user:

   $ sudo chown -R apache /path/to/repos

4. Configure SELinux:

   $ sudo semanage fcontext -a -t httpd_sys_content_t "/path/to/repos(/.*)?"
   $ sudo restorecon -ir /path/to/repos

5. Enable httpd:

   $ sudo systemctl enable --now httpd.service

6. Open firewall:

   $ sudo firewall-cmd --zone=public --add-service=http –add-service=https --permanent
   $ sudo firewall-cmd --reload

7. On automation services, add a repo file at /etc/yum.repos.d/local.repo, and add the optional repos if needed:

   [Local-BaseOS]
   name=Local BaseOS
   baseurl=http://<webserver_fqdn>/rhel-8-for-x86_64-baseos-rpms
   enabled=1
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
   
   [Local-AppStream]
   name=Local AppStream
   baseurl=http://<webserver_fqdn>/rhel-8-for-x86_64-appstream-rpms
   enabled=1
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

Procedure

1. Mount DVD or ISO:

   1. DVD

      # mkdir /media/rheldvd && mount /dev/sr0 /media/rheldvd

   2. ISO

      # mkdir /media/rheldvd && mount -o loop rhrhel-8.6-x86_64-dvd.iso /media/rheldvd

2. Create yum repo file at /etc/yum.repos.d/dvd.repo

   [dvd-BaseOS]
   name=DVD for RHEL - BaseOS
   baseurl=file:///media/rheldvd/BaseOS
   enabled=1
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
   
   [dvd-AppStream]
   name=DVD for RHEL - AppStream
   baseurl=file:///media/rheldvd/AppStream
   enabled=1
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

3. Import the gpg key:

   # rpm --import /media/rheldvd/RPM-GPG-KEY-redhat-release

   Note

   If the key is not imported you will see an error similar to

   # Curl error (6): Couldn't resolve host name for
   https://www.redhat.com/security/data/fd431d51.txt [Could not resolve host:
   www.redhat.com]
