Chapter 15. Creating a remote repository

Follow the steps in this procedure to create an installation source for a network-based installation using a remote repository containing extracted contents of the Binary DVD ISO image. The installation source is accessed over HTTP or HTTPS.

Prerequisites

  • A Red Hat Enterprise Linux 8 installation DVD/ISO image
  • Several servers running Red Hat Enterprise Linux

15.1. Installing Apache on RHEL

This procedure will help you install Apache on Red Hat Enterprise Linux 8.

Prerequisites

  • Access to a repo with Apache webserver

Procedure

  1. Install the httpd package 

    # yum install httpd

  2. Run, then enable the Apache webserver. These commands will also start the webserver after reboot. 

    # systemctl enable httpd
# systemctl start httpd

  3. Insert any website files you may have. 

    # echo Apache on RHEL 8 > /var/www/html/index.html

  4. Update the firewall. 

    # firewall-cmd --add-service=http --permanent
# firewall-cmd --add-service=http

  5. Access the website. 

    http://<the-apache-ip-address>

http://<the-apache-hostname>

15.2. Creating a remote repository

Multiple Red Hat Enterprise Linux servers may access a single Red Hat Enterprise Linux repository on the network. This requires a running web server, most likely this will be Apache.

Prerequisites

  • A Red Hat Enterprise Linux 8 installation DVD
  • Several servers running Red Hat Enterprise Linux

Procedure

  1. Mount and copy the content of downloaded DVD. 

    mkdir /mnt/rhel8
mount -o loop,ro rhel-8.1-x86_64-dvd.iso /mnt/rhel8/
cp -r /mnt/rhel8/ /var/www/html/
umount  /mnt/rhel8

    The next step is performed on the client side, not on the server where Apache is installed.

  2. Create a repo file for both BaseOS and AppStream repositories. 

    vi /etc/yum.repos.d/rhel_http_repo.repo

[BaseOS_repo_http]
name=RHEL_8.0_x86_64_HTTP BaseOS
baseurl="http://myhost/rhel8/BaseOS"
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[AppStream_repo_http]
name=RHEL_8.0_x86_64_HTTP AppStream
baseurl="http://myhost/rhel8/AppStream"
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
