# yum install yum-utils createrepo

This may install some additional packages to support other repositories, depending on what repositories you already had enabled before you started the process. Let's take a look at the contents of the "/etc/yum.repos.d" directory now.

Repository Creation

Install the following packages, which include the utilities necessary to set up the repository.

# yum install yum-utils createrepo

Create the following directories to hold the main OS and UEK respoitories.

# mkdir -p /u01/repo/OracleLinux

# mkdir -p /u01/repo/logs

# mkdir -p /u01/repo/scripts

If you've done a default installation of Oracle Linux 8, the "ol8_baseos_latest" and "ol8_UEKR6" repositories should already be enabled in the "/etc/yum.repos.d/public-yum-ol8.repo" file, but it's worth checking before you continue.

The reposync command is used to synchronize a remote yum repository to a local directory, using yum to retrieve the packages.

#/usr/bin/reposync --newest-only --repoid=ol8_baseos_latest -p /u01/repo/OracleLinux

# /usr/bin/reposync --newest-only --repoid=ol8_UEKR6 -p /u01/repo/OracleLinux

# /usr/bin/reposync --newest-only --repoid=ol8_appstream -p /u01/repo/OracleLinux

# /usr/bin/reposync --newest-only --repoid=ol8_spacewalk210_client --repoid=ol8_gluster_appstream -p /u01/repo/OracleLinux

# /usr/bin/reposync --newest-only --repoid=ol8_developer -p /u01/repo/OracleLinux

# /usr/bin/reposync --newest-only --repoid=ol8_addons -p /u01/repo/OracleLinux

It takes a long time to sync the repositories the first time, so be patient. I waited overnight for the 32G of downloads to complete. Subsequent refreshes only bring across the changed packages, so they are much quicker. The "newest-only" option reduces the total size of the download.

Once complete, you can create the repositories from the local directories using the createrepo command.

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_baseos_latest/getPackage

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_appstream/getPackage

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_developer/getPackage

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_gluster_appstream/getPackage

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_addons/getPackage

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_developer_EPEL/getPackage

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_spacewalk210_client/getPackage

# /usr/bin/createrepo /u01/repo/OracleLinux/ol8_UEKR6/getPackage

Resync the Repository

A resync of the Yum repositories involves repeating the reposync and createrepo commands, so you should script them and run them from CRON. Create a script called "/u01/repo/scripts/repo_sync.sh" with the following contents.

#!/bin/bash

## Download Latest Repo (RPM's) from OEL Repository 8 (OEL 8)

LOG_FILE=/u01/repo/logs/repo_sync_$(date +%Y.%m.%d).log

# Remove old logs

find /u01/repo/logs/repo_sync* -mtime +5 -delete; >> $LOG_FILE 2>&1

# Sync repositories

/usr/bin/reposync --newest-only --repoid=ol8_baseos_latest -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/reposync --newest-only --repoid=ol8_developer -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/reposync --newest-only --repoid=ol8_developer_EPEL -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/reposync --newest-only --repoid=ol8_spacewalk210_client -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/reposync --newest-only --repoid=ol8_UEKR6 -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/reposync --newest-only --repoid=ol8_appstream -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/reposync --newest-only --repoid=ol8_gluster_appstream -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/reposync --newest-only --repoid=ol8_addons -p /u01/repo/OracleLinux >> $LOG_FILE 2>&1

/usr/bin/createrepo /u01/repo/OracleLinux/ol8_baseos_latest/getPackage/ >> $LOG_FILE 2>&1

/usr/bin/createrepo /u01/repo/OracleLinux/ol8_developer4/getPackage/ >> $LOG_FILE 2>&1

/usr/bin/createrepo /u01/repo/OracleLinux/ol8_developer_EPEL/getPackage/ >> $LOG_FILE 2>&1

/usr/bin/createrepo /u01/repo/OracleLinux/ol8_spacewalk210_client/getPackage/ >> $LOG_FILE 2>&1

/usr/bin/createrepo /u01/repo/OracleLinux/ol8_UEKR6/getPackage/ >> $LOG_FILE 2>&1

/usr/bin/createrepo /u01/repo/OracleLinux/ol8_gluster_appstream/getPackage/ >> $LOG_FILE 2>&1

/usr/bin/createrepo /u01/repo/OracleLinux/ol8_addons/getPackage/ >> $LOG_FILE 2>&1

Make the file executable.

# chmod u+x /u01/repo/scripts/repo_sync.sh

Set up a CRON job to run the script on a daily basis. The following entry runs the script each day at 01:00.

0 1 * * * /u01/repo/scripts/repo_sync.sh > /dev/null 2>&1

Setup the HTTP Server

Install the Apache HTTP servers, start it and make sure it restarts automatically on reboot.

# yum install httpd

# systemctl start httpd

# systemctl enable httpd

If you are using the Linux firewall you will need to punch a hole for port 80.

# firewall-cmd --permanent --zone=public --add-port=80/tcp

# firewall-cmd --reload

Either set SELinux to permissive, or configure the fcontext for the repository files as shown below.

# # One-off configuration.

# yum install policycoreutils-python -y

# semanage fcontext -a -t httpd_sys_content_t "/u01/repo/OracleLinux(/.*)?"

# # Run each time the repo contents change.

# restorecon -F -R -v /u01/repo/OracleLinux

Present the repositories using the HTTP server.

# mkdir -p /var/www/html/repo/OracleLinux/ol8_latest

# mkdir -p /var/www/html/repo/OracleLinux/ol8_developer

# mkdir -p /var/www/html/repo/OracleLinux/ol8_developer_EPEL

Point Servers to the Local Repository

To allow a server to use the local Yum repositories, create a file called "/etc/yum.repos.d/local-ol8.repo" with the following contents, where "ol8-yum.localdomain" is the name of the server with the Yum repositories.

[local_ol8_baseos_latest]

name=Oracle Linux $releasever Latest ($basearch)

baseurl=http://ol8-yum.localdomain/repo/OracleLinux/ol8_latest/$basearch/
