Introduction

Oracle Linux yum server hosts software for Oracle Linux and compatible distributions. These instructions help you get started configuring your Linux system for Oracle Linux yum server and installing software via yum or dnf

Configuring Your System to Install Software from Oracle Linux Yum Server

If you are starting from scratch, and don’t have a Linux OS installed, download and install Oracle Linux. Alternatively, use an Oracle Linux Vagrant box to run with Oracle VM VirtualBox or KVM

Oracle Linux

In most cases, your Oracle Linux system will already be set up to install software from Oracle Linux yum server. See Installing Software from Oracle Linux Yum Server for an overview software available on this yum server.

Oracle Linux 8 and 9: About DNF and Application Stream

The yum utility that is provided with Oracle Linux 8 and 9 is based on Dandified Yum (DNF). You can use dnf to install or upgrade RPM packages, while automatically handling package dependencies and requirements. The yum command that is provided with Oracle Linux 8 and 9 is a symbolic link to dnf and you can use the dnf command and all of its options similarly to how you used the yum command on previous releases of Oracle Linux.

DNF introduces the concepts of modules, streams and profiles to allow for the management of different versions of software applications within a single operating system release. To read more about this subject, see the documentation: Oracle® Linux: Managing Software in Oracle Linux

To install software from Oracle Linux yum server on Red Hat Enterpise Linux perform these actions:

Red Hat Enterprise Linux 7

1. Import the Oracle Linux GPG key using these instructions.

2. Ceate a temporary yum repository configuration file /etc/yum.repos.d/ol7-temp.repo with the following as the minimum required content:

[ol7_latest]
name=Oracle Linux $releasever Latest ($basearch)
baseurl=https://yum.oracle.com/repo/OracleLinux/OL7/latest/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

3. Install oraclelinux-release-el7:

# yum install oraclelinux-release-el7

4. Remove ol7-temp.repo and any other remaining repo files that may conflict with Oracle Linux yum server:

# mv /etc/yum.repos.d/ol7-temp.repo /etc/yum.repos.d/ol7-temp.repo.disabled

You are now ready to install additional software. See: Installing Software from Oracle Linux Yum Server

If you want to update your system, proceed with the following command:

# yum update -y

Red Hat Enterprise Linux 8

1. Import the Oracle Linux GPG key using these instructions.

2. Ceate a temporary yum repository configuration file /etc/yum.repos.d/ol8-temp.repo with the following as the minimum required content:

[ol8_baseos_latest]
name=Oracle Linux 8 BaseOS Latest ($basearch)
baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/baseos/latest/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1

4. Remove ol8-temp.repo and any other remaining repo files that may conflict with Oracle Linux yum server:

# mv /etc/yum.repos.d/ol8-temp.repo /etc/yum.repos.d/ol8-temp.repo.disabled

You are now ready to install additional software. See: Installing Software from Oracle Linux Yum Server

[OPTIONAL] To update your system, proceed with the following command:

# dnf update --setopt=ol8_appstream.module_hotfixes=true --allowerasing -y

Red Hat Enterprise Linux 9

1. Import the Oracle Linux GPG key using these instructions.

2. Ceate a temporary yum repository configuration file /etc/yum.repos.d/ol9-temp.repo with the following as the minimum required content:

[ol9_baseos_latest]
name=Oracle Linux 9 BaseOS Latest  ($basearch)
baseurl=https://yum.oracle.com/repo/OracleLinux/OL9/baseos/latest/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

Connecting To Yum Mirrors in Oracle Cloud Infrastructure (OCI)

Each region in Oracle Linux Cloud Infrastructure (OCI) has its own Oracle Linux yum server mirror to enable high speed access without incurring extra network charges. When launched, Oracle Linux images have a yum variable set in /etc/yum/vars/ociregion to ensure they connect to a mirror in the appropriate OCI region.

If /etc/yum/vars/ociregion is not set, or not set correctly, run the following

	$ sudo touch /etc/yum/vars/ociregion
	$ OCIREGION=$(curl -sfm 3 http://169.254.169.254/opc/v1/instance/ | jq -r '.region' | cut -d '-' -f 2)
	$ sudo sh -c "echo -$OCIREGION > /etc/yum/vars/ociregion"
