Linux package management with YUM and RPM

Installing, patching, and removing software packages on Linux machines is one of the common tasks every sysadmin has to do. Here is how to get started with Linux package management in Linux Red Hat-based distributions (distros).

Package management is a method of installing, updating, removing, and keeping track of software updates from specific repositories (repos) in the Linux system. Linux distros often use different package management tools. Red Hat-based distros use RPM (RPM Package Manager) and YUM/DNF (Yellow Dog Updater, Modified/Dandified YUM).

Yellow Dog Updater, Modified (YUM)

[ Editor’s Note: DNF or Dandified YUM is the updated default since Red Hat Enterprise Linux 8, CentOS 8, Fedora 22, and any distros based on these. Generally, the options are the same. Read more about DNF here. ]

YUM is the primary package management tool for installing, updating, removing, and managing software packages in Red Hat Enterprise Linux. YUM performs dependency resolution when installing, updating, and removing software packages. YUM can manage packages from installed repositories in the system or from .rpm packages. The main configuration file for YUM is at /etc/yum.conf , and all the repos are at /etc/yum.repos.d .

You can learn more about adding repositories to your system from this article on how to add a YUM repo from Amy Marrich.

It’s easy to manage packages in Linux with YUM . At the command line, enter:

There are many options and commands available to use with YUM . I’ve listed some commonly-used commands for YUM below:

Command	Purpose
yum install	Installs the specified packages
remove	Removes the specified packages
search	Searches package metadata for keywords
info	Lists description
update	Updates each package to the latest version
repolist	Lists repositories
history	Displays what has happened in past transactions

The following are commonly-used options with YUM :

Options	Purpose
-C	Runs from system cache
—security	Includes packages that provide a fix for a security issue
-y	Answers yes to all questions
—skip-broken	Skips packages causing problems
-v	Verbose

The history option gives you an overview of what happened in past transactions. This provides some useful information, like the date when the transaction happened and what command was run.

You can undo or redo certain transactions using the history command. Here is an example of undoing a transaction:

YUM provides many options for package management. For detailed option information, look at man yum and yum –help . Also, here is a link to YUM documentation.

RPM is a popular package management tool in Red Hat Enterprise Linux-based distros. Using RPM , you can install, uninstall, and query individual software packages. Still, it cannot manage dependency resolution like YUM . RPM does provide you useful output, including a list of required packages. An RPM package consists of an archive of files and metadata. Metadata includes helper scripts, file attributes, and information about packages.

RPM maintains a database of installed packages, which enables powerful and fast queries. The RPM database is inside /var/lib , and the file is named __db* .

RPM has some basic modes: query, verify, install, upgrade, erase, show querytags, show configuration. At least one of these modes needs to be selected to perform package management tasks. Every mode has its own set of options. For example, install mode i has its own set of installation options. Options for the modes are found on the RPM man pages at man rpm .

Some commonly-used modes are listed below:

Mode	Description
-i	Installs a package
-U	Upgrades a package
-e	Erases a package
-V	Verifies a package
-q	Queries a package

Here are some commonly-used general options:

General options	Purpose
-? | —help	Prints help
—version	Prints version number
-v	Prints verbose output

To install or upgrade an .rpm package using RPM, issue this command:

The flag -i is for install, U is for upgrade, v for verbose, h for hash (this option displays the # as a progress bar for the operation). In this example, v and h are optional flags.

To query for a package using RPM issue following command:

rpm -q query-options package

Option a queries all installed packages on the system.

To erase a package, use the following command:

rpm -e erase-options package-name

Package management is a common task for every system. YUM and RPM provide efficient ways to install, upgrade, remove, and track software packages on Red Hat Enterprise Linux systems.

How to Install RPM Files on Fedora Linux [Beginner’s Tutorial]

When you start using Fedora Linux in the Red Hat domain, sooner or later, you’ll come across .rpm files. Like .exe files in Windows and .deb files in Ubuntu and Debian, .rpm files enable you to quickly install a software from it on Fedora.

You could find and install plenty of software from the software center, specially if you enable additional repositories in Fedora. But sometimes you’ll find software available on their website in RPM format.

Like .exe files in Windows, you download the .rpm file and double click on it to install it. Don’t worry, I’ll show you the detailed steps.

Installing RPM files on Fedora and Red Hat Linux

I’ll be showing you three ways to install RPM files:

Method 1: Use software center

The simplest method is to use the default software center in Fedora. It’s really simple. Go to the folder where you downloaded the .rpm file. It is usually the Downloads folder.

Just double click on the RPM file and it will be opened in the software center.

Alternatively, you can right click on the file and choose to install it via Software Center.

When it is opened in the software center, you should see the installation option. Just hit the install button and enter your account’s password when prompted for it.

Method 2: Use DNF command to install RPM file

This is the command line method. Fedora uses the new DNF package manager and you can use it to install downloaded RPM files as well.

Open a terminal and switch to the directory where you have the RPM file downloaded. You can also provide the path to the RPM file. Use the DNF command like this:

sudo dnf install rpm_file_name

Method 3: Install RPM files in Red Hat using Yum command

Unlike Fedora, Red Hat still uses the good old Yum package manager. You won’t find the DNF command here, yet.

The process is the same as DNF command. You go to the directory where the RPM file is located or provide its path.

sudo yum install path_to_RPM_file

How to remove RPM packages

Removing a RPM package isn’t a big deal either. And no, you don’t need the original rpm file that you used to install the program.

You may find the installed package in the software center and remove application from there.

Alternatively, you can use the DNF or YUM command with remove option.

With DNF, use this command:

sudo dnf remove rpm_package_name

With Yum, use this command:

sudo yum remove rpm_package_name

You probably won’t remember the exact package name and that’s fine. What you can do is to type the first few letters of the package and then hit tab. This is assuming that you have tab completion enabled which usually is.

And that’s all you need to do here. Pretty simple, right? Being a beginner, you may struggle with a simple task like this and I hope you feel more confident with Fedora thanks to quick tutorials like this.

How to install software packages on Red Hat Enterprise Linux (RHEL)

Learn how to install software with RHEL’s package manager using the dnf command or the GNOME Software app.

There’s a lot of flexibility in how you install an application on Linux. It’s partly up to the software’s developer to decide how to deliver it to you. In many cases, there’s more than one «right» way to install something.

Training & certification

However, when an application is mission-critical, it’s important that you get timely and reliable updates. The best way for that to happen is to install software from a central hub. On Red Hat Enterprise Linux (RHEL), that central hub for application installation and maintenance is the dnf (formerly known as yum ) package manager.

Using a package manager ensures that every file installed on your system is dutifully recorded in a database, and each package can be updated when a new release is available. RHEL provides two ways to interact with its package manager: the dnf command and the GNOME Software app.

Search software repositories

Applications available on Red Hat’s servers are divided into several software repositories. These include the BaseOS, AppStream, Red Hat Linux Builder (previously called CodeReady Linux Builder), and Supplementary repositories.

To see the repositories enabled on your system, use the dnf repolist command along with the —all option. It’s a long list, so pipe it through the more pager to scroll through it:

$ sudo dnf repolist --all | more amq-interconnect-textonly-1-for-middleware-rpms Red Hat A disabled amq-textonly-1-for-middleware-rpms Red Hat J disabled ansible-automation-platform-2.2-for-rhel-9-. Red Hat A disabled ansible-automation-platform-2.2-for-rhel-9-. Red Hat A disabled ansible-automation-platform-2.2-for-rhel-9-. Red Hat A disabled codeready-builder-for-rhel-9-x86_64-debug-rpms Red Hat C disabled codeready-builder-for-rhel-9-x86_64-eus-debug-rpms Red Hat C disabled codeready-builder-for-rhel-9-x86_64-eus-rpms Red Hat C disabled codeready-builder-for-rhel-9-x86_64-eus-source. Red Hat C disabled codeready-builder-for-rhel-9-x86_64-rpms Red Hat C enabled codeready-builder-for-rhel-9-x86_64-source-rpms Red Hat C disabled [. ]

To enable a repository, use the dnf config-manager subcommand with the —enable option and the name of the repository as listed. For instance, to enable the rhel-9-for-x86_64-supplementary-rpms repository:

$ sudo dnf config-manager --enable rhel-9-for-x86_64-supplementary-rpms Updating Subscription Management repositories.

Find software to install

If you know what application you want to install, you can verify that it’s in the repository by searching for its name or even just part of its name:

$ sudo dnf search toolbox Updating Subscription Management repositories. ==== Name Exactly Matched: toolbox =========== toolbox.x86_64 : Tool for containerized command line environments on Linux

Install software from a remote repository

To install an application, use the install subcommand:

How to Install Software in Red Hat Linux

wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. To create this article, 12 people, some anonymous, worked to edit and improve it over time.

This article has been viewed 136,928 times.

If your Red Hat Linux PC doesn’t include all the software you want, you can install additional software from the internet (whether you have broadband or dial-up) or removable media. This can be accomplished graphically or using the command line.

Understand Linux software.

Open a terminal window.

Open a Terminal . You’ll find Terminal in Applications > System Tools, or you can right-click the desktop and select Terminal.

Become the root user.

If you’re installing system-wide software, you’ll need administrative privileges. Type su — and type the root password when prompted.

Update the package lists.

To get the latest software packages, you’ll need to update the yum package manager. To do this, just type yum check-update and press Enter.

Install a package using yum.

Type yum install «program name» and press ↵ Enter . For example, to install the Dillo web browser, you would type yum install dillo .

Confirm the installation.

Press the Y key to start installing the software. The software will now install. Once the installation is complete, you’ll return to the command prompt.
