There are a few different ways that you can install an RPM package on RHEL 8. They each have their own merits, but DNF should probably be your first choice in most situations. It's also good to remember that, for stability's sake, it's a good idea to limit your external RPM installs as much as possible.

How to Install an RPM with DNF

As stated earlier, DNF is Red Hat's package manager, and it's the best option for handling individual RPM packages. DNF handles dependency resolution, and that's a very big deal when dealing with individual packages on any Linux system. It prevents potential conflicts and semi-broken packages. You'll also be spared the hassle of tracking down dependencies yourself.

To install an RPM with DNF, simply give DNF the location of the RPM instead of the package name, like you normally would.

# dnf install /path/to/package.rpm

It works with RPMs located on the web too. Give DNF the direct web address of the RPM.

# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

DNF will automatically include any dependencies in the installation, and it shows them when it asks you to confirm the package install. In the case the package isn't compatible, DNF will let you know that too.

How to Install an RPM with Yum

This section will be brief. Yum on RHEL 8 is DNF. With this release, Red Hat removed Yum in favor of DNF, but they provided a simple wrapper, allowing you to continue using the yum command. So, if you want to use "Yum" to install an RPM, you can, but it's really DNF, and the syntax is identical.

# yum install /path/to/package.rpm

How to Install an RPM with RPM

The traditional method for installing RPM packages is the RPM package utility. It's the original way to install packages on a Red Hat system, and it does still work, but it has its limitations. Most notably, RPM doesn't handle dependency resolution. That means, if you're going to go this route, be prepared because things can get messy fast.

To use install a package with the rpm command, use the -i flag, and give it the path to your package.



# rpm -i /path/to/package.rpm

Conclusion

Stick to DNF for most situations, and things will go smoothly. While you might need to use RPM in some rare niche situations, DNF will almost always be the best bet, especially considering dependencies.
