# Install RPM packages

RPM You will find RPM's everywhere and for the considerable future. It is very simple to install one of these

# wget url
wget http://some_website/sample_file.rpm

sudo rpm -i sample_file.rpm

sudo yum localinstall sample_file.rpm

sudo rpm -i sample_file.rpm

sudo dnf localinstall sample_file.rpm

Unlike many Linux tools, DNF is not a set of initials. It is merely the next evolution of the yum package manager.

The RPM installer can be used to remove (or uninstall) a software package.

Enter the following into a terminal window:

sudo rpm -e sample_file.rpm

The -e option instructs RPM to erase the software.

So far, this guide assumes the software either doesn’t have dependencies or already has them installed.

To check the .rpm file for dependencies using the following command:

sudo rpm -qpR sample_file.rpm

• The system should list all the dependencies:

-q – This option tells RPM to query the file -p – This option lets you specify the target package to query -R – This lists the requirements for the package

If there are any missing dependencies, you can install them from the standard repositories using yum or dnf. If your software requires other non-standard software, it will often be noted in the installation instructions.

One exciting feature of the yum package manager is that it allows you to download .rpm files directly from the repository. This might be helpful if you have limited bandwidth, or want to copy a single downloaded file between systems. It could also help if you have intermittent internet access, and you don’t want to spend time waiting for your installer to finish.

To download a .rpm file from the repositories, enter the following:

sudo yumdownloader packagename

If you wanted to download the files for Apache, for instance, you’d replace packagename with httpd. You can then install the file as above
