Quick start for using yum on Red Hat Linux 7.3
This quick start documentation expects that you're already comfortable with shell usage and RPM handling. If you're unsure about anything in this document, it is suggested that you switch over to the Detailed HowTo Instructions instead.
In order to install yum, you'll need the gnupg, python and rpm-python packages. Please make sure they're all installed.
yum is available through the legacy-utils channel of your public repository, which you can find at http://download.fedoralegacy.org/redhat/7.3/legacy-utils/i386/. Please download the latest yum package and install it on your system. yum automatically uses the correct configuration for your system (7.2 or 7.3), so you can install the above RPM on any 7.2 or 7.3 systems.
Optionally add mirror sites
You may want to configure it to use additional mirror sites which are closer to you, faster, or meet your security policy. Select a mirror from the list of mirrors and change your yum.conf accordingly.
Add the GPG keys to root's keyring

Update your system
Once you have installed the yum package, you should run the following command as the root user on your system to update your system:
Decide if you want automatic updates
yum has the ability to automatically apply (download/verify/install) all updates to your system, but this feature is disabled by default. If you want to enable that functionality, please enter the following command as the root user on your system:
