Therefore, you do not need to worry about the distinction between installing and upgrading a kernel package when you use yum : it will do the right thing, regardless of whether you are using the yum update or yum install command.

When using RPM , on the other hand, it is important to use the rpm -i kernel command which installs a new kernel instead of rpm -u kernel which replaces the current kernel. See Section B. To update all packages and their dependencies, enter yum update without any arguments :. Discovering which packages have security updates available and then updating those packages quickly and easily is important.

Yum provides the plug-in for this purpose. The security plug-in extends the yum command with a set of highly-useful security-centric commands, subcommands and options. It is also possible to set up periodical automatic updates for your packages. For this purpose, Red Hat Enterprise Linux 6 uses the yum-cron package. It provides a Yum interface for the cron daemon and downloads metadata from your package repositories. With the yum-cron service enabled, the user can schedule an automated daily Yum update as a cron job.

The yum-cron package is provided by the Optional subscription channel. To install yum-cron issue the following command:. By default, the yum-cron service is disabled and needs to be activated and started manually:.

The script included in the yum-cron package can be configured to change the extent and frequency of the updates, as well as to send notifications to e-mail. Preserving Configuration File Changes. You will inevitably make changes to the configuration files installed by packages as you use your Red Hat Enterprise Linux system. RPM , which Yum uses to perform changes to the system, provides a mechanism for ensuring their integrity.

For systems that are disconnected from the Internet or Red Hat Network, using the yum update command with the Red Hat Enterprise Linux installation ISO image is an easy and quick way to upgrade systems to the latest minor version. The following steps illustrate the upgrading process:. Create a target directory to mount your ISO image. This directory is not automatically created when mounting, so create it before proceeding to the next step. BG Community Member 24 points.

RPM maintains a database of installed packages, which enables powerful and fast queries. 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. 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. Package management is a common task for every system. Download it now for free. When he is not playing in the CLI, you will find him playing Cricket.
