To find out the latest available updated packages or kernel version on a CentOS or Red Hat Enterprise Linux (RHEL) system, you can use the yum
package manager and the yum check-update
command.
For example, to check for updates for all packages, you can run the following command:
sudo yum check-update
This will display a list of available updates for the installed packages. If an update is available for a package, the package name and the new version number will be displayed.
To check for updates for a specific package, you can use the yum check-update
command followed by the package name. For example, to check for updates for the httpd
package:
sudo yum check-update httpd
To check for updates for the kernel package, you can use the yum check-update
command with the kernel
package name:
sudo yum check-update kernel
This will display the latest available version of the kernel package.
Note: The
yum check-update
command does not install the updates. It only checks for available updates and displays a list of the updates that are available. To install the updates, you can use theyum update
command.
Note: It is a good idea to keep your system up to date with the latest security updates and bug fixes. However, it is important to test the updates in a staging environment before deploying them in a production environment, as there is a risk of data loss or corruption during the update process. It is also a good idea to make a backup of any important data before installing the updates.
