linux server patching step by step rhel
Here are the general steps for patching a Linux server running Red Hat Enterprise Linux (RHEL):
Update the package manager's cache:
Run sudo yum update to update the package manager's cache. This will ensure that you have the latest information about available packages and their dependencies.
Install any available package updates:
Run sudo yum upgrade to install all available package updates. This will patch any vulnerabilities and fix any bugs in the system.
Reboot the server:
After installing package updates, it's a good idea to reboot the server to apply the changes. Run sudo reboot to reboot the server.
Check for and install any kernel updates:
Kernel updates often contain important security patches and are important to keep up to date. To check for available kernel updates, run sudo yum update kernel. If any updates are available, install them by running sudo yum upgrade kernel.
Reboot the server:
After installing kernel updates, you'll need to reboot the server again to apply the changes. Run sudo reboot to reboot the server.
Note: These steps are just a general outline and may not cover all the steps needed for patching a particular server. Always be sure to consult the documentation for your specific system and any relevant best practices before patching a production server.
