yum upgradeThis command will upgrade all of the packages on your system to the latest version.
- If you want to upgrade just a single package, you can use the following command:
yum update <package_name>
Replace <package_name> with the name of the package you want to update.
- After the upgrade is complete, you should reboot your system to apply the changes. You can do this by typing the following command:
reboot
