To apply package updates on a CentOS Linux system, you can use the yum command. The yum command is a package manager that is used to install, update, and remove packages on CentOS systems.
Here's an example of how to use the yum command to apply package updates on a CentOS Linux system:
yum update
This command will update all the installed packages on your system to the latest available versions.
You can also use the yum command to update a specific package. For example, to update the openssl package, you can use the following command:
yum update openssl
Before applying the updates, the yum command will show you a list of packages that will be updated and the size of the update. You can choose to accept or reject the updates by pressing y or n, respectively.
