Chapter 16. Updating Red Hat Certificate System
To update Certificate System and the operating system it is running on, use the dnf update
command. This downloads, verifies, and installs updates for Certificate System as well as operating system packages.
For example:
dnf update
# dnf update
Copy to Clipboard Copied! Toggle word wrap Toggle overflow This downloads, verifies, and installs updates for Certificate System as well as operating system packages. You can verify the version number before and after updating packages, to confirm they were successfully installed.
Updating Certificate System requires the PKI infrastructure to be restarted. We suggest scheduling a maintenance window to take the PKI infrastructure offline and install the update.
To optionally download updates without installing, use the
--downloadonly
option in the above procedure:dnf update --downloadonly
# dnf update --downloadonly
Copy to Clipboard Copied! Toggle word wrap Toggle overflow The downloaded packages are stored in the
/var/cache/yum/
directory.
Thednf update
will later use the packages if they are the latest versions.
