GUI config utility question

edit

Not sure if it's an overkill in your case, but you could install cockpit from the official Fedora repository. There was an introduction in the Fedora Magazine.

sudo dnf install cockpit
sudo systemctl enable --now cockpit.socket
sudo firewall-cmd --add-service=cockpit

(--permanent makes that change to the firewall permanent)

Then: http://localhost:1001

To be very honest with you, the best GUI config tool that I know is the text editor of your choice (i.e. gedit)

If you don't like that answer, the following may help:

• For Apache's http server, there is: system-config-httpd (never used, so no clue if it's any good).
• For NFS, there used to be system-config-nfs. That has been retired (it provided very basic settings anyway). You will quickly learn to edit /etc/exports and nfs.conf files directly).
• For systemd: I don't know of any GUI tool but you will learn to use systemctlpretty fast to do stuff like enabling, disabling, starting, stopping, and troubleshooting services.
