Cockpit is put in on all RHEL-based Linux distros (comparable to Rocky Linux, AlmaLinux, and CentOS) by default. Nevertheless, it isn’t enabled out of the field. Happily, enabling Cockpit is only a matter of opening a terminal window and issuing the command:

sudo systemctl allow --now cockpit.socket

For those who’re utilizing a Debian (or Ubuntu) based mostly Linux distribution, you’ll have to first set up Cockpit with the command:

  • 389 Listing Server — web-based interface for Open SOURCE LDAP.
  • Session Recording — file classes for person interplay with the server.
  • Subscription Supervisor — handle all RHEL subscriptions.
  • oVirt Dashboard — handle digital machines.
  • ZFS Supervisor — handle ZFS file methods.
  • File Sharing — mana Samba and NFS shares.
  • Navigator — full-featured file supervisor for Cockpit.
  • Benchmark — storage benchmark software.
  • Software program Updates — transactional replace from OpenSUSE.
  • Sensors — record all obtainable sensors present in a machine.

Let me present you the right way to set up the Navigator module.

Set up Navigator on an RHEL-based system

As soon as that completes, set up the module with the command:

We will now replace apt with:
