Cockpit is a lightweight, web-based server management tool that makes it easy to monitor and administer CentOS systems. It provides a clean interface for managing services, storage, networks, containers, and user accounts. Installing Cockpit on CentOS is straightforward and can be done in just a few steps.

Enable and Start Cockpit Service

Cockpit is included in CentOS by default, so you don’t need to install additional repositories in most cases. First, ensure the service is enabled and running:

• Run sudo systemctl enable --now cockpit.socket to enable and start the Cockpit socket
• This command activates the web console and sets it to start automatically on boot
• The service runs on port 9090 by default

Configure Firewall Access

To access Cockpit from a remote browser, you must allow traffic through the firewall:

• Use sudo firewall-cmd --permanent --add-service=cockpit to open the required port
• Then reload the firewall with sudo firewall-cmd --reload
• This permits access to the web interface from other machines on the network

Access the Web Interface

Once installed and configured, open a web browser and navigate to:

• http://your-server-ip:9090
• Log in using your system’s username and password (must have sudo or appropriate permissions)
• You’ll see an overview of system resources, logs, and available administration tools

Make sure SELinux is in enforcing mode and up to date, as Cockpit works best when security policies are active. If you’re behind a corporate firewall or NAT, ensure port 9090 is accessible and not blocked.

Basically just enable the service, adjust the firewall, and log in. No extra packages needed on standard CentOS installations.
