AlmaLinux, a community-driven Linux distribution, has become a popular choice for users looking for a stable and secure operating system. Its compatibility with Red Hat Enterprise Linux (RHEL) makes it ideal for enterprise environments. One of the tools that simplifies managing AlmaLinux servers is the Web Admin Console. This browser-based interface allows administrators to manage system settings, monitor performance, and configure services without needing to rely solely on the command line.

In this blog post, we’ll walk you through the process of setting up and using the Web Admin Console on AlmaLinux, helping you streamline server administration tasks with ease.

What Is the Web Admin Console?

The Web Admin Console, commonly powered by Cockpit, is a lightweight and user-friendly web-based interface for server management. Cockpit provides an intuitive dashboard where you can perform tasks such as:

  • Viewing system logs and resource usage.
  • Managing user accounts and permissions.
  • Configuring network settings.
  • Installing and updating software packages.
  • Monitoring and starting/stopping services.

It is especially useful for system administrators who prefer a graphical interface or need quick, remote access to manage servers.

Why Use the Web Admin Console on AlmaLinux?

While AlmaLinux is robust and reliable, its command-line-centric nature can be daunting for beginners. The Web Admin Console bridges this gap, offering:

  1. Ease of Use: No steep learning curve for managing basic system operations.
  2. Efficiency: Centralized interface for real-time monitoring and quick system adjustments.
  3. Remote Management: Access your server from any device with a browser.
  4. Security: Supports HTTPS for secure communications.

Step-by-Step Guide to Setting Up and Using the Web Admin Console on AlmaLinux

Step 1: Ensure Your AlmaLinux System is Updated

Before installing the Web Admin Console, ensure your system is up to date. Open a terminal and run the following commands:

sudo dnf update -y

This will update all installed packages to their latest versions.

Step 2: Install Cockpit on AlmaLinux

The Web Admin Console on AlmaLinux is powered by Cockpit, which is included in AlmaLinux’s default repositories. To install it, use the following command:

sudo dnf install cockpit -y

Once the installation is complete, you need to start and enable the Cockpit service:

sudo systemctl enable --now cockpit.socket

The --now flag ensures that the service starts immediately after being enabled.

Step 3: Configure Firewall Settings

To access the Web Admin Console remotely, ensure that the appropriate firewall rules are in place. By default, Cockpit listens on port 9090. You’ll need to allow traffic on this port:

sudo firewall-cmd --permanent --add-service=cockpit
sudo firewall-cmd --reload

This ensures that the Web Admin Console is accessible from other devices on your network.

Step 4: Access the Web Admin Console

With Cockpit installed and the firewall configured, you can now access the Web Admin Console. Open your web browser and navigate to:

https://<your-server-ip>:9090

For example, if your server’s IP address is 192.168.1.100, type:

https://192.168.1.100:9090

When accessing the console for the first time, you might encounter a browser warning about an untrusted SSL certificate. This is normal since Cockpit uses a self-signed certificate. You can proceed by accepting the warning.

Step 5: Log In to the Web Admin Console

You’ll be prompted to log in with your server’s credentials. Use the username and password of a user with administrative privileges. If your AlmaLinux server is integrated with Active Directory or other authentication mechanisms, you can use those credentials as well.

Once logged in, you’ll see a dashboard displaying an overview of your ### How to Use Web Admin Console on AlmaLinux: A Step-by-Step Guide
