Manage Your Linux Server via Web Interface: Complete Guide

Most people want to have a website, but having one means managing a server. And that may seem painful and costly at first sight, right? Let me tell you that there are Graphic User Interfaces (GUIs) that can help you when managing Linux servers by just installing them. With a Linux Server Web GUI, you can do as much as you want on your server with just a few clicks, and all of this in your web browser; there is no need to access the server command line.

This blog will review GUI examples for managing Linux servers. The process can be made simpler by choosing the right Linux server web GUI that suits your project’s specific needs. So, let’s go!

What is Web-Based Linux Server Management?

Web-based Linux server management involves managing Linux servers through graphical interfaces rather than the command line, simplifying tasks such as configuration, monitoring, and administration.

WHM

Key Features and Benefits

Web Host Manager is designed for system administrators and provides full control of the server as if you were logged into the command line. It allows web hosting providers to add unlimited hosting accounts, new technologies, applications, security, etc.

WHM allows to the host provider the same functions as it was a cPanel but with full system access to it. Credentials for authentication, support sections, security, server configurations, and everything for their clients. They can set up different hosting plans, according to the client needs and server requirements for everyone. Set reseller plans is very simple as setting a cPanel account giving certain privileges to them.

Use Cases

WHM (Web Host Manager) is commonly used by web hosting companies to streamline the management of large numbers of client accounts. For instance, resellers use WHM to create and manage multiple client cPanel accounts, each with its own set of resources like bandwidth and storage, allowing them to offer tailored hosting services. WHM also simplifies tasks like adding domains, managing DNS settings, and configuring email accounts for different clients, all from one interface.

Another use case for WHM is handling server maintenance and optimization. Hosting administrators rely on WHM to monitor server performance, adjust configurations for optimal speed, and implement security patches as needed. It also enables administrators to automate tasks like regular backups, making sure that critical data is saved without manual intervention, which is crucial for maintaining uptime and reliability.
