A server is a computer system that provides specific services within a computer network. It is supported by a scalable processor and large RAM and is equipped with a specialized operating system. One type of server is a web server, which handles HTTP or HTTPS requests from browsers and delivers web pages in the form of HTML and CSS files. Server virtualization applications such as OpenVZ and Proxmox VE are available for creating server virtualizations. Proxmox VE, a company founded in 2008, is a Linux Debian-based operating system that focuses on its use as a virtualization platform. One of the operating systems that can be used in Proxmox is Ubuntu, a Linux operating system that supports multi-user and multi-tasking environments and is freely available. Apache is a widely favored web server due to its compactness, modular design, compliance with HTTP protocol standards, and a much larger user base compared to its competitors. This study will discuss the installation of the Apache web server on an Ubuntu server using Proxmox server. Apache is the most popular and widely used web server in the world. The strengths of Apache lie in its flexibility and ability to handle various types of web content, including static pages, dynamic content, and scripts. Based on these considerations, the researcher will conduct an Apache web server installation on an Ubuntu server using Proxmox.
