An online forum server typically requires the following: a web server (such as Apache or Nginx) to serve HTML pages and handle user requests, a database server (such as MySQL or PostgreSQL) to store forum data, a PHP or other programming language runtime environment to handle server-side logic, and a forum software (such as phpBB or SMF) to handle the forum's specific functionality.
The server should also have enough storage and processing power to handle a high volume of user traffic and data, as well as appropriate security measures to protect user data and prevent unauthorized access. A server should also be updated and maintained regularly to ensure the smooth operation of the forum.
