Which file contains the configuration settings for the Apache web server?

The Apache web server uses a primary configuration file called 'httpd.conf'. This file plays a crucial role in defining the server's settings and behavior. It includes directives to configure aspects such as the document root, server settings, modules to load, and other operational parameters.

While there are other files that can be utilized for configuration, such as 'apache.conf' or 'server.conf', they are not the standard main configuration file for the Apache web server. The naming convention and the established use within the community define 'httpd.conf' as the central file for configuring Apache, making it the go-to reference for server setup and management.

Understanding the significance of 'httpd.conf' gives a solid foundation for managing an Apache server effectively, as it outlines all necessary settings that dictate how the server operates and interacts with web requests.
