a2enmod

a2enmod is a command line tool used in Linux-based systems, specifically in Apache HTTP Server. The tool is primarily used to enable Apache modules, which are extensions that enhance the functionality of the server. It simplifies the process of enabling modules by providing an easy-to-use interface. The name "a2enmod" stands for "Apache 2 Enable Module", indicating its purpose and compatibility with Apache 2 version. By running the a2enmod command followed by the desired module name, the user can quickly activate the module, making it available for Apache to use. The command also handles all the necessary steps needed to enable a module, such as creating symlinks in the appropriate directories. In case the module requires additional configuration, a2enmod may prompt the user for further input or provide instructions. Conversely, the counterpart command a2dismod (Apache 2 Disable Module) can be used to disable modules if they are no longer required. a2enmod is a convenient tool for managing and fine-tuning the functionality of an Apache HTTP Server by enabling or disabling modules.
