Working with the Apache configuration file

## The location of the Apache configuration file On most systems if you installed Apache with a package manager, or it came preinstalled, the Apache configuration file is located in one of these locations: - /etc/apache2/httpd.conf - /etc/apache2/apache2.conf - /etc/httpd/httpd.conf - /etc/httpd/conf/httpd.conf If you installed Apache from source it is likely located in /usr/local or /opt, though the config files may have been moved to /etc as usual. Check your build script for more details. Furthermore On macOS Server >= 10.8 Mountain Lion, the location of the Apache configuration file varies. Some paths are listed below, please refer to the macOS Server documentation for complete information. | Not using websites/webservices | default (/etc/apache2/httpd.conf) | | macOS Server 4 webservices | /Library/Server/Web/Config/apache2/httpd_server_app.conf | | macOS Server 5 websites | /Library/Server/Web/Config/apache2/server-httpd.conf | ## mods-enabled and sites-enabled To allow better organization, many operating systems and Apache distributions also read configuration files in the conf.d, mods-enabled and sites-enabled subdirectories. mods-enabled contains symlinks to files in mods-available. This latter subdirectory contains config files for all available modules, while mods-enabled contains only a subset, namely the modules that should actually be enabled. The symlinks are created using the a2enmod tool. *.load files contain LoadModule directives, while *.conf files contain all other configuration directives. ## Storing Passenger configuration snippets If you can, you should use mods-enabled/mods-available to store Passenger configuration. Assuming that your Apache configuration directory is /etc/apache2: - Create /etc/apache2/mods-available/passenger.load and paste the LoadModule ... directive that passenger-install-apache2-module outputs. - Create /etc/apache2/mods-available/passenger.conf and paste the PassengerRoot and other Passenger options. - Enable by running sudo a2enmod passenger. If the mods-enabled mechanism is not available then you can paste configuration snippets into httpd.conf or apache2.conf directly.
