It puts the pieces +# together by including all remaining configuration files when starting up the +# web server. +# +# * ports.conf is always included from the main configuration file. It is +# supposed to determine listening ports for incoming connections which can be +# customized anytime. +# +# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/ +# directories contain particular configuration snippets which manage modules, +# global configuration fragments, or virtual host configurations, +# respectively. +# +# They are activated by symlinking available configuration files from their +# respective *-available/ counterparts. These should be managed by using our +# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See +# their respective man pages for detailed information. +# +# * The binary is called apache2. Due to the use of environment variables, in +# the default configuration, apache2 needs to be started/stopped with +# /etc/init.d/apache2 or apache2ctl.
