apache2 is the Apache HyperText Transfer Protocol (HTTP) server program. It is designed to be run as a standalone daemon process. When used like this it will create a pool of child processes or threads to handle requests. In general, apache2 should not be invoked directly, but rather should be invoked via /etc/init.d/apache2 or apache2ctl. The default Debian configuration requires environment variables that are defined in /etc/apache2/envvars and are not available if apache2 is started directly. However, apache2ctl can be used to pass arbitrary arguments to apache2.
The full documentation is available in the apache2-doc package or at http://httpd.apache.org/docs/2.2/ . Information about Debian specific changes and configuration can be found in /usr/share/doc/apache2/README.Debian.gz .
-d serverroot Set the initial value for the ServerRoot directive to serverroot. This can be overridden by the ServerRoot directive in the configuration file. -f config Uses the directives in the file config on startup. If config does not begin with a /, then it is taken to be a path relative to the ServerRoot. The default is /etc/apache2/apache2.conf. -k start|restart|graceful|stop|graceful-stop Signals apache2 to start, restart, or stop. See Stopping Apache for more information. -C directive Process the configuration directive before reading config files. -c directive Process the configuration directive after reading config files. -D parameter Sets a configuration parameter which can be used with <IfDefine> sections in the configuration files to conditionally skip or process commands at server startup and restart. -e level Sets the LogLevel to level during server startup. This is useful for temporarily increasing the verbosity of the error messages to find problems during startup. -E file Send error messages during server startup to file. -R directory When the server is compiled using the SHARED_CORE rule, this specifies the directory for the shared object files. -h Output a short summary of available command line options. -l Output a list of modules compiled into the server. This will not list dynamically loaded modules included using the LoadModule directive. -L Output a list of directives together with expected arguments and places where the directive is valid. -M Dump a list of loaded Static and Shared Modules. -S Show the settings as parsed from the config file (currently only shows the virtualhost settings). -t Run syntax tests for configuration files only. The program immediately exits after these syntax parsing tests with either a return code of 0 (Syntax OK) or return code not equal to 0 (Syntax Error). If -D DUMP_VHOSTS is also set, details of the virtual host configuration will be printed. If -D DUMP_MODULES is set, all loaded modules will be printed. -v Print the version of apache2, and then exit. -V Print the version and build parameters of apache2, and then exit. -X Run apache2 in debug mode. Only one worker will be started and the server will not detach from the console.
