SUMMARY
       httpd 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, httpd should not be invoked directly, but rather should be invoked via apachectl on Unix-based sys-
       tems or as a service on Windows NT, 2000 and XP and as a console application on Windows 9x and ME.



OPTIONS
       -d serverroot
              Set  the initial value for the ServerRoot directive to serverroot. This can be overridden by the Server-
              Root directive in the configuration file. The default is /etc/httpd.

       -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 conf/httpd.conf.

       -k start|restart|graceful|stop|graceful-stop
              Signals httpd to start, restart, or stop. See Stopping Apache httpd 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. Also can be used  to  set  certain
              less-common  startup parameters including -DNO_DETACH (prevent the parent from forking) and -DFOREGROUND
              (prevent the parent from calling setsid() et al).

       -e level
              Sets the LogLevel to level during server startup. This is useful for  temporarily  increasing  the  ver-
              bosity 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 (Available in 2.2.17 and later)
              Skip document root check at startup/restart.

       -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 httpd, and then exit.

       -V     Print the version and build parameters of httpd, and then exit.

       -X     Run httpd in debug mode. Only one worker will be started and the server will not detach  from  the  con-
              sole.


       The following arguments are available only on the Windows platform:



       -k install|config|uninstall
              Install  Apache  httpd as a Windows NT service; change startup options for the Apache httpd service; and
              uninstall the Apache httpd service.

       -n name
              The name of the Apache httpd service to signal.

       -w     Keep the console window open on error so that the error message can be read.
