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 systems or as a service on Windows NT, 2000 and XP and as a console application on Windows 9x and ME.

OPTIONS

Tag	Description
-d serverroot
	Set the initial value for the ServerRoot directive to serverroot. This can be overridden by the ServerRoot 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 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 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 console.
The following arguments are available only on the Windows platform:
-k install\|config\|uninstall
	Install Apache as a Windows NT service; change startup options for the Apache service; and uninstall the Apache service.
-n name
	The name of the Apache service to signal.
-w	Keep the console window open on error so that the error message can be read.
