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 han-
dle 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
-d serverroot
Set the initial value for the ServerRoot directive to server-
root. 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
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
fine> 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 use-
ful for temporarily increasing the verbosity of the error mes-
sages 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 LoadMod-
ule directive.

-L Output a list of directives together with expected arguments
and places where the directive is valid.

-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.

-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.
