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
-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 /usr/local/apache2.
-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 verbosity of the error messages
to find problems during startup.
-E file
Send error messages during server startup to file.
-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 provided by static modules, together
with expected arguments and places where the directive is valid.
Directives provided by shared modules are not listed.
-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 2.3.8 and later)
Skip document root check at startup/restart.
-t Run syntax tests for configuration files only. The program imme-
diately exits after these syntax parsing tests with either a
return code of 0 (Syntax OK) or return code not equal to 0 (Syn-
tax Error). If -D DUMP_VHOSTS is also set, details of the vir-
tual 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 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.
