SYNOPSIShttpd [ -d serverroot ] [ -f config ] [ -C directive ] [ -c directive ]
[ -D parameter ] [ -e level ] [ -E file ] [ -k start|restart|grace‐
ful|stop|graceful-stop ] [ -R directory ] [ -h ] [ -l ] [ -L ] [ -S ] [

On Windows systems, the following additional arguments are available:
httpd [ -k install|config|uninstall ] [ -n name ] [ -w ]
SUMMARYhttpd 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
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.
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/pkg/share/httpd/htdocs.
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.
Signals httpd to start, restart, or stop. See Stopping Apache
for more information.
Process the configuration directive before reading config files.
Process the configuration directive after reading config files.
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).
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.
Send error messages during server startup to file.
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
-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 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:
Install Apache as a Windows NT service; change startup options
for the Apache service; and uninstall the Apache service.
The name of the Apache service to signal.
-w Keep the console window open on error so that the error message
can be read.
