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 Unixbased
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 serverroot. 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 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.
-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 mod-ules modules
ules 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 set-tings). settings).
tings).
-t Run syntax tests for configuration files only. The program immediately exits after these syn-tax syntax
tax 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.
