httpd - Apache Hypertext Transfer Protocol Server
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.
httpd [ -d

[ -C directive ] [ -c

[ -k start|restart|graceful|stop|graceful-stop ]
[ -R directory ] [ -h ]
[ -l ] [ -L ] [ -S ]
[ -t ] [ -v ] [ -V ]
[ -X ] [ -M ]
On Windows systems, the
following additional arguments are available:
httpd [ -k
install|config|uninstall ] [ -n name ]
[ -w ]
-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.
-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.
