     <p><code>httpd</code> 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.</p>

     <p>In general, <code>httpd</code> should not be invoked directly,
     but rather should be invoked via <code class="program"><a href="../programs/apachectl.html">apachectl</a></code> on Unix-based systems or <a href="../platform/windows.html#winsvc">as a service on Windows NT,
     2000 and XP</a> and <a href="../platform/windows.html#wincons">as
     a console application on Windows 9x and ME</a>.</p>

<h2><a name="options" id="options">Options</a></h2>

<dl>
<dt><code>-d <var>serverroot</var></code></dt>

<dd>Set the initial value for the <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code> directive to
<var>serverroot</var>.  This can be overridden by the ServerRoot
directive in the configuration file. The default is
<code>/usr/local/apache2</code>.</dd>

<dt><code>-f <var>config</var></code></dt>

<dd>Uses the directives in the file <var>config</var> on startup. If
<var>config</var> does not begin with a /, then it is taken to be a
path relative to the <code class="directive"><a href="../mod/core.html#serverroot">ServerRoot</a></code>. The default is
<code>conf/httpd.conf</code>.</dd>

<dt><code>-k <code>start|restart|graceful|stop|graceful-stop</code></code></dt>

<dd>Signals <code>httpd</code> to start, restart, or stop.  See <a href="../stopping.html">Stopping Apache httpd</a> for more information.</dd>

<dt><code>-C <var>directive</var></code></dt>

<dd>Process the configuration <var>directive</var> before reading
config files.</dd>

<dt><code>-c <var>directive</var></code></dt>

<dd>Process the configuration <var>directive</var> after reading config
files.</dd>


<dt><code>-D <var>parameter</var></code></dt>

<dd>Sets a configuration <var>parameter </var>which can be used with
<code class="directive"><a href="../mod/core.html#ifdefine">&lt;IfDefine&gt;</a></code> 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 <code>-DNO_DETACH</code>
(prevent the parent from forking) and <code>-DFOREGROUND</code>
(prevent the parent from calling <code>setsid()</code> et al).</dd>

<dt><code>-e <var>level</var></code></dt>

<dd>Sets the <code class="directive"><a href="../mod/core.html#loglevel">LogLevel</a></code> to
<var>level</var> during server startup.  This is useful for
temporarily increasing the verbosity of the error messages to find
problems during startup.</dd>

<dt><code>-E <var>file</var></code></dt>

<dd>Send error messages during server startup to <var>file</var>.</dd>

<dt><code>-h</code></dt>

<dd>Output a short summary of available command line options.</dd>

<dt><code>-l</code></dt>

<dd>Output a list of modules compiled into the server.  This will
<strong>not</strong> list dynamically loaded modules included using
the <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code> directive.</dd>

<dt><code>-L</code></dt>

<dd>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.</dd>

<dt><code>-M</code></dt>

<dd>Dump a list of loaded Static and Shared Modules.</dd>

<dt><code>-S</code></dt>

<dd>Show the settings as parsed from the config file (currently only
shows the virtualhost settings).</dd>

<dt><code>-T</code> (Available in 2.3.8 and later)</dt>

<dd>Skip document root check at startup/restart.</dd>

<dt><code>-t</code></dt>

<dd>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
<var>DUMP</var>_<var>VHOSTS </var>is also set, details of the virtual host
configuration will be printed. If -D <var>DUMP</var>_<var>MODULES </var> is
set, all loaded modules will be printed.</dd>

<dt><code>-v</code></dt>

<dd>Print the version of <code>httpd</code>, and then exit.</dd>

<dt><code>-V</code></dt>

<dd>Print the version and build parameters of <code>httpd</code>, and
then exit.</dd>

<dt><code>-X</code></dt>

<dd>Run httpd in debug mode.  Only one worker will be started and the
server will not detach from the console.</dd>

</dl>

<p>The following arguments are available only on the <a href="../platform/windows.html">Windows platform</a>:</p>

<dl>

<dt><code>-k install|config|uninstall</code></dt>

<dd>Install Apache httpd as a Windows NT service; change startup options for
the Apache httpd service; and uninstall the Apache httpd service.</dd>

<dt><code>-n <var>name</var></code></dt>

<dd>The <var>name</var> of the Apache httpd service to signal.</dd>

<dt><code>-w</code></dt>

<dd>Keep the console window open on error so that the error message can
be read.</dd>
