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 <a href="apachectl.html">apachectl</a> 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> </summary> <seealso><a href="../invoking.html">Starting Apache</a></seealso> <seealso><a href="../stopping.html">Stopping Apache</a></seealso> <seealso><a href="../configuring.html">Configuration Files</a></seealso> <seealso><a href="../platform/">Platform Docs</a></seealso> <seealso><a href="apachectl.html">apachectl</a></seealso> <section id="synopsis"><title>Synopsis</title> <p><code><strong>httpd </strong>[ -<strong>d </strong><var>serverroot </var>] [ -<strong>f </strong><var>config </var>] [ -<strong>C </strong> <var>directive </var>] [ -<strong>c </strong> <var>directive</var>] [ -<strong>D </strong> <var>parameter </var>] [ -<strong>e </strong> <var>level</var> ] [ -<strong>E </strong> <var>file</var> ] [ <strong>-k </strong> <code>start|restart|graceful|stop</code> ] [ -<strong>R </strong> <var>directory</var> ] [ -<strong>h </strong>] [ -<strong>l </strong>] [ -<strong>L </strong>] [-<strong>S</strong>] [ -<strong>t </strong>] [ -<strong>v </strong>] [ -<strong>V </strong>] [ -<strong>X </strong>]</code></p> <p>On <a href="../platform/windows.html">Win32 systems</a>, the following additional arguments are available:</p> <p><code><strong>httpd </strong> [ -<strong>k </strong> <code>install|config|uninstall</code> ] [ -<strong>n </strong> <var>name</var> ] [ -<strong>w</strong> ]</code></p> </section> <section id="options"><title>Options</title> <dl> <dt><code>-d <var>serverroot</var></code></dt> <dd>Set the initial value for the <directive module="core">ServerRoot</directive> directive to <var>serverroot</var>.
