| <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> |

| <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> |

| files.</dd> |

| |
| <dd>Sets a configuration <var>parameter </var>which can be used with |
| <code class="directive"><a href="../mod/core.html#ifdefine"><IfDefine></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> |

| |
| <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> |

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

| 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. If -D <var>DUMP</var>_<var>CERTS </var> |
| is set and <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> is used, configured SSL certificates will |
