| .SH "SUMMARY" |
| |
| .PP |
| \fBhttpd\fR 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\&. |
| |
| .PP |
| In general, \fBhttpd\fR 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\&. |
| |
| |
| .SH "OPTIONS" |
| |
| |
| .TP |
| \fB-d \fIserverroot\fR\fR |
| Set the initial value for the ServerRoot directive to \fIserverroot\fR\&. This can be overridden by the ServerRoot directive in the configuration file\&. The default is \fB/usr/local/apache2\fR\&. |
| .TP |
| \fB-f \fIconfig\fR\fR |
| Uses the directives in the file \fIconfig\fR on startup\&. If \fIconfig\fR does not begin with a /, then it is taken to be a path relative to the ServerRoot\&. The default is \fBconf/httpd\&.conf\fR\&. |
| .TP |
| \fB-k \fBstart|restart|graceful|stop|graceful-stop\fR\fR |
| Signals \fBhttpd\fR to start, restart, or stop\&. See Stopping Apache httpd for more information\&. |
| .TP |
| \fB-C \fIdirective\fR\fR |
| Process the configuration \fIdirective\fR before reading config files\&. |
| .TP |
| \fB-c \fIdirective\fR\fR |
| Process the configuration \fIdirective\fR after reading config files\&. |
| .TP |
| \fB-D \fIparameter\fR\fR |
| Sets a configuration \fIparameter \fRwhich 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 \fB-DNO_DETACH\fR (prevent the parent from forking) and \fB-DFOREGROUND\fR (prevent the parent from calling \fBsetsid()\fR et al)\&. |
| .TP |
| \fB-e \fIlevel\fR\fR |
| Sets the LogLevel to \fIlevel\fR during server startup\&. This is useful for temporarily increasing the verbosity of the error messages to find problems during startup\&. |
| .TP |
| \fB-E \fIfile\fR\fR |
| Send error messages during server startup to \fIfile\fR\&. |
| .TP |
| \fB-h\fR |
| Output a short summary of available command line options\&. |
| .TP |
| \fB-l\fR |
| Output a list of modules compiled into the server\&. This will \fBnot\fR list dynamically loaded modules included using the LoadModule directive\&. |
| .TP |
| \fB-L\fR |
| 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\&. |
| .TP |
| \fB-M\fR |
| Dump a list of loaded Static and Shared Modules\&. |
| .TP |
| \fB-S\fR |
| Show the settings as parsed from the config file (currently only shows the virtualhost settings)\&. |
| .TP |
| \fB-T\fR (Available in 2\&.3\&.8 and later) |
| Skip document root check at startup/restart\&. |
| .TP |
| \fB-t\fR |
| 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 \fIDUMP\fR_\fIVHOSTS \fRis also set, details of the virtual host configuration will be printed\&. If -D \fIDUMP\fR_\fIMODULES \fR is set, all loaded modules will be printed\&. If -D \fIDUMP\fR_\fICERTS \fR is set and mod_ssl is used, configured SSL certificates will be printed\&. If -D \fIDUMP\fR_\fICA\fR_\fI_CERTS \fR is set and mod_ssl is used, configured SSL CA certificates and configured directories containing SSL CA certificates will be printed\&. |
| .TP |
| \fB-v\fR |
| Print the version of \fBhttpd\fR, and then exit\&. |
| .TP |
| \fB-V\fR |
| Print the version and build parameters of \fBhttpd\fR, and then exit\&. |
| .TP |
| \fB-X\fR |
| Run httpd in debug mode\&. Only one worker will be started and the server will not detach from the console\&. |
| |
| .PP |
| The following arguments are available only on the Windows platform: |
| |
| |
| .TP |
| \fB-k install|config|uninstall\fR |
| Install Apache httpd as a Windows NT service; change startup options for the Apache httpd service; and uninstall the Apache httpd service\&. |
| .TP |
| \fB-n \fIname\fR\fR |
| The \fIname\fR of the Apache httpd service to signal\&. |
| .TP |
| \fB-w\fR |
| Keep the console window open on error so that the error message can be read\&. |
