SYNOPSIS¶
httpd [ -d serverroot ] [ -f config ] [ -C directive ] [ -c directive ] [ -D parameter ] [ -e level ] [ -E file ] [ -k start|restart|graceful|stop|graceful-stop ] [ -R directory ] [ -h ] [ -l ] [ -L ] [ -S ] [ -t ] [ -v ] [ -V ] [ -X ] [ -M ] [ -T ]
On Windows systems, the following additional arguments are available:
httpd [ -k install|config|uninstall ] [ -n name ] [ -w ]
SUMMARY¶
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.
OPTIONS¶
- -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 /etc/httpd.
- -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 httpd 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. Also can be used to set certain less-common startup parameters including -DNO_DETACH (prevent the parent from forking) and -DFOREGROUND (prevent the parent from calling setsid() et al).
- -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.
- -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 provided by static modules, together with expected arguments and places where the directive is valid. Directives provided by shared modules are not listed.
- -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 (Available in 2.3.8 and later)
- Skip document root check at startup/restart.
- -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 httpd as a Windows NT service; change startup options for the Apache httpd service; and uninstall the Apache httpd service.
- -n name
- The name of the Apache httpd service to signal.
- -w
- Keep the console window open on error so that the error message can be read.
