Пункт 63. Manual Page: httpd
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 apache2ctl on Unix-based systems or as a service on Windows NT,
2000 and XP and as
a console application on Windows 9x and ME.
Synopsis
httpd [ -d

[ -e level ] [ -E

[ -k start|restart|graceful|stop|graceful-stop ]
[ -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 ]
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
/usr/local/apache2 .
-
-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/apache2.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.
