apache2 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, apache2 should not be invoked directly, but rather should be invoked
via /etc/init.d/apache2 or apache2ctl. The default Debian configuration
requires environment variables that are defined in /etc/apache2/envvars and
are not available if apache2 is started directly. However, apache2ctl can be
used to pass arbitrary arguments to apache2.
The full documentation is available in the apache2-doc package or at
. Information about Debian specific changes
and configuration can be found in /usr/share/doc/apache2/README.Debian.gz .
- -d serverroot
- Set the initial value for the ServerRoot directive to serverroot.
This can be overridden by the ServerRoot directive in the configuration
- -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 /etc/apache2/apache2.conf.
- -k start|restart|graceful|stop|graceful-stop
- Signals apache2 to start, restart, or stop. See Stopping Apache for more
- -C directive
- Process the configuration directive before reading config
- -c directive
- Process the configuration directive after reading config
- -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.
- -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.
- -R directory
- When the server is compiled using the SHARED_CORE rule, this specifies the
directory for the shared object files.
- Output a short summary of available command line options.
- Output a list of modules compiled into the server. This will not
list dynamically loaded modules included using the LoadModule
- Output a list of directives together with expected arguments and places
where the directive is valid.
- Dump a list of loaded Static and Shared Modules.
- Show the settings as parsed from the config file (currently only shows the
- 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.
- Print the version of apache2, and then exit.
- Print the version and build parameters of apache2, and then exit.
- Run apache2 in debug mode. Only one worker will be started and the server
will not detach from the console.
