## SUMMARY
       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  pro‐
       cesses 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.

## DOCUMENTATION
       The   full   documentation   is   available   in    the    apache2-doc    package    or    at
       <http://httpd.apache.org/docs/2.2/>  . Information about Debian specific changes and configura‐
       tion can be found in /usr/share/doc/apache2/README.Debian.gz .

## OPTIONS
       -d _serverroot_
              Set the initial value for the ServerRoot directive to _serverroot_. This can be overrid‐
              den by the ServerRoot directive in the configuration file.

       -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 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 con‐
              figuration 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 in‐
              creasing 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.

       -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 together with expected arguments and places where the  di‐
              rective is valid.

       -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     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 apache2, and then exit.

       -V     Print the version and build parameters of apache2, and then exit.

       -X     Run apache2 in debug mode. Only one worker will be started and the server will not de‐
              tach from the console.
