|
|
<H2>Invoking Apache</H2>
|
|
|
|
On Unix, the <CODE>httpd</CODE> program is usually run as a daemon
|
|
which executes continuously, handling requests. It is possible to
|
|
invoke Apache by the Internet daemon <CODE>inetd</CODE> each time a
|
|
connection to the HTTP service is made (use the <A
|
|
HREF="mod/core.html#servertype">ServerType</A> directive) but this is
|
|
not recommended.
|
|
|
|
<P>
|
|
|
|
On Windows, Apache is normally run as a service on Windows NT, or as a
|
|
console application on Windows 95. See also <A
|
|
HREF="windows.html#run">running Apache for Windows</A>.
|
|
|
|
<H2>Command line options</H2>
|
|
The following options are recognized on the httpd command line:
|
|
<DL>
|
|
<DT><CODE>-d</CODE> <EM>serverroot</EM>
|
|
<DD>Set the initial value for the
|
|
<A HREF="mod/core.html#serverroot">ServerRoot</A> variable to
|
|
<EM>serverroot</EM>. This can be overridden by the ServerRoot command
|
|
in the configuration file. The default is
|
|
<CODE>/usr/local/apache</CODE> on Unix, <CODE>/apache</CODE> on
|
|
Windows and <CODE>/os2httpd</CODE> on OS/2.
|
|
|
|
<DT><CODE>-D</CODE> <EM>name</EM>
|
|
<DD>Define a name for use in in
|
|
<A HREF="mod/core.html#ifdefine">IfDefine</A> directives.
|
|
This option can be used to optionally enable certain functionality in the
|
|
configuration file, or to use a common configuration for
|
|
several independent hosts, where host specific information is enclosed in
|
|
<IfDefine> sections.
|
|
|
|
<DT><CODE>-f</CODE> <EM>config</EM>
|
|
<DD>Execute the commands in the file <EM>config</EM> on startup. If
|
|
<EM>config</EM> does not begin with a <CODE>/</CODE>, then it is taken to be a
|
|
path relative to the <A HREF="mod/core.html#serverroot">ServerRoot</A>. The
|
|
default is <CODE>conf/httpd.conf</CODE>.
|
|
|
|
<DT><CODE>-C</CODE> <EM>"directive"</EM>
|
|
<DD>Process the given apache "directive" (just as if it had been part of a
|
|
configuration file) <STRONG>before</STRONG> actually reading the regular configuration files.
|
|
|
|
<DT><CODE>-c</CODE> <EM>"directive"</EM>
|
|
<DD>Process the given apache "directive" <STRONG>after</STRONG> reading
|
|
all the regular configuration files.
|
|
|
|
<DT><CODE>-X</CODE>
|
|
<DD>Run in single-process mode, for internal debugging purposes only; the
|
|
daemon does not detach from the terminal or fork any children. Do <EM>NOT</EM>
|
|
use this mode to provide ordinary web service.
|
|
|
|
<DT><CODE>-v</CODE>
|
|
<DD>Print the version of httpd and its build date, and then exit.
|
|
|
|
<DT><A NAME="version"><CODE>-V</CODE></A>
|
|
<DD>Print the base version of httpd, its
|
|
build date, and a list of compile time settings which influence the
|
|
behavior and performance of the apache server (<EM>e.g.</EM>,
|
|
<SAMP>-DUSE_MMAP_FILES</SAMP>),
|
|
then exit.
|
|
|
|
<DT><A NAME="help"><CODE>-L</CODE></A>
|
|
<DD>
|
|
|
|
Give a list of directives together with expected arguments and places
|
|
where the directive is valid, then exit. (Apache 1.3.4 and
|
|
later. Earlier versions used -l instead).
|
|
|
|
|
|
<DT><CODE>-l</CODE></A>
|
|
<DD>
|
|
|
|
Give a list of all modules compiled into the server, then exit.
|
|
(Apache 1.3.4 and later. Earlier versions used -h instead).<br>
|
|
|
|
Give a list of directives together with expected arguments and places
|
|
where the directive is valid, then exit. (Apache 1.2 to 1.3.3. Later
|
|
versions use -L instead).
|
|
|
|
|
|
|
|
<DT><CODE>-h</CODE>
|
|
<DD>
|
|
|
|
Print a list of the httpd options, then exit. (Apache 1.3.4 and
|
|
later. Earlier versions used -? instead).<br>
|
|
|
|
Give a list of all modules compiled into the server, then exit. (Up to
|
|
Apache 1.3.3. Later versions use -l instead).<br>
|
|
|
|
|
|
<DT><CODE>-S</CODE>
|
|
<DD>Show the settings as parsed from the config file (currently only
|
|
shows a breakdown of the vhost settings) but do not start the
|
|
server. (Up to Apache 1.3.3, this option also started the server).
|
|
|
|
<DT><CODE>-t</CODE>
|
|
<DD>Test the configuration file syntax (<EM>i.e.</EM>, read all configuration files
|
|
and interpret them) but do not start the server. If the configuration contains
|
|
errors, display an error message and exit with a non-zero exit status,
|
|
otherwise display "Syntax OK" and terminate with a zero exit status. This
|
|
command checks to see if all DocumentRoot entries exist and are directories.
|
|
For sites with many vhosts, this is expensive; consider the <CODE>-T</CODE>
|
|
command instead.
|
|
|
|
<DT><CODE>-T</CODE>
|
|
<DD>Test the configuration file syntax (<EM>i.e.</EM>, read all configuration files
|
|
and interpret them) but do not start the server. If the configuration contains
|
|
errors, display an error message and exit with a non-zero exit status,
|
|
otherwise display "Syntax OK" and terminate with a zero exit status. This
|
|
command does not perform any checking of the DocumentRoot entries.
|
|
|
|
<DT><CODE>-k</CODE> <EM>option</EM>
|
|
<DD>Windows only: signal Apache to restart or shutdown. <EM>option</EM>
|
|
is one of "shutdown" or "restart". (Apache 1.3.3 and later).
|
|
|
|
<DT><CODE>-?</CODE>
|
|
<DD>Print a list of the httpd options, and then exit (up to Apache
|
|
1.3.3. Later version use -h instead).
