<h3>Summary</h3>
<p>Any program assigned to the handler <code>fcgid-script</code> is processed
using the FastCGI protocol; <code class="module"><a href="../mod/mod_fcgid.html">mod_fcgid</a></code> starts a sufficient
number instances of the program to handle concurrent requests, and these
programs remain running to handle further incoming requests. This is
significantly faster than using the default <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code> or
<code class="module"><a href="../mod/mod_cgid.html">mod_cgid</a></code> modules to launch the program upon each request.
However, the programs invoked by <code class="module"><a href="../mod/mod_fcgid.html">mod_fcgid</a></code> continue to
consume resources, so the administrator must weigh the impact of invoking
a particular program once per request against the resources required to
leave a sufficient number of instances running continuously.</p>
<p>The pool of fcgid-invoked programs is shared between all httpd workers.
Configuration directives below let the administrator tune the number of
instances of the program that will run concurrently.</p>
<p>Specific executables are assigned this handler either by having a name
containing an extension defined by the
<code class="directive"><a href="../mod/mod_mime.html#addhandler">AddHandler</a></code> directive, or with an
override using the <code class="directive"><a href="../mod/mod_mime.html#sethandler">SetHandler</a></code>
directive (e.g., for all files in a specific directory such as cgi-bin).</p>
<p>Some changes have been made in the ASF release of mod_fcgid which
can affect existing configurations. All documentation refers to new
names for the directives. (The old names still work but are now
deprecated.) Please read the <a href="#upgrade">Upgrade Notes</a> for
details.</p>
<p>For an introduction to using CGI scripts with Apache, see
the generic tutorial on <a href="../howto/cgi.html">Dynamic Content
With CGI</a>.</p>

<h2><a name="upgrade" id="upgrade">Upgrade Notes</a></h2>
<p>The following changes have been made in the ASF release of mod_fcgid
and should be considered when upgrading from the original version by
Ryan Pan (Pan Qingfeng).</p>
<ul>
<li>All directives have been renamed in order to use a common prefix "Fcgid".
Underscores in directive names have been eliminated in favor of
CamelCase. The old directive names will still work but are deprecated.
To fix your configuration you can use the sed script build/fixconf.sed.
The following table contains old and new directive names:

<h2><a name="examples" id="examples">Examples</a></h2>
<div class="note"><h3>Note</h3>
<p>The examples assume that mod_fcgid and other necessary
modules are loaded into the server already, either built-in or
via the <code class="directive"><a href="../mod/mod_so.html#loadmodule">LoadModule</a></code>
directive.</p>
<p>Additionally, the example configurations provide full access
to the applications using access control directives which work
with Apache 2.0 and 2.2. These directives are not appropriate
for all environments, and they do not work for development
levels of Apache HTTP Server (Subversion trunk).</p>
</div>
<p>The first example is a very simple Perl FastCGI application,
and its configuration directives. This is typical for FastCGI
applications which require no special configuration.</p>
<div class="example"><h3>Perl FastCGI application - /usr/local/apache/fcgi-bin/foo.pl</h3><p><code>
#!/usr/bin/perl<br />
use CGI::Fast;<br />
<br />
while (my $q = CGI::Fast->new) {<br />
<span class="indent">
print("Content-Type: text/plain\n\n");<br />
foreach $var (sort(keys(%ENV))) {<br />
<span class="indent">
$val = $ENV{$var};<br />
$val =~ s|\n|\\n|g;<br />
$val =~ s|"|\\"|g;<br />
print "${var}=\"${val}\"\n";<br />
</span>
}<br />
</span>
}<br />
</code></p></div>
<div class="example"><h3>Configuration directives</h3><p><code>
<Directory /usr/local/apache/fcgi-bin/><br />
<span class="indent">
SetHandler fcgid-script<br />
Options +ExecCGI<br />
<br />
# Customize the next two directives for your requirements.<br />
Order allow,deny<br />
Allow from all<br />
</span>
</Directory><br />
</code></p></div>
<p>PHP applications are usually configured using the
<code class="directive"><a href="#fcgidwrapper">FcgidWrapper</a></code> directive
and a corresponding wrapper script. The wrapper script can be
an appropriate place to define any environment variables required
by the application, such as <code>PHP_FCGI_MAX_REQUESTS</code>
or anything else. (Environment variables can also be set with
<code class="directive"><a href="#fcgidinitialenv">FcgidInitialEnv</a></code>,
but they then apply to all applications.)</p>
<p>Here is an example that uses a wrapper script to invoke PHP:</p>
<div class="example"><h3>PHP application - /usr/local/phpapp/phpinfo.php</h3><p><code>
<?php<br />
<span class="indent">
phpinfo();<br />
</span>
?><br />
</code></p></div>
<div class="example"><h3>Configuration directives</h3><p><code>
# FcgidMaxRequestsPerProcess should be <= PHP_FCGI_MAX_REQUESTS<br />
# The example PHP wrapper script overrides the default PHP setting.<br />
FcgidMaxRequestsPerProcess 10000<br />
<br />
# Uncomment the following line if cgi.fix_pathinfo is set to 1 in<br />
# php.ini:<br />
# FcgidFixPathinfo 1<br />
<br />
Alias /phpapp/ /usr/local/phpapp/<br />
<Location /phpapp/><br />
<span class="indent">
AddHandler fcgid-script .php<br />
Options +ExecCGI<br />
FcgidWrapper /usr/local/bin/php-wrapper .php<br />
<br />
# Customize the next two directives for your requirements.<br />
Order allow,deny<br />
Allow from all<br />
</span>
</Location><br />
</code></p></div>
<div class="example"><h3>PHP wrapper script - /usr/local/bin/php-wrapper</h3><p><code>
#!/bin/sh<br />
# Set desired PHP_FCGI_* environment variables.<br />
# Example:<br />
# PHP FastCGI processes exit after 500 requests by default.<br />
PHP_FCGI_MAX_REQUESTS=10000<br />
export PHP_FCGI_MAX_REQUESTS<br />
<br />
# Replace with the path to your FastCGI-enabled PHP executable<br />
exec /usr/local/bin/php-cgi<br />
</code></p></div>
<div class="note"><h3>Special PHP considerations</h3>
<p>By default, PHP FastCGI processes exit after handling 500
requests, and they may exit after this module has already
connected to the application and sent the next request. When that
occurs, an error will be logged and <code>500 Internal Server
Error</code> will be returned to the client. This PHP behavior
can be disabled by setting <code>PHP_FCGI_MAX_REQUESTS</code> to
0, but that can be a problem if the PHP application leaks
resources. Alternatively, <code>PHP_FCGI_MAX_REQUESTS</code> can
be set to a much higher value than the default to reduce the
frequency of this problem.
<code class="directive"><a href="#fcgidmaxrequestsperprocess">FcgidMaxRequestsPerProcess</a></code>
can be set to a value less than or equal to
<code>PHP_FCGI_MAX_REQUESTS</code> to resolve the problem.</p>
<p>PHP child process management (<code>PHP_FCGI_CHILDREN</code>)
should always be disabled with mod_fcgid, which will only route
one request at a time to application processes it has spawned;
thus, any child processes created by PHP will not be used
effectively. (Additionally, the PHP child processes may not be
terminated properly.) By default, and with the environment
variable setting <code>PHP_FCGI_CHILDREN=0</code>, PHP child
process management is disabled.</p>
<p>The popular APC opcode cache for PHP cannot share a cache
between PHP FastCGI processes unless PHP manages the child
processes. Thus, the effectiveness of the cache is limited with
mod_fcgid; concurrent PHP requests will use different opcode
caches.</p>

<p>Several of the directives control processing for a <em>process
class</em>. A process class is the set of processes which were started
with the same executable file and share certain other characteristics such
as virtual host and identity. Two commands which are links to or otherwise
refer to the same executable file share the same process class.</p>
<div class="note"><h3>Note</h3>
<p>Certain settings or other concepts that depend on the virtual host,
such as <code class="directive"><a href="#fcgidinitialenv">FcgidInitialEnv</a></code>
or process classes, distinguish between virtual hosts only if they
have distinct server names. (See the <code class="directive">ServerName</code>
documentation for more information.) In the case of
<code class="directive"><a href="#fcgidinitialenv">FcgidInitialEnv</a></code>, if two
virtual hosts have the same server name but different environments as
defined by

<p>This directive specifies the name of a request header which
will be passed to the FastCGI application as an environment
variable. The name of the environment variable is derived from
the value specified on this directive, as discussed below:</p>
<p>The legacy behavior is to use the value specified on this directive
as the environment variable name, converting hyphens to underscores.
No case conversion is performed.</p>
<p>Beginning with release 2.3.6, an additional environment variable
is created. The value specified on this directive is converted to
upper case, prefixed with <code>HTTP_</code>, and hyphens are
converted to underscores.</p>
<div class="note"><h3>Note</h3>
<p>Most request headers are already available to the application
as environment variables, and generally are prefixed with
<code>HTTP_</code>. (Notable exceptions are <code>Content-type</code>
and <code>Content-length</code>, which do not have the
<code>HTTP_</code> prefix.) Thus, this directive is only required
for request headers that are purposefully omitted, such as
<code>Authorization</code> and <code>Proxy-Authorization</code>.
Only pass these request headers if absolutely required.</p>

<p>A process activity score is maintained for each FastCGI application;
the score is used to control the rate of spawning in order to avoid
placing too much load on the system, particularly for applications that
are repeatedly exiting abnormally.</p>
<p>The value of <code class="directive"><a href="#fcgidspawnscore">FcgidSpawnScore</a></code>
is added to the score for every spawned application process. The value of
<code class="directive"><a href="#fcgidterminationscore">FcgidTerminationScore</a></code> is added
to the score for every terminated application process. The value of
<code class="directive"><a href="#fcgidtimescore">FcgidTimeScore</a></code> is subtracted
from the score every second.</p>
<p>When the current score is higher than the value of
<code class="directive">FcgidSpawnScoreUpLimit</code>, no additional application
processes will be spawned; subsequent requests must wait until an existing
process is free or until the score decreases below the limit.</p>

simply increase the limit, as that would only delay the amount of time
