Lighttpd

= Setting up PHP with Lighttpd =
Introduction

Lighttpd supports PHP through both CGI and FastCGI. As the name suggests, FastCGI is preferable.

Performance

In all our tests it has shown better performance than Apache 1.3.x + mod_php4. See http://www.lighttpd.net/benchmark/ for the results.

Does it support opcode cachers like APC, TurckMM, XCache and friends?

YES! Even if their docs say they do not work in CGI. Under lighttpd, PHP is usually run as FastCGI which supports those opcode cachers like mod_php4 in Apache.

• http://pecl.php.net/apc
• http://eaccelerator.net/ (Successor of Turck mmCache)
• [/xcache XCache], [/xcache/wiki/GettingSource Installing XCache] (new, well tested, running with FastCGI)

= Installation =

=== Windows ===
First you need to install [http://www.kevinworthington.com:8181/?cat=20 Lighttpd for Windows]. Then you need to edit C:\lighttpd\etc\lighttpd.conf, uncomment the "mod_cgi" line and add this line: {{{
cgi.assign = ( ".php" => "c:/php/php-cgi.exe" )
}}}
Be careful, there cannot be any space in the path to PHP-CGI in the above snippet. Save lighttpd.conf and restart lighttpd. Open your browser and go to [http://localhost/ http://localhost/], you should have a welcome page. You can put your PHP files in C:\lighttpd\htdocs - To test PHP, just create a file named index.php, save it in the Lighttpd root directory (C:\lighttpd\htdocs) and paste this content into this file: {{{
phpinfo();
?>
}}}
Accessing [http://localhost/ http://localhost/], you should get a page that lists all PHP variables and information.
Please note that FastCGI doesn't work on Windows at this time. Good luck!

=== Unix Systems ===

'''Startingpoint:''' Lighttpd is already [wiki:TutorialInstallation installed and working]

First of all you need a PHP which is providing FastCGI support. Depending on your
distribution you might already have it: === ArchLinux ===
Read http://wiki.archlinux.org/index.php/Fastcgi_and_lighttpd

=== FreeBSD === {{{
#!ShellExample
$ cd /usr/ports/lang/php5

1. make install clean
   }}}
   Be sure to check the "use as FastCGI" option in the configuration screen. If you don't see the configuration screen, you're either using an old version of ports tree, or need to execute "make config". If you're using PHP 4 or an early version of PHP 5, you may have to use www/php4-cgi or a similar port instead of the new master port.

=== PC-BSD ===
Download the [http://www.pbidir.com/search.php?str=lighttpd self-executable setup wizard], double-click the file, and follow the instructions of the setup wizard. You will have a "www" directory under your home directory to put your web pages. You'll have the possibility to launch lighttpd at system startup automatically, and to support one or several users. Once you're done, just open http://localhost/ in your favorite browser and you should see the welcome screen.

=== Gentoo ===
Make sure the USE flag 'cgi' is enabled. {{{
#!ShellExample
$ emerge -av dev-lang/php
}}}
If it is not, add the USE flag your /etc/make.conf or just to the dev-lang/php ebuild. {{{
#!ShellExample

1. echo dev-lang/php cgi >> /etc/portage/package.use
   }}}

As of 21/09/06, a test ebuild of Xcache is also available for gentoo on http://bugs.gentoo.org/show_bug.cgi?id=148417 === Debian / Ubuntu ===
Debian/Ubuntu provides a fastcgi enabled version. {{{
#!ShellExample

1. apt-get install php4-cgi
   }}}
   If you're using php5-cgi, all you need is change your "bin-path" at your [http://trac.lighttpd.net/trac/wiki/TutorialLighttpdAndPHP#Configuration configuration] (Debian uses /usr/bin/php4-cgi as default). === DragonFlyBSD ===
   DragonFlyBSD uses pkgsrc to build it's packages. If you don't want IPV6 you need to use the deprecated USE_IPV6=NO. {{{
   #!ShellExample
2. cd /usr/pkgsrc/www/php4
3. bmake PKG_OPTIONS.php="fastcgi ssl" PKG_DEFAULT_OPTIONS="fastcgi ssl" install clean
   }}} === Others ===
   Download a source tar-ball from http://www.php.net/ and configure it with at least this settings: {{{
   #!ShellExample
   $ ./configure \
   --enable-fastcgi \
   --enable-discard-path \
   --enable-force-redirect
   }}}
   If you want to have the same PHP as you are using in a mod_php configuration somewhere else call {{{
   #!php
   
   }}} * copy the configure options from the output of the script * remove the ``--with-apxs`` and ``--with-apxs2`` options * add the three options from above.
   Build PHP now by callings ``make`` and ``make install`` and see if you can find a php binary which is responding: {{{
   #!ShellExample
   $ php -v
   PHP 5.0.3 (cgi-fcgi) (built: Dec 21 2004 12:59:18)
   Copyright (c) 1997-2004 The PHP Group
   Zend Engine v2.0.3, Copyright (c) 1998-2004 Zend Technologies
   with eAccelerator v0.9.3, Copyright (c) 2004-2005 eAccelerator, by eAccelerator
   }}}
   or something like this. The ``(cgi-fcgi)`` is the important part. The binary might also be called ``php-cgi``.
   so do something like php-cgi -v to see the (cgi-fcgi) banner. {{{
   #!ShellExample
   $ php-cgi -v
   PHP 4.4.2 (cgi-fcgi) (built: Jul 21 2006 15:45:58)
   Copyright (c) 1997-2006 The PHP Group
   Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies
   }}}

If you still can't find it follow this hint: {{{
#!ShellExample
$ ls sapi/cgi/php
}}}
Configuration
Add this line:

{{{
cgi.fix_pathinfo = 1
}}}

to your ``php.ini``.

And make sure mod_fastcgi is loaded in your ``lighttpd.conf``: {{{
server.modules = (
"mod_fastcgi",
)
}}}

Then add this basic section to the same file: {{{
fastcgi.server = ( ".php" => ((
"bin-path" => "/path/to/php-cgi",
"socket" => "/tmp/php.socket"
)))
}}}

A little bit more advance is this setting which tries the tune some more options. If you need PATH_INFO the broken-scriptfilename is
for you. {{{
fastcgi.server = ( ".php" => ((
"bin-path" => "/path/to/php-cgi",
"socket" => "/tmp/php.socket",
"max-procs" => 2,
"bin-environment" => (
"PHP_FCGI_CHILDREN" => "16",
"PHP_FCGI_MAX_REQUESTS" => "10000"
),
"bin-copy-environment" => (
"PATH", "SHELL", "USER"
),
"broken-scriptfilename" => "enable"
)))
}}}

It is important to set '''"max-procs"''' to 1 if you're using any php opcode cacher, unless you know what you're doing. Increase PHP_FCGI_CHILDREN if you want more childs serving the request.

Please read the configuration section for more background * [wiki:Docs:Configuration] * [wiki:Docs:ModFastCGI]
and use
http://trac.lighttpd.net/trac/browser/tags/lighttpd-1.4.11/doc/lighttpd.conf as starting point for the configuration.

Per directory PHP Config
If you're used to use Apache .htaccess files to set PHP options for each directory, see HowToPhpHtaccess :

''When using a cgi version of php (plain old cgi or fast-cgi) apache can't pass
any php settings from htaccess files it parses. This can be solved by giving
each user it's own php.ini file, but I didn't like that solution.
This extension parses these configuration files (in most cases .htaccess) and
changes the settings. It will search all directories for a configuration file
from the docroot until the directory where the request scripts is found. A cache
is implemented to minimize the performance impact.''
