You -also must not use '--enable-discard-path'. - -Running the FastCGI PHP module ------------------------------- - -There are two ways to run the resulting 'php' binary after the fastcgi -version has been built: - -1) Configure your web server to run the PHP binary itself. - -This is the simplest method, obviously you will have to configure your -web server appropriately. Some web servers may also not support this method, -or may not be as efficient. - -2) Run PHP separately from the web server. - -In this setup, PHP is started as a separate process entirely from the web -server. It will listen on a socket for new FastCGI requests, and deliver -PHP pages as appropriate. This is the recommended way of running PHP-FastCGI. -To run this way, you must start the PHP binary running by giving it an IP -and a port number to listen to on the command line, e.g.: - - ./php -b 127.0.0.1:8002 - -The above line is the recommended way of running FastCGI. You usually -want the FastCGI server to provide services to the localhost, not -everyone on the Internet. - -If your web server sits on a remote host, you can make FastCGI listen -on all interfaces: - - ./php -b :8002 - ./php -b "*:8002" - -Note that hostnames are not supported. - -You must also configure your web server to connect to the appropriate port -in order to talk to the PHP FastCGI process. - -The advantage of running PHP in this way is that it entirely separates the -web server and PHP process, so that one cannot disrupt the other. It also -allows PHP to be on an entirely separate machine from the web server if need -be, you could even have several web servers utilising the same running PHP -process if required! - - -Using FastCGI PHP with Apache -============================= - -First of all, you may well ask 'Why?'. After all, Apache already has mod_php. -However, there are advantages to running PHP with FastCGI. Separating the -PHP code from the web server removes 'bloat' from the main server, and should -improve the performance of non-PHP requests. Secondly, having one permanent -PHP process as opposed to one per apache process means that shared resources -like persistent database connections are used more efficiently. - -First of all, make sure that the FastCGI module is enabled. You should have -a line in your config like: - - LoadModule fastcgi_module /usr/lib/apache/2.0/mod_fastcgi.so - -Don't load mod_php, by the way. Make sure it is commented out! - - #LoadModule php5_module /usr/lib/apache/2.0/libphp5.so - -Now, we'll create a fcgi-bin directory, just like you would do with normal -CGI scripts. You'll need to create a directory somewhere to store your -FastCGI binaries. We'll use /space/fcgi-bin/ for this example. Remember to -copy the FastCGI-PHP binary in there. (named 'php-cgi') This sets up -php to run under mod_fastcgi as a dynamic server. - - ScriptAlias /fcgi-bin/ /space/fcgi-bin/ - <Location /fcgi-bin/> - Options ExecCGI - SetHandler fastcgi-script - </Location> - -To setup a specific static configuration for php, you have to use -the FastCgiServer configuration for mod_fastcgi. For this, do not -use the above configuration, but rather the following. -(see mod_fastcgi docs for more configuration information): - - Alias /fcgi-bin/ /space/fcgi-bin/ - FastCgiServer /path/to/php-cgi -processes 5 - -For either of the above configurations, we need to tell Apache to -use the FastCGI binary /fcgi-bin/php to deliver PHP pages. -All that is needed is: - - AddType application/x-httpd-fastphp .php - Action application/x-httpd-fastphp /fcgi-bin/php-cgi - -Now, if you restart Apache, php pages should now be delivered! - -Using FastCGI PHP with IIS or iPlanet -===================================== - -FastCGI server plugins are available at www.caraveo.com/fastcgi/ -Documentation on these are sparse. iPlanet is not very tested, -and no makefile exists yet for unix based iPlanet servers. - - -Security --------- - -Be sure to run the php binary as an appropriate userid. Also, firewall out -the port that PHP is listening on. In addition, you can set the environment -variable FCGI_WEB_SERVER_ADDRS to control who can connect to the FastCGI. -Set it to a comma separated list of IP addresses, e.g.: - -export FCGI_WEB_SERVER_ADDRS=199.170.183.28,199.170.183.71 - - -Tuning ------- - -There are a few tuning parameters that can be tweaked to control the -performance of FastCGI PHP. The following are environment variables that can -be set before running the PHP binary: - -PHP_FCGI_CHILDREN (default value: 0) - -This controls how many child processes the PHP process spawns. When the -fastcgi starts, it creates a number of child processes which handle one -page request at a time. Value 0 means that PHP willnot start additional -processes and main process will handle FastCGI requests by itself. Note that -this process may die (because of PHP_FCGI_MAX_REQUESTS) and it willnot -respawned automatic. Values 1 and above force PHP start additioanl processes -those will handle requests. The main process will restart children in case of -their death. So by default, you will be able to handle 1 concurrent PHP page -requests. Further requests will be queued. Increasing this number will allow -for better concurrency, especially if you have pages that take a significant -time to create, or supply a lot of data (e.g. downloading huge files via PHP). -On the other hand, having more processes running will use more RAM, and letting -too many PHP pages be generated concurrently will mean that each request will -be slow. - -PHP_FCGI_MAX_REQUESTS (default value: 500) - -This controls how many requests each child process will handle before -exitting. When one process exits, another will be created. This tuning is -necessary because several PHP functions are known to have memory leaks. If the -PHP processes were left around forever, they would be become very inefficient. diff --git a/sapi/cgi/cgi_main.c b/sapi/cgi/cgi_main.c deleted file mode 100644 index 45b6262fe9..0000000000 --- a/sapi/cgi/cgi_main.c +++ /dev/null @@ -1,1749 +0,0 @@ -/* - +----------------------------------------------------------------------+ - | PHP Version 5 | - +----------------------------------------------------------------------+ - | Copyright (c) 1997-2006 The PHP Group | - +----------------------------------------------------------------------+ - | This source file is subject to version 3.01 of the PHP license, | - | that is bundled with this package in the file LICENSE, and is | - | available through the world-wide-web at the following url: | - | http://www.php.net/license/3_01.txt | - | If you did not receive a copy of the PHP license and are unable to | - | obtain it through the world-wide-web, please send a note to | - | license@php.net so we can mail you a copy immediately. | - +----------------------------------------------------------------------+ - | Authors: Rasmus Lerdorf <rasmus@lerdorf.on.ca> | - | Stig Bakken <ssb@php.net> | - | Zeev Suraski <zeev@zend.com> | - | FastCGI: Ben Mansell <php@slimyhorror.com> | - | Shane Caraveo <shane@caraveo.com> | - | Dmitry Stogov <dmitry@zend.com> | - +----------------------------------------------------------------------+ -*/ - -/* $Id$ */ - -#include "php.h" -#include "php_globals.h" -#include "php_variables.h" -#include "zend_modules.h" - -#include "SAPI.h" - -#include <stdio.h> -#include "php.h" -#ifdef PHP_WIN32 -#include "win32/time.h" -#include "win32/signal.h" -#include <process.h> -#endif -#if HAVE_SYS_TIME_H -#include <sys/time.h> -#endif -#if HAVE_UNISTD_H -#include <unistd.h> -#endif -#if HAVE_SIGNAL_H -#include <signal.h> -#endif -#if HAVE_SETLOCALE -#include <locale.h> -#endif -#if HAVE_SYS_TYPES_H -#include <sys/types.h> -#endif -#if HAVE_SYS_WAIT_H -#include <sys/wait.h> -#endif -#include "zend.h" -#include "zend_extensions.h" -#include "php_ini.h" -#include "php_globals.h" -#include "php_main.h" -#include "fopen_wrappers.h" -#include "ext/standard/php_standard.h" -#ifdef PHP_WIN32 -#include <io.h> -#include <fcntl.h> -#include "win32/php_registry.h" -#endif - -#ifdef __riscos__ -#include <unixlib/local.h> -int __riscosify_control = __RISCOSIFY_STRICT_UNIX_SPECS;
