Multiple simultaneous requests to PHP script with NGINX

Question

I have a webserver running NGINX & PHP, with a very basic multi client test.

<?php
    if(isset($_GET['query'])) {
        echo "HELLO MY NAME IS WEBSERVER";
    }
    if(isset($_GET['sleep'])) {
        sleep(10);
    }
?>

If I run http://servername.com/index.php?query, I get an instant response.

If I run ?sleep then ?query together, ?query appears to be queued till ?sleep is complete.

This happens across multiple clients. Client A can request ?sleep, which will affect Client B's ?query request. Client B is a completely different machine.

Is there any method of tweaking php.ini or my nginx config to allow a separate php worker process to spawn (or something along those lines?)

Edit: For a little background, here's my config.

nginx.conf:

    location ~ \.php$ {
            fastcgi_pass   127.0.0.1:9123;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
    }

fastgci_params:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REQUEST_SCHEME     $scheme;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

php execution (runphp.bat):

set PATH=%cd%\php;%PATH%
start %cd%\php\php-cgi.exe -b 127.0.0.1:9123

edit 2: Ok, so it appears I need PHP-FPM, which is not available on windows:

It is important to note that FPM is not built with the windows binaries.  Many of the guides you may find online rely on php-cgi.exe.  Unfortunately they call it FPM but this is incorrect!

The executable php-cgi.exe that is bundled with the windows binaries is a FastCGI interface but it is *not* FPM (Fastcgi Process Manager).  php-cgi.exe does not have multi-threading or concurrent request support, nor support for any of the FPM configuration options.

So, as a workaround, I'm trying the multiple php servers / processes approach:

upstream php {
    server  127.0.0.1:9000;
    server  127.0.0.1:9001;
    server  127.0.0.1:9002;
    server  127.0.0.1:9003;
}

location ~ \.php$ {
    fastcgi_pass   php;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

However, NGINX will not start at all in this configuration. It doesn't seem to want to accept any "upstream php {}"

Any ideas?

Thanks

Answer 1

As per the edits, I figured PHP-FPM isn't available in Windows. However, this can be bypassed by spawning multiple PHP processes on different ports, and configuring NGINX to load balance across them.

My "RunPHP.bat" script:

set PATH=%cd%\php;%PATH%
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9100
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9101
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9102
runhiddenconsole.exe %cd%\php\php-cgi.exe -b 127.0.0.1:9103

My nginx.conf (php bits only):

http {

    upstream php_farm {
        server 127.0.0.1:9100 weight=1 max_fails=1 fail_timeout=1s;
        server 127.0.0.1:9101 weight=1 max_fails=1 fail_timeout=1s;
        server 127.0.0.1:9102 weight=1 max_fails=1 fail_timeout=1s;
        server 127.0.0.1:9103 weight=1 max_fails=1 fail_timeout=1s;
    }

    server {
        location ~ \.php$ {
                fastcgi_pass   php_farm;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                include        fastcgi_params;

    }

}
