Have Nginx As Backend

msk19994 · Post by **msk19994** » Mon Jul 25, 2016 5:03 am

Hey Guys
I wanted to inquire if there was a way rather than having apache as backend and nginx as front end. We can have full nginx ie backend as well as frontend, Currently i am using phpfcgid but the script that i am running requires some modules to run as nginx rather than apache.
It would be great if someone could help me out here
Thanks

In this thread i inquired to add some additional code to nginx http://forum.vestacp.com/viewtopic.php?f=11&t=12165
after doing that the nginx is working no errors but the code itself is not working

This is what i am trying to accomplish

the table plugin_reward_ppd_complete_download is empty and not updating

Below is the log download file code

Code: Select all

<?php

// used for NGINX callback on PPD download finish. See the admin area, reward
// plugin settings for more information.
// global includes
define('CLI_MODE', true);
require_once('../../../core/includes/master.inc.php');

// log callback data
log::setContext('plugin_reward_nginx_complete_download');
log::breakInLogFile();
log::info('Data received: ' . http_build_query($_REQUEST));

// ignore if not OK response
//if ((!isset($_REQUEST['status'])) || ((strtoupper($_REQUEST['status']) != 'OK') && (strtoupper($_REQUEST['status']) != '')))

{
	//log::info('No status found or status not \'OK\'');
    //exit;
}

// prepare response for inserting
$downloadTokenExp = explode('download_token=', $_REQUEST['request_uri']);
$downloadToken    = current(explode('&', $downloadTokenExp[1]));
if (!strlen($downloadToken))
{
	log::info('No download token found.');
    exit;
}

// initial variables
$payPPD       = false;

// load file details
$fileSize   = -1;

$fileDetail = $db->getRow('SELECT file.fileSize, file.userId, file.id FROM file LEFT JOIN download_token ON file.id = download_token.file_id WHERE download_token.token=' . $db->quote($downloadToken) . ' LIMIT 1');
if (!$fileDetail)

	log::info('Could not load download token details using '.$downloadToken);
	exit;
}

// if total bytes sent equals file size pay PPD

It's not nginx your backend, nginx still your front-end. Your backend here - php-fpm or something like this.

Nginx can't be backend by yourself for dynamic content (can if you server static content only: html/files/etc).

Like you had suggested i have installed nginx + php-fpm
Now i am having a similar issue when adding code to the nginx file

Code: Select all

server {
    listen      158.69.223.8:80;
    server_name picu.pk www.picu.pk;

		    location ~ \.php$ {

    location / {
		if (!-e $request_filename) {
			rewrite ^/(.*) /index.php?_page_url=$1 last;
		}
    }

  location /files/ {
        internal;
    }


    # these locations would be hidden by .htaccess normally
    location /core/logs/ {
        deny all;
    }
    }

    error_page  403 /error/404.html;

    include     /etc/nginx/conf.d/webmail.inc*;

    include     /home/admin/conf/web/nginx.hostingrill.co.conf*;
}

Now for the site to work i had to add some codes
I added

Code: Select all

  location /files/ {
        internal;
    }

and others but now when i need to add this new module and replace this old code

i have to add

Code: Select all

location /files {
    root /home/admin/web/hostingrill.co/public_html;
    post_action @afterdownload;
    internal;
}

location @afterdownload {
    proxy_pass http://hostingrill.co/plugins/rewards/site/_log_download.php?request_uri=$request_uri&remote_addr=$remote_addr&body_bytes_sent=$body_bytes_sent&status=$request_completion&content_length=$content_length&http_user_agent=$http_user_agent&http_referer=$http_referer&args=$args;
    internal;
}

after replacing it says
when added command

Code: Select all

nginx -t

nginx: [emerg] named location "@afterdownload" can be on the server level only in /home/admin/conf/web/nginx.conf:93
nginx: configuration file /etc/nginx/nginx.conf test failed

Code: Select all

 proxy_pass http://hostingrill.co/plugins/rewards/site/_log_download.php?request_uri=$request_uri&remote_addr=$remote_addr&body_bytes_sent=$body_bytes_sent&status=$request_completion&content_length=$content_length&http_user_agent=$http_user_agent&http_referer=$http_referer&args=$args;

This proxy_pass just wrong.
Let php-fpm do the thing.. try to use default template and change for yourself just in case it's needed.
