How to run Prestashop on nginx?

Question

Nginx

It costs Ubuntu 14.04 and Nginx 1.4.6 + php-frm. Wordpress successfully started with configs from the site. But with a simple problem, firstly, a site with a presto on a subdomain, and secondly, there are really no recommendations anywhere.
I created an A record for the subdomain and registered a separate server for the subdomain in nginx, which I found from people.

server {
   listen 80;
  server_name test.site.ru www.test.site.ru;
  charset utf8;
  # Прикрепляем файл со значениями из .htaccess

   index index.php index.html; # Letting nginx know which files to try when requesting a folder
 
 
    location = /favicon.ico {
        log_not_found off;      # PrestaShop by default does not provide a favicon.ico
        access_log off;         # Disable logging to prevent excessive log sizes
    }
 
 
     location = /robots.txt {
         auth_basic off;        # Whatever happens, always let bots know about your policy
         allow all;
         log_not_found off;     # Prevent excessive log size
         access_log off;
    }
 
    # Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
    location ~ /\. {
        deny all;
        access_log off;
        log_not_found off;
    }
 
    ##
    # Gzip Settings
    ##
 
    gzip on;
    gzip_disable "msie6";                                             # Do people still use Internet Explorer 6? In that case, disable gzip and hope for the best!
    gzip_vary on;                                                     # Also compress content with other MIME types than "text/html"
    gzip_types application/json text/css application/javascript;      # We only want to compress json, css and js. Compressing images and such isn't worth it
    gzip_proxied any;
    gzip_comp_level 6;                                                # Set desired compression ratio, higher is better compression, but slower
    gzip_buffers 16 8k;                                               # Gzip buffer size
    gzip_http_version 1.0;                                            # Compress every type of HTTP request

    try_files $uri $uri/ /index.php?$args;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_keep_conn on;
        include /etc/nginx/fastcgi_params;
        #fastcgi_pass 127.0.0.1:9000;                    # When using TCP
        fastcgi_pass unix:/var/run/php/php-fpm.sock;   # When using unix sockets
    }
 
}

I go to the subdomain and get 502 Bad Gateway. Tell me what could be the problem?!

Answer 1

See what you have in /var/log/nginx/error.log. There will be a description of the error. You fix it further until you get a working version.
