在一个专用服务器ubuntu上运行多个nginx

Question

Is it possible to run multiple NGINX on a single Dedicated server? I have a dedicated server with 256gb of ram, and I am running multiple PHP scripts on it but it's getting hangs because of memory used with PHP. when I check

free -m

it's not even using 1% of memory.

So, I am guessing its has some to do with NGINX.

Can I install multiple NGINX on this server and use them like

 5.5.5.5:8080,  5.5.5.5:8081,  5.5.5.5:8082

I have already allocated 20 GB memory to PHP, but still not working Properly.

Reason :- NGINX gives 504 Gateway Time-out

I got my Ubuntu / PHP / Nginx server set this way (it actually also runs some Node.js servers in parallel). Here is a configuration example which works fine on a AWS EC2 medium instance (m3).

upstream xxx {
#   server unix:/var/run/php5-fpm.sock;
    server 127.0.0.1:9000 max_fails=0 fail_timeout=10s weight=1;
    ip_hash;
    keepalive 512;
}

server {
    listen 80;
    listen 8080;
    listen 443 ssl;
    #listen [::]:80 ipv6only=on;

    server_name xxx.mydomain.io yyy.mydomain.io;
    if ( $http_x_forwarded_proto = 'http' ) {
        return 301 https://$server_name$request_uri;
    }

    root /home/ubuntu/www/xxxroot;
    index index.php;

    location / {
        try_files $uri $uri/ /index.php;
    }


    location ~ ^/(status|ping)$ {
        access_log off;
        allow 127.0.0.1;
        #allow 1.2.3.4#your-ip;
        #deny all;
        include fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;

        fastcgi_pass adn;
        #fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
#fastcgi_param SCRIPT_FILENAME /xxxroot/$fastcgi_script_name;
        fastcgi_param SCRIPT_FILENAME $request_filename;
#fastcgi_param DOCUMENT_ROOT /home/ubuntu/www/xxxroot;
        # send bad requests to 404
        #fastcgi_intercept_errors on;
        include fastcgi_params;
    }

    location ~ /\.ht {
            deny all;
    }

}

Hope it helps,
