Using vBulletin with NGINX 
As of vBulletin 5.0.4, we support the popular NGINX Webserver. This is frequently used on Virtual Private Servers and Dedicated servers. If you are using NGINX, you need additional configuration for vBulletin. We provide this in a nginx.vhost file. This file is located in the do_not_upload folder of your vBulletin package and must be added to your NGINX configuration.
server {
        # address and port accepted by the server
        listen   80; ## listen for ipv4
        #listen   [::]:80 default ipv6only=on; ## listen for ipv6

        # server IP to compare against http requests, uncomment and set proper value.
        # Enter the hostname or IP address you use to reach this server. If you run on your dev environment it might be localhost.
        # Note: If your vb install is in a folder inside your domain <mysite>/forum/install/path please change location directives defined below to include the path first. e.G:
        # vbulletin.com/forum
        #
        # css directive would be:
        # location = /forum/css\.php {
        #        rewrite ^ /forum/core/css.php break;
        #}
        #server_name      127.0.0.1;

        # document root for request,  uncomment and set proper value
    # this should reflect the path that your vBulletin is installed in. 
    # This is usually /var/www/public_html/forumpath
        #root   /var/www/public_html/forumpath;
