[sample nginx.conf file available?]

I see the nginx file in the _INSTALL folder, but it doesn't look like it's in the same format as my existing nginx.conf files. 

Do you have a sample file that I can use that looks like this? Is mine old? Is yours? 

Mine look like this:

server {
    server_name <my.url.com>;

    root   /usr/share/nginx/html/<my.url.com>;
    index index.php index.html index.htm;
    client_max_body_size 200M;

    location / {
        try_files $uri $uri/ /index.php?$args;
        #try_files $uri $uri/ =404;
    }

a quick adaptation of yours returns the following

nginx -t
nginx: [emerg] "location" directive is not allowed here in /etc/nginx/conf.d/some-conf-file.conf:42
nginx: configuration file /etc/nginx/nginx.conf test failed
