Create an Nginx config file that records the logs and proxy passes the input requests on localhost:80 to localhost:880.
Here's a simple Nginx configuration file that proxy passes requests from localhost:80 to localhost:880 and records logs:

	http {
		log_format custom_log_format '$remote_addr - $remote_user [$time_local] '
									 '$request $status $body_bytes_sent '
									 '$http_referer $http_user_agent';
									 
		access_log /var/log/nginx/access.log custom_log_format;
		error_log /var/log/nginx/error.log;

		server {
			listen 80;

			location / {
				proxy_pass http://localhost:880;
				proxy_set_header Host $host;
				proxy_set_header X-Real-IP $remote_addr;
				proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			}
		}
	}
	
	events {
		worker_connections 1024;
	}

This configuration assumes that you have the appropriate permissions to write logs to `/var/log/nginx/`. Be sure to adjust the log paths and log format as needed for your specific environment.

Save the configuration file (e.g., `my_nginx.conf`) and start Nginx with the custom configuration:

	sudo nginx -c /path/to/my_nginx.conf
What are the appropriate permissions? How can I check these permissions and fix them if necessary?
