I was wondering if I could get some advice on my nginx configuration. The config seems to be working, but I'm unsure if I'm doing everything properly. The basic idea is to have a Jira and Confluence server (in separate Tomcat instances) running on the same machine, with nginx in front to handle SSL for both. I want only SSL connections to be made to Jira/Confluence. Jira is running on 127.0.0.1:9090 and Confluence on 127.0.0.1:8080. Here is my nginx.conf, any advice or tips would be greatly appreciated.

user              nginx;
worker_processes  1;

error_log         /var/log/nginx/error.log;
pid               /var/run/nginx.pid;

events {
    worker_connections  1024;
}

                      '"$status" $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
