Here's a tutorial on how to reverse proxy Odoo using NGINX.

# Upstreams for the http and longpolling ports
# these (odoosrv and odoolong) vars will be used in other places in the conf file
# refer to:
#     http://nginx.org/en/docs/http/load_balancing.html

upstream odoosrv {
    server 127.0.0.1:8069 weight=1 fail_timeout=0;
}
upstream odoolong {
    server 127.0.0.1:8072 weight=1 fail_timeout=0;
}
server {
 listen 443 ssl;
 server_name www.example.com;
 access_log /var/log/nginx/access.log;
 error_log /var/log/nginx/error.log;
