Hi Admin

Yes, your scenario is feasible! You can use Nginx on server 1 (10.0.0.1) as a reverse proxy to handle traffic for multiple Odoo instances running on different backend servers (server 2, server 3, and server 4). Below, I’ll provide a step-by-step configuration guide and example Nginx configuration.

What is your nginx conf?

i would presume this sample as example: 

# /etc/nginx/conf.d/odoo_reverse_proxy.conf

# Upstream servers for Odoo
upstream odoo_server_2 {
    server 10.0.0.2:8069;
}

upstream odoo_server_3 {
    server 10.0.0.3:8069;
}

upstream odoo_server_4 {
    server 10.0.0.4:8069;
}

# Reverse proxy for Odoo instance on server 2
server {
    listen 80;
    server_name odoo-server2.example.com;

    location / {
        proxy_pass http://odoo_server_2;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

# Reverse proxy for Odoo instance on server 3
server {
    listen 80;
    server_name odoo-server3.example.com;

    location / {
        proxy_pass http://odoo_server_3;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

# Reverse proxy for Odoo instance on server 4
server {
    listen 80;
    server_name odoo-server4.example.com;

    location / {
        proxy_pass http://odoo_server_4;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Hope it helps you

well,

• I used dns name and not ip address... but ok
• not use 443 protocol? i want acces to https://<nginx server>...
• i used Proxy_set_header X-Forwarded-Host.. no good?

and on odoo server, i must configure nginx reverse proxy (how in a standard install)?
