Proxy Pass odoo 8069 to 80 with enhancements

 

There are couple of things that you should be familiar before going through the steps

1. Odoo
2. Linux
3. Nginx

So i assume the application was now accessible through your port 8069, eg. 188.xx.xx.xx:8069 or yourdomain.com:8069 and your requirement would be

1. your application should be run on port 80, or your domain eg: yourdomain.com
2. your application should be run under secure connection
3. your application should not be accessible through port 8069 anymore     

sudo apt-get install nginx
nano /etc/nginx/sites-available/odoo

upstream odoo {
    server 127.0.0.1:8069;
}

server {
    listen 80;
    server_name yourdomain.com;
    root        /usr/share/nginx/html;
    index       index.html index.htm;
    access_log  /var/log/nginx/yourdomaincom.access.log;
    error_log   /var/log/nginx/yourdomaincom.error.log;

    location / {
        proxy_pass  http://odoo;
        # force timeouts if the backend dies
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
        proxy_redirect off;

        # set headers
        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 https;
    }

    # cache some static data in memory for 60mins
    location ~* /web/static/ {
        proxy_cache_valid 200 60m;
        proxy_buffering on;
        expires 864000;
        proxy_pass http://odoo;
    }
}
Save and exit
