Reverse proxy


As XO-web and XO-server communicate with WebSockets, you need to have the mod_proxy, mod_proxy_http, mod_proxy_wstunnel and mod_rewrite modules enabled.

Please use this configuration in this order or it will not work. Do not forget the trailing slashes!:

RewriteEngine On
RewriteCond %{HTTP:upgrade} websocket [NC]
RewriteRule /[<path>]/(.*) ws://<xo-server ip>:<xo-server port>/$1 [L,P]

ProxyPass /[<path>]/ http://<xo-server ip>:<xo-server port>/
ProxyPassReverse /[<path>]/ http://<xo-server ip>:<xo-server port>/


Just configure your VirtualHost as usual (or your default site), with a location section like this one:

location /[<path>] {
  # Add some 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 $scheme;

  # Proxy configuration
  proxy_pass http://<XOA ip address>[:<port>]/;

  proxy_http_version 1.1;
  proxy_set_header Connection "upgrade";
  proxy_set_header Upgrade $http_upgrade;

  proxy_redirect default;

  # Issue
  proxy_read_timeout 1800; # Error will be only every 30m

  # For the VM import feature, this size must be larger than the file we want to upload.
  # Without a proper value, nginx will have error "client intended to send too large body"
  client_max_body_size 4G;

That's all!
