Allow BBB to run behind a proxy the avoid gUM permission queries per node The idea is to run a loadbalancer node which maps each BBB node to a path. That way each user gets only one gUM permission query for a cluster. The loadbalancer node only serves the html5 client, each BBB node will serve its own API and handle the websockets for freeswitch and bbb-webrtc-sfu. Configuring a cluster setup =========================== * let bbb-lb.example.com be the loadbalancer node * let bbb-01.eaxmple.com be a BBB node Loadbalancer ------------ On the loadbalancer node add an nginx configuration similar to this one for each BBB node: ``` location /bbb-01/html5client/ { proxy_pass https://bbb-01.example.com/bbb-01/html5client/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "Upgrade"; } ``` BBB Node -------- On the BBB node add the following options to `/etc/bigbluebutton/bbb-web.properties`: ``` defaultHTML5ClientUrl=https://bbb-lb.example.com/bbb-01/html5client/join presentationBaseURL=https://bbb-01.example.com/bigbluebutton/presentation accessControlAllowOrigin=https://bbb-lb.example.com ``` Add the following options to `/etc/bigbluebutton/bbb-html5.yml`: ``` public: app: basename: '/bbb-01/html5client' bbbWebBase: 'https://bbb-01.eaxmple.com/bigbluebutton' learningDashboardBase: 'https://bbb-01.eaxmple.com/learning-dashboard' media: stunTurnServersFetchAddress: 'https://bbb-01.eaxmple.com/bigbluebutton/api/stuns' sip_ws_host: 'bbb-01.eaxmple.com' presentation: uploadEndpoint: 'https://bbb-01.eaxmple.com/bigbluebutton/presentation/upload' ``` Create the following unit file overrides: * `/etc/systemd/system/bbb-html5-frontend@.service.d/cluster.conf` * `/etc/systemd/system/bbb-html5-backend@.service.d/cluster.conf` with the following content: ``` [Service] Environment=ROOT_URL=https://127.0.0.1/bbb-01/html5client ``` Change the nginx `$bbb_loadbalancer_node` variable to the name of the load balancer node in `/etc/bigbluebutton/nginx/loadbalancer.nginx` to allow CORS requests: ``` set $bbb_loadbalancer_node https://bbb-lb.example.com ``` Prepend the mount point of bbb-html5 in all location sections except from the `location @html5client` section in `/etc/bigbluebutton/nginx/bbb-html5.nginx` ``` location @html5client { ... } location /bbb-01/html5client/locales { ... } ``` 2021-11-19 05:52:20 +08:00			`const getCurrentPresentation = (podId) => Presentations.findOne({`
