2) Rails App Software versions:

RUBY VERSION: 2.2.2 (2015-04-13 patchlevel 95) [x86_64-linux]

RUBYGEMS VERSION: 2.4.5

RAILS: 4.2.4 (Mentioned in ruby gem file)

1) Create the directory /etc/nginx/ssl:

mkdir /etc/nginx/ssl

2) Place the server.crt, server.key and exphosted.pem file in the above location

3) Run the following command

openssl dhparam -out /etc/nginx/ssl/dhp-2048.pem 2048

4) Edit /etc/nginx/sites-available/bigbluebutton and add the below changes:

server {
    listen         80;
    server_name  devmeeting01.exphosted.com;
    return 301 https://$server_name$request_uri;
}

server {
     listen 443 ssl;
     ssl_certificate /etc/nginx/ssl/server.crt;
     ssl_certificate_key /etc/nginx/ssl/server.key;
     ssl_session_cache shared:SSL:10m;
     ssl_session_timeout 10m;
     ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
     ssl_ciphers "ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS:!AES256";
     ssl_prefer_server_ciphers on;
     ssl_dhparam /etc/nginx/ssl/dhp-2048.pem;
     [...]
  
  # BigBlueButton landing page.
        location / {
           proxy_pass https://localhost:4444;
           proxy_redirect default;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           #root   /var/www/bigbluebutton-default;
           #index  index.html index.htm;
           #expires 1m;
        }

5) Edit the server.crt file and add the CA file(bundle.crt) content at the end.

6) Edit the file /etc/bigbluebutton/nginx/sip.nginx and change the protocol and port on the proxy_pass line as shown:

location /ws {
  proxy_pass https://159.203.102.65:7443;
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "Upgrade";
  proxy_read_timeout 6h;
  proxy_send_timeout 6h;
  client_body_timeout 6h;
  send_timeout 6h;
}

7) Edit the file /var/www/bigbluebutton/client/lib/bbb_webrtc_bridge_sip.js and change the line that selects the ‘ws’ protocol to use ‘wss’ instead:

var configuration = {
        uri: 'sip:' + encodeURIComponent(username) + '@' + server,
        wsServers: 'wss://' + server + '/ws',
        displayName: username,
        register: false,
        traceSip: true,
        autostart: false,
        userAgentString: "BigBlueButton",
        stunServers: stunsConfig['stunServers'],
        turnServers: stunsConfig['turnServers']
     };

8) Add this line in ~/bin/deploybbbclient.sh script

sed -e 's|http://|https://|g' -i src/conf/config.xml

9) Restart nginx

sudo /etc/init.d/nginx restart

10) Restart BBB

sudo bbb-conf --restart

11) Refer this link for more details:

http://docs.bigbluebutton.org/install/install.html#configuring-https-on-bigbluebutton

1) Set the following details in config/ssl_settings.yml file:

ca_file_path: "/etc/nginx/ssl/new-cert/bundle.crt"
key_file_path: "/etc/nginx/ssl/new-cert/server.key"
crt_file_path: "/etc/nginx/ssl/new-cert/server.crt"
use_ssl: true

2) If we are using webrick as the app server, add the following code in /deploy/expertus_meeting/current/bin/rails file

APP_PATH = File.expand_path('../../config/application', __FILE__)
require_relative '../config/boot'
require 'rails/commands/server'
require 'rack'
require 'webrick'
require 'webrick/https'

module Rails
  class Server < ::Rack::Server
    def default_options
      super.merge({
        :Port => 4444,
        :pid => File.expand_path("tmp/pids/server.pid"),
        :config => File.expand_path("config.ru"),
        :SSLEnable => true,
        :SSLVerifyClient => OpenSSL::SSL::VERIFY_NONE,
        :SSLPrivateKey => OpenSSL::PKey::RSA.new(File.open("/etc/nginx/ssl/new-cert/server.key").read),
        :SSLCertificate => OpenSSL::X509::Certificate.new(File.open("/etc/nginx/ssl/new-cert/server.crt").read),
        :SSLCertName => [["CN", WEBrick::Utils::getservername]],
      })
    end
  end
end
require 'rails/commands'
