BigBlueButton: Changing of port number from 80 to new one

By default,

* Nginx server holds the port 80

* BigBlueButton listens the port no 80 for the application called bigbluebutton which is hosted on Nginx server.

In some situations,

• Apache may needs port 80 to run
•  Or some other service wants that ports to run

In that time, the listening port of BBB needs to be changed to some other no (for ex. 9099). This can be done by following steps.

1. To reconfigure the port no listened by BBB to 9090
   
   $ bbb-conf --setip <your current ip or domain name>:9090
   
   To know the exact IP or domain name used by the server, use
   
   $ bbb-conf --check
   
   This will gives all the current running configuration of BBB.
2. Till, only the listening port no of BBB is changed. To change the port no of Nginx server, edit the server configuration file at '/etc/nginx/sites-available/default' and change the port no to 9090. Then, restart the server by
   
   $ /etc/init.d/nginx restart
3. Here after the BBB application can be accessed by the following url
   
   http://<localhost or domain name>:9090
