Deploy BigBlueButton on your Bare Metal Cloud Server
BigBlueButton is a powerful web conference system, allowing to communicate with remote team members over fully encrypted connections using TLS/SSL. After having successfully deployed the application for everyone during the COVID period, we will show you how to deploy a BigBlueButton platform on your servers. The application was developed for academic use and supports a large number of concurent users in each conference room.
The application can be deployed on Scaleway Bare Metal Servers and allows you to have access to features such as:
- Sharing of screens, presentations, external videos …
- A collaborative whiteboard
- Invitation to a conference through a simple custom URL
- Built-in chat for exchanging messages during video conferencing
- Survey integrated into the videoconferencing system
- Conference recording
As a reminder, Scaleway has been making the BigBlueButton and Jitsi platforms available to everyone free of charge on its Cloud infrastructures since the beginning of the COVID-Project “Ensemble”:
BigBlueButton is open-source software and can be used on Bare Metal Servers without any additional license cost.
This tutorial is composed of several steps. The first section shows you have to deploy BigBlueButton on a Scaleway Bare Metal Server. The second, advanced, section is intended for users who want to take their configurations further.
Log yourself into to your Scaleway console. The dashboard displays once logged in.
Click Bare Metal in the Compute section of the side menu:
Click Create a Bare Metal Server to order a new server:
Once the server is delivered, click the Install button on the Bare Metal start page to install the operating system on the server.
Choose the Version BigBlueButton 16.04 image during the installation of the server, add the SSH keys you want to autorize to connect to the machine and click the Install button to launch the installation.
Add the SSH keys for which you would like to authorize the connection to the machine, and click the Install button to start the installation. To learn more about how to generate the keys, see the documentation: How to configure SSH keys
The installation of the server launches and will run for about 30 minutes. Once it finishes you will see the URL to connect to your BigBlueButton interface in the description of the machine:
Point your web browser to the URL shown in your Scaleway console. The BigBlueButton Greenlight frontend displays:
Continue with the creation of an admin user to manage your BigBlueButton server.
By default everyone can create a user account on the BigBlueButton server. However, it is possible to restrict the creation of user accounts from the admin panel.
Open your web browser and go to the domain name of your BigBlueButton server, for example
The Greenlight front-end displays. Click Sign up to create a new user.
Fill in the required parameters for the new user:
- Full name: The users full name
- Email: The users email address
- Password: A secret password for the user
- Password Confirmation: Confirmation of the users password
Once all values are set, click Sign up to create the new user account.
The users home page displays:
A Home Room is created by default for the new user. You can share the public link of the room for others to join it. Once you are ready, start the conference by clicking on Start. You will join the conference room with moderator privileges.
If required you can create addional rooms by clicking Create a Room. Each of the rooms may have its own configuration and a unique URL to share.
Once connected to the conference, you will be asked if you want to enable your computer microphone to be able to speak or to listen to the conference only. This choice is not definitive and can be changed at anytime during the conference.
Note: Upon the first connection you may be asked to allow access to your camera and microphone for the service. This is required to be able to communicate using BigBlueButton. Scaleway does not store your video or audio information and they are shared only within your conference room.
The BigBlueButton main communication screen displays:
The main options are:
- Mute: Mute or unmute the microphone of your device
- Leave Audio: Leave the audio stream of the conference while remaining connected to
the conference room. You can follow the presentation or interact with other users
in the chat. To join the audio stream again click the icon.
- Camera: Disable or enable sharing of the webcam of your local device. The camera is disabled
by default. Click the icon to enable it.
- Presenter tools: If you are a moderator or have been granted presenter privileges during
a conference, you can use this button to launch polls, upload presentations, or
share external videos in the conference.
In case the video or audio quality is not optimal or the application uses too many resources (CPU/RAM) on your local machine, you can disable webcam sharing:
Click the Options button in the right corner of the screen, then on Settings in the menu.
Disable webcams in the Data Savings tab. Optionally desktop sharing can be disabled too for further bandwidth savings.
Click OK to validate:
If you have joined a conference as a moderator, you have advanced privileges. Moderators can perform the following actions on guests:
Note: As a moderator, your name icon is squared. On the contrary, if you are a guest, your name icon is circled.
- Mute user: Moderators can mute guests to restrict them from speaking during the conference. The user can unmute himself if a global mute has been removed from the conference
- Make presenter: Give permission to a guest to be the presenter. Presenters have the possibilities to launch polls, upload presentations, or share external videos in the conference.
- Promote to moderator: Promote a guest to a moderator. The user will have the same privileges as the initial moderator.
- Remove user: Remove guests from the conference.
The moderator options are available by clicking on a regular user from the users list:
In addition, you have several other privileges available for the entire conference room. Click the star wheel next to Users to display the options available to the moderator.
- Clear all status icon
- Mute all users
- Mute all users except the presenter
- Save user names
- Lock viewers
- Create breakout rooms
- Write closed captions
A presenter can be any user in the conference, limited to only one presenter at a time in each conference room. Any moderator can make any user a presenter, including themselves.
A presenter has access to the following features:
- Upload presentation slides
- Use the whiteboard draw sketches
- Enable/disable the multi-user whiteboard
- Start a poll
- Share a video
- Share their screen
The presenter features are available by clicking on the Presenter Tools button:
In this section, you will learn how to:
- Configure the administrator account to configure advanced settings in the Greenlight web interface.
- Install BigBlueButton manually on a dedicated server runnning on Ubuntu 16.04 LTS
Note: These steps are optional and require some basic Linux knowledge to be executed.
To manage advanced settings on your BigBlueButton server, you need to create an Administraor Account for Greenlight. The administrator account allows you to manage users, customize the Greenlight interface and to enable or disable features such as the recording of conferences.
To create the administrator account, connect yourself to your Bare Metal server using SSH:
Run the following command from the command line to create a default admin user:
docker exec greenlight-v2 bundle exec rake admin:create
The following output displays once the account has been created:
Account succesfully created.
PLEASE CHANGE YOUR PASSWORD IMMEDIATELYImportant:
