OpenMeeting is a conferencing software used for online training, web conferencing, presenting, document editing, collaborative whiteboard drawing, and user desktop sharing. It is built on HTML5, Flash and Red5 media server. OpenMeeting also provides mobile-client for Android and offers a private message center that allows users to chat, create polls, and cast votes.
In this tutorial, we will install and set up OpenMeeting on Alibaba Cloud Elastic Compute Service (ECS) along with Ubuntu 16.04.
Firstly, use the following command to update your Ubuntu system before proceeding with the installation of any type of package. For executing this command, remember to login from non-root user with Sudo privileges.
sudo apt update && sudo apt upgrade
Execute the following command to install software-properties-common.

MyBB supports MySQL and PostgreSQL. For this tutorial, we will use the MariaDB server for MySQL. By default, the Ubuntu repository has an older version of the MariaDB server. We need to add MariaDB repository to the Ubuntu system for using the new version of MariaDB by following the steps listed below.
Verify the keys by executing the command shown below.
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
Add the repository using the following command.
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://mirror.nodesdirect.com/mariadb/repo/10.2/ubuntu xenial main'
Now update the system by using the command below.
sudo apt update
Now install MariaDB using the following command.
sudo apt install -y mariadb-server
Start and enable the MariaDB server to ensure that after reboot, the server starts automatically.
sudo systemctl start mariadb
sudo systemctl enable mariadb
Now run the following command to enhance security of MariaDB server and set password for the root user.
sudo mysql_secure_installation
Also, connect to the MySQL shell as the root user by executing the command below and enter your password.
sudo mysql -u root -p
Execute the following MySQL queries in your MariaDB server.
CREATE DATABASE plane CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER 'aareez'@'localhost' IDENTIFIED BY '654321Ab';
GRANT ALL PRIVILEGES ON plane.* TO 'aareez'@'localhost';
FLUSH PRIVILEGES;
EXIT; Navigate to /var/webapps/openmeetings/WEB-INF/lib as shown below.
cd /var/webapps/openmeetings/WEB-INF/lib
Download Connecter J by executing the following command.
wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-8.0.13.zip
Now execute the command below to unzip the downloaded folder.
sudo unzip mysql-connector-java-8.0.13.zip
Now use the following command to move .jar file from /var/webapps/openmeetings/WEB-INF/lib/mysql-connector-java-8.0.13/ to /var/webapps/openmeetings/WEB-INF/lib/.
sudo mv -v /var/webapps/openmeetings/WEB-INF/lib/mysql-connector-java-8.0.13/mysql-connector-java-8.0.13.jar /var/webapps/openmeetings/WEB-INF/lib/
Let's take a look at the steps to install OpenMeeting.
Navigate to /var using the following command.
cd /var
Now, change ownership of /var directory as shown below.
sudo chown -R aareez:aareez /var
You will need the latest stable release of OpenMeeting to move ahead with the installation. Use the command below to get the latest release version.
wget http://www-eu.apache.org/dist/openmeetings/4.0.6/bin/apache-openmeetings-4.0.6.zip
Unzip the downloaded folder by using the following command.
unzip apache-openmeetings-4.0.6.zip
Now execute the following command to extract apache-openmeetings-4.0.6.zip.
rm -r apache-openmeetings-4.0.6.zip
To start the OpenMeeting application, you must execute the following command.
sudo su -s /bin/bash -c 'cd /var/ && sh red5.sh'
If you have activated firewalls, you need to define a rule in Alibaba Cloud security group for your cloud server to add an exception for port 80/TCP, 443/TCP, and 5080/TCP. You can enable these ports while creating ECS instance, but in case if you have forgotten to unblock these ports, you can follow the procedure in this guide: https://www.alibabacloud.com/help/doc-detail/25471.htm
Next, you need to configure OpenMeetings. Access OpenMeeting on web-browser via http://your_domain.tld/openmeetings:5080 to navigate to the following page.
Once, you click on the Next button, represented by ">" sign, you will be redirected to the database configuration page as shown below.
Click Check to see if database is connected successfully. Secondly, click the ">" button to proceed to the next step.
On the below screen, you can set up a username and password for the administrator account to access the admin panel.
So once you are on the following screen, complete the SMTP settings and click the " > " button to proceed towards the next step.

sudo systemctl enable nginx
On successful installation, you will see the following screen.
To install Node.js, execute the command below.
sudo apt-get install nodejs
It is imperative to set up a reverse proxy to access OpenMeeting. This will allow you to access OpenMeeting via domain name without using any port at the end of the address. You can implement the same by running the following command to create an Nginx configuration file using Nano editor.
sudo nano /etc/nginx/conf.d/open.conf
Now add the following text in the open file and save it.
server {
listen 80;
listen [::]:80;
server_name softpedia.xyz;
location / {
proxy_pass http://localhost:5080/;
}
}Now restart the Nginx server by executing the following command.
sudo systemctl restart nginx
