Installation on VM2(Jenkins Master)

Jenkins is a Java application, so the first step is to install Java. Run the following command to install the OpenJDK 8 package:

sudo yum install -y java-1.8.0-openjdk-devel

The next step is to enable the Jenkins repository. To do that, import the GPG key using the following curl command:

curl --silent --location http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo | sudo tee /etc/yum.repos.d/jenkins.repo

And add the repository to your system with:

sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key

Once the repository is enabled, install the latest stable version of Jenkins by typing:

sudo yum install -y jenkins

After the installation process is completed, start the Jenkins service with:

sudo systemctl start jenkins

To check whether it started successfully run:

systemctl status jenkins

You should see something similar to this:

Adjust the Firewall If you are installing Jenkins on a remote CentOS server that is protected by a firewall you need to port 8080.

Use the following commands to open the necessary port:

sudo firewall-cmd --permanent --zone=public --add-port=8080/tcp
sudo firewall-cmd --reload

Setting Up Jenkins To set up your new Jenkins installation, open your browser and type your domain or IP address followed by port 8080:

Developer Guide and Troubleshooting

Virtual Classroom demo includes two parts: (1) server side and (2) client side. The technologies used to develop these applications includes WebGL, Three.js and JavaScript.

The code could be find at:

git clone https://github.com/OpenVidu/openvidu-vr.git

cd /root/openvidu-vr/openvidu-vr-room/

sed -i 's/demos.openvidu.io/${Local_IP_Address}/g' app.js

To execute:

docker run --rm --name openvidu_server -d -p 4443:4443 -e openvidu.secret=MY_SECRET -e openvidu.publicurl=https://${Local_IP_Address}:4443/ openvidu/openvidu-server-kms
