Deploy Architecture

To make the system deploy, the minimum deployment architecture is shown below, which consist of:

Hardware

Wearable Glass (Optional)
Teacher Client-Side — Personal Computer with Camera
Student Client-Side — Personal Computer with Camera
Server Side — 8 Core 16G Virtual Machine on ARM or x86 Platform

Software

Teacher Side: Windows 10 with a Web Browser that supports WebSockets.
Student Side: Windows 10 with a Web Browser that supports WebSockets.
Server Side: CentOS 7
Virtual Classroom
Tars
IEC

Installation on the PC side(Teacher/Student Client)

Install Windows 10
Install camera driver
Install Firefox browser

Create two Virtual Machines in the Cloud

For Tencent Cloud, refer to the following link to apply new instance:

Installation on Jenkins Slave

Install CentOS 7, refer to https://phoenixnap.com/kb/how-to-install-centos-7
Install IEC, refer to IEC Type1&2 Installation Guide for R2
Install Tars, refer to https://github.com/TarsCloud/Tars/blob/master/Install.md
Install Virtual Classroom

Note Well:

49.51.201.127 is the public IP Address of the Virtual Machine. The IP address should be modified to the IP address of the machine on which you want to deploy.

cd /root

yum install -y npm

yum install -y git

yum install -y docker

yum update -y

systemctl restart docker

sleep 3

npm install http-server -g

rm -rf openvidu-vr

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

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

sed -i 's/demos.openvidu.io/49.51.201.127/g' app.js

sleep 3

docker run --rm --name openvidu_server -d -p 4443:4443 -e openvidu.secret=MY_SECRET -e openvidu.publicurl=https://49.51.201.127:4443/ openvidu/openvidu-server-kms

sleep 6

Install Java for Jenkins Slave

For Slave Mode, install Java will be ok.

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

Installation on 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:

# systemctl status jenkins
* jenkins.service - LSB: Jenkins Automation Server
   Loaded: loaded (/etc/rc.d/init.d/jenkins; bad; vendor preset: disabled)
   Active: active (running) since Tue 2019-10-15 11:16:26 CST; 1min 15s ago
     Docs: man:systemd-sysv-generator(8)

Oct 15 11:16:26 VM_0_4_centos systemd[1]: Started LSB: Jenkins Automation Server.

Finally enable the Jenkins service to start on system boot.

sudo systemctl enable jenkins

output

# sudo systemctl enable jenkins
jenkins.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig jenkins on

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:

http://your_ip_or_domain:8080
