Install signaling server

1. Install KMS

Ubuntu Xenial 16.04

sudo echo "deb [arch=amd64] http://ubuntu.openvidu.io/6.11.0 xenial kms6" | sudo tee /etc/apt/sources.list.d/kurento.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5AFA7A83
sudo apt-get update
sudo apt-get -y install kurento-media-server

Ubuntu Bionic 18.04

sudo echo "deb [arch=amd64] http://ubuntu.openvidu.io/6.11.0 bionic kms6" | sudo tee /etc/apt/sources.list.d/kurento.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5AFA7A83
sudo apt-get update
sudo apt-get -y install kurento-media-server

After installing KMS, it is necessary to change the default user running it to the current one with this line:

sudo sed -i "s/DAEMON_USER=\"kurento\"/DAEMON_USER=\"${USER}\"/g" /etc/default/kurento-media-server

2. Install COTURN

sudo apt-get -y install coturn

This is a great implementation of a STUN/TURN server, necessary for connecting your users under some complicated circumstances. You can check its documentation here.

3. Install Redis

sudo apt-get -y install redis-server

4. File console /etc/kurento/modules/kurento/WebRtcEndpoint.conf.ini

stunServerAddress=YOUR_MACHINE_PUBLIC_IP
stunServerPort=3478

5. File console /etc/turnserver.conf

external-ip=YOUR_MACHINE_PUBLIC_IP
listening-port=3478
fingerprint
lt-cred-mech
max-port=65535
min-port=40000
pidfile="/var/run/turnserver.pid"
realm=openvidu
simple-log
redis-userdb="ip=127.0.0.1 dbname=0 password=turn connect_timeout=30"
verbose

6. File /etc/default/coturn

TURNSERVER_ENABLED=1

7. Init services

sudo service redis-server restart
sudo service coturn restart
sudo service kurento-media-server restart

8. Init Openvidu Server JAR executable

java -jar -Dopenvidu.secret=YOUR_SECRET -Dopenvidu.publicurl=https://YOUR_MACHINE_PUBLIC_IP:4443/ openvidu-server-{VERSION}.jar

Being YOUR_SECRET the password you want for securing your OpenVidu Server. This will be needed for connecting to OpenVidu Server dashboard and for consuming OpenVidu Server REST API. Keep it safe!
