Install Kurento media server

Kurento Media Server (KMS) has to be installed on Ubuntu 14.04 LTS (64 bits). In order to install the latest stable Kurento Media Server version (6.+) you have to type the following commands:

With trusty ubuntu version

echo "deb http://ubuntu.kurento.org trusty kms6" | sudo tee /etc/apt/sources.list.d/kurento.list
wget -O - http://ubuntu.kurento.org/kurento.gpg.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install kurento-media-server-6.0

With xenial ubuntu version

echo "deb http://ubuntu.kurento.org xenial kms6" | sudo tee /etc/apt/sources.list.d/kurento.list
wget -O - http://ubuntu.kurento.org/kurento.gpg.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install kurento-media-server-6.0

Disable ufw sudo ufw disable

Instance trigger Start sudo service kurento-media-server-6.0 start Stop sudo service kurento-media-server-6.0 stop

#Install Kurento module

sudo apt-get install kms-pointerdetector-6.0
sudo apt-get install kms-chroma-6.0
sudo apt-get install kms-crowddetector-6.0
sudo apt-get install kms-platedetector-6.0
sudo service kurento-media-server restart

Install node

sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install nodejs
sudo npm install -g n
sudo n lts
source ~/.bash_aliases
 
sudo npm install -g bower

Run Example

WITH PROJECT EXIST server.js FILE

git clone https://github.com/nhancv/ot-kurento-node-webrtc.git 
cd to /webrtc_server/kurento/<demo_dir>
npm install
node server.js

Issue when install server-app on vps with root account, sometimes bower not work => frontend js not working completely.

Solved: cd to static folder and install bowser dependencies manually cd /webrtc_server/kurento/<demo_dir>/static && bower --allow-root install

These instructions work only if Kurento Media Server is up and running in the same machine as the tutorial. However, it is possible to connect to a remote KMS in other machine, simply adding the argument ws_uri to the npm execution command, as follows: npm start -- --ws_uri=ws://kms_host:kms_port/kurento In this case you need to use npm version 2. To update it you can use this command: sudo npm install npm -g

Default kms_port: 8888

WITH PROJECT WITHOUT server.js FILE

sudo npm install -g http-server
bower install

Then, in each demo folder execute this command: http-server -p 8443 -S -C keys/server.crt -K keys/server.key

Finally, open https://localhost:8443/ in your browser to access to the demo.

Optional parameters https://example.com/index.html?ws_uri=wss://example.org/kurento

All demos accept following parameters: ws_uri: the WebSocket Kurento MediaServer endpoint. By default it connects to a Kurento MediaServer instance listening on the port 8433 on the same machine where it's being hosted the demo. The KMS must allow WSS (WebSocket Secure).

ice_servers: the TURN and STUN servers to use, formatted as a JSON string holding an array of RTCIceServerobjects (the same structure used when configuring a PeerConnection object), or an empty array to disabled them (this is faster and more reliable when doing tests on a local machine or LAN network). By default it use some random servers from a pre-defined list. https://example.com/index.html?ice_servers=[{"urls":"stun:stun1.example.net"},{"urls":"stun:stun2.example.net"}] https://example.com/index.html?ice_servers=[{"urls":"turn:turn.example.org","username":"user","credential":"myPassword"}] Other parameters specific to each demo can be found defined at the top of their index.js file. Securing Kurento Applications First, you need to change the configuration file of Kurento Media Server, i.e./etc/kurento/kurento.conf.json, uncommenting the following lines:

 "secure": {
	  "port": 8433,
	  "certificate": "defaultCertificate.pem",
	  "password": ""
	},

sudo apt-get install gnutls-bin

certtool --generate-privkey --outfile defaultCertificate.pem
echo 'organization = your organization name' > certtool.tmpl
certtool --generate-self-signed --load-privkey defaultCertificate.pem \
   --template certtool.tmpl >> defaultCertificate.pem

sudo cp defaultCertificate.pem /etc/kurento/
sudo chown kurento /etc/kurento/defaultCertificate.pem
sudo service kurento-media-server-6.0 restart

Go to https://localhost:8433 for self-sign Install https://chrome.google.com/webstore/detail/web-socket-client/lifhekgaodigcpmnakfhaaaboididbdn to check connection
