Home control server unit that works together with IoT-raspberry
It is strongly recommended to use SSL! If you want to disable SSL, set useSSL to false in your config.js.
Place your SSL files in /etc/letsencrypt on your host machine.
MongoDB data is stored in /var/lib/mongodb-iot-server.
Build the docker containers with
docker-compose build
docker-compose run --rm node ./install
Start the Iot-Server
docker-compose up -d
To stop
docker-compose down
To open a bash of a running IoT-Server container
docker-compose exec node bash
To open a bash of a stopped IoT-Server container
docker-compose run --rm node bash
apt-get update
apt-get install -y git build-essential
Install node 6 or above, as described here: https://nodejs.org/en/download/package-manager/
curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
apt-get install -y nodejs
As described here: https://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
Use either
apt-get install mongodb
or someting like
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-3.2.list
apt-get update
apt-get install -y mongodb-org
service mongod start
SSL is strictly necessary for operating the IoT-server. All the IoT-raspberrys talk to your server over an encrypted SSL tunnel.
Install letsencrypt
cd /opt
git clone https://github.com/letsencrypt/letsencrypt
Create certs for your domain
/opt/letsencrypt/letsencrypt-auto certonly --agree-tos --cert-path /opt/keys --standalone --renew-by-default --email mueller.dav@gmail.com -d d1303.de
Create a symlink in /opt/keys now or change the config.js to match the generated certificates.
ln -s /etc/letsencrypt/live/d1303.de /opt/keys
Can be automated by a cronjob. As the certificates are valid for 90 days currently, once per month should be good enough.
self signed?
If you want to or have to create your own ssl certificate and can't use letsencrypt, do the following:
mkdir /opt/keys && cd /opt/keys
openssl genrsa -out privkey.pem 2048
openssl req -new -key privkey.pem -out csr.pem -subj "/C=DE/ST=Hessen/L=Darmstadt/O=Dis/CN=www.foobar.com"
openssl req -x509 -days 365 -key privkey.pem -in csr.pem -out cert.pem
Change the config accordingly to:
sslPrivateKeyPath: '/opt/keys/privkey.pem',
sslCertificate: '/opt/keys/cert.pem',
sslCa: false
npm install -g bower gulp node-gyp
git clone https://github.com/d89/IoT-server.git /var/www/IoT-server
cd /var/www/IoT-server
mkdir logs uploads
npm install
bower install --allow-root
gulp
chmod +x update
cd /var/www/IoT-server/server
cp config.js.sample config.js
nano config.js
Important parts of the configuration
SSL is necessary (see section above).
- port: The port the webserver runs on.
- sslPrivateKeyPath: Path to your private key pem file.
- sslCertificate: path to your certificate file.
- sslCa: your certificate chain.
- gcmApiKey: the api key of your google cloud messenging api if you want to utilize push messages (more to be described soon).
- mediaBasePath: Path where videos are stored, that the raspberry uploads (only relevant, if you have a camera on your raspberry).
- dsn: config base DSN for your mongodb database
for a quick launch, while you are connected via SSH:
cd /var/www/IoT-server/server
node index.js
For a more sophisticated operation, use a launch script.
npm install -g pm2
cd /var/www/IoT-server/server && pm2 start index.js --name iot-server && pm2 startup
restart service
pm2 restart iot-server
pm2 stop iot-server
logs and monitoring
pm2 logs iot-server
pm2 show iot-server
pm2 list iot-server
pm2 monit iot-server
Without data point aggregation, your mongodb database will fairly quick overflow. Once an hour, the datapoints are aggregated to an hourly level. Datapoints older than one week are aggregated to a "per day" level.
Add this to your /etc/crontab
0 * * * * root cd /var/www/IoT-server/server && node aggregator.js >/dev/null
37 13 * * * root cd /var/www/IoT-server/server && node sendpush.js >/dev/null
The second script executes once a day (at which time doesn't matter, so I put 13:37). It sends a daily summary via GCM push to all registered browsers that once connected to a raspberry.
