StorageNode for the vStore Framework

A sample implementation of a storage node for the vStore framework. Please refer to the framework's main repository and Wiki for further documentation.

Installation on a Raspberry Pi

Install node.js:

  • curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
  • sudo apt-get install -y nodejs to install node.js 8.x and npm

(For older Raspberry Pi (e.g. <= Pi2A): https://raspberrypi.stackexchange.com/questions/48303/install-nodejs-for-all-raspberry-pi)

Install MongoDB

  • sudo apt-get install mongodb-server
  • MongoDB Config file: sudo nano /etc/mongodb.conf
  • sudo service mongodb start

Setup StorageNode server

Install tools needed for thumbnail creation:

  • sudo apt-get install libav-tools graphicsmagick

Clone the repository:

  • git clone https://github.com/Telecooperation/vstore-node
  • cd vstore-node

After cloning the repository, run npm install in the directory to install necessary modules.

Configure the port number and storage node type in the file app.js.

To run the node.js app in foreground:

  • node app.js

To run node.js in the background:

  • Install screen: sudo apt-get install screen
  • Start new screen: screen -dmS <screen name>
  • screen -S <screen name> -X stuff 'node app.js\n' (yes, stuff and \n are necessary!)

Attach to screen:

  • screen -r <screen name>

Kill screen:

  • screen -S <screen name> -X quit

Using the admin interface to MongoDB backend

To access the MongoDB database more easily and graphically, we use mongo-express. You can easily add, remove and view file information.

This can be called by visiting http://<address_of_node>:<port>/admin. The login credentials can be configured in the file mongo_express_config.js by changing the variables mongoexpressUser and mongoexpressPass.
