Lisk

Lisk is a next generation crypto-currency and decentralized application platform, written entirely in JavaScript. For more information please refer to our website: https://lisk.io/.

NOTE: The following information is applicable to: Ubuntu 14.04, 16.04 (LTS) or 16.10 - x86_64.

Prerequisites - In order

• Tool chain components -- Used for compiling dependencies

  sudo apt-get install -y python build-essential curl automake autoconf libtool

• Git (https://github.com/git/git) -- Used for cloning and updating Lisk

  sudo apt-get install -y git

• Node.js (https://nodejs.org/) -- Node.js serves as the underlying engine for code execution.

  System wide via package manager:

  curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
  sudo apt-get install -y nodejs
  

  Locally using nvm:

  curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash
  nvm install v6.10.1
  

• Install PostgreSQL (version 9.6.2):

  curl -sL "https://downloads.lisk.io/scripts/setup_postgresql.Linux" | bash -
  sudo -u postgres createuser --createdb $USER
  createdb lisk_test
  createdb lisk_main
  sudo -u postgres psql -d lisk_test -c "alter user "$USER" with password 'password';"
  sudo -u postgres psql -d lisk_main -c "alter user "$USER" with password 'password';"
  

• Bower (http://bower.io/) -- Bower helps to install required JavaScript dependencies.

  npm install -g bower

• Grunt.js (http://gruntjs.com/) -- Grunt is used to compile the frontend code and serves other functions.

  npm install -g grunt-cli

• PM2 (https://github.com/Unitech/pm2) -- PM2 manages the node process for Lisk (Optional)

  npm install -g pm2

Installation Steps

Clone the Lisk repository using Git and initialize the modules.

git clone https://github.com/LiskHQ/lisk.git
cd lisk
npm install

Managing Lisk

To test that Lisk is built and configured correctly, run the following command:

node app.js

In a browser navigate to: http://localhost:8000 (for the mainnet) or http://localhost:7000 (for the testnet). If Lisk is running on a remote system, switch localhost for the external IP Address of the machine.

Once the process is verified as running correctly, CTRL+C and start the process with pm2. This will fork the process into the background and automatically recover the process if it fails.

pm2 start --name lisk app.js

After the process is started, its runtime status and log location can be retrieved by issuing the following command:

pm2 show lisk

To stop Lisk after it has been started with pm2, issue the following command:

pm2 stop lisk

NOTE: The port, address and config-path can be overridden by providing the relevant command switch:

pm2 start --name lisk app.js -- -p [port] -a [address] -c [config-path]

Tests

Before running any tests, please ensure Lisk is configured to run on the same testnet that is used by the test-suite.

Replace config.json and genesisBlock.json with the corresponding files under the test directory:

cp test/config.json test/genesisBlock.json .

NOTE: If the node was started with a different genesis block previous, trauncate the database before running tests.

dropdb lisk_test
createdb lisk_test

NOTE: The master passphrase for this genesis block is as follows:

wagon stock borrow episode laundry kitten salute link globe zero feed marble

Launch Lisk (runs on port 4000):

node app.js

Run the test suite:

npm test

Run individual tests:

npm test -- test/lib/accounts.js
npm test -- test/lib/transactions.js
