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/.

Prerequisites - In order

This sections provides details on what you need install on your system in order to run Lisk.

System Install

• Tool chain components -- Used for compiling dependencies

  • Ubuntu/Debian:

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

  • MacOS 10.12-10.13 (Sierra/High Sierra):

    Make sure that you have both XCode and Homebrew installed on your machine.

    Update homebrew and install dependencies:

    brew update
    brew doctor
    brew install curl automake autoconf libtool
    

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

  • Ubuntu/Debian:

    sudo apt-get install -y git
    

  • MacOS 10.12-10.13 (Sierra/High Sierra):

    brew install git
    

Node.js (https://nodejs.org/)

• Node.js serves as the underlying engine for code execution.

  Install System wide via package manager:

  • Ubuntu/Debian:

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

  • MacOS 10.12-10.13 (Sierra/High Sierra):

    brew install [email protected]
    

• (Recommended) Install using a version manager such as nvm.

  1. Install nvm following their instructions (https://github.com/creationix/nvm#installation)
  2. Install the correct version of Node.js using nvm:

  nvm install 6.12.3
  

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

  npm install -g pm2
  

PostgreSQL (version 9.6):

• Ubuntu/Debian:

  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';"
  

• MacOS 10.12-10.13 (Sierra/High Sierra):

  brew install [email protected]
  initdb /usr/local/var/postgres -E utf8
  brew services start [email protected]
  createdb lisk_test
  createdb lisk_main
  

Installing Redis

• Ubuntu/Debian:

  sudo apt-get install redis-server
  

  Start redis:

  service redis start
  

  Stop redis:

  service redis stop
  

• MacOS 10.12-10.13 (Sierra/High Sierra):

  brew install redis
  

  Start redis:

  brew services start redis
  

  Stop redis:

  brew services stop redis
  

NOTE: Lisk does not run on the redis default port of 6379. Instead it is configured to run on port: 6380. Because of this, in order for Lisk to run, you have one of two options:

1. Change the Lisk configuration

Update the redis port configuration in both config.json and test/data/config.json. Note that this is the easiest option, however, be mindful of reverting the changes should you make a pull request.

2. Change the Redis launch configuration

Update the launch configuration file on your system. Note that their a number of ways to do this. The following is one way:

1. Stop redis-server
2. Edit the file redis.conf and change: port 6379 to port 6380
   • Ubuntu/Debian: /etc/redis/redis.conf
   • MacOS: /usr/local/etc/redis.conf
3. Start redis-server

Now confirm that redis is running on port 6380:

redis-cli -p 6380
ping

And you should get the result PONG.

Installation Steps

Clone the Lisk repository using git and initialize the modules.

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

Managing Lisk

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

node app.js

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

Preparing Node

1. Recreate the database in order to run the tests against a new blockchain:

dropdb lisk_test
createdb lisk_test

2. Ensure Lisk is configured to run on the same local network used by the tests. Replace the files config.json and genesis_block.json with those located under the test/data directory:

cp test/data/config.json test/data/genesis_block.json .

3. Launch Lisk (runs on port 4000):

NODE_ENV=test node app.js

Running Tests

Tests are run using the following command:

npm test -- mocha:<tag>:<suite>:[section]

• Where tag can be one of slow | unstable | untagged | extensive (required)
• Where suite can be one of unit | functional | integration (required)
• Where section depending of the chosen suite can be:
  • when functional --> get | post | ws | system (optional)

Individual test files can be run using the following command:

npm run mocha -- path/to/test.js

Genesis Account

The master passphrase for the genesis block used by the tests is as follows:

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