Lisk Explorer installation for Linux

Prerequisites

These programs and resources are required to install and run Lisk Explorer.

  • Node.js v8.11.2 or higher (https://nodejs.org/) -- Node.js serves as the underlying engine for code execution.

       curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
   sudo apt-get install -y nodejs

  • Update npm to the version 6.x

       npm install -g npm@6

  • Redis (http://redis.io) -- Redis is used for caching parsed exchange data.

       sudo apt-get install -y redis-server

    Note: you can change your port at this step if you want to have more Redis instances in the future. Remember to adjust the environment variable REDIS_PORT accordingly.

  • Freegeoip (https://github.com/fiorix/freegeoip) -- Freegeoip is used by the Network Monitor for IP address geo-location.

       wget https://github.com/fiorix/freegeoip/releases/download/v3.4.1/freegeoip-3.4.1-linux-amd64.tar.gz
   tar -zxf freegeoip-3.4.1-linux-amd64.tar.gz
   ln -s freegeoip-3.4.1-linux-amd64 freegeoip
   nohup ./freegeoip/freegeoip > ./freegeoip/freegeoip.log 2>&1 &

  • PM2 (https://github.com/Unitech/pm2) -- PM2 manages the node process for Lisk Explorer and handles log rotation (Highly Recommended)

     npm install -g pm2

  • Bower (https://bower.io/) -- Bower is used to look after frontend libraries.

     sudo npm install -g bower
