ILIAS-7-Install-Tutorial for Ubuntu 20.04

Node install

Install Node

The ILIAS-Chatsystem was completely new implemented in 5.2. So lets have a look how to get it work. It runs with node. The problem is: How to install node? There are a lot of pitfalls:

  1. If you installed it via apt-get install node node-legacy npm you run in the following problem:
    1. The version auf node 4.2.x is to low for the actual mathjax version and for etherpad-lite
    2. Hint for Plesk users: Please create a backup image bevor proceed (believe me, it`s important)

The first step is to check if node or npm are already installed.

  • node --version
  • nodejs --version
  • npm --version

To install it run:

  • cd /root
  • curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
    • Please do not go higher than node version 14 because of the chat does not support it
  • apt-get install -y nodejs yarn
  • export NODE_ENV=production
After the installation, check the versions:
  • Check Node: node --version
  • Check NPM: npm --version
  • Check the nodeapath and keep the result in mind: whereis node - this could give the green nodepath: node: /home/ilias/local/bin/node or /usr/local/bin/node
