(Tami Graph installation)

  1. adduser knownodes
  2. su knownodes
  3. cd
  4. git clone https://github.com/CyberCRI/KnowNodes.git
  5. cd config
  6. copy all example config files to non example endings (DB.conf.js email.conf.js loggly.conf.js passport.conf.js settings.js testacular.conf.js)
  7. edit them: mongodb can be run locally (tested on ubuntu 12.04)
  8. download neo4j community edition 1.8.3, unpack in home directory, no systemd file yet, just run bin/neo4j start (port 7474 - edit DB.conf)
  9. install node packages: npm install

Deployment - making sure site is visible from the outside world (this differs and is very tami specific)

  1. add a new subdomain tamigraph.tami.org.il (at our domain name service web interface)
  2. edit haproxy on the router to add a redirect from that domain to the internal service (running on host/port)

Fedora specific

  1. setup systemd unit files: neo4j, knownodes


Ubuntu specific

  1. neo4j 1.8.2 is packaged (use: apt-cache showpkg neo4j), install via apt-get install neo4j=1.8.2 (1.8.3 not packaged, but 1.8.2 supposed to work fine)
    1. downgrading neo4j: delete data directory or service fails to start (/etc/init.d/neo4j start, see /var/log/neo4j/console.log): rm -R /var/lib/neo4j/data/graph.db

knownodes systemd unit file

knownodes requires packages: node-less (for lessc)

Issues

User creation - when it failed had to use a different email, no way to remove the existing failed attempt to create a user.
