README

KAI knowledge management system. A search engine/document management system written in Java, using Apache Cassandra (3.9) and Hazelcast and the spaCy parser. Uses GRADLE for build. Missing some data-files I still need to upload due to their size.

How do I get set up on DEV?

• building the system
• see below for installing node and others
• cassandra authorization setup
• swagger use / see if services are up

How do I get set up on a server?

• build the system

gradle clean build createJarDependencies -x test

cd web/admin
grunt build

cd web/search
grunt build

ansible-playbook ansible/setup-cluster-one.yml --extra-vars "web_port=8085 server_port=10080 rf=1 external_name=peter-vm" 

installing nodejs, grunt, bower, yeoman, ruby and compass on MINT and Ubuntu

sudo apt-get install -y nodejs
sudo apt-get install -y npm
sudo apt-get install -y ruby-full
sudo gem install compass
sudo npm install -g n
sudo n stable
sudo npm install -g yo bower grunt-cli
sudo npm install -g gruntjs/grunt-contrib-imagemin jasmine-core grunt-karma karma karma-phantomjs-launcher phantomjs-prebuilt
cd web/admin
npm install
bower install

errors with NodeJS version > 5

Use NodeJS version 5, not 6 or later

node --version

to rollback to version 5:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.1/install.sh | bash
exit

nvm ls
nvm install 5
nvm use 5
node --version

errors with imagemin

cd node_modules/grunt-contrib-imagemin
npm install imagemin@4.0.0
sudo chown -R peter. /home/peter/.config

Grunt commands for server

cd resources/web-app

to serve and debug, will open browser

grunt serve

to build an optimized source

grunt build

cassandra auth setup (not required for dev)

edit cassandra.yaml and change the authenticator

authenticator: AllowAllAuthenticator

authenticator: PasswordAuthenticator

cqlsh -u cassandra -p cassandra

set new super user

CREATE USER viki with PASSWORD 'password' SUPERUSER;

logout, log back in as new user and remove cassandra default

DROP USER cassandra;

using swagger

• to get the swagger.json from the api, use the url [http://localhost:8085/api-doc/swagger.json]
• to use the full web interface [http://localhost:8085/swagger/]

Ansible

Ansible is a powerful tool for deploying and managing servers in clusters. Ansible will ensure that your machines are up-to-date as well as have all the required software and changes. See: http://docs.ansible.com/

Each of the target machines is expected to be a Centos 7 machine (any version). Ansible will install all other necessary software needed for running this service, including the auto OS updater (yum-cron).

• installing Ansible on Ubuntu

sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install ansible

• setup Ansible on Ubuntu put into:

/etc/ansible/hosts

and

~/ansible_hosts

the values

[kai-single-node]
ip-address-or-hostname-1
ip-address-or-hostname-2

and many more if you need them

• setup the ssh certificates; run as root:

ssh-keygen -t rsa -b 4096

on each of these machines if not already done, then setup yourself on these hosts in /root/.ssh/authorized_keys
to do this use: 

ssh-copy-id root@ip-address-or-hostname-1, etc.

• then test these servers using

ansible all -m ping -u root

• before running this script, FIRST BUILD the project

mvn clean install deploy

• run this playbook using

ansible-playbook ansible/setup.yml

• once the playbook has finished successfully you can test the server by browsing to

http://ip-address-or-hostname-1:8085/api/swagger/
