This chapter will describe the process of installing the system on a new server. The steps in this document will require that the user has knowledge of the chosen linux distribution and has some sense of NodeJS and MongoDB administration.

Track and Trace 2.0 can be installed on any Linux system able to run MongoDB, Nginx HTTP server and the NodeJS framework. This document will show the installation process on Ubuntu LTS 16.04 and the installation procedure will differ on different Linux distributions.

There is no obvious reason why TnT2.0 would not run on a Windows server, but this has not yet been tested and verified.

First, enable the repository for Mongo 3.6 to be used, since Ubuntu 16.04 uses an older repo by default:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list

Update and install MongoDB 3.6

sudo apt-get update
sudo apt-get install -y mongodb-org

Now you should be able to start the mongod daemon.

sudo service mongod start

And after that you should be able to verify the installation by connecting to the mongodb database.

mongo

IMPORTANT To ensure that the mongo database starts on system reboot make sure to enable the service:

  sudo systemctl enable mongod.service

Installation of the Nginx web server on Ubuntu 16.04 is straightforward:

sudo apt-get update
sudo apt-get install nginx
sudo ufw allow 'Nginx HTTP'
systemctl status nginx

To enable our webapp and TnT2 Client web pages edit the nginx configuration for the default site.

vi /etc/nginx/sites-enabled/default

Add the following under the location / tag:

location /app {
  alias /opt/node/TrackAndTrace2/apps/scanner;
}
location /client {
  alias /opt/node/TrackAndTrace2/client;
}

Change /opt/node/TrackAndTrace2 to whatever your install location is.

After this, simply reload the nginx service and we're done.

systemctl reload nginx

We need NodeJS and the npm package manager:

sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install nodejs

Now we create the installation directory and set the permissions to full access:

sudo mkdir /opt/node
cd /opt/node
sudo chmod a+rwx .
mkdir tnt2_[site]_[version]
ln -s tnt2_[site]_[version] TrackAndTrace2
cd TrackAndTrace2

Download and install the Track and Trace 2.0 system:

git clone -b [version] [gitrepo]

Install the required NPM-packages:

npm install

Substitute the configuration with the right one. If none exists, edit the configuration file.

cd config
rm tntconfig.js
ln -s tntconfig_[SITE].js tntconfig.js
cd ..

Install the PM2 process manager:

sudo npm install pm2 -g
pm2 startup

Follow the instructions.

Create the manifest archive directory:

mkdir manifestArchive

Add the proper configuration to the manifestsources collection of the MongoDB database pointed to by the configuration file.

mongo
use [database]
  db.manifestsources.insert( {
    "type" : "ftp",
    "host" : "[FTPHOST]",
    "port" : 21,
    "user" : "[FTPUSER]",
    "password" : "[FTPPASSWORD]",
    "description" : "[DESCRIPTION OF SOURCE]",
    "sendercode" : "[SENDERCODE ON MANIFEST]",
    "path" : "[PATH ON REMOTE SERVER]",
    "archiveto" : "[PATH TO ARCHIVE TO ON THE REMOTE SERVER]",
    "localarchiveto" : "/opt/node/TrackAndTrace2/manifestsArchive",
    "active" : true,
    "filter" : [
      [ADD REGULAR EXPRESSIONS TO MATCH MANIFEST HERE]
    ]
  } );
  exit;

Start the services for the TnT2 system:

cd /opt/node/TrackAndTrace2
npm run manifestimporter
npm run manifestpoimporter
npm run manifestvalidator
npm run manifestbuilder
npm run mappingimporter
npm run storeroomimporter
npm run userimporter
npm run restservice
npm run worker
npm run integration
pm2 save

Verify that all services are running:

pm2 list

Check that there are no errors in the logs:

pm2 logs

Add the needed indexes to the database collections:

mongo
use [DATABASE]
  db.manifests.createIndex( {"parser.parsed":-1});
  db.transactions.createIndex( {"timestamp":-1});
  db.MQdata.createIndex( {q:1} );
  db.items.createIndex( {parent_id:1} );
  db.packs.createIndex( {parent_id:1} );
  db.transactions.createIndex( {timestamp:1} );
exit

There, the system is now installed and running. Make sure to log in to the client and set the active-flag on the active stores prior to importing manifests, otherwise the manifest import process will fail as there are no active stores.
