EMR and HIS system for transgender health nucleus

Installation

This process assumes that you are using Ubuntu 16.04 on server machine. The server of the system is executed on Node.js. We started with its installation.

$ cd ~
$ curl -sL https://deb.nodesource.com/setup_6.x -o nodesource_setup.sh
$ sudo bash nodesource_setup.sh
$ sudo apt-get install nodejs
$ sudo apt-get install build-essential

Update NPM to use recent packages made available and used in the project.

$ npm config get prefix
$ mkdir ~/.npm-global
$ npm config set prefix '~/.npm-global'
$ sudo nano ~/.profile

Add this line.

export PATH=~/.npm-global/bin:$PATH

Back on the terminal (Ctrl + o and Ctrl + x).

$ source ~/.profile
$ npm install npm@latest -g

In some cases NPM may not update globally, due to a pointer failure between directories. You can try this to solve.

$ curl -L https://www.npmjs.com/install.sh | sudo sh

The system uses MongoDB as the database, let's install it as a service.

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6
$ echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list
$ sudo apt-get update
$ sudo apt-get install -y mongodb-org
$ sudo nano /etc/systemd/system/mongodb.service

In the file insert

[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target

[Service]
User=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

[Install]
WantedBy=multi-user.target

Back on the terminal (Ctrl + o and Ctrl + x).

$ sudo systemctl start mongodb
$ sudo systemctl enable mongodb
$ sudo mongo
$ use Farina
$ exit

With MongoDB, Node and NPM correctly installed and updated, we need a node process manager, so that the system functions as a service.

$ npm install -g pm2
$ pm2 startup systemd

A new command will be generated, run as directed by PM2. Copy the system server folder to the server (FTP). In the destination folder I run the system server inside the PM2.

$ pm2 start npm --name "farinaserver" -- run start

The system client does not depend on settings on the server. But eventually you may wish to provide both through the same machine. For this nginx can be useful. Note: The entire system works over the https protocol Installing nginx

$ sudo apt-get install nginx
$ sudo systemctl stop nginx

Installing ssl certificates for nginx

$ sudo apt-get install letsencrypt
$ sudo letsencrypt certonly --standalone

After following the instructions on the screen to create the certificate. Resume the nginx configuration.

$ sudo nano /etc/nginx/sites-available/default

This is sample for configuration. Adjust according to your settings.

server {
  listen 443;

  root /var/www/html;
  index index.html index.htm;

  server_name {SERVER NAME example.com};

  ssl on;
  ssl_certificate /etc/letsencrypt/live/{SERVER NAME example.com}/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/{SERVER NAME example.com}/privkey.pem;
  ssl_session_timeout 30m;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';

  location / {
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
    proxy_pass https://127.0.0.1:4430/;
  }

  location /pepserver/ {
    proxy_pass https://127.0.0.1:3060/;
  }
}

Starting nginx for testing

$ sudo nginx -t
$ sudo systemctl start nginx

(If you want to use apache to serve the client application, you can find a support guide at: Apache HTTPS)

To end import the default database.

Problems, details and tips that can help:

• Ensure that the server address variable in the client application is pointing to the correct location.
