Setting Node.JS on Ubuntu

info.txt

**Install Node.js**

cd ~
curl -sL https://deb.nodesource.com/setup_8.x -o nodesource_setup.sh
sudo bash nodesource_setup.sh
sudo apt-get install nodejs
sudo apt-get install build-essential

**Install Nginx**
sudo apt-get update
sudo apt-get install nginx

**Adjust the Firewall**
sudo ufw app list    -- to list all available apps
Nginx Full: This profile opens both port 80 (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted traffic)
Nginx HTTP: This profile opens only port 80 (normal, unencrypted web traffic)
Nginx HTTPS: This profile opens only port 443 (TLS/SSL encrypted traffic)
sudo ufw allow 'Nginx Full'

**Manage the Nginx Process**
sudo systemctl stop nginx
sudo systemctl start nginx
sudo systemctl restart nginx
sudo systemctl reload nginx


**Set Up Nginx as a Reverse Proxy Server**
sudo nano /etc/nginx/sites-available/default
. . .
    location / {
        proxy_pass http://localhost:8080;
        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;
    }
}

**Check Nginx syntax**
sudo nginx -t
sudo systemctl restart nginx
