Sails.js is a Node.js framework designed for building practical, production-ready applications. It’s especially good for building data-driven APIs and web applications. In this guide, we will walk through the steps to install Sails.js on CentOS 8 and set it up with Nginx.

Step 1: Update Your System

Start by ensuring your system is up to date:

sudo dnf update -y

Step 2: Install Node.js

Sails.js requires Node.js. Install Node.js using the following commands:

curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -
sudo dnf install -y nodejs

Step 3: Install Sails.js

Once Node.js is installed, you can install Sails.js globally using npm:

sudo npm install -g sails

Step 4: Create a New Sails Application

Create a new Sails application using the following command:

sails new myApp

Replace myApp with your desired application name.

Step 5: Change Directory and Start the Application

Navigate into your application directory and start Sails:

cd myApp
sails lift

By default, Sails runs on port 1337. You can test your application by visiting http://your_server_ip:1337 in your browser.

Step 6: Install and Configure Nginx

Install Nginx using the following command:

sudo dnf install -y nginx

Once installed, configure Nginx to act as a reverse proxy for your Sails application. Open the default configuration file:

sudo nano /etc/nginx/nginx.conf

Add the following server block to the configuration file:

server {
        listen 80;
        server_name your_server_ip; # Replace with your server's IP or domain

        location / {
            proxy_pass http://localhost:1337;
            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;
        }
    }

Step 7: Start and Enable Nginx

Start the Nginx service and enable it to run at boot:

sudo systemctl start nginx
sudo systemctl enable nginx

Step 8: Adjust the Firewall

If you have a firewall enabled, allow HTTP traffic:

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --reload

You have successfully installed Sails.js on CentOS 8 and configured Nginx to serve your application. This setup will help you build and deploy your applications effectively.
