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.
