To deploy a Node.js application on a VPS, you will need to follow these steps:
-
Set up and configure your VPS. This usually involves installing an operating system (such as Ubuntu or CentOS), setting up a non-root user with sudo privileges, and configuring the firewall to allow incoming connections to the Node.js application.
-
Install Node.js. Follow the instructions provided in the Node.js documentation to install Node.js and its dependencies on your VPS.
-
Install and configure a web server. Node.js applications can be deployed using a variety of web servers, such as Apache or Nginx. Follow the instructions provided by the web server's documentation to install and configure it on your VPS.
-
Deploy your Node.js application. To deploy your Node.js application on your VPS, you will need to copy the application files to your VPS and start the application using Node.js. You may also need to set up a process manager (such as PM2) to keep the application running in the background.
-
Test your Node.js application. Access your Node.js application using your web browser and ensure that it is functioning correctly.
-
Set up a production-ready deployment. For a production-ready deployment, you may want to consider setting up a load balancer to distribute incoming requests among multiple servers, setting up a reverse proxy (such as Nginx) to handle incoming requests, and deploying your application in a "high-availability" configuration using tools such as Docker or Kubernetes.
Note: The specific steps for deploying a Node.js application on a VPS may vary depending on your operating system, web server software, and Node.js version. If you run into any issues or have any questions, it is a good idea to consult the Node.js documentation or a qualified system administrator for assistance.
