Tutorial: Run Gatsby on VPS?

Running Gatsby on a Virtual Private Server (VPS) allows you to host your Gatsby website on a remote server rather than using shared hosting or deploying it to a platform like Netlify or Vercel. Deploying Gatsby on a VPS gives you more control over the hosting environment and allows you to handle higher traffic loads.

To run Gatsby on a VPS, you would typically follow these steps:

1. Choose a VPS provider: Select a VPS provider that meets your requirements. Popular options include DigitalOcean, Linode, and AWS EC2. Sign up for an account and create a new VPS instance.
2. Set up the server: Once your VPS instance is created, you need to log in to the server via SSH. Install all the necessary software like Node.js, Git, and any other dependencies required by your Gatsby project.
3. Clone your Gatsby project: On the VPS, navigate to the desired directory where you want to host your Gatsby website. Clone your project repository from a version control system like Git.
4. Install dependencies: Inside your Gatsby project directory, run the command npm install to install all the project dependencies.
5. Build the Gatsby website: Run the command gatsby build to build your Gatsby website. This generates the static HTML, CSS, and JavaScript files required for your site.
6. Set up a web server: Configure a web server, such as Nginx or Apache, to serve the static files generated by Gatsby. Point the server to the build output directory generated in the previous step.
7. Configure DNS settings: Associate your domain name with the IP address of your VPS by updating your domain's DNS settings. This allows visitors to access your Gatsby website using your custom domain.
8. Test and deploy: Restart the web server and test your Gatsby website by accessing it through a web browser. If everything looks good, you have successfully deployed Gatsby on a VPS.

Running Gatsby on a VPS requires some technical expertise, but it provides greater flexibility and control over your hosting environment. It is a suitable option for projects with specific requirements or higher traffic demands.
