Our Droplet is ready to be used for production, but as you can see, we are still using port 3000. We need to configure nginx and implement a proxy to redirect the traffic from port 80 to 3000; this means we won't need to specify the port directly anymore. Node Production Process Manager (PM2) will help us run the Node server in production securely. Generally, if we run Node directly with the node or babel-node commands, and there is an error in the app, then it will crash and will stop working. PM2 restarts the node server if an error occurs.
First, in your Droplet, you need to install PM2 globally:
npm install -g pm2
PM2 will help us to run our React app in a very easy way.
Installing and configuring nginx
To install nginx, you need to execute the following command:
sudo apt-get update
sudo apt-get install nginx
After you have installed nginx, then you can start the configuration:
- We need to adjust the firewall to allow the traffic for port 80...
