From Code to the Cloud:

A Step-by-Step Guide to Deploying Your Node.js App on AWS EC2 II

The part one dealt with the following:

1. Setting up an AWS account


2. Creating an EC2 instance


3. Installing Node.js and NPM


4. Creating a simple Node.js app


5. Installing and configuring PM2


6. Using SSH to connect to your EC2 instance


7. Deploying your app to the EC2 instance

Read the part one

Install the Nginx reverse proxy

ssh into your EC2 instance

ssh -i "your.pem" ubuntu@<your-ec2>

sudo su - # to get root access

Install nginx

sudo apt-get update

sudo apt-get install nginx

check if nginx is installed

nginx -v  #nginx version: nginx/1.18.0 (Ubuntu)

start nginx

sudo service nginx start

check if nginx is running

sudo service nginx status

Installing Core from Snap

This is a snap package that provides the core functionality of snapd and the snap command-line tool. It is required to install other snaps.

sudo snap install core; 

sudo snap refresh core

Remove Certbot if it's already installed

sudo apt remove certbot

Install Certbot

sudo snap install --classic certbot

Create a symbolic link

sudo ln -s /snap/bin/certbot /usr/bin/certbot

change the following lines to the server block

server {

    listen 80;

    server_name mysubdomain.com; # replace with your domain name



    location / {

        proxy_pass http://localhost:5000; # replace with your app's port

        proxy_set_header Host $host;

        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_set_header X-Forwarded-Proto $scheme;

    }

}

Check status and reload nginx

sudo nginx -t

sudo systemctl reload nginx

Run Certbot (obtain free ssl)

sudo certbot certonly --nginx -d mysubdomain.com

Verify certbot renewal

sudo systemctl status snap.certbot.renew.service

Enable automatic renewal

sudo certbot renew --dry-run

Conclusion

By following these steps, you can easily set up a subdomain on your server and obtain a free SSL certificate using Certbot. This will help you secure your website and improve its performance.
