Installing and Configuring Node.js, PM2, and NGINX on Linux

In this tutorial, we will be going through the steps to install and configure Node.js, PM2, and NGINX on a Linux system.

Step 1: Install NVM (Node Version Manager)

curl -o- <https://raw.githubusercontent.com/creationix/nvm/v0.35.3/install.sh> | bash

nvm --version

Step 2: Install Git

yum install git -y

Step 3: Install Node.js using NVM

nvm install node

Step 4: Clone Repo

git clone https://github.com/Sanjai-R/Nodeapp_niginx.git

Step 5: Install packages

Step 6: Install PM2

npm install pm2 -g

Step 7: Start your Node.js application using PM2

pm2 start index.js

Step 8: Install NGINX

sudo yum install nginx -y

Step 9: Modify NGINX configuration files

location / {
    proxy_pass <http://localhost:3000>;
    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 10: Configure NGINX as a reverse proxy for your Node.js application

In the NGINX configuration file, add a server block for your Node.js application. Within this block, add the following lines:

location / {
    proxy_pass <http://localhost:3000>;
    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;
}

Then, restart NGINX to load the new configuration:

sudo systemctl restart nginx

Your Node.js application should now be accessible through NGINX at your server's IP address or domain name.
