Setup Nginx

Login and User Setup

  1. SSH into Your Machine: Use an SSH client to log into your server.
ssh your_user@your_server_ip

Update System Packages

Frist, ensure that all packages are up to date. This can prevent security vulnerabilities.

sudo apt update && sudo apt upgrade && sudo apt autoremove

Install Monitoring and Web Server Tools

  1. Install Glances: An advanced system monitor for Linux.
sudo apt install glances
  1. Install Nginx: A high-performance web server and a reverse proxy, often used for load balancing.
sudo apt install nginx
  1. Configure UFW Firewall for Nginx: Make sure Nginx can receive HTTP and HTTPS traffic.
sudo ufw allow 'Nginx HTTP' 
sudo ufw allow 'Nginx HTTPS'

Set Up Nginx Configuration

  1. Remove Existing Nginx Configuration:
sudo rm -rf /etc/nginx/nginx.conf
  1. Edit New Configuration: Use a text editor like nano to create a new configuration file.
sudo nano /etc/nginx/nginx.conf
  • Replace the contents with your load balancer configuration. You can use the example-nginx-config.md as a starting point.
  • Modify RPC/LCD/gRPC server entries and domain names as required.
  • Save and exit the editor (CTRL + X, then Y to confirm, and Enter to save).
  1. Test Nginx Configuration: Ensures your syntax is correct.
sudo nginx -t
  1. Enable and Start Nginx: This will make sure Nginx starts on boot and starts running immediately.
sudo systemctl enable nginx 
sudo systemctl start nginx

Secure with SSL/HTTPS

  1. Install Certbot: This tool automates obtaining free SSL/TLS certificates from Let's Encrypt.
sudo apt-get install certbot python3-certbot-nginx
  1. Obtain the SSL Certificate for your domain:
sudo certbot --nginx -d your_domain.com
  1. Finally, you can add a cronjob to crontab to enable auto-newing of the certificates:
crontab -e
0 12 * * * /usr/bin/certbot renew --quiet
