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

2. Install Nginx: A high-performance web server and a reverse proxy, often used for load balancing.

sudo apt install nginx

3. 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

2. 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 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).

3. Test Nginx Configuration: Ensures your syntax is correct.

sudo nginx -t

4. 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 
sudo apt-get install python3-certbot-nginx

2. Obtain the SSL Certificate for your domain:

sudo certbot --nginx -d your_domain.com

3. Finally, you can add a cronjob to crontab to enable auto-newing of the certificates:

crontab -e
0 12 * * * /usr/bin/certbot renew --quiet
