4. ufw app list
5. ufw allow OpenSSH
6. ufw enable
7. ufw status
8. ssh username@your_server_ip

DNS to server public IP

NGINX Setup

1. sudo apt update
2. sudo apt install nginx
3. sudo ufw app list
4. sudo ufw allow 'Nginx HTTP'
5. sudo ufw status
6. sudo systemctl status nginx
7. sudo systemctl stop nginx
8. sudo systemctl start nginx
9. sudo systemctl restart nginx
10. sudo systemctl reload nginx
11. sudo systemctl disable nginx
12. sudo systemctl enable nginx

Secure NGINX

1. sudo add-apt-repository ppa:certbot/certbot
2. sudo apt install python-certbot-nginx
3. sudo nano /etc/nginx/sites-available/default
4. server_name domain.com www.domain.com;
5. sudo nginx -t
6. sudo systemctl reload nginx
7. sudo ufw status
8. sudo ufw allow 'Nginx Full'

10. sudo ufw status
11. sudo certbot --nginx -d domain.com -d www.domain.com
12. Let’s Encrypt’s certificates are only valid for ninety days. This is to encourage users to automate their certificate renewal process. The certbot package we installed takes care of this for us by adding a renew script to /etc/cron.d.
13. sudo certbot renew --dry-run

Multiple subfolders running different applications

1. sudo nano /etc/nginx/sites-available/default

2. ` index index.html server_name domain.com www.domain.com location / { try_files $uri $uri/ = 404; } location /hello/ { 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; }

   `

3. sudo nginx -t

4. sudo systemctl restart nginx

Multiple domains as server blocks

1. sudo mkdir -p /var/www/example.com/html
2. sudo chown -R $USER:$USER /var/www/example.com/html
3. sudo chmod -R 755 /var/www/example.com
4. nano /var/www/example.com/html/index.html
