Install SSL on Ipv4 EC2 Ubuntu

Install Certbot: Certbot is a tool provided by Let's Encrypt to automate the process of installing SSL certificates.

sudo apt-get update
sudo apt-get install certbot

**Stop Apache: ** Before obtaining the SSL certificate, it's good to stop Apache temporarily to avoid any conflicts.

sudo systemctl stop apache2

Obtain SSL Certificate: Use Certbot to obtain a certificate for your server.

sudo certbot certonly --standalone -d your_public_ip

Follow the Prompts: Certbot will ask you for an email address and agree to the terms of service.

Configure Apache: Now, you need to configure Apache to use the SSL certificate. Open the Apache configuration file:

sudo nano /etc/apache2/sites-available/000-default.conf

Inside the VirtualHost block, add the following lines:

<VirtualHost *:443>
    ServerName your_public_ip
    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/your_public_ip/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/your_public_ip/privkey.pem
</VirtualHost>

Enable SSL Module and Site: Enable the SSL module and your site configuration.

sudo a2enmod ssl
sudo a2ensite default-ssl

Restart Apache: Restart Apache to apply the changes.

sudo systemctl restart apache2

Hello

Generally, it is only possible to use an SSL certificate with a domain name. I think this is because it is difficult to verify the ownership of the IP.

Technically, it is possible, and some vendors may sell such certificates, but I do not know of any.

If you only need to use it, you can issue your certificate.
