How to Configure SSL for Apache on Ubuntu 23.10

To configure SSL for Apache on Ubuntu 22.04, you can follow the steps below:

Step 1 : Install OpenSSL:

If OpenSSL is not already installed, you can install it using the following command:

sudo apt update
sudo apt install openssl

Step 2 : Enable the SSL Module for Apache:

sudo a2enmod ssl

Step 3 : Generate a Private Key and Certificate Signing Request (CSR):

Run the following command to generate a private key and a CSR:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/example.com.key -out /etc/ssl/certs/example.com.crt

Replace example.com with your actual domain.

You will be prompted to provide information for the certificate.

Step 4 : Configure Apache to Use SSL:

Edit your Apache configuration file to include the SSL certificate and key:

sudo nano /etc/apache2/sites-available/example.com-le-ssl.conf

Add or modify the SSL configurations like this:

<VirtualHost *:443>
    ServerName example.com
    DocumentRoot /var/www/example.com

    SSLEngine on
    SSLCertificateFile /etc/ssl/certs/example.com.crt
    SSLCertificateKeyFile /etc/ssl/private/example.com.key

    # Other SSL-related configurations can be added here

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Step 5 : Enable the SSL Virtual Host:

Enable the SSL virtual host configuration:

sudo a2ensite example.com-le-ssl.conf

Step 6 : Restart Apache:

Restart the Apache service to apply the changes:

sudo systemctl restart apache2

Step 7 : Verify SSL Configuration:

Visit your website using https://example.com in a web browser. Since this is a self-signed certificate, you may see a security warning. This is normal for self-signed certificates, and you can proceed to the site.

Congratulations, you have successfully configured SSL for Apache on Ubuntu 22.04!
