How to Configure SSL for Apache on Ubuntu 23.04

To configure SSL for Apache on Ubuntu 23.04, follow these steps:

Step 1 : Update:

Begin by ensuring your system is up to date. Run the following command in the terminal:

sudo apt update && sudo apt upgrade

Step 2 : Install OpenSSL:

If OpenSSL is not already installed, you can do so with the following command:

sudo apt install openssl

Step 3 : Generate SSL:

Generate a self-signed SSL certificate using OpenSSL. Replace "example.com" with your domain:

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

Step 4 : Create Apache Configuration File

Create a new Apache configuration file for your domain. Open the configuration file in a text editor:

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

Add the following lines within the <VirtualHost> block:

<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
</VirtualHost>

Step 5 : Enable SSL module:

Enable the SSL module for Apache:

sudo a2enmod ssl

Step 6 : Enable SSL Configuration:

sudo a2ensite example.com-ssl.conf

Step 7 : Test Configuration:

Check the Apache configuration for any syntax errors:

sudo apache2ctl configtest

Step 8 : Restart Apache:

Restart the Apache service to apply the changes:

sudo systemctl restart apache2

Step 9 : Check Results:

Navigate to your domain (https://example.com) in a web browser and ignore any warnings.

Congratulations! You have successfully configured SSL for Apache on Ubuntu 23.04. Your website is now secured with SSL encryption.
