<VirtualHost *:443>
    ServerAdmin admin@example.com
    DocumentRoot /var/www/html
    ServerName thebigocommunity.org
    ServerAlias www.thebigocommunity.org
  
    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/thebigocommunity.org/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/thebigocommunity.org/privkey.pem
    
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    <Directory /var/www/html>
        Options Indexes FollowSymLinks

Once you have a virtual host file that meets your requirements, you can use the tools included with Apache to transition it into live websites. To create a symbolic link in the sites-enabled directory to an existing file in the sites-available directory, issue the following command. Make sure to replace your_domain with the name of your own virtual host site configuration file:

sudo a2ensite your_domain
