This tutorial has been verified to work with Debian 9 Stretch. Any Debian 9 derivatives should also works. Open Terminal or connect to Debian 9 via SSH and execute these commands below:
Fix: “You are accessing this site via HTTP. We strongly suggest you configure your server to require using HTTPS instead as described in our security tips.”
In this post we will learn, how to enable and configure SSL on ownCloud installation.
Enable SSL on Raspberry PI Owncloud
Step 1: Enable SSL, Open the terminal and run the following command:
sudo a2enmod ssl
Step 2: Create a new directory for the self signed certificate
sudo mkdir /etc/apache2/ssl
Step 3: Create the self signed certificate and the server key that protects it, and placing both of them into the new directory
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/owncloud.key -out /etc/apache2/ssl/owncloud.crt
Note: The above certificate is valid for 365 days. We have mentioned validity days in the command.
Step 4: Now we need to setup the certificate
sudo nano /etc/apache2/sites-available/default-ssl.conf
The lines that need changing are the following
ServerName LAN IP :443
Once the lines has been modified Exit and save.
Step 5: Activate the new virtual host
sudo a2ensite default-ssl
Step 6: Restart apache
sudo service apache2 restart
Step 7: If prompted the Apache2 could not reliably determine the server’s fully qualified domain name:
echo "ServerName localhost" | sudo tee /etc/apache2/conf-available/fqdn.co
The Enable SSL on Raspberry PI Owncloud video tutorial applies for Ubuntu, Linux and Raspbian. I have tested this my self.
