Let’s get started.
Step 1: Backup Your Current Configuration
Before making any changes to your server, it’s always a good practice to backup your current configurations. This ensures that you can revert to the previous state if something goes wrong.
Navigate to the directory where your SSL certificates are stored.
cd /etc/ssl/certs
Create a backup of the Cloudflare Origin CA certificate.
sudo cp cloudflare_origin.pem cloudflare_origin_backup.pem
Step 2: Identify and Stop Services Using the Certificate
To safely uninstall the certificate, first identify which services are using it.
Use the lsof command to identify services using the Cloudflare certificate.
lsof /etc/ssl/certs/cloudflare_origin.pem
Stop the services identified. For instance, if Apache is using the certificate:
sudo systemctl stop apache2
Step 3: Remove the Cloudflare Origin CA Certificate
With the services stopped, you can now safely remove the certificate.
Navigate to the SSL directory.
cd /etc/ssl/certs
Delete the Cloudflare Origin CA certificate.
sudo rm cloudflare_origin.pem
Step 4: Update Your Web Server Configuration
After removing the certificate, update your web server configuration to either use a different certificate or run without SSL.
For Apache, edit the configuration file.
sudo nano /etc/apache2/sites-available/your_site.conf
Locate the SSLCertificateFile directive and either comment it out or replace the path with a new certificate.
Save and exit the editor.
Restart the web server to apply changes.
sudo systemctl restart apache2
Step 5: Verify the Uninstallation
Ensure that the certificate has been successfully removed and that your web server is functioning correctly.
Check the SSL directory to confirm the certificate’s removal.
ls /etc/ssl/certs
Access your website and verify that it’s running without the Cloudflare Origin CA or with the new certificate.
