Setting Up and Verifying ZeroSSL for CyberPanel Hostname SSL
1. Obtain and Download ZeroSSL Files
- Generate an SSL certificate for your CyberPanel hostname (e.g.,
host.yourdomain.com) using ZeroSSL. - Once the certificate is issued, download these files:
- private.key – your private key file
- certificate.crt – the main certificate
- ca_bundle.crt – CA bundle with intermediate certificates
2. Upload the Certificate Files to Your Server
- Transfer these files to your server, ideally placing them in
/root/zerossl/.
3. Backup Existing Hostname SSL Files
- To avoid losing the current SSL setup, make a backup of the existing CyberPanel hostname SSL files:
bash
Copy code
mkdir -p /etc/letsencrypt/live/host.yourdomain.com/backup/
cp /etc/letsencrypt/live/host.yourdomain.com/*.pem /etc/letsencrypt/live/host.yourdomain.com/backup/
4. Replace Existing SSL Files with ZeroSSL Files
- Copy the downloaded ZeroSSL files to the necessary directory, renaming them to match the expected filenames:
bash
Copy code
cp /root/zerossl/private.key /etc/letsencrypt/live/host.yourdomain.com/privkey.pem
cp /root/zerossl/certificate.crt /etc/letsencrypt/live/host.yourdomain.com/cert.pem
cp /root/zerossl/ca_bundle.crt /etc/letsencrypt/live/host.yourdomain.com/fullchain.pem
5. Restart CyberPanel and OpenLiteSpeed
- Restart CyberPanel and OpenLiteSpeed to apply the new SSL configuration:
bash
Copy code
systemctl restart lscpd
systemctl restart lsws
6. Verify the SSL Installation
- Access CyberPanel at
https://host.yourdomain.com:8090to ensure it’s using the new ZeroSSL certificate. Check the browser’s SSL information to confirm the certificate details.
This guide provides a clear, general explanation for replacing the CyberPanel hostname SSL with a ZeroSSL certificate, suitable for any hostname. Let me know if there’s anything more to add!
