Efficient SSL Certificate Management in Proxmox: A Comprehensive Guide

The process of installing an SSL certificate on Proxmox ensures data privacy and confidentiality by obtaining a certificate from a trusted authority, uploading it, and configuring the host accordingly.

a) How do I manually change a certificate in Proxmox ?

1. First, log in to Proxmox Backup via SSH or enter the openssl req -newkey rsa:2048 -nodes -keyout key.pem -out req.pem command console.

2. Then, follow these instructions:

3. After that, enter the cp key.pem /etc/proxmox-backup/proxy.key and cp cert.pem /etc/proxmox-backup/proxy.pem commands to activate the new certificate.

4. Finally, enter the systemctl restart proxmox-backup-proxy command to restart the API server and test the new certificate in the browser.

Note: To transfer files to or from Proxmox backup, use safety copies, the scp command-line tool for Linux desktops, or WinSCP for Windows desktops, respectively.
