Introduction

This is a mini-howto for changing the web server certificate in Proxmox, so that you can have a certificate created with a custom CA. It has been tested on a Proxmox VE 3.0 installation, using certificates from https://www.cacert.org/.

HTTPS Certificate Configuration

3 files are needed:

ca.pem : CA certificate file in PEM format
server.key : non-password protected private key
server.pem : server certificate from CA in PEM format

You can create the previous files following any standard openssl certificate generation HOWTO.

Backup PVE created files

cp /etc/pve/pve-root-ca.pem   /etc/pve/pve-root-ca.pem.orig
cp /etc/pve/local/pve-ssl.key /etc/pve/local/pve-ssl.key.orig
cp /etc/pve/local/pve-ssl.pem /etc/pve/local/pve-ssl.pem.orig

Copy your own certificates

cp server.key /etc/pve/local/pve-ssl.key
cp server.pem /etc/pve/local/pve-ssl.pem
cp ca.pem     /etc/pve/pve-root-ca.pem

Using intermediate certificates

Using intermediate certificates requires a special pve-ssl.pem which has to contain both your server.pem and the intermediate_certificate.pem. This must be created this way:

cat server.pem intermediate_certificate.pem > /etc/pve/local/pve-ssl.pem
cat intermediate_certificate.pem ca.pem > /etc/pve/pve-root-ca.pem

After restarting pveproxy and pvedaemon you can verify that pve-ssl.pem is created the proper way by visiting this URL SSL Certificate Tester

If everything is properly configured you will be rewarded with something similarly as can be seen in the image.

Restart the API server and pvedaemon

service pveproxy restart
service pvedaemon restart

That's it.

If you have a Proxmox cluster, this has to be done on all nodes (only the /etc/pve/local part). To test the changes in one node before changing configuration in other nodes, please make sure you log in the web interface in the correct node.
