Once you have installed Cockpit, start and enable it using the following commands.

sudo systemctl enable --now cockpit.socket

Configure firewall

Run the following commands to allow all of the required ports through the firewall.

sudo firewall-cmd --permanent --zone=public --add-service=cockpit

You may be prompted with a security warning about the SSL certificate of the site as it is self-signed, but you can ignore the warning and proceed to login area. Log into Cockpit using the root credentials of your VPS.

Installing new SSL certs

In order to use SSL certificates you need to combine them into one file in the following location with the cert file ending in .cert. The public key should be first, then the private.

ls /etc/cockpit/ws-certs.d

It should look something like this.

cat /etc/cockpit/ws-certs.d/ssl.cert
