How to install Jitsi along with recording capabilities?

I followed this guide where Jitsi is installed fine but without recording capabilities.

I’m aware that recordings are managed by another component, but I want to record one session at a time. No cuncurrent meetings would happen. How can I install Jitsi along with recording capabilities. And also, after installing Jibri, how configure jibri with existing jitsi server?

You actually did a quick install… like https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md , which is more convenient.
you could also install all component manually from https://github.com/jitsi/jitsi-meet/blob/master/doc/manual-install.md and get a good understanding about the architecture and components.
For jibri, after installing jitsi you need to follow https://github.com/jitsi/jibri and install+configure
