Config.json are not available after installing the jibri,only jibri.conf is available

I didnot get it.So recording is also saying Recording is unavailable.

config.json is being deprecated and does not come with new jibri installations. You need to configure jibri.conf instead. Take a look at the Jibri.conf section in this tutorial on how to do that - TUTORIAL - How to Install the NEW JIBRI

Thank You.It Works.Can you guide me how to do recording simultaneously with different users at a time.??

Jibri can only do one recording at a time. You need an instance of Jibri for every recording you want to do.

Yes I know i need multiple jibri for that. But i want to know if I installed another jibri server then how to configure that 2nd jibri server with the main jitsi server.??
