duplicate relay when a new relay is started

[sridattasp]

I followed the steps mentioned in document and started a relay with below command
$GOPATH/bin/influxdb-relay -config relay.toml
Relay started successfully

Now, I want to stop the above relay and update relay.toml and start relay with new config. How do I do that?

Since I didnt find a way to stop relay, I again started a new relay which is giving me an error 'duplicate-relay'

How to handle such usecase?
