Boby,
mainly in mac , say the way to start /stop couchbase server in terminal (in documentation )
Start Couchbase Server from the terminal on MacOS
cd /Applications/Couchbase\ Server.app
open -a Couchbase\ Server.app
Stop Couchbase Server from the terminal on MacOS
osascript -e 'quit app "Couchbase Server"'
second issue am facing “{eventing_debug_port, 1944}” is saving in static_config but when starting server it takes default static_config (without any debugging port)
Please read the updated documentation at Debugging and Diagnosability | Couchbase Docs
I believe you need the trailing period “.” in your static_config syntax.
