How to connect to Couchbase server 4.0(Beta) N1QL in windows?

Question

I have just installed Couchbase Server 4.0(beta) and try to run N1QL Query, but could not connect it. When I try to run cbq-engine.exe -couchbase http://localhost:8091/ The command prompt closed automatically. When try to use cb.exe -engine=http://localhost:8091/ It also does not work. Is it bug? How to connect it? (I am running cbq.exe from bin directory of installation)

Answer 1

As documented in the Running your first N1QL query section of the Couchbase Server manual the port the cbq needs to connect to is 8093

cbq.exe -engine=http://localhost:8093

Answer 2

There may be something you missed during installation (it happened to me more than once, and this has been signaled to the team): did you check the "Index" and "Query" checkbox, they are unselected by default, and without it N1QL doesn't run...

See the checkboxes under "Start a new Cluster" in the screenshot below:
