How to change Couchbase Web Console Port?

Hello…
Can I know how to change Couchbase Web Console Port?
8091 -> 30000

Yes can change the Administration Console port (8091) using the CLI:

./couchbase-cli cluster-init -c localhost:8091 -u Administrator -p password --cluster-init-port=9090

You can also change the port of your bucket
You can find all the commands and parameters in the chapter ‘couchbase-cli Tool’:
http://docs.couchbase.com/couchbase-manual-2.0/#couchbase-cli-tool

AFAIK it is not possible to change the view port 8092.

Thanks,
D
