Open Couchbase Ports on Firewall

Couchbase server uses various TCP ports for network communication. If you are running a system level or edge firewall, be sure to open these ports where necessary.

ufw allow to any port 369,8091:8094,9100:9105,9998,9999,11209:11211,11214,11215,18091:18093,21100:21299 proto tcp comment "Couchbase TCP ports"

You can as well use iptables if you want.

Access the Couchbase Web Console

In my setup, I don’t have an existing cluster. Hence, I will create a new one. Hence, enter the name of the cluster, admin username and password.

install Couchbase Server on Debian 11/Debian 10

Next, accept the EULA and choose whether to setup disk, ram and services or finish with defaults. We choose finish with defaults in this setup.
