Testing the connection to the Couchbase Server can be performed in a number of different ways. Connecting to the node using the web client to connect to the admin console should provide basic confirmation that your node is available. Using the couchbase-cli command to query your Couchbase Server node will confirm that the node is available.
The Couchbase Server web console uses the same port number as clients use when communicated with the server. If you can connect to the Couchbase Server web console, administration and database clients should be able to connect to the core cluster port and perform operations. The Web Console will also warn if the console loses connectivity to the node.
To verify your installation works for clients, you can use either the cbworkloadgen command, or telnet. The cbworkloadgen command uses the Python Client SDK to communicate with the cluster, checking both the cluster administration port and data update ports. For more information, see Section 2.5.1, “Testing Couchbase Server using cbworkloadgen”.
Using telnet only checks the Memcached compatibility ports and the memcached text-only protocol. For more information, see Section 2.5.2, “Testing Couchbase Server using Telnet”.
