How do I connect to Cassandra database remotely?

You can try these steps to test this out:

  1. 1) Ensure you can connect to that IP from the server you are on: $ ssh [email protected].
  2. 2) Check the node’s status and also confirm it shows the same IP: $nodetool status.
  3. 3) Run the command to connect with the IP (only specify the port if you are not using the default):

What is RPC stands for?

Stands for “Remote Procedure Call.” Most computer programs run procedures, or sets of instructions, using the computer’s CPU.

Where is Cqlsh located?

bin/ directory
cqlsh is a command-line interface for interacting with Cassandra using CQL (the Cassandra Query Language). It is shipped with every Cassandra package, and can be found in the bin/ directory alongside the cassandra executable.

What is the default listen port for Cassandra in Python?

In Cassandra 2.1, which uses the Datastax python driver, the default cqlsh listen port is 9042. The cassandra node should be bound to the IP address of your server’s network card – it shouldn’t be 127.0.0.1 or localhost which is the loopback interface’s IP, binding to this will prevent direct remote access.

How to bind the Cassandra node to the loopback interface?

The cassandra node should be bound to the IP address of your server’s network card – it shouldn’t be 127.0.0.1 or localhost which is the loopback interface’s IP, binding to this will prevent direct remote access. To configure the bound address, use the rpc_address parameter in cassandra.yaml.

How do I enable thrift in Cassandra?

By default, Cassandra 2.0.x and earlier enables Thrift by configuring start_rpc to true in the cassandra.yaml file. In Cassandra 2.1, the cqlsh utility uses the native protocol. In Cassandra 2.1, which uses the Datastax python driver, the default cqlsh listen port is 9042.
