Cassandra multi node setup script for single host

Primary LanguageShell

Cassandra multi node setup script for single host.

Tested cassandra 1.2.3 on Ubuntu 12.0x only

The script make nodes as follows:

node 1: address=127.0.0.1, jmx port=7199
node 2: address=127.0.0.2, jmx port=7200
node 3: address=127.0.0.3, jmx port=7201

Preparation (only OSX)

Create interface aliases you need

sudo ifconfig lo0 alias 127.0.0.2 up
sudo ifconfig lo0 alias 127.0.0.3 up

  2. clone this.

  $ git clone https://github.com/ksauzz/cassandra-multi-node.git
  $ cd cassandra-multi-node
  1. create nodes.
  $ ./multi-node.sh create 3 cassandra_home
  1. start cassandra multi-node.
  $ ./multi-node.sh start_all
  1. show ring status.
  $ nodes/1/bin/nodetool ring
