Set up Multi node Cassandra3.6 Cluster on Ubuntu 16.04

In the below example i’m using 3 nodes with the below IP’s.Each of them have Single node cassandra cluster already set up in it.

Node1: 172.16.167.176
Node2: 172.16.167.132
Node3: 172.16.167.185
Through the below simple steps im trying to set up the nodes to function as a multi node cassandra cluster, so please run the below steps in all of your available nodes on your cluster.

Step1:Stop Cassandra daemon & delete the default data set

$ sudo service cassandra stop
$ sudo rm -rf /var/lib/cassandra/data/system/

Step2:COnfigure the cassandra cluster using the configuration file

$ sudo vim /etc/cassandra/cassandra.yaml

cluster_name: 'CassandraDOCluster'

seed_provider:

• class_name: org.apache.cassandra.locator.SimpleSeedProvider
  parameters:
  - seeds: "172.16.167.176,72.16.167.132,72.16.167.185"
  listen_address: 172.16.167.176
  rpc_address: 172.16.167.176
  endpoint_snitch: GossipingPropertyFileSnitch
  auto_bootstrap: false

Step3:Start cassndra server & check status

$ sudo service cassandra start
$ sudo nodetool status

Step4:Log into your node’s CQL console and try to make some changes in your Db tables just to check those changes are reflecting in your other nodes too.

$ cqlsh 172.16.167.176 9042

You are done.

Note: You can log into the CQL console and check the db changes you makes are reflecting in your other nodes instantly..
