Creating a cluster and nodes<\/strong><\/h3>\n

To configure multi node setup do the following :<\/strong><\/p>\n

Step 1. Locate Cassandra.yaml and search for \u2018seed\u2019. Change the IP address to the IP Address of any one node whom you want to designate as \u2018seed\u2019 (more on seed later).<\/p>\n

Step 2. Change listen_address to local IP (should not be 127.0.0.1)<\/p>\n

Step 3. Change rpc_address to local IP (should not be 127.0.0.1) Repeat the configuration changes for all the nodes and run this command to verify :<\/p>\n

(note : x\u2019s are just used to hide real IP-Addresses),<\/p>\n

Adding other nodes<\/strong>
\nSimply copy the Apache Cassandra folder of first node to each of these. Now replace the listen_address: <node IP address> and rpc_address: <node IP address> as relevant for each node. (No need to touch seeds section) When we start each node now it will join the ring, using the seeds as hubs of the gossip network. In the logs it will show up the information related to other nodes in the cluster as it can see.<\/p>\n
