This document summarizes the steps to set up a Cassandra cluster for a meetup event. It covers installing and configuring Cassandra and DataStax Agent on multiple nodes across two data centers, initializing the schema, inserting sample data, and demonstrates how the cluster handles node and data center failures through replication and hinted handoff. Key steps include configuring IP addresses, Cassandra properties for the cluster, replication strategy, and monitoring the cluster status through nodetool and OpsCenter as nodes are added and removed.
