Initializing a DataStax Enterprise cluster
Initializing a DataStax Enterprise (DSE) cluster includes configuring, and choosing how the data is divided across the nodes in the cluster.
cassandra-rackdc.properties
The location of the cassandra-rackdc.properties file depends on the type of installation:| Package installations | /etc/dse/cassandra/cassandra-rackdc.properties |
| Tarball installations | installation_location/resources/cassandra/conf/cassandra-rackdc.properties |
Complete the following tasks before initializing a DSE cluster.
- Establish a firm understanding of how the database works. Be sure to read at least and .
- Ensure the environment is suitable for the use case and workload.
- Review recommended production settings.
- Choose a name for the cluster.
- For a mixed-workload cluster, determine the purpose of each node.
- Determine the snitch and replication strategy. The GossipingPropertyFileSnitch and NetworkTopologyStrategy are recommended for production environments.
- Obtain the IP address of each node.
- Ensure that DataStax Enterprise is installed on each node.
- Determine which nodes are seed nodes. Do not make all
nodes seed nodes.
Seed nodes are not required for DSE Search datacenters, see .
- Review and make appropriate changes to other property files, such as cassandra-rackdc.properties.
- Set virtual nodes correctly for the type of datacenter. DataStax recommends using 8 vnodes (tokens). See Virtual nodes for more information.
