Creating a cluster
Instructions on how to provision a new cluster using OpsCenter.
OpsCenter can provision new Cassandra and DataStax Enterprise clusters. To do this, each node in the cluster must meet the following requirements:
- Have Oracle Java 7 installed.
- Cannot have Cassandra or DSE installed.
- Have a user capable of using
sudo
for local clusters, unless you've configured OpsCenter to not usesudo
(see theruns_sudo
option described in OpsCenter configuration properties). - When provisioning on EC2 nodes, the OpsCenter machine needs access to port 61621 on the managed nodes, and the nodes need access to port 61620 on the OpsCenter machine.
Procedure
Results
The new cluster is now available.
If the agent fails to install, check opscenterd.log and /var/log/datastax-agent/installer.log on the affected nodes. Also verify that the correct ports are open between machines as described in OpsCenter and DataStax agent ports.
If the agent installs successfully, but there is an issue with the Cassandra or DSE setup process, check opscenterd.log, /var/log/datastax-agent/agent.log, /var/log/cassandra/output.log, and /var/log/cassandra/system.log for any errors.
