To provision a NuoDB host:
Install NuoDB software on the host you want to add to the domain.
See Installing NuoDB for installation instructions on your platform. For the purpose of scaling out a domain by adding another host, make sure to defer automatic start of NuoDB services until you have configured the local properties in the next step.
After installing the software, edit the new host's
NUODB_HOME /etc/default.properties file. The
domainPassword properties are required. For descriptions of the more frequently used properties, see Setting Host Properties When Provisioning Hosts. For a full reference of all available properties, see Host Properties (default.properties).
Start the broker.
See Starting and Stopping NuoDB Services. The
nuoagent service is the broker process. Consider configuring the service to automatically start.
Verify that the host peered into the domain.
To do this, you can use the Automation Console, the NuoDB Manager utility, or the REST API. In the Automation Console, click Hosts in the left panel to see if the new host is listed. For example:
To use NuoDB Manager, invoke the
show domain hosts command. For example:
nuodb [domain] >
show domain hosts[broker] * ec2-54-173-96-113.compute-1.amazonaws.com/172.31.14.118:48004 (us-east-1) [broker] ip-172-31-46-122/184.108.40.206:48004 (us-east-1)
To use the REST API, specify the
hosts resource. For example:
