ESP uses a database-based cluster configuration, rather
than a file-based cluster configuration. This database hosts configuration information for
the cluster and is known as the cluster database. Several necessary components for the
database-based configuration are installed during installation.
Cluster Database
- When the ESP server is
installed,
the installer creates the cluster database.
- The installer also deploys an initial cluster configuration consisting of a
single node.
Passwords
- The installer prompts you for the cluster database user name and password. The credentials
you define here need not belong to an actual user, but are required for
administrative-level access to this database.
- The installer prompts you for the cluster password – this is also used as the password for
the SYS_STREAMING user, which is used for
logging into ESP Cockpit immediately after
installing ESP .
File and Script Updates
- The installer updates settings in the cluster bootstrap file
(cluster.cfg).
- The installer updates the script used to start the cluster database
.
- The installer updates the script used to start the initial
node.
