16.6. Management of MySQL Cluster
Managing a MySQL Cluster involves a number of tasks, the first of
which is to configure and start MySQL Cluster. This is covered in
Section 16.4, “MySQL Cluster Configuration”, and
Section 16.5, “Process Management in MySQL Cluster”.
The following sections cover the management of a running MySQL
Cluster.
There are essentially two methods of actively managing a running
MySQL Cluster. The first of these is through the use of commands
entered into the management client whereby cluster status can be
checked, log levels changed, backups started and stopped, and
nodes stopped and started. The second method involves studying the
contents of the cluster log
ndb_node_id
_cluster.log
in the management server's DataDir
directory.
(Recall that node_id
represents the
unique identifier of the node whose activity is being logged.) The
cluster log contains event reports generated by
ndbd. It is also possible to send cluster log
entries to a Unix system log.
