Configuration of NDB Cluster to that displayed during cluster startup, shows the approximate current status of the cluster shutdown procedure, as do the process status icons adjoining the process tree. The progress bar is shown here: Figure 23.24 Cluster Shutdown Process, with Progress Bar Figure 23.25 Cluster Shutdown, Process Completed Dialog A confirmation dialog indicates when the shutdown process is complete: The Auto-Installer generates a  config.ini  file containing NDB node parameters for each management node, as well as a  my.cnf  file containing the appropriate options for each  mysqld  process in the cluster. No configuration files are created for data nodes or API nodes. A MySQL server that is part of an NDB Cluster differs in one chief respect from a normal (nonclustered) MySQL server, in that it employs the  NDB  storage engine. This engine is also referred to sometimes as NDBCLUSTER , although  NDB  is preferred. To avoid unnecessary allocation of resources, the server is configured by default with the  NDB  storage engine disabled. To enable  NDB , you must modify the server’s  my.cnf  configuration file, or start the server with the  --ndbcluster  option. 4028 23.3 Configuration of NDB Cluster
