Installing NDB Cluster on Windows Node 2: starting (Last completed phase 4) (mysql-8.0.26-ndb-8.0.26) Node 3: starting (Last completed phase 4) (mysql-8.0.26-ndb-8.0.26) Node 2: Started (version 8.0.26) Node 3: Started (version 8.0.26) ndb_mgm> Note Commands issued in the management client are not case-sensitive; we use uppercase as the canonical form of these commands, but you are not required to observe this convention when inputting them into the  ndb_mgm  client. For more information, see Section 23.5.1, “Commands in the NDB Cluster Management Client” . The output produced by  ALL STATUS  is likely to vary from what is shown here, according to the speed at which the data nodes are able to start, the release version number of the NDB Cluster software you are using, and other factors. What is significant is that, when you see that both data nodes have started, you are ready to start the SQL node. You can leave  ndb_mgm.exe  running; it has no negative impact on the performance of the NDB Cluster, and we use it in the next step to verify that the SQL node is connected to the cluster after you have started it. 4. On the computer designated as the SQL node host, open a console window and navigate to the directory where you unpacked the NDB Cluster binaries (if you are following our example, this is  C: \mysql\bin ). Start the SQL node by invoking  mysqld.exe  from the command line, as shown here: C:\mysql\bin>  mysqld --console The  --console  option causes logging information to be written to the console, which can be helpful in the event of problems. (Once you are satisfied that the SQL node is running in a satisfactory manner, you can stop it and restart it out without the  --console  option, so that logging is performed normally.) In the console window where the management client ( ndb_mgm.exe ) is running on the management node host, enter the  SHOW  command, which should produce output similar to what is shown here: ndb_mgm>  SHOW Connected to Management Server at: localhost:1186 Cluster Configuration --------------------- [ndbd(NDB)] 2 node(s) id=2 @198.51.100.30 (Version: 8.0.26-ndb-8.0.26, Nodegroup: 0, *) id=3 @198.51.100.40 (Version: 8.0.26-ndb-8.0.26, Nodegroup: 0) [ndb_mgmd(MGM)] 1 node(s) id=1 @198.51.100.10 (Version: 8.0.26-ndb-8.0.26) [mysqld(API)] 1 node(s) id=4 @198.51.100.20 (Version: 8.0.26-ndb-8.0.26) You can also verify that the SQL node is connected to the NDB Cluster in the  mysql  client ( mysql.exe ) using the  SHOW ENGINE NDB STATUS  statement. 3993
