Installing NDB Cluster on Windows command line, it is usually more convenient to place them in an option file. To do this, create a new text file in Notepad or another text editor. Enter the following configuration information into this file: You can add other options used by this MySQL Server if desired (see Section 2.3.4.2, “Creating an Option File” ), but the file must contain the options shown, at a minimum. Save this file as  C:\mysql\my.ini . This completes the installation and setup for the SQL node. Data nodes.   An NDB Cluster data node on a Windows host requires only a single executable, one of either  ndbd.exe  or  ndbmtd.exe . For this example, we assume that you are using  ndbd.exe , but the same instructions apply when using  ndbmtd.exe . On each computer where you wish to run a data node (the computers having the IP addresses 198.51.100.30 and 198.51.100.40), create the directories  C: \mysql ,  C:\mysql\bin , and  C:\mysql\cluster-data ; then, on the computer where you downloaded and extracted the  no-install  archive, locate  ndbd.exe  in the  C:\mysql\bin  directory. Copy this file to the  C:\mysql\bin  directory on each of the two data node hosts. To function as part of an NDB Cluster, each data node must be given the address or hostname of the management server. You can supply this information on the command line using the  --ndb- connectstring  or  -c  option when starting each data node process. However, it is usually preferable to put this information in an option file. To do this, create a new text file in Notepad or another text editor and enter the following text: Save this file as  C:\mysql\my.ini  on the data node host. Create another text file containing the same information and save it on as  C:mysql\my.ini  on the other data node host, or copy the my.ini file from the first data node host to the second one, making sure to place the copy in the second data node’s  C: \mysql  directory. Both data node hosts are now ready to be used in the NDB Cluster, which leaves only the management node to be installed and configured. Management node.   The only executable program required on a computer used for hosting an NDB Cluster management node is the management server program  ndb_mgmd.exe . However, in order to administer the NDB Cluster once it has been started, you should also install the NDB Cluster management client program  ndb_mgm.exe  on the same machine as the management server. Locate these two programs on the machine where you downloaded and extracted the  no-install  archive; this should be the directory  C:\mysql\bin  on the SQL node host. Create the directory  C:\mysql\bin  on the computer having the IP address 198.51.100.10, then copy both programs to this directory. You should now create two configuration files for use by  ndb_mgmd.exe : To create this file, start a new text file in Notepad or another text editor, and enter the following information: Save this file as the text file  C:\mysql\bin\my.ini . 3989 1. A local configuration file to supply configuration data specific to the management node itself. Typically, this file needs only to supply the location of the NDB Cluster global configuration file (see item 2).
