The NDB Cluster Auto-Installer (No longer supported) In either case, once  ndb_setup.py  is invoked, the Auto-Installer’s  Welcome  screen should open in the system’s default web browser. If not, you should be able to open the page  http://localhost:8081/ welcome.html  or  https://localhost:8081/welcome.html  manually in the browser. In some cases, you may wish to use non-default settings for the installer, such as specifying HTTPS for connections, or a different port for the Auto-Installer’s included web server to run on, in which case you must invoke  ndb_setup.py  with one or more startup options with values overriding the necessary defaults. The same startup options can be used on Windows systems with the  setup.bat  file supplied for such platforms in the NDB Cluster software distribution. This can be done using the command line, but if you want or need to start the installer from a desktop or file browser while employing one or more of these options, it is also possible to create a script or batch file containing the proper invocation, then to double- click its file icon in the file browser to start the installer. (On Linux systems, you might also need to make the script file executable first.) If you plan to use the Auto-Installer from a remote host, you should start using the  -S  option. For information about this and other advanced startup options for the NDB Cluster Auto-Installer, see Section 23.4.26, “ndb_setup.py — Start browser-based Auto-Installer for NDB Cluster (DEPRECATED)” . The  Welcome  screen is loaded in the default browser when  ndb_setup.py  is invoked. The first time the Auto-Installer is run (or if for some other reason there are no existing configurations), this screen appears as shown here: In this case, the only choice of cluster listed is for configuration of a new cluster, and both the  View Cfg and  Continue  buttons are inactive. To create a new configuration, enter and confirm a passphrase in the text boxes provided. When this has been done, you can click  Continue  to proceed to the  Define Cluster  screen where you can assign a name to the new cluster. 4011 NDB Cluster Auto-Installer Welcome Screen Figure 23.8 The NDB Cluster Auto-Installer Welcome screen, first run
