•NDB 8.0.22 adds support for IPv6 addressing for management nodes and data nodes in the config.ini  file. To begin using IPv6 addresses as part of an upgrade, perform the following steps: 

1. Perform an upgrade of the cluster to version 8.0.22 or a later version of the NDB Cluster software in the usual manner. 

2. Change the addresses used in the config.ini  file to IPv6 addresses. 

3. Perform a system restart of the cluster. 

•Due to changes in the internal mysql.ndb_schema  table, if you upgrade to an NDB 8.0 release prior to 8.0.24, then you are advised to use ndb_schema_dist_upgrade_allowed = 0  to avoid unexpected outages (Bug #30876990, Bug #31016905). 

## 23.2.8 The NDB Cluster Auto-Installer (No longer supported) 

Note 

This feature has been removed from NDB Cluster, and is no longer supported. See Section 23.1.4, “What is New in NDB Cluster” , for more information. 

This section describes the web-based graphical configuration installer included as part of the NDB Cluster distribution. Topics discussed include an overview of the installer and its parts, software and other requirements for running the installer, navigating the GUI, and using the installer to set up and start or stop an NDB Cluster on one or more host computers. 

The NDB Cluster Auto-Installer is made up of two components. The front end is a GUI client implemented as a Web page that loads and runs in a standard Web browser such as Firefox or Microsoft Internet Explorer. The back end is a server process ( ndb_setup.py ) that runs on the local machine or on another host to which you have access. 

These two components (client and server) communicate with each other using standard HTTP requests and responses. The back end can manage NDB Cluster software programs on any host where the back end user has granted access. If the NDB Cluster software is on a different host, the back end relies on SSH for access. 

## 23.2.8.1 NDB Cluster Auto-Installer Requirements 

This section provides information on supported operating platforms and software, required software, and other prerequisites for running the NDB Cluster Auto-Installer. 

Supported platforms. The NDB Cluster Auto-Installer is available with NDB 8.0 distributions for recent versions of Linux, Windows, Solaris, and macOS. For more detailed information about platform support for NDB Cluster and the NDB Cluster Auto-Installer, see https://www.mysql.com/support/supportedplatforms/ cluster.html. 

Supported web browsers. The web-based installer is supported with recent versions of Firefox and Microsoft Internet Explorer. It should also work with recent versions of Opera, Safari, and Chrome, although we have not thoroughly tested for compability with these browsers. 

Required software—setup host. The following software must be installed on the host where the Auto- Installer is run: 

• Python 2.6 or higher. The Auto-Installer requires the Python interpreter and standard libraries. If these are not already installed on the system, you may be able to add them using the system’s package manager. Otherwise, you can download them from http://python.org/download/.
