MySQL Cluster Auto-lnstaller Overview

The MySQL Cluster Auto-lnstaller is madę 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 (see Section 17.2.1.1. “MySQL Cluster Auto-lnstaller Requirements”). The

back end is a server process (ndb_setup. py) that runs on the local machinę 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 MySQL Cluster software programs on any host

where the back end user has granted access. If the MySQL Cluster software is on a different host, the

back end relies on SSH for access, using the Paramiko library for executing commands remotely (see

Section 17.2.1.1, “MySQL Cluster Auto-lnstaller Requirements").

The remainder of this section is concerned primarily with the Web Client. For morę information about

using the command-line tool, see Section 17.4.22, “ndb_setup. py — Start browser-based Auto-lnstaller for MySQL Cluster".
