MariaDB MaxScale MaxGUI Guide

Introduction

MaxGUI is a browser-based interface for MaxScale REST-API and query execution.

Enabling MaxGUI

To enable MaxGUI in a testing mode, add admin_host=0.0.0.0 and admin_secure_gui=false under the [maxscale] section of the MaxScale configuration file. Once enabled, MaxGUI will be available on port 8989: http://127.0.0.1:8989/

Securing the GUI

To make MaxGUI secure, set admin_secure_gui=true and configure both the admin_ssl_key and admin_ssl_cert parameters.

See Configuration Guide and Configuration and Hardening for instructions on how to harden your MaxScale installation for production use.

Authentication

MaxGUI uses the same credentials as maxctrl. The default username is admin with mariadb as the password.

Internally, MaxGUI uses JSON Web Tokens as the authentication method for persisting the user's session. If the Remember me checkbox is ticked, the session will persist for 24 hours. Otherwise, the session will expire as soon as MaxGUI is closed.

To log out, simply click the username section in the top right corner of the page header to access the logout menu.
