Deleting a REST API User for MaxScale with MaxCtrl

Overview

MaxScale has a REST API, which can be configured to require authentication. When it is first installed, it has a single default admin user (admin) and password (mariadb). However, this user can be deleted, and other users can be created.

MaxCtrl is a command-line utility that can perform administrative tasks using MaxScale's REST API. It can be used to delete a user for the REST API.

Deleting a User

1. Configure the REST API if the default configuration is not sufficient.

2. Use MaxCtrl to execute the destroy user command:

$ maxctrl --secure \
   --user=maxscale_rest_admin \
   --password=maxscale_rest_admin_password \
   --hosts=192.0.2.100:8443
   --tls-key=/certs/client-key.pem \
   --tls-cert=/certs/client-cert.pem \
   --tls-ca-cert=/certs/ca.pem \
   destroy user "admin"

Replace admin with the actual user.

MaxScale will refuse to delete the last remaining admin user.
