Deleting a REST API User for MaxScale with MaxCtrl

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.
