Creating a REST API User for MaxScale with MaxCtrl

Overview

MaxScale has a REST API, which can be configured to require authentication. When 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 create a user for the REST API.

User Types

There are two types of users:

User Type	Description
User Type	Description
Basic	The user has read-only access
Admin	The user can change global MaxScale parameters and reconfigure modules.

Creating a Basic User

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

2. Use MaxCtrl to execute the create user command:

$ maxctrl --secure \
   --user=admin \
   --password=mariadb \
   --hosts=192.0.2.100:8443
   --tls-key=/certs/client-key.pem \
   --tls-cert=/certs/client-cert.pem \
   --tls-ca-cert=/certs/ca.pem \
   create user "maxscale_rest" "maxscale_rest_password"

Replace maxscale_rest and maxscale_rest_password with the desired user and password.

Creating an Admin User

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

2. Use MaxCtrl to execute the create user command with the --type=admin option:

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

Replace maxscale_rest_admin and maxscale_rest_admin_password with the desired user and password.
