Introduction
Every VerneMQ node has to be configured. Depending on the installation method and chosen platform the configuration file vernemq.conf resides at different locations. If VerneMQ was installed through a Linux package the default location for the configuration file is /etc/vernemq/vernemq.conf.
A single setting is handled on one line.
Lines are structured
Key = ValueAny line starting with # is a comment, and will be ignored
You certainly want to try out VerneMQ right away. For that you could disable authentication like so:
Set
allow_anonymous = on
By default the vmq_acl authorization plugin is enabled and configured to allow publishing and subscribing to any topic, see here for more information.
Warning: Setting allow_anonymous=on completely disables authentication in the broker and plugin authentication hooks are never called! See more information about the authentication hooks here. Further, in a production system you should configure vmq_acl to be less permissive or configure some other plugin to handle authorization.
