Cassandana is an open source MQTT message broker which is entirely written in Java. This project began its life as a fork of Moquette , and later underwent some cleanup, optimization and adding extra features. Now it’s ready to work as an enterprise message broker.
•MQTT compliant broker.
•Supports QoS 0, QoS 1 and QoS 2
•TLS (SSL) Encryption
•PostgreSQL, MySQL and MongoDB Authentication and Authorization
•Supports Cassandra for Authentication, Authorization and Message Archiving
•Supports HTTP REST API for Authentication and Authorization
Cassandana is cross-platform, which could be deployed on Linux, FreeBSD, Mac and Windows.
Download source code from GitHub by following command:
the go to the downloaded directory
cassandana uses maven to build:
jar file will be created in a new directory is called target.
After building the jar file from source code or grabbing it from release, follow the instruction below:
in case of building from source code:
if you downloaded jar file from release:
copy YAML file (cassandana's configuration file) to /opt/cassandana/
To make Cassandana runs at boot time in Debian use initd script from scripts directory which is provided in source code
tested in debian jessie and stretch To start|stop|restart use the following command
The configuration file is written in YAML. threads it's the number of process. It's highly recommended to equal the number of CPU cores. Value 0 means all available CPU cores (default value 0). host IP Address which server should listen to it (default value is 0.0.0.0). port Port number which server should listen to it (default value is default MQTT port 1883).
If you would like to use web-socket enabled it from this section otherwise set enabled to no.
This section determines if SSL should be enabled.
If you would like to enable secure web-socket use the following configuration:
When you enabled SSL or WSS you should provide certification's information:
allow_anonymous: yes no to accept only client connections with credentials and yes to accept client connection without credentials, validating only the one that provides.
Cassandana uses several methods to authenticate and authorize the users:
•Database (MySQL, PostgreSQL, MongoDB, Cassandra)
•Permit All
•Deny All
•HTTP REST API
•Redis (In memory key-value database)
HTTP-based authentication can be performed as below:
HTTP-based authorization can be performed as below:
if asks for publishing acl should be set to pub otherwise in case of subscription set it to sub
Note: There is a sample HTTP server written in NodeJS in example directory.
Authentication can be performed by Redis as a backend to store username and password. Password should be hashed with sha256. To configuring Redis connection use the below parameters:
