This is a message broker that supports version 5.0, 3.1.1, and 3.1 of the MQTT protocol. MQTT provides a method of carrying out messaging using a publish/subscribe model. It is lightweight, both in terms of bandwidth usage and ease of implementation. This makes it particularly useful at the edge of the network where a sensor or other simple device may be implemented using an arduino for example.
By default mosquitto will be installed as a system service, using the default configuration at /snap/mosquitto/current/default_config.conf. If this does not meet your needs, create the file /var/snap/mosquitto/common/mosquitto.conf and this will be used instead. Note that only files inside /var/snap/mosquitto/common can be read by mosquitto, you cannot put other configuration files in /etc/mosquitto.
In addition to the latest channel, there are also the 1.5 and 1.6 channels which you can use to track those versions.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 42.3, Leap 15 and Tumbleweed.
You need first add the snappy repository from the terminal. Leap 15 users, for example, can do this with the following command:
Swap out openSUSE_Leap_15.0 for either openSUSE_Leap_42.3 or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
Finally, upgrade the package cache to include the new snappy repository:
Snap can now be installed with the following:
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
