== About ==
Eclipse Mosquitto™ is an open source (EPL/EDL licensed) message broker that implements the MQTT protocol versions 3.1 and 3.1.1. MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "Internet of Things" messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers like the Arduino.
This description is about how to install the mosquitto broker service on SME9/Centos6.
== Installation ==
=== Setting the Mosquitto MQTT YUM repositories ===
/sbin/e-smith/db yum_repositories set mosquitto repository \
Name 'Mosquitto MQTT CentOS-$releasever' \
BaseURL 'http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-$releasever/' \
EnableGroups no \
GPGCheck yes \
GPGKey 'http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-$releasever//repodata/repomd.xml.key' \
Visible no \
status disabled
signal-event yum-modify
=== Yum Installation ===
yum install mosquitto mosquitto-clients --enablerepo=mosquitto
=== Create a 'mosquitto' user ===
adduser mosquitto
=== Set SME Configuration ===
config set mosquitto service
config setprop mosquitto TCPPort 1883
config setprop mosquitto access public
config show mosquitto
signal-event remoteaccess-update
=== Enable As Service ===
chkconfig mosquitto --add
chkconfig mosquitto --level 2345 on
cd /etc/rc.d/rc7.d
ln -s ../init.d/mosquitto S50mosquitto
=== Setup Log Path ===
mkdir /var/log/mosquitto
=== Enable Write Access To Log ===
cd /var/log/mosquitto
chmod mosquitto:mosquitto .
=== Update Mosquitto Configuration ===
In /etc/mosquitto/mosquitto.conf
Add line:
user mosquitto
Add/change line:
log_dest file /var/log/mosquitto/mosquitto.log
=== Start Mosquitto Service ===
service mosquitto start
== Enable Port 1883 Forwarding ==
On your internet gateway router, enable TCP port 1883 to allow MQTT clients access the broker.
== Testing Access To The Broker ==
On a command line on your server use something like:
mosquitto_pub -d -t sensors/temperature -m 32 -q 1
If you get an output like below, your server is functional:
Client mosqpub/22329-franka sending CONNECT
Client mosqpub/22329-franka received CONNACK
Client mosqpub/22329-franka sending PUBLISH (d0, q1, r0, m1, 'sensors/temperature', ... (2 bytes))
Client mosqpub/22329-franka received PUBACK (Mid: 1)
Client mosqpub/22329-franka sending DISCONNECT
