installing mosquitto server and configuring

This tutorial explains basic steps of installing mosquitto server on openwrt platform. Mosquitto exists in openwrt barrier breaker repository but I decided to crosscompile it. At host computer in openwrt directory call :

uros-petrevski-2:bin uros$ ./scripts/feeds install mosquitto-nossl

This will install version that don’t support ssl layer because we don’t need it. We need server that is fast. Run make menuconfig and under Network select mosquitto nossl as M package.

uros-petrevski-2:bin uros$ make J=4

Then copy mosquitto package to weio. Mosquitto don’t have any dependencies.

uros-petrevski-2:packages uros$ scp /Volumes/openwrt/carambola/bin/ramips/packages/mosquitto-nossl_1.0.3-1_ramips.ipk [email protected]:/tmp

Now it’s time to install mosquitto

root@Weio:/tmp# opkg install mosquitto-nossl_1.0.3-1_ramips.ipk -d root

If you run mosquitto now it will break :

root@Weio:/tmp# mosquitto

11145: Error: Invalid user 'mosquitto'.

The reason is simple, user is not configured. As user is root we have to declare root user un mosquitto configuration. So edit /etc/mosquitto/mosquitto.conf file and add at user section

user root

If you want to run manually mosquitto (you can see what is happening with clients on the console) you have to do :

root@Weio:/# mosquitto -c /etc/mosquitto/mosquitto.conf

Parameter -c specify path to conf file. However if you want to run automaticaly on startup mosquitto server do following

root@Weio:/# /etc/init.d/mosquitto enable

Once system rebooted you can see mosquitto server running by :

root@Weio:/# ps | grep mosquitto

2570 root       932 S    /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf

2574 root      1488 S    grep mosquitto
