If you are building a system that serves both HTTP and MQTT, I sure that you have to use HAProxy. So in this post, I will share you the way to setup HAProxy to serve Nginx and MQTT Broker.
Your haproxy.cfg file should contain the source code below:
Haproxy MQTT Configuration
|
1 2 3 4 5 6 |
listen mqtt bind *:1883 mode tcp option tcplog balance leastconn server broker_1 broker:1883 check |
Note: broker is MQTT Broker’s hostname
Haproxy Nginx
|
1 2 3 4 5 6 |
listen http bind *:80 mode tcp option tcplog balance leastconn server nginx_1 nginx:80 check |
For monitoring Haproxy, You can add Haproxy Stats Configuration
|
1 2 3 4 5 6 |
listen stats :1936 mode http stats enable stats hide-version stats realm Haproxy\ Statistics stats uri / |
Final Result haproxy.cfg
