Procedure

  1. Access the HAProxy configuration file, located at: /etc/haproxy/haproxy.cfg.
  2. Add the following to the bottom of the file: 
    listen frontend *:8080       #Haproxy 
Monitoring run on port 8080
mode http
option forwardfor
option httpclose

stats uri /stats        #URL for HAProxy monitoring
stats realm Haproxy\Statistics.   #Title for pop up window
stats auth admin:admin     #User and Password for login to the monitoring dashboard
stats admin if TRUE
default_backend backend       #This is optional for monitoring backend
  3. Run the following command to restart the HAProxy:
