Pourquoi et quand exécuter cette tâche

HAProxy provides load balancing and reverse proxy capabilities for both HTTP and TCP requests. The HAProxy checks remove backend servers that fail several health checks in a row, and transfer incoming traffic to backend servers as part of load balancing.

Procédure

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 enable
   stats show-legends
   stats refresh 5s
   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:
   sudo service haproxy restart
4. View the HAProxy metrics on your system by viewing the HAProxy metrics stats page, accessible from the following URL:
   http://<HAProxyServer>:8080/stats
