HAproxy Disable Backend | How-to Guide

Did you know that the option to enable or disable backend servers isn’t available by default when using HAProxy?

However, we can set it up ourselves.

Here’s a guide by our experts to help us out with enabling & disabling the backend:

1. To begin with, install socat on Linux machine as seen below:

   sudo apt install socat
2. Next, open the HAProxy configuration file and add the following lines in the `global` section to enable the stats socket:

   global
stats socket /var/run/haproxy.sock mode 600 level admin
stats timeout 2m

3. Then, save the configuration file and restart the HAProxy service.

   sudo systemctl restart haproxy.service
4. Now, we can easily enable or disable your backend servers with these commands:
   • To enable a server:

     echo "enable server <backend_name>/<server_name>" | socat stdio /var/run/haproxy.sock

   • To disable a server:

     echo "disable server <backend_name>/<server_name>" | socat stdio /var/run/haproxy.sock

5. Now, we can check if a server is enabled or disabled by visiting the HAProxy stats page.

That’s it! We can now easily control our HAProxy backend servers without restarting the HAProxy server.
