View Full Version : [SOLVED] HAProxy 1.6 Ubuntu 16.04 fails to start with 1.5 config file

January 5th, 2016, 12:31 AM
I'm testing Ubuntu 16.04

Seems that upgrading to 1.6.2 and also 1.6.3 of HAproxy, I cannot start the service with a custom config file that is working with v 1.5.x

Also it seems that the failure doesn't indicate any line number where the config may be failing. This is unusual given the previous experience with the HAproxy service startup script of 1.5.

It appears that the line for
frontend www bind is the cause. I believe this would be a bug :/

Found the cause, sticky sessions are no longer supported:
[ALERT] 004/103442 (15031) : parsing [/etc/haproxy/haproxy.cfg:80] : 'appsession' is not supported anymore, please check the documentation.
