2.8.2 to 2.9.6 HAPROXY Wont start after update

Help: I am currently running 2.8.2 and upgraded and built 2.9.6. HAPROXY runs as expected with no problems on 2.8.2 but fails when starting 2.9.x. I am a little lost as to why or what would cause the application not to start the service.

Starting on 2.9.6

Ran it manually and see if an error shows up:

systemctl stop haproxy
killall haproxy
/usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg
killall haproxy

That is interesting. Running it manually seems to run fine but fails if I run it through systemctl.

[root@ha01 haproxy]# ps -ef |grep haproxy

Job for haproxy.service failed because the control process exited with error code.

Did you look at the output of those commands?

Here is one of the outputs.

ha01 ~]# systemctl status haproxy.service

try this command to check syntax

haproxy -c -f /etc/haproxy/haproxy.cfg

let me know the output

This tells me that you need to run this command

systemctl enable haproxy
