Haproxy fails to restart - haproxy

Question

We are facing an issue to start the haproxy we installed.
We are using ubuntu 16.04 and the version installed is:
HA-Proxy version 1.6.3 2015/12/25
Copyright 2000-2015 Willy Tarreau
The folder /run/haproxy is created
Everything is dowloaded correctly.
Its uninstalled, and then installed with the same errors, so we desperatly seek help.
This is the folder /etc/default/haproxy
# Defaults file for HAProxy
#
# This is sourced by both, the initscript and the systemd unit file, so do not
# treat it as a shell script fragment.
# Change the config file location if needed
#CONFIG="/etc/haproxy/haproxy.cfg"
ENABLED=1
# Add extra flags here, see haproxy(1) for a few options
#EXTRAOPTS="-de -m 16"
Here is /etc/haproxy/haproxy.cfg

Anyone who can help? :)

Answer 1

in your /etc/haproxy/haproxy.cfg file under the global section, there is this entry - stats socket /run/haproxy/admin.sock mode 660 level admin
check if admin.sock file is getting created. also check if there is the directory path existing for that file to be created.
