Re: Need help to reolsve haproxy issue
Sorry for the late reply, I was on unplanned leave. What I observed in my investigation, when I commented below line it's working as expected. Means even after reboot the machine the haproxy service get started automatically. #stats socket /etc/haproxy/haproxysock level admin I'm not sure what is the significance of this line. Can we proceed with this in our configuration or will it cause any issues further? NOTE : I couldn't find haproxy-wrapper under below location /usr/sbin> ls -ltr *haproxy* -rwxr-xr-x 1 root root 35152 Sep 3 2014 haproxy-halog -rwxr-xr-x 1 root root 788672 Sep 3 2014 haproxy lrwxrwxrwx 1 root root 19 Jan 9 01:47 rchaproxy -> /etc/init.d/haproxy Thanks in advance.

Re: Need help to reolsve haproxy issue
I've not personally had any issues with systemd which I know doesn't mean there isn't any... However, on closer inspection, it gets started through a wrapper "haproxy-systemd-wrapper" for me : [Unit] Description=HAProxy Load Balancer After=network.target [Service] ExecStartPre=/usr/local/sbin/haproxy -f /etc/haproxy/haproxy.cfg -c -q ExecStart=/usr/local/sbin/haproxy-systemd-wrapper -f /etc/haproxy/haproxy.cfg -$ ExecReload=/bin/kill -USR2 $MAINPID KillMode=mixed Restart=always [Install] WantedBy=multi-user.target So definitely check if you are using that wrapper or not if systemd is being used. Otherwise, my feeling is that for whatever reason you cannot access the socket previously created due to permissions... I mean I can get the same error trying to start HAproxy as an unprivileged user who cannot write to the file/directory.

Re: Need help to reolsve haproxy issue
Might be a systemd dependency issue, where the socket is not created before the process is started.

Re: Need help to reolsve haproxy issue
Hi Praveen, Am I right in assuming it's a socket for the stats page? Also what user is starting HAproxy because maybe it doesn't have permissions to create the socket? We might need your whole config or at least the GLOBAL section...

Re: Need help to reolsve haproxy issue
There are some very knowledgeable people on this list so I'm sure someone can help, however, what might the problem actually be?

Re: Need help to reolsve haproxy issue
Some content was missing. Adding again. When we reboot our machine (Where haproxy installed) teh haproxy going to be down and it's not starting after machine boot. When we force to start haproxy service getting below error.
