Re: Need help to reolsve haproxy issue

[Praveen Koppula]

 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

[Aaron West]

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.

Might be a systemd dependency issue, where the socket is not created before
the process is started.

Re: Need help to reolsve haproxy issue

[Aaron West]

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...

[Aaron West]

There are some very knowledgeable people on this list so I'm sure someone
can help, however, what might the problem actually be?

Some content was missing. Adding again.

be down and it's not starting after machine boot.
When we force to start haproxy service getting below error.
