Hello !
I ended up finding the problem. I don't know why, but I have tried to
replace all the IP addresses (192.168.0.19) by localhost then 127.0.0.1
then 0.0.0.0 and finally nothing. Just ":" followed by the port.
I don't know what is the difference for the moment, but when I don't put
any IP address, HAProxy now start at GNU/Linux boot.
So instead of having this :
bind 192.168.0.19:26000
mode tcp
default_backend all_java_srv
backend all_java_srv
balance roundrobin
mode tcp
server srv_1 192.168.0.19:26001
I have now :
bind :26000
mode tcp
default_backend all_java_srv
backend all_java_srv
balance roundrobin
mode tcp
server srv_1 :26001
I expect it may help some people to solve this problem when using only
one server.
Thanks for your help.

Hello !
I am testing HAProxy on my computer and my own "Internet Service
Provider" router (FreeBox).
My router is receiving TCP data on port 26000 and transmitting them to
local network
HAProxy, which is on my computer, is configured to listen data on port
26000 in the "Frontend" section.
Finally, the data should be transmitted to my Application using the
port 26001 thanks to the "Backend" section of HAProxy.
Here is a picture which can "help" you to understand.
At the boot, HAProxy say "Starting frontend srv_java: cannot bind
socket [192.168.0.19:26000]".
I think I have already solved a similar problem by starting the
Application using the port 26001 by creating a service
file(java-srv.service). I have a doubt with the using of
Requires/Wants but it seems to work.
It was an understandable problem.
But now, I don't see how to solve this new error.
Indeed, the port 26000 doesn't rely to an application to start, but
only to my router which is already running. So the port 26000 should
be always available.
In addition, when I just use the command "sudo service haproxy
restart", HAProxy works very well.
Maybe it's a simple problem, but I don't see solutions for the moment.
Have you any idea to solve it ?
If you need more details, doesn't hesitate to ask me.
Thanks a lot for your help,
Sincerely,
Axel DUMAS.
