cannot bind socket - Need help with config file

[Imam Toufique]

Hi,

I need some help figuring out why my config below is failing to start the
haproxy daemon.  I am totally new to this.

Below is my confg:


global
#   local2.* /var/log/haproxy.log
    #
   log         127.0.0.1 local2
   #local2.* /var/log/haproxy.log
   chroot /var/log/haproxy
   #stats timeout 30s
   user haproxy
   group haproxy
   daemon

defaults
   log global
   mode tcp
   option tcplog
   option dontlognull
   timeout connect 5000
   timeout client 50000
   timeout server 50000


frontend sftp-server
   bind *:22
   default_backend sftp_server
   timeout client 1h


listen stats 10.0.15.23:22
bind :22
mode tcp
maxconn 2000
option redis-check
retries 3
option redispatch
balance roundrobin

use_backend sftp_server
backend sftp_server
balance roundrobin
server web 10.0.15.21:22 check weight 2
server nagios 10.0.15.15:22 check weight 2

When I run a config check, i get this:

[root@file haproxy]# haproxy -f ./haproxy.cfg -c
Configuration file is valid

when I try to start haproxy, I get the following error:

[root@file haproxy]# haproxy -f ./haproxy.cfg -d
Available polling systems :
      epoll : pref=300,  test result OK
       poll : pref=200,  test result OK
     select : pref=150,  test result FAILED
Total: 3 (2 usable), will use epoll.
Using epoll() as the polling mechanism.
[ALERT] 007/081940 (1416) : Starting frontend sftp-server: cannot bind
socket [0.0.0.0:22]
[ALERT] 007/081940 (1416) : Starting proxy stats: cannot bind socket [
10.0.15.23:22]
[ALERT] 007/081940 (1416) : Starting proxy stats: cannot bind socket [
0.0.0.0:22]

In the config above, I am trying to setup 2 SFTP servers load-balanced with
haproxy.  I would like to use port 22 , for sftp.

Please help, I need to get this going.

thanks.
