Hello, I am successfully running HAProxy 1.4.24 on CentOS 6. I am
upgrading my environment to CentOS 7 and HA-Proxy 1.5. I have
configured the replacement load balancer with the same configuration.
After installing and enabling the service to start on boot, I attempt
to reboot and haproxy does not run on the new install. Running a
systemctl status -l haproxy command gives me the following output:

If I try running haproxy using the following command haproxy starts
successfully, balances traffic, and supplies the stats page correctly:
[root@haproxy2 ~]# haproxy -f /etc/haproxy/haproxy.cfg
And I can see the process running:
[root@haproxy2 ~]# pgrep haproxy
2543
-----------------------------------------------------------------------------
The following is the section of the config file that sets up the stats
page:
userlist UsersFor_HAProxyStatistics
group admin users haproxy
user haproxy insecure-password HA@VmView5
user stats insecure-password letmein
listen stats *:1936
mode http
stats enable
#stats scope http
#stats scope www
#stats scope static
#stats scope static_httpclose
#stats realm Haproxy\ Statistics

#stats auth haproxy:HA@VmView5

acl AuthOkay_Admin http_auth_group(UsersFor_HAProxyStatistics)

I am not strong in Linux, but it appears that running it as root
works, but running it on startup it does not. Any ideas would be
helpful. Thank you!

Hi
If you are able to run this as root, then the problem is not with
haproxy, but rather the start procedure and that is where you will need
to start looking.
Probably better in a Centos7 group on centos.org.
