[nsd-users] NSD failed to start via service on CentOS 7

Resolved.
Sorry for incorrect question.

SELinux prevents NSD from starting.

Тема: [nsd-users] NSD failed to start via service on CentOS 7

Hi,
I've installed nsd from packages via epel-repository.

When try to start service listening on port 65053 with:
[root at ns1 nsd]# service nsd status
Is does not work:

# cat /var/log/messages | grep nsd
Sep  6 11:28:35 ns1 nsd[1370]: nsd starting (NSD 4.1.24)
Sep  6 11:28:35 ns1 nsd[1370]: can't bind udp socket: Permission denied
Sep  6 11:28:35 ns1 nsd: [2019-09-06 11:28:35.314] nsd[1370]: notice: nsd starting (NSD 4.1.24)
Sep  6 11:28:35 ns1 nsd: [2019-09-06 11:28:35.314] nsd[1370]: error: can't bind udp socket: Permission denied
Sep  6 11:28:35 ns1 nsd: [2019-09-06 11:28:35.314] nsd[1370]: error: server initialization failed, nsd could not be started
Sep  6 11:28:35 ns1 nsd[1370]: server initialization failed, nsd could not be started
Sep  6 11:28:35 ns1 systemd: nsd.service: main process exited, code=exited, status=1/FAILURE
Sep  6 11:28:35 ns1 systemd: Unit nsd.service entered failed state.
Sep  6 11:28:35 ns1 systemd: nsd.service failed.

Looks like something wrong with user rights because nsd-control works:
[root at ns1 nsd]# nsd-control start
[2019-09-06 11:39:38.295] nsd[1414]: notice: nsd starting (NSD 4.1.24)
[root at ns1 nsd]# ps aux | grep nsd
nsd       1415  0.9 16.9 168776 84872 ?        Ss   11:39   0:00 nsd -c /etc/nsd/nsd.conf
nsd       1416  0.3  6.5 100304 32880 ?        S    11:39   0:00 nsd -c /etc/nsd/nsd.conf
nsd       1417  0.0  0.2 100436  1136 ?        S    11:39   0:00 nsd -c /etc/nsd/nsd.conf

This is only centos package issue or I should tweak nsd.conf somehow?

Thanks in advance.
