Subject Re: Start service of Firebird 2.5 in Centos 7
Author
Hello how did you installed it ? 
On Centos7 you need epel repository 


https://fedoraproject.org/wiki/EPEL

 


yum –enablerepo=epel install firebird-superclassic
and since EPEL 7 use Systemd, you can use Systemd to enable the service

and stop or start it
read the README provided :
http://pkgs.fedoraproject.org/cgit/firebird.git/tree/README.Fedora?h=epel7

systemctl start firebird-superclassic.service

If you want to have firebird started at each boot, as root :
  for SuperClassic :  systemctl enable firebird-superclassic.service
