[syslog-ng] CentOS 7.2 // Syslog-ng (syslog-ng_3.6.4)

Hello guys, Happy new year!! Hope you are doing great. I've installed (compiled ) syslog-ng on CentOS Linux 7 (Core) but after I got through the install which is all good, I cant get it to start, all it says is : systemctl status syslog-ng ● syslog-ng.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) [vch@slc ~]$ sudo systemctl enable syslog-ng Failed to execute operation: No such file or directory [vch@slc ~]$ sudo systemctl start syslog-ng Failed to start syslog-ng.service: Unit syslog-ng.service failed to load: No such file or directory. Rsyslog is not running, I can't think of any, I am I missing some simple ?????? Any help is appreciated. -- Thanks, Vijay Amrut.
