This has to be something very basic.
Have you tried checking if another syslog server is running? 
ps -aef |grep syslog

Assuming this shows nothing, try a very simple syslog-ng config file and a manual start on the command line. 

Make sure you check all the things in your configuration that your copy should open beforehand. 

This should narrow down the problem I hope :-)

And i have the similar errors when ever i try to install on new CentOS

The procedure im doing is: Fresh installation of CentOS
yum update
yum install httpd php vim wget
then install mongodb ( add repo )
then install syslog-ng ( add repo )

I'm using: CentOS Linux release 7.2.1511 (Core)
And im having the following repos:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest


Any idea ?

Hi,

You should add the repository using the file:
https://copr.fedorainfracloud.org/coprs/czanik/syslog-ng37/repo/epel-7/czanik-syslog-ng37-epel-7.repo
to yum and not just download individual packages. You can use then
"yum install syslog-ng" which will also download all necessary
dependencies.
