Are you installing from source, or from a binary package? If the latter,
I'd suggest taking a look at our 3rd party binaries page:
 https://syslog-ng.com/3rd-party-binaries

Although, I'm not sure if there are any for CentOS6... The latest I can
find is syslog-ng 3.13:
 https://syslog-ng.com/blog/latest-syslog-ng-available-rhel-6-centos-6/

This suggests that you may need to compile from source if you want to
have the latest version. If you need help with that, we can certainly
help, but will need some more details, such as the exact problems you
are running into.

Anyway, installing it on the client and server side should be the same.
The difference would be in configuration.

    vinod> Query:-
    vinod> 1.Can we send  these logs on syslog-ng real time?

By all intents and purposes, yes. A few things (such as network) may
introduce slight delays, but otherwise yes.

    vinod> 2. Will log format be same as on client ?

That depends entirely on how you configure your clients and the central
server. It is possible to send logs over as-is, without any parsing at
all, and make them appear the same on the server too.
