How to write log all to Harddisk instead Ram Disk?

[pfsense-client]

Hi,
I install pfsense to harddisk and want to write log file to local disk instead ram disk (Don't use syslog server).

You can't.  pfSense isn't designed to work that way.  Use a remote syslog server.

You "could" set up a syslog server onthe pfSense itself.
A quick google gives this: http://www.tutorialized.com/view/tutorial/Setup-a-Syslog-Server/36094

However this is NOT SUPPORTED and you are on your own if you have problems.
Also it might introduce security breaches.
