Individual log files using syslog
 

I am running Centos/Apache with PHP 5.5.14, and am using syslog to write to a log file as follows:

syslog(LOG_INFO,'Some message');

The logs are being written to /var/log/messages and look like "Aug 10 15:48:16 devserver httpd: Some message", however, the log file is also cluttered with a bunch of logs that look like "Aug 10 15:48:21 devserver kernel: usb 1-1.2: USB disconnect, device number 83".

How do make PHP send logs to its own dedicated log file?

Note that I don't think this is a PHP question, but a syslog question. I also don't wish to create my own PHP version log writer, but use syslog.

Thanks

I've been reading a bit about syslog. Evidently, the service can be started/stopped using /etc/init.d/syslog, but my server doesn't seem to have that service. Furthermore, it could be configured using /etc/syslog.conf, but I also don't have that file. It appears that Centos does it differently. Looks like I should use rsyslog, right?

The logs I care about all include httpd. For instance:
Would I be able to just put those logs in a different log file?

Okay, maybe I have a solution. Edit rsyslog.conf and add the following.
Note that I did NOT remove local0 from also going to /var/log/messages. For instance, I did not add the following:
It is bad practice to allow messages to go to two logs?

I now log this way:
I guess I am good, but if anything sticks out as being wrong, please advise.
