I require to log syslogs into a mysql database. I used syslog-ng (downloaded the rpm for syslog-ng - ver 1.6 and libol from rpmseek.com and installed it) and used the information available in the site

http://www.vermeer.org/display_doc.php?doc_id=1 for this purpose. As given in this website

(1) First I made the pipe file using the following command

# mkfifo /tmp/mysql.pipe

(2) Then I used the following command to log into mysql (first tried with local logging)

# mysql -u root --password=passwd syslog < /tmp/mysql.pipe

This command gets stuck

But when syslog-ng is stopped and started it logs and the contenets in /tmp/mysql.pipe gets loaded into the database table. The following commands were used to stop and start syslog-ng

/etc/init.d/syslog-ng stop # Stop syslog-ng
/etc/ini.d/syslog-ng start # Start syslog-ng

(3) The site states about an initialization script like this one which needs to be started at start up.

The script given is provided below.

#!/bin/bash

if [ -e /tmp/mysql.pipe ]; then
while [ -e /tmp/mysql.pipe ]
do
mysql -u theuserid --password=thepassword syslogdb < /tmp/mysql.pipe
done
else
mkfifo /tmp/mysql.pipe
fi

Where should I put this script and how to start it up at initialization?

Could you explain the working pricipal of this script?
