RKHunter Configuration Guide

Published January 23, 2010 by Siva

Rkhunter is a very useful tool that is used to check for trojans, rootkits, and other security problems. This tutorial will touch on installing and setting up a daily report for rkhunter.



tar -zxvf rkhunter-1.2.7.tar.gz
cd rkhunter-1.2.7
./ –layout /usr/local/rkhunter –install

Updating rkhunter

gets the latest database updates from their central server and matches your OS better to prevent false positives

rkhunter –update

Now you can run a test scan with the following command:

/usr/local/bin/rkhunter -c

How to setup a daily scan report?

vim /etc/cron.daily/

add the following replacing your email address:

/usr/local/bin/rkhunter –cronjob –rwo –nocolors | mail -s “Rkhunter daily run on `uname -n`”
exit 0

chmod +x /etc/cron.daily/


Dump just the table structure to a file in MySQL

We will use the mysqldump utility the same as if we were backing upo the entire database


mysqldump -d -h localhost -u root -p databasename > dumpfile.sql

The only option that is different than creating an entire backup is the -d switch, which tells mysqldump not to output the data.


mysqldump -d -h localhost -u root -p sampledatabase  > dumpfile.sql
