1 Login to your server as root

2. cd /usr/local/src

3 Download RKHunter and extract the archive

wget http://downloads.rootkit.nl/rkhunter-1.1.4.tar.gz

Some time above URL is working fine due to that you can also use following URL to download the tar file.

http://sourceforge.net/projects/rkhunter/files/rkhunter/1.3.4/rkhunter-1.3.4.tar.gz/download?use_mirror=autoselect

tar -xzvf rkhunter-1.1.4.tar.gz

4. Install RKHunter

cd rkhunter

./installer.sh

Or

./installer.sh –layout default –install

You can also set the cron to receive the RKHunter result.

vi /etc/cron.daily/rkhunter.sh
#!/bin/bash
(/usr/local/bin/rkhunter –update && /usr/local/bin/rkhunter -c –nocolors –skip-keypress –summary 2>&1 | mail -s “RKhunter Scan Details” username@yourdomain.com)

chmod a+x /etc/cron.daily/rkhunter.sh

As RKHunter now updated its version therefore it could be possible that above steps or URL won’t work therefore please refer to the following new steps to install RKHunter

root@server [~]# cd /usr/local/src

root@server[~]#wget http://downloads.sourceforge.net/project/rkhunter/rkhunter/1.3.8/rkhunter-1.3.8.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Frkhunter%2Ffiles%2Frkhunter%2F1.3.8%2F&ts=1323513745&use_mirror=space

root@server [~]#tar -xvf rkhunter-1.3.8.tar.gz
