Install Chkrootkit software on CentOS 7 with 3 extremely simple steps.
What is Chkrokit?
Chkrootkit is a popular security scanner that helps administrators look for signs when a system is infected with a rootkit. You can use Chkrootkit to find files and rules associated with rootkits, but you cannot be 100% sure that all rootkits will be found and removed.
You can install Chkrookit directly from the Repo repository, but in this article, AZDIGI will install it from the source to ensure that the installed version is the latest.
Step 1: SSH into your server
To upgrade the ProFTPD version on DirectAdmin, we first need to SSH or access your VPS/server with root privileges. If you don’t know how to SSH into your VPS/Server, you can refer to the following tutorial:
Step 2: Download and install Chkrookit
- Install C/C++ compilers and libraries
yum update yum install wget gcc-c++ glibc-static
- Download latest chkrootkit
wget -c ftp://ftp.pangeia.com.br/pub/seg/pac/chkrootkit.tar.gz
- Download the md5 package
wget ftp://ftp.pangeia.com.br/pub/seg/pac/chkrootkit.md5 md5sum -c chkrootkit.md5 chkrootkit.tar.gz: OK
- Decompression and install
tar -zxvf chkrootkit.tar.gz mkdir /usr/local/chkrootkit mv chkrootkit*/* /usr/local/chkrootkit cd /usr/local/chkrootkit make sense
- Next, you can run chkrootkit to scan the server with the command below:
Step 3: Install automatic rootkit scanning on the system and report scanned information
You can add a cron entry to run chkrootkit automatically and send scan reports to your mailing address. Please create and add the following to/etc/cron.daily/chkrootkit-scan.sh.
vi /etc/cron.daily/chkrootkit-scan.sh chmod 700 /etc/cron.daily/chkrootkit-scan.sh
And add the following content to the newly created file:
#!/bin/sh ( /usr/local/chkrootkit/chkrootkit ) | /bin/mail -s 'CHROOTKIT Daily Run ServerName' firstname.lastname@example.org
So in this article, AZDIGI showed you how to install Chkrootkit on a complete CentOS 7 server. With Chkrootkit, you will have more options and security options for your data and your server. Hope this article will help you, wish you success!
