In this tutorial we will show you how to install and configuration of ClamAV on your CentOS 6 server. For those of you who didn’t know, [ClamAV][] is an open source (GPL) antivirus engine designed for detecting viruses, malware and other malicious threats on Linux. It’s easy to use and best for Linux based Web & Mail server. In this article, I will show you through the step by step installation of ClamAV on CentOS 6.x from source.

## Install ClamAV on CentOS 6 ##

Step 1. First add yum repository your system.

The [EPEL repo][] is enabled by simply installing an RPM. Please use the command below to install the EPEL repository on your CentOS server.

\#CentOS 6 – 32-bit rpm -Uvh http://mirror.overthewire.com.au/pub/epel/6/i386/epel-release-6-8.noarch.rpm \#CentOS 6 – 64-bit rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86\_64/epel-release-6-8.noarch.rpm

<table> 
 <tbody> 
 <tr> 
 <td> 12345 </td> 
 <td>#CentOS 6 – 32-bitrpm -Uvh http://mirror.overthewire.com.au/pub/epel/6/i386/epel-release-6-8.noarch.rpm&nbsp;#CentOS 6 – 64-bitrpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm</td> 
 </tr> 
 </tbody> 
</table>

Step 2. Install required ClamAV packages.

yum install clamav clamd

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td>yum install clamav clamd</td> 
 </tr> 
 </tbody> 
</table>

Step 3. Start the clamd service on system boot.

chkconfig clamd on service clamd start

<table> 
 <tbody> 
 <tr> 
 <td> 12 </td> 
 <td>chkconfig clamd onservice clamd start</td> 
 </tr> 
 </tbody> 
</table>

Update ClamAV’s signatures:

freshclam

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td>freshclam</td> 
 </tr> 
 </tbody> 
</table>

Step 4. Configuring daily scan.

In this example, I will configure a cronjob to scan the /home/ directory every day:

nano /etc/cron.daily/clamav\_scan

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td>nano /etc/cron.daily/clamav_scan</td> 
 </tr> 
 </tbody> 
</table>

Add following piece of code into clamav\_scan file.

\#!/bin/bash SCAN\_DIR="/home" LOG\_FILE="/var/log/clamav/manual\_clamscan.log" /usr/bin/clamscan -i -r $SCAN\_DIR >> $LOG\_FILE

<table> 
 <tbody> 
 <tr> 
 <td> 1234 </td> 
 <td>#!/bin/bashSCAN_DIR="/home"LOG_FILE="/var/log/clamav/manual_clamscan.log"/usr/bin/clamscan -i -r $SCAN_DIR &gt;&gt; $LOG_FILE</td> 
 </tr> 
 </tbody> 
</table>

Give our cron script executable permissions:

chmod +x /etc/cron.daily/clamav\_scan

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td>chmod +x /etc/cron.daily/clamav_scan</td> 
 </tr> 
 </tbody> 
</table>
