How to Install ClamAV on CentOS 7 About ClamAV ClamAV is free open-source antivirus software that is used often and across several platforms. In this tutorial, we are going to teach you how to install ClamAV on CentOS 7. Prerequisites For this tutorial you are going to need: SSH root access to the VPS. Step 1 — Installing ClamAV on CentOS 7 Since Clam does not come with default CentOS software reports, you need to add the additional repository by running yum. yum -y install epel-release yum clean all Now install Clam on CentOS. Simply execute the command below. yum -y install clamav-server clamav-data clamav-update clamav-filesystem clamav clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd You have now installed antivirus software on your server. Step 2 — Configuring SELinux SELinux is a security measure whose purpose it is to protect changes to certain files. You will need to perform futher configuration if you would like to use ClamAV with enabled SELinux kernel module. Without this, Clam is not able to read a portion of your files. Simply run the commands below. setsebool -P antivirus_can_scan_system 1 setsebool -P clamd_use_jit 1 To confirm these changes, execute the following command. getsebool -a | grep antivirus You should be receiving the output below or similar. antivirus_can_scan_system --> on antivirus_use_jit --> off Once this output is received, ClamAV is ready to use along with SELinux. Step 3 — Configuring ClamAV Before the Clam Configuration can be enabled, you have to remove the Example string from the configuration file. sed -i -e "s/^Example/#Example/" /etc/clamd.d/scan.conf Now, you will have to specify the server type. Open the configuration file with your favorite editor. In our example, we are going to use nano. If it isn’t currently installed, it must be installed with yum. yum install nano -y Open the configuration file. nano /etc/clamd.d/scan.conf Then, look for the following line. #LocalSocket /var/run/clamd.scan/clamd.sock Replace it with the line below. LocalSocket /var/run/clamd.scan/clamd.sock You may now save the changes by pressing on CTRL + X or COMMAND + X (If you are using a MAC). Before finishing you must delete the Example string from ClamAV’s freshclam update engine configuration file. sed -i -e "s/^Example/#Example/" /etc/freshclam.conf Then, execute the virus definition database update. freshclam You should be receiving the output below or similar. ClamAV update process started at Tue Dec 19 09:30:20 2016 main.cvd is up to date (version: 57, sigs: 4218790, f-level: 60, builder: amishhammer) Trying host database.clamav.net (126.96.36.199)...
