How to Install Mod_Evasive in RHEL/CentOS & Fedora

As we already installed required dependency packages above, so let’s install the mod_evasive module.

Step 1: Installing Mod_Evasive

Just run the following commands to install mod_evasive.

## For RHEL/CentOS 6.2/6.1/6/5.8 ##
# cd /usr/src 
# wget
# tar xzf mod_evasive_1.10.1.tar.gz
# cd mod_evasive
# apxs -cia mod_evasive20.c## For Fedora 17,16,15,14,13,12 ##
# cd /usr/src 
# wget
# tar xzf mod_evasive_1.10.1.tar.gz
# cd mod_evasive
# apxs -cia mod_evasive20.c

Step 2: Configuring Mod_Evasive

By default installation adds the following line of mod_evasive configuration to your Apache configuration file. Please verify that it should be there like similar to below. If you can’t see this below line, then add this to your httpd.conf file.

LoadModule evasive20_module   /usr/lib/httpd/modules/

Now add the mod_evasive configuration parameters to your Apache configuration at the end. Replace [email protected] with your Email Id to get email alerts.

DOSSiteCount        50
