How to install mod_evasive on Linux server ?

mod_evasive is an evasive maneuvers module for Apache that provides evasive action in the event of an HTTP DoS attack or brute force attack. It is also designed to be a detection and network management tool, and can be easily configured to talk to ipchains, firewalls, routers, and more.

Go to the below path.

cd /usr/local/src

Download the file using the below link:

wget wget http://www.zdziarski.com/blog/wp-content/uploads/2010/02/mod_evasive_1.10.1.tar.gz

Untar the file.

tar xzf mod_evasive_1.10.1.tar.gz

Go to the folder.

cd mod_evasive

Run the below command for the installation.

apxs -cia mod_evasive20.c

You’ll then need to add the mod_evasive configuration to your Apache configuration file. First, find this section:

File:/etc/httpd/conf/httpd.conf (CentOS / Fedora)

LoadModule evasive20_module /usr/lib/httpd/modules/mod_evasive20.so

Below those sections, add the mod_evasive configuration:

File excerpt:mod_evasive configuration

DOSHashTableSize 3097
DOSPageCount 2
DOSSiteCount 50
