Apache's mod_evasive Installation and configuration CentOS,Debian,Ubuntu

Installation on Debian / Ubuntu

The installation of mod_evasive in a Debian / Ubuntu is identical. Before we go any steps further with the installation, make sure you have an up-to date system by issuing:

# apt-get update 

# apt-get upgrade --show-upgraded

Next, install Apache’s module mod_evasive by executing:

# apt-get install libapache2-mod-evasive -y

Once the installation is finished, execute the following commands to configure Apache to use mod_evasive module:

# cat >> /etc/httpd/conf.d/mod_evasive.conf <
DOSHashTableSize 3097
DOSPageCount 5
DOSSiteCount 50
DOSPageInterval 1
DOSSiteInterval 1
DOSBlockingPeriod 60

DOSLogDir /var/log/apache2/evasive

# chown www-data: -R /var/log/apache2/

# /etc/init.d/apache2 restart

---

=> Installation on CentOS 5

First, make sure your CentOS 5  is fully up to date by executing:

# yum update -y

then proceed with adding the EPEL repository to your CentOS 5 so you can install mod_evasive through yum:

# rpm -Uvh ftp://ftp.pbone.net/mirror/download.fedora.redhat.com/pub/fedora/epel/5/i386/epel-release-5-4.noarch.rpm

Once it is added, protect the base packages from EPEL:

# yum install yum-protectbase.noarch -y

Refresh the repositories using:

# yum update -y

and finally install mod_evasive by executing:

# yum install mod_evasive -y

Then, proceed with configuring Apache to use the mod_evasive module:

# echo -e "### LOAD EVASIVE ###\nLoadModule evasive20_module \
 modules/mod_evasive20.so\n###\n" > /etc/httpd/conf.d/mod_evasive.conf

# cat >> /etc/httpd/conf.d/mod_evasive.conf <

=> Installation on CentOS 6

Before installing mod_evasive on your CentOS 6 , make sure your operating system is fully up-to date by running:

# yum update -y

then proceed with adding the EPEL repository to your CentOS 6 so you can install mod_evasive through yum:

# rpm -Uvh ftp://ftp.pbone.net/mirror/download.fedora.redhat.com/pub/fedora/epel/6/i386/epel-release-6-8.noarch.rpm

Once it is added, protect the base packages from EPEL:

# yum install yum-plugin-protectbase.noarch -y

Refresh the repositories using:

# yum update -y

and finally install mod_evasive by executing:

# yum install mod_evasive -y

Then, proceed with configuring Apache to use the mod_evasive module:

# echo -e "### LOAD EVASIVE ###\nLoadModule evasive20_module \
 modules/mod_evasive20.so\n###\n" > /etc/httpd/conf.d/mod_evasive.conf
