Use following steps to do it.
cd /usr/local/src
wget http://www.zdziarski.com/projects/mod_evasive/mod_evasive_1.10.1.tar.gz
tar -zxf mod_evasive_1.10.1.tar.gz

If you are adding the is module to apache 1.3.x the following lines need to be added to the httpd.conf below the AddModule section.
<IfModule mod_evasive.c>
DOSHashTableSize 3097
DOSPageCount 5
DOSSiteCount 100
DOSPageInterval 2
DOSSiteInterval 2
DOSBlockingPeriod 600
</IfModule>
If you are using apache 2.0.x you need to scroll to below the LoadModule section in the httpd.conf and add the following:
<IfModule mod_evasive20.c>
DOSHashTableSize 3097
DOSPageCount 5
DOSSiteCount 100
DOSPageInterval 2
DOSSiteInterval 2
DOSBlockingPeriod 10
DOSBlockingPeriod 600
</IfModule>
Exit and save out of the httpd.conf
Now it should be ready to go. Exit out of pico and restart apache.
