Step 3

LoadModule cband_module /usr/lib/httpd/modules/mod_cband.so

Check the LoadModule of 'mod_cband' is added or not in httpd.conf

<VirtualHost *:80 *:443>
DocumentRoot /var/www/html/test
ServerName www.test.com
CBandSpeed 1024 50 100
CBandRemoteSpeed 20kb/s 3 3
</VirtualHost>

<Location /cband-status>
SetHandler cband-status
</Location>
<Location /cband-status-me>
SetHandler cband-status-me
</Location>

Append the codes in the end of httpd.conf file.

The CBandSpeed directive limits the overall Apache performance for the www.example.com vhost to a speed of 1024kbps, max. 50 requests per second and max. 100 open connections.

The CBandRemoteSpeed is like the CBandSpeed directive, but it sets limits for any individual user. to a speed of 20kbps, max. 3 requests per second and max. 3 open connections.
