"Mod_bandwidth" is a module for the Apache webserver that enables the setting of server-wide or per connection bandwidth limits, based on the directory, size of files and remote IP/domain. Installing this module involves a number of steps, but it is fairly simple to accomplish.

SSH into your server as root and perform the following:

Code: 
mkdir /root/modbw

cd modbw

wget ftp://ftp.cohprog.com/pub/apache/module/1.3.0/mod_bandwidth.c

/usr/local/apache/bin/apxs -c /root/mbw/mod_bandwidth.c -o /usr/local/apache/libexec/mod_bandwidth.so
(The above is all one command)

mkdir /usr/local/apache/apachebw

mkdir /usr/local/apache/apachebw/link

mkdir /usr/local/apache/apachebw/master

chown nobody:nobody -R /usr/local/apache/apachebw

pico /etc/httpd/conf/httpd.conf
Find the line that looks like this:

LoadModule rewrite_module libexec/mod_rewrite.so

And BEFORE that line, add this:

LoadModule bandwidth_module libexec/mod_bandwidth.so

Then locate the line that looks like this:

AddModule mod_env.c
and BEFORE that line, add this:

AddModule mod_bandwidth.c

Then locate the line that looks like this:

# Document types.
And BEFORE that line add this:

BandWidthDataDir "/usr/local/apache/apachebw"
BandWidthModule On
Then to enable it on a virtual host, locate the virtualhost entry for the
domain you wish to limit and just BEFORE the </virtualhost> line, add
this:

BandWidthModule On
BandWidth all 512
The 512 can be replaced with whatever rate you want to limit it to in
bytes per second.

Save the httpd.conf file.

Code: 
service httpd restart
Code: 
cd /usr/sbin
Code: 
wget ftp://ftp.cohprog.com/pub/apache/module/cleanlink.pl
Code: 
chmod 755 cleanlink.pl
Code: 
pico cleanlink.pl
Change $LINKDIR as follows:

Code: 
$LINKDIR="/usr/local/apache/apachebw/link";
Save the file.

Code: 
perl cleanlink.pl
Code: 
pico /etc/rc.d/rc.local
At the end of that file add:

# Launch Cleanlink for mod_bandwidth
Code: 
perl /usr/sbin/cleanlink.pl
Save that file.

There is actually a lot more you can do with this module than simply limiting the bandwidth rates. You can limit the number of connections, file sizes and more. I encourage you to read the documentation located here for all the deatils of everything you can sutomize with this module.
