Installing Apache mod_bw in Ubuntu Linux

Bandwidth module (mod_bw) is not a default option in the Apache installation under Ubuntu Linux. The following are the steps to have bandwidth module enabled in Apache web server:

• (Optional) If you may want to download wget and apxs2 to be able to download and compile mod_bw.

  # sudo apt-get install wget apache2-threaded-dev

• Download and compile mod_bw.

  # wget http://ivn.cl/files/source/mod_bw-0.8.tgz
  
  
  
  # tar xvzf mod_bw-0.8.tgz
  # cd mod_bw
  # apxs2 -i -a -c mod_bw.c

  I am assuming that you get this error:

  apxs:Error: Activation failed for custom /etc/apache2/httpd.conf file..
  
  
  
  apxs:Error: At least one `LoadModule’ directive already has to exist..

  Yes, it is expected. Just ignore the error.

• Create the load file.

  # cd /etc/apache2/mods-available
  
  
  
  # sudo sh -c "echo 'LoadModule bw_module /usr/lib/apache2/modules/mod_bw.so' > bw.load"
  
  
  
  # cd ../mods-enabled
  
  
  
  # ln -s ../mods-available/bw.load bw.load

• Add Bandwidth Configuration to your Virtualhost, for example:

  <Virtualhost *>
  
  
  Servername www.example.com
  BandwidthModule On
  ForceBandWidthModule On
  Bandwidth all 1024000
  MinBandwidth all 50000
  LargeFileLimit * 500 50000
  </Virtualhost>

  <Virtualhost *>
  Servername www.example.com
  BandwidthModule On
  ForceBandWidthModule On
  Bandwidth all 10240
  MinBandwidth all -1
  LargeFileLimit * 500 50000
  </Virtualhost>

  For more examples, please visit mod_bw setup.

• Restart apache2 to activate the bandwidth module.

  # /etc/init.d/apache2 restart
