barnraising

This Project is provided by Chris Lesniewski-Laas and M. Frans Kaashoek for reducing the bandwidth load on Web servers. the thesis is public and Demo Program is open source code. We can access thesis and download the Demo

But both thesis and demo have not specific installed document. I had met a lot of problems, sometimes I had to modify the source code. After 3 weeks later, I finally install and run successfully. I wrote the process of installing to this file, and this git reposity is my modified and successful barnraising version. My modified Version of Barnraising is here

the demo component

• Cache Proxy
• broker.pl: simple managed daemon
• minion.pl: forward the user https request to webSite, get url content request from expander daemon and save content to local disk

• Mysql database: record dns zone information

• WebSite

• expander.pl: response minion request for url content request
• apache_1.3.23: the standard httpd program
• OpenSSL0.9.6g: code at openssl directory in barnraising. In https handshake phase, It save url content to local disk
• domain and https certificate: I use my domain zhouds.cn to test

the installed environment

• Two physical Devices or VMs
• Cache Proxy: Linux OS is Centos5.8 + Kernel 2.6.18-308.el5 + Perl5.8.8 + Mysql
• WebSite: Linux OS is RHLr 8.0 + Kernel 2.4.18-14 + Perl5.8.0 + OpenSSL0.9.6 + Apache1.3.22

  Crypt::DES
  Crypt::DES_EDE3
  Crypt::CBC  ( whose tests depend on Crypt::Rijndael )
  Inline
  Inline::C

Step 3: run perl script

#./configure --with-ssl=../barnraising/openssl --with-apache=../apache_1.3.22 --prefix=/usr/local/apache-split
# make 
# make install
# cp ../barnraising/httpd.conf /usr/local/apache-split/conf/
# /usr/local/apache-split/bin/apachectl startssl

Step 3: run perl script

# perl expander.pl 
# 

Run and good luck
