CACSS Cloud Storage System

  • Neither of Amazon S3’s architecture nor its implementation has yet been made public. As such, it is not available for extension in order to develop the capability of creating private clouds of any size. In order to reveal this secret knowledge behind cloud storage services and thereby a generic solution, we present CACSS, a generic computational and adaptive cloud storage system that adapts existing storage technologies to provide efficient and scalable services.
  • CACSS Cloud Storage System is built as the implementation of one of my papers CACSS: Towards a Generic Cloud Storage Service (In: The 2nd International Conference on Cloud Computing and Services Science, CLOSER 2012, Porto, Portugal. Pages 27-36,SciTePress 2012, ISBN 978-989-8565-05-1.)
  • It is Amazon S3 API Compatible (you only need to change the endpoint from to
  • Currently deployed across a bunch of virtual machines.
  • Some functions such as object versioning is currently disabled.
  • Please feel free to contact me for any questions you may have.

How to install PostgreSQL 9.2 on RHEL/CentOS/Scientific Linux 5 and 6

First, download PostgreSQL 9.2 repo package from here. Please pick up the correct repo file per your distro and architecture. If you are not sure about your OS version, run

cat /etc/redhat-release

Install the repo RPM. For example, if you downloaded repo RPM for RHEL 6, here is your command:

rpm -ivh pgdg-redhat92-9.2-7.noarch.rpm

Alternatively, you can install the package directly by using the repo RPM URL:

rpm -ivh

Now, you can install PostgreSQL 9.2 with single command:

yum groupinstall “PostgreSQL Database Server PGDG”

This will install PostgreSQL 9.2 server, along with -contrib subpackage. If you don’t want -contrib subpackage, you can use

yum install postgresql92-server

to install 9.2 on your machine. Once it is installed, first initialize the cluster:

service postgresql-9.2 initdb

Now, you can start PostgreSQL 9.2:

service postgresql-9.2 start

If you want PostgreSQL 9.2 to start everytime on boot, run this:

chkconfig postgresql-9.2 on
