[Cassandra]: Overview andInstallation

Prerequisites :
=============

Latest version of Oracle Java SE Runtime Environment (JRE) 7.
Java Native Access (JNA) is required for production installations (latest version recommended).
Python 2.6+ (needed if installing OpsCenter).
If you are using an older RHEL-based Linux distribution, such as CentOS-5, you may see the following error: GLIBCXX_3.4.9 not found.
You must replace the Snappy compression/decompression library (snappy-java-1.0.5.jar) with the snappy-java-1.0.4.1.jar.
Download your copy from any of below links :

http://www.apache.org/dyn/closer.cgi?path=/cassandra/2.1.2/apache-cassandra-2.1.2-bin.tar.gz
http://downloads.datastax.com/community/dsc-2.0.tar.gz

Procedure :
=========

In a terminal window:

Check which version of Java is installed by running the following command:
$ java -version

Use the latest version of Oracle Java 7 on all nodes.

Download the DataStax Community:
$ curl -L http://downloads.datastax.com/community/dsc-2.0.tar.gz | tar xz

 
Check Download DataStax Community Edition on Planet Cassandra for the latest version.

You can also download from Planet Cassandra. Go to the install directory:
$ cd dsc-cassandra-2.0.x

The DataStax Community distribution of Cassandra is ready for configuration

Initializing a multiple node cluster (single data center)

You can initialize a Cassandra cluster with a single data center.

Prerequisites :
==============

Each node must be correctly configured before starting the cluster. You must determine or perform the following before starting the cluster:

A good understanding of how Cassandra works. Be sure to read at least Understanding the architecture, Data replication, and Cassandra’s rack feature.
Install Cassandra on each node.
Choose a name for the cluster.
Get the IP address of each node.
Determine which nodes will be seed nodes. Do not make all nodes seeds. (Cassandra nodes use the seed node list for finding each other and learning the topology of the ring.)
Determine the snitch and replication strategy. The GossipingPropertyFileSnitch and NetworkTopologyStrategy are recommended for production environments.
If using multiple data centers, determine a naming convention for each data center and rack, for example: DC1, DC2 or 100, 200 and RAC1, RAC2 or R101, R102.
Choose the name carefully; renaming a data center is not possible.
Other possible configuration settings are described in The cassandra.yaml configuration file and property files such as cassandra-rackdc.properties.

This example describes installing a 6 node cluster spanning 2 racks in a single data center.
Each node is configured to use the GossipingPropertyFileSnitch and 256 virtual nodes (vnodes).

In Cassandra, the term data center is a grouping of nodes.
Data center is synonymous with replication group, that is, a grouping of nodes configured together for replication purposes.
