Cassandra | Setup

We learnt about Cassandra in previous post. We will setup and run client on an Cassandra cluster(fully distributed) here.

Installation

For installation we will use three nodes. We will install fully distributed Cassandra cluster. Here we are using following details for installation (for complete setup):

• Installation base directory:

• /home/anishsneh/installs

• Installation user name:

• anishsneh

• Hostnames: 

• server01 (first node, say with ip address 172.16.70.131)
• server02 (second node, say with ip address 172.16.70.132)
• server03 (third node, say with ip address 172.16.70.133)

Note that in Cassandra there is NO SINGLE POINT OF FAILURE, hence all the nodes are equal and there is no MASTER or SLAVE.

• Install Cassandra
• Download Apache Cassandra binary from Apache Website.
• Extract downloaded package to /home/anishsneh/installs, such that we have:

  [anishsneh@server01 installs]$ ls -ltr apache-cassandra-2.1.5/
  total 360
