Pre-Flight Check
  • These instructions are intended for installing Cassandra 2 on a single Fedora 20 node.
  • I’ll be working from a Liquid Web Self Managed Fedora 20 server, and I’ll be logged in as root.
  • You may be able to skip to Step #2 if you already have a stable version of Java 7 (preferably the Oracle/Sun JVM). Check to see if your server already has Java installed by running the following command: java -version
 
Step 1: Install Java
First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new. yum -y update At this point, installing java is as simple as running just one command: yum -y install java
Step #2: Add the DataStax Community Repository
For a refresher on editing files with vim see: New User Tutorial: Overview of the Vim Text Editor vim /etc/yum.repos.d/datastax.repo Add the following information to the file you’ve created, using i to insert: [datastax] name = DataStax Repo for Apache Cassandra baseurl = http://rpm.datastax.com/community enabled = 1 gpgcheck = 0 Then exit and save the file with the command :wq (see the example below): How To Install Cassandra 2 and Run a Single Node Cluster on CentOS 6 - 02 DataStax Repo
Step #3: Install Apache Cassandra 2
