Before installing Cassandra make sure the following prerequisites are met:
The packaged releases create a cassandra user. When starting Cassandra as a service, the service runs as this user.
Check which version of Java is installed by running the following command in a terminal window:
Use the latest version of Java 6 on all nodes. Java 7 is not recommended. If you need help installing Java, see Installing the JRE on RHEL or CentOS Systems.
(RHEL 5.x/CentOS 5.x only) Make sure you have EPEL (Extra Packages for Enterprise Linux) installed. EPEL contains dependent packages required by DSE, such as jna and jpackage-utils. For both 32- and 64-bit systems:
$ sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
Add a yum repository specification for the DataStax repository in /etc/yum.repos.d. For example:
$ sudo vi /etc/yum.repos.d/datastax.repo
In this file add the following lines for the DataStax repository:
[datastax] name= DataStax Repo for Apache Cassandra baseurl=http://rpm.datastax.com/community enabled=1 gpgcheck=0
Install the package using yum.
$ sudo yum install dsc1.1
This installs the DataStax Community distribution of Cassandra and the OpsCenter Community Edition.
