Cassandra Nutanix Opensource

Single node Cassandra on Ubuntu 18.10

Ayan Kumar Nath
5 years Ago

Nutanix uses Cassandra as it’s metadata store. But what if we needed a Cassandra node locally – on our local machine – Cassandra, essentially, is an OpenSource project, so technically, it should be possible to install Cassandra locally, right?

Well let’s try a Cassandra installation on my local machine running Ubuntu!

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.10
Release:	18.10
Codename:	cosmic

Cassandra actually needs Java as a pre-requisite. So the workflow is pretty simple

  • Install Java
  • Get the repos for Cassandra going
  • Install Cassandra
  • Ensure we can bring up a single node
  • Connect to the Cassandra DB and ensure you are able to connect

So let’s go about installing and see how far we get. I am running Ubuntu 18.x

Check if Java is installed – skip if there is Java installed already

$ java version

Command 'java' not found, but can be installed with:

sudo apt install openjdk-11-jre-headless
sudo apt install default-jre            
sudo apt install openjdk-8-jre-headless

So we don’t have Java installed on this machine. Let’s go about installing Java 8.x. For that, let’s first add the repos. As the message below says, you will need to choose the appropriate repo for the version of Java you need. For this example, we are going with Java 8x

$ sudo add-apt-repository ppa:webupd8team/java
 Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK8). There are no actual Java files in this PPA.

Oracle JDK 8 installed

#####Important########
To set Oracle JDK8 as default, install the "oracle-java8-set-default" package.
E.g.: sudo apt install oracle-java8-set-default
On Ubuntu systems, oracle-java8-set-default is most probably installed
automatically with this package.

Cool! No errors. Let’s check the status of Cassandra

$ sudo service cassandra status

Nodetool

$ sudo nodetool status

Now, let’s try connecting to the DB

$ cqlsh

cqlsh> exit

So we now have a local Cassandra running – we are able to connect, read tables and also check the nodetool status!

Let’s create a cluster – in the next post and see if we can get a three node cluster up and running and read/write some data off the tables
