Installing Cassandra 3.8 on Debian Jessie

Intro

Cassandra is highly available (no SPOF) distributed database service for managing large amounts of structured data across many commodity servers.

Here is a quick recipe for starting a first Debian based Cassandra server in your Cassandra cluster.

 

Modify Debian repositories

 

• Modify default apt sources and make sure you have Contrib in sources:

# vim /etc/apt/sources.list
deb http://http.debian.net/debian jessie main contrib non-free
deb-src http://http.debian.net/debian jessie main contrib non-free
deb http://http.debian.net/debian jessie-updates main contrib non-free
deb-src http://http.debian.net/debian jessie-updates main contrib non-free
deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

 

• Add Cassandra to sources:

# vim /etc/apt/sources.list.d/cassandra.list
deb http://www.apache.org/dist/cassandra/debian 37x main
deb-src http://www.apache.org/dist/cassandra/debian 37x main

 

Install Oracle Java JDK

Visit Oracle website and download Oracle JDK tar.gz package from Oracle website

http://www.oracle.com/technetwork/java/javase/downloads/index.html

 

 Install Java and Cassandra

sudo -i
apt-get update && apt-get install java-package && exit
apt install libgl1-mesa-glx libgtk2.0-0 libxxf86vm1 -y
make-jpkg jdk-8u51-linux-x64.tar.gz
dpkg -i oracle-java8-jdk_8u91_amd64.deb
update-alternatives --config java # and choose Oracle version
apt-get install cassandra -y

 

Is it running?

# systemctl status cassandra

Working with Cassandra

cqlsh
nodetool status
nodetool info
nodetool tpstats

Example output:

$ cqlsh
