Official Package To Install On Debian(tm) (not a product of Debian(tm))

Add the following lines to /etc/apt/sources.list:

deb 30x main
deb-src 30x main

You will want to replace 30x by the series you want to use: 22x for the 2.2.x series, 21x for the 2.1.x series, etc... You will not automatically get major version updates unless you change the series, but that is a feature.

Adding Repository Keys

If you run apt-get update and see an error similar to this:

GPG error: unstable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F758CE318D77295D

This simply means you need to add a PUBLIC_KEY for Apache Cassandra deb releases. The Apache Cassandra committer's public keys are available at

To add the KEYS file to apt in one command (may be repeated on existing installs, if you see an error similar to above, and the new Release Manager keys will be fetched):

curl | sudo apt-key add -

sudo apt-key list should show the following keys added, along with the base OS keys:

Alternative Key Fetching

If you wish to manually add an individual committer's key, apt-key can fetch from a keyserver, as follows, using the long key ID:
(Michael Shuler's key was added to KEYS on 2016-09-23, so releases after this date may be signed with FE4B2BDA)

Install Apache Cassandra

sudo apt-get update
sudo apt-get install cassandra
sudo apt-get install cassandra-tools  # optional utilities

Some things to be aware of:

  • The configuration files are located in /etc/cassandra
  • Start-up options (heap size, etc) can be configured in /etc/default/cassandra

Building Packages on Debian

Once all the build dependencies are set up, all you need to do is run

dpkg-buildpackage -uc -us


Make sure you are building with the Oracle JDK, not OpenJDK, and not gcj. You want to see something like this:

$ java -version
java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

By default, installing the Cassandra Debian package or its build dependencies will pull in OpenJDK. For runtime purposes this will work fine, but you may wish to install Oracle JRE, which is outside the scope of this document.|stats
