Downloading Cassandra

Latest version

Cassandra is moving to a monthly release process called Tick-Tock. Even-numbered releases (e.g. 3.2) contain new features; odd-numbered releases (e.g. 3.3) contain bug fixes only. If a critical bug is found, a patch will be released against the most recent bug fix release. Read more about tick-tock here.

Download the latest Cassandra release: {{ “latest” | full_release_link }}.

Older supported releases

The following older Cassandra releases are still supported:

  • Apache Cassandra 3.0 is supported until May 2017. The latest release is {{ “3.0” | full_release_link }}.
  • Apache Cassandra 2.2 is supported until November 2016. The latest release is {{ “2.2” | full_release_link }}.
  • Apache Cassandra 2.1 is supported until November 2016 with critical fixes only. The latest release is {{ “2.1” | full_release_link }}.

Older (unsupported) versions of Cassandra are archived here.

Debian™

The Apache Cassandra project also provide official Debian™ packages (which are not a product of Debian™). To use those packages, you can use:

deb http://www.apache.org/dist/cassandra/debian <release series> main
deb-src http://www.apache.org/dist/cassandra/debian <release series> main

where <release series> is the series you want to install:

  • For tick-tock releases, the <release series> is the release number, without dot, and with an appended x, so 31x, 32x, …
  • For older pre-tick-tock releases, the <release series> is the major version number, without dot, and with an appended x. So currently it can one of 21x, 22x or 30x.

If after running apt-get update, you see an error message like:

GPG error: http://www.apache.org unstable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 0353B12C

you will need to add the public key of the current Cassandra “release manager”, here 0353B12C. You can do that with:

gpg --keyserver pgp.mit.edu --recv-keys <public key>
gpg --export --armor <public key> | sudo apt-key add -

where <public key> is the key to add (0353B12C in the example above). The list of Apache contributors public keys is available at https://www.apache.org/dist/cassandra/KEYS.

Once set up, installing is done as usual with:

sudo apt-get update
sudo apt-get install cassandra

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.

Third party distributions (not endorsed by Apache)

DataStax Distribution of Apache Cassandra is available in Linux rpm, deb, and tar packages, a Windows MSI installer, and a Mac OS X binary.
