Downloading Cassandra

Java drivers for Cassandra are also available on Maven Central.

Debian and RedHat package repositories have moved!

Debian’s sources.list and RedHat’s cassandra.repo files must be updated to point to the new repository URLs (see below).

Installation from Debian packages

• For the specify the major version number, without dot, and with an appended x.
• The latest is 41x .
• For older releases, the can be one of 40x , 311 , 30x , or 22x .
• Add the Apache Cassandra repository keys:

curl -o /etc/apt/keyrings/apache-cassandra.asc https://downloads.apache.org/cassandra/KEYS

• Add the Apache repository of Cassandra to /etc/apt/sources.list.d/cassandra.sources.list , for example for the latest 4.1

echo "deb [signed-by=/etc/apt/keyrings/apache-cassandra.asc] https://debian.cassandra.apache.org 41x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list

• Update the repositories:

sudo apt-get update

• Install Cassandra:

 sudo apt-get install cassandra

• You can start Cassandra with sudo service cassandra start and stop it with sudo service cassandra stop . However, normally the service will start automatically. For this reason be sure to stop it if you need to make any configuration changes.
• Verify that Cassandra is running by invoking nodetool status from the command line.
• The default location of configuration files is /etc/cassandra .
• The default location of log and data directories is /var/log/cassandra/ and /var/lib/cassandra .
• Start-up options (heap size, etc) can be configured in /etc/default/cassandra .

Installation from RPM packages

• For the `` specify the major version number, without dot, and with an appended x.
• The latest is 41x .
• For older releases, the can be one of 311x , 30x , or 22x .
• (Not all versions of Apache Cassandra are available, since building RPMs is a recent addition to the project.)
• For CentOS 7 and similar (rpm < 4.14), append the noboolean repository
• Add the Apache repository of Cassandra to /etc/yum.repos.d/cassandra.repo , for example for the latest 4.0 version:

[cassandra] name=Apache Cassandra baseurl=https://redhat.cassandra.apache.org/41x/ gpgcheck=1 repo_gpgcheck=1 gpgkey=https://downloads.apache.org/cassandra/KEYS

Or for CentOS 7:

[cassandra] name=Apache Cassandra baseurl=https://redhat.cassandra.apache.org/41x/noboolean/ gpgcheck=1 repo_gpgcheck=1 gpgkey=https://downloads.apache.org/cassandra/KEYS

• Install Cassandra, accepting the gpg key import prompts:

sudo yum install cassandra

Start Cassandra (will not start automatically):

service cassandra start

Systemd based distributions may require to run systemctl daemon-reload once to make Cassandra available as a systemd service. This should happen automatically by running the command above.

Make Cassandra start automatically after reboot:

 chkconfig cassandra on

Please note that official RPMs for Apache Cassandra only have been available recently and are not tested thoroughly on all platforms yet. We appreciate your feedback and support and ask you to post details on any issues in the corresponding Jira ticket.
