5. Why Tarball?

6. RPM / DEB / APT / TAR / Docker ???
RPM / DEB / APT (Packages)
1. Great if you are all bought into the
package management system.
2. Great if you host your own
repositories for DEB/RPM/APT etc in
your enterprise.
3. Great because it’s easy.
4. Not great if you don’t have control
over the system to manage packages.
TARBALL
1. Great if you know what you are
doing.
2. Great if you don’t have root access
but need to run things.
3. Great if you want to be able to switch
between versions of Cassandra
4. No general downsides except that
you can’t do “yum update …” etc.

7. Prerequisites

8. Apache Cassandra 4.0 Prerequisites / Install

a. Java 11 is experimental.
2. Python 2.7 or Above (python --
version)
cd /opt/
curl -OL http://apache.mirror.digitalpacific.com.au/cassandra/4.0.0/apache-cassandra-4.0.0-

logs/
pylib/
tools/
● Bin: location of the commands to run cassandra, cqlsh,
nodetool, and SSTable tools
● Conf: location of cassandra.yaml and other configuration
files
● Data: location of the commit logs, hints, and SSTables
● Logs: location of system and debug logs
Tools: location of cassandra-stress tool

10. Start Cassandra

11. Start Cassandra
$ cd apache-cassandra-4.0.0/ && bin/cassandra
$ tail -f logs/system.log
See if it’s up
$ bin/nodetool status
$ bin/cqlsh

12. Apache Cassandra Configuration Files

● cluster_name: Set the name of your cluster.
● seeds: A comma separated list of the IP addresses of your cluster seed nodes.
● storage_port: Check that you don’t have the default port of 7000 blocked by a firewall.
● listen_address: The listen address is the IP address of a node that allows it to communicate
with other nodes in the cluster. Set to localhost by default.
● native_transport_port: Check that you don’t have the default port of 9042 blocked by a
firewall, so that clients like cqlsh can communicate with Cassandra on this port

13. Configure Cassandra
