Installing Cassandra is relatively easy and you can follow few steps to install it. Below are the step that can be followed to install Cassandra on most of the operating systems :

1- Download the Cassandra distribution binaries from the download page.

2- Use the below terminal command to extract the downloaded compressed file:

tar -xvzf datastax-ddc-version_number-bin.tar.gz

3- Now Cassandra is ready to use, you can either use the default configurations or customise the configurations by modifying the file "cassandra.yaml" in the below path:

cd datastax-ddc-version_number/conf

4- Now you can start Cassandra by using the below terminal command:

bin/cassandra

If you are using linux-based systems, then you have also the option to use some package managers to install cassandra such as Yum or apt-get as shown below:

Using apt-get, you need first to add the Cassandra distribution repository to the /etc/apt/sources.list.d/cassandra.sources.list by using the below terminal command:

echo "deb http://debian.datastax.com/datastax-ddc 3.version_number main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list

Then you can use below terminal commands to install Cassandra:

sudo apt-get update

sudo apt-get install datastax-ddc

In a similar way, you can install Cassandra using Yum package manager by first adding the Cassandra distribution repository to the /etc/yum.repos.d/datastax.repo by using below terminal command:

[datastax-ddc]
name = DataStax Repo for Apache Cassandra
baseurl = http://rpm.datastax.com/datastax-ddc/3.version_number enabled = 1
gpgcheck = 0

Then you can easily install it by using below terminal command:

sudo yum install datastax-ddc
