Apache Cassandra is a highly scalable NoSQL database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. In this guide, we will walk you through the steps to install Apache Cassandra on a single-node cluster running Ubuntu 22.04. Whether you are deploying it on a local server or using a , this tutorial covers all the necessary steps.<\/p>\n

\n

Step 1: Update Your System<\/h2>\n

Before installing Cassandra, ensure your system is up to date. Run the following commands:<\/p>\n

sudo apt update && sudo apt upgrade -y<\/code><\/pre>\n
Keeping your system updated is crucial for security and performance, whether you’re setting it up locally or on a VPS Windows VPS Servers<\/a> platform.<\/p>\n<\/section>\n
\n
Step 2: Install Java<\/h2>\n
Apache Cassandra requires Java. Install OpenJDK by running:<\/p>\n
sudo apt install openjdk-11-jdk -y<\/code><\/pre>\n
Verify the Java installation:<\/p>\n
java -version<\/code><\/pre>\n<\/section>\n
\n
Step 3: Add the Cassandra Repository<\/h2>\n
Add the Apache Cassandra repository to your system:<\/p>\n
\r\necho \"deb https:\/\/apache.claz.org\/cassandra\/debian\/ 40x main\" | sudo tee \/etc\/apt\/sources.list.d\/cassandra.sources.list\r\ncurl -fsSL https:\/\/apache.claz.org\/cassandra\/KEYS | sudo apt-key add -\r\n            <\/code><\/pre>\n<\/section>\n
\n
Step 4: Install Cassandra<\/h2>\n
Update the package list and install Cassandra:<\/p>\n
sudo apt update\r\nsudo apt install cassandra -y<\/code><\/pre>\n<\/section>\n
\n
Step 5: Start Cassandra<\/h2>\n
Start the Cassandra service and enable it to run on boot:<\/p>\n
sudo systemctl start cassandra\r\nsudo systemctl enable cassandra<\/code><\/pre>\n<\/section>\n
\n
Step 6: Verify Cassandra Installation<\/h2>\n
You can verify that Cassandra is running by checking its status:<\/p>\n
sudo systemctl status cassandra<\/code><\/pre>\n
You should see the service as “active (running)”.<\/p>\n<\/section>\n
\n
Step 7: Access Cassandra Shell<\/h2>\n
To access the Cassandra Query Language shell (CQLSH), run:<\/p>\n
cqlsh<\/code><\/pre>\n
This will connect you to the default keyspace and allow you to run queries.<\/p>\n<\/section>\n
\n
Step 8: Create a Keyspace<\/h2>\n
You can create a keyspace by running the following command in CQLSH:<\/p>\n
CREATE KEYSPACE my_keyspace WITH REPLICATION = {'class': 'SimpleStrategy', 'replication_factor': 1};<\/code><\/pre>\n
Replace my_keyspace<\/code> with your desired keyspace name.<\/p>\n<\/section>\n
\n
Step 9: Create a Table<\/h2>\n
To create a table within your keyspace, use:<\/p>\n
USE my_keyspace;\r\nCREATE TABLE users (id UUID PRIMARY KEY, name text, email text);<\/code><\/pre>\n<\/section>\n
\n
Step 10: Insert Data into the Table<\/h2>\n
To insert data into your table, run:<\/p>\n
INSERT INTO users (id, name, email) VALUES (uuid(), 'John Doe', 'john@example.com');<\/code><\/pre>\n<\/section>\n
\n
Step 11: Query Data from the Table<\/h2>\n
To query the data you just inserted, use:<\/p>\n
SELECT * FROM users;<\/code><\/pre>\n<\/section>\n
