Apache Cassandra is a highly scalable, distributed NoSQL database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. It is an open-source project originally developed at Facebook and later released as an Apache project.
To install Apache Cassandra on a Linux server, follow these steps:
Add the Cassandra Repository:
echo "deb http://www.apache.org/dist/cassandra/debian 311x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
Add the Repository Keys:
curl https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -
Update the Package List:
sudo apt-get update
Install Cassandra:
sudo apt-get install cassandra
Start the Cassandra Service:
sudo service cassandra start
Configuration files for Cassandra are located in the /etc/cassandra directory. Key configuration files include:
cassandra.yaml: Main configuration file for Cassandra.cassandra-rackdc.properties: Configuration for data center and rack awareness.logback.xml: Configuration for logging.Regular monitoring and maintenance are crucial for ensuring the optimal performance of a Cassandra cluster. Tools such as nodetool and JMX can be used for monitoring and managing the cluster.
By understanding and leveraging the capabilities of Apache Cassandra, Linux server administrators can effectively manage large-scale, distributed data environments.
