How-to Install Apache Cassandra on Linux Fedora Easy Guide

Apache Cassandra Overview:

• Proven: Cassandra is in use at eBay, CERN, GitHub, Netflix and over 1500 more companies.
• Fault Tolerant: Data is automatically replicated to multiple nodes for fault-tolerance.
• Performant: Cassandra consistently outperforms popular NoSQL alternatives in benchmarks and real applications.
• Decentralized: there are no single points of failure. There are no network bottlenecks. Every node in the custer is identical.
• Durable: Cassandra is suitable for applications that can’t afford to lose data, even when an entire data center goes down.
• You’re in Control: Choose between synchronous or asynchronous replication for each update.
• Elastic: Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.
• Professionally Supported: Cassandra support contracts and services are available from third parties.

1. Open a Shell Terminal emulator window
   Start Typing ‘term’ on Desktop.
   (Press “Enter” to Execute Commands)

   

2. Download Latest Apache Cassandra Release:

   Apache Cassandra tar.gz

   Select the Link to Latest Cassandra tar.gz Release.
3. Double-Click on Archive and Extract Cassandra into /tmp
   
   Or from Shell:

   tar xvzf apache-cassandra*.bin.tar.gz -C /tmp/

4. LogIn as SuperUser

   sudo su

   If Got “User is Not in Sudoers file” then Look: Solution

5. Relocate Cassandra Directory

   mv /tmp/apache-cassandra* /var/lib/cassandra

6. Make Needed Directories

   mkdir -p /var/log/cassandra/log

   mkdir /var/lib/cassandra/{data,saved_caches,commitlog}

7. Creating cassandra Group and Adding Users

   groupadd cassandra

   usermod -a -G cassandra [yourUser]

   usermod -a -G cassandra root

8. Setting Ownership over Directories

   chown -R root:cassandra /var/lib/cassandra/

   chown -R root:cassandra /var/log/cassandra/

9. Set Permissions over Directories

   chmod 775 /var/lib/cassandra/data/

   chmod 775 /var/lib/cassandra/saved_caches/

   chmod 770 /var/lib/cassandra/commitlog/

   chmod 770 /var/log/cassandra/log/

10. Edit Cassandra Configuration File

    cd /var/lib/cassandra

    nano conf/cassandra.yaml

    Append:

    • data_file_directories:
       - /var/lib/cassandra/data

    • commitlog_directory: /var/lib/cassandra/commitlog

    • saved_caches_directory: /var/lib/cassandra/saved_caches

    Then Search and Comment Out:
    (Ctrl+w to Search on nano)

    #cluster_name: 'Test Cluster'

    Since no Cluster is stille in work…

11. Set Cassandra Log4j Directory

    nano conf/log4j-server.properties

    Append:

    log4j.appender.R.file=/var/lib/cassandra/log/system.log

12. Required Oracle-Sun Official Java JDK 8 for Fedora:

    Oracle JDK 8 Installation for Fedora

    Installing Oracle JDK 8 on Fedora Linux Desktops.

13. Exit from SuperUser Session

    exit

14. Start Cassandra Instance

    ./bin/cassandra

15. Check Connection to Cassandra Instance with nodetool

    ./bin/nodetool --host 127.0.0.1 ring

Then Thanks to the Apache Software Foundation You are Able to Getting-Started with NoSQL Database Apache Cassandra on Fedora Linux.
