Cassandra Installation in Mageia – Step-by-step

Installing

2. 2. Downloading Cassandra

   Download Latest Apache Cassandra Release:

   Apache Cassandra tar.gz

   Select the Link to Latest Cassandra tar.gz Release

   Save the File.

3. 3. Setting Up Cassandra

   So now Make Directories
   With:

   sudo mkdir -p /var/log/cassandra/log

   And:

   sudo mkdir -p /var/lib/cassandra/{data,saved_caches,commitlog}

   Creating cassandra User and Group and Adding Users
   Run one by one:

   sudo groupadd cassandra

   sudo useradd cassandra -g cassandra

   And to enable Login Set a Password with:

   sudo passwd cassandra

   Setting Ownership over Directories.

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

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

   Set Permissions over Directories.

   sudo chmod 775 /var/lib/cassandra/data/

   sudo chmod 775 /var/lib/cassandra/saved_caches/

   sudo chmod 770 /var/lib/cassandra/commitlog/

   sudo chmod 770 /var/log/cassandra/log/

4. 3. Installing Cassandra

   Then to Install Cassandra in Mageia
   First, access the Download location by default with:

   cd ~/Downloads

   To Check it’s there List the contents with:

   sudo ls . | grep apache-cassandra

   The grep Command refine the output List showing only the Entries matching the Keyword.
   But if you are in Trouble to Find it out on Terminal then See: How to Access Downloads Folder from Browser.
   Then Extract the Archive directly into Target directory with:

   sudo tar xvzf ./apache-cassandra*.tar.gz -C /opt/

   Now for ease Rename the folder as:

   sudo mv /opt/apache-cassandra* /opt/apache-cassandra

   Again Set the SuperUser as Owner:

   sudo chown -R cassandra:cassandra /opt/apache-cassandra

   Finally, amend the User’s Path:

   echo 'export PATH=$PATH:/opt/apache-cassandra/bin' >> ~/.bashrc

   To Reload it simply run:

   bash

5. 5. Configuring Cassandra

   Edit Cassandra Configuration File
   With nano Editor:

   cd /opt/apache-cassandra

   sudo nano conf/cassandra.yaml

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

   #cluster_name: 'Test Cluster'

   Since no Cluster is made…

   Last, Set Cassandra Log4j Directory

   sudo nano conf/log4j-server.properties

   Append:

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

6. 6. Installing Oracle JDK
