3. Installing Cassandra
Then to Install Cassandra in Fedora
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. 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. Installing Oracle JDK
Required Oracle-Sun Official Java JDK for Fedora
Please be aware that Cassandra 4 support only Java 8 &.
