Installing Cassandra 2.0 on Ubuntu

Update your apt source list with the following:

sudo vim /etc/apt/sources.list

#Add at the bottom
deb http://www.apache.org/dist/cassandra/debian 20x main
deb-src http://www.apache.org/dist/cassandra/debian 20x main

Run an apt-get update. 

 sudo apt-get update

This will give you a warning about not being able to verify the signatures of the apache repos:

GPG error: http://www.apache.org unstable Release:
The following signatures couldn't be verified because the public key is not available:
NO_PUBKEY 4BD736A82B5C1B00

Now do the following for that key:

gpg --keyserver pgp.mit.edu --recv-keys 4BD736A82B5C1B00
gpg --export --armor 4BD736A82B5C1B00 | sudo apt-key add -

Also add this one:

gpg --keyserver pgp.mit.edu --recv-keys 2B5C1B00
gpg --export --armor 2B5C1B00 | sudo apt-key add -

Now run apt-get update again.
sudo apt-get update

The error should be gone. Now check that all is working and UBuntu can see Cassandra 2.0:

apt-cache showpkg cassandra
Package: cassandra
Versions:
2.0.1

Great! Now install it:

sudo apt-get install cassandra

Now start it:
sudo service cassandra start
xss = -ea -javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1001M -Xmx1001M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss256k

Now you can check you can connect:
cqlsh
Connected to Test Cluster at localhost:9160.
[cqlsh 4.0.1 | Cassandra 2.0.1 | CQL spec 3.1.1 | Thrift protocol 19.37.0]
Use HELP for help.

Where is everything?

  • Logs: /var/log/cassandra
  • Config: /etc/cassandra/
  • Data: /var/lib/cassandra


Done!
