Setup a multinode Cassandra using Ubuntu 12.04 and Virtualbox

1. Setup virtual machines (3 for exmaple)

You should first setup one machine using virtualbox, setup JAVA environment, download the Cassandra source code
Use Virtualbox’s virtualmanager function to copy another two ubuntu machines. Make sure to modify the hostname.
Modify the /etc/hosts file.
Machine summary
- 192.168.56.101 sjhadoop0
- 192.168.56.103 sjhadoop1
- 192.168.56.104 sjhadoop2

2. Config Cassandra

Modify /conf/cassandra-env.shfile.

  MAX_HEAP_SIZE=&quot;512M&quot;
  HEAP_NEWSIZE=&quot;128M&quot;

Modify /conf/cassandra.yaml file. For each virtual machine, change listen_address and rpc_addressaccordingly.
```
  listen_address: 192.168.1.1
  rpc_address: 192.168.1.1
```
Choose one first machine as seed. Then change seeds to its ip address, make the rest VM pointing to the same seed.
```
  seeds: - 192.168.1.1
```
Assign initial_token, using the this python code to generate initial token and modify the initial_token in .yaml file.

3. Start Cassandra

	sudo ./bin/cassandra -f

That’s it!!
