ping cassandra on virtualbox guest from windows host

I'm using virtual box to act as Linux guest to Cassandra DB, and I'm trying to access it through my windows host, however, i don't know what are the right configurations to do that.

on virtual box I'm using "host only networking" to communicate from windows.

Anyone knows how to do these configurations?

Access Cassandra on Guest VM from Host OS

For future reference to myself and others, this worked for me for Cassandra v3.10:

http://grokbase.com/t/cassandra/user/14cpyy7bt8/connect-to-c-instance-inside-virtualbox

Once your Guest VM is provisioned with Cassandra, I had a host only network adapter set with IP 192.168.5.10.

Then had to modify /etc/cassandra/cassandra.yaml to set:

From

rpc_address: localhost

To

rpc_address: 192.168.5.10

Then run sudo service cassandra restart and give it 15 seconds...

Then on the guest VM or on the host the following worked:

cqlsh 192.168.5.10

Hope that helps someone.

Vagrantfile for reference

Note it doesn't work for multiple nodes in a cluster yet

# Adjustable settings
## Cassandra cluster settings
mem_mb = "3000"
cpu_count = "2"
server_count = 1
network = '192.168.5.'
first_ip = 10

servers = []
seeds = []
cassandra_tokens = []
(0..server_count-1).each do |i|
  name = 'cassandra-node' + (i + 1).to_s
  ip = network + (first_ip + i).to_s
  seeds << ip
  servers << {'name' => name,
              'ip' => ip,
              'provision_script' => "sleep 15; sudo sed -i -e 's/^rpc_address: localhost/rpc_address: #{ip}/g' /etc/cassandra/cassandra.yaml; sudo service cassandra restart;",
              'initial_token' => 2**127 / server_count * i}
end

# Configure VM server
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu/xenial64"
  servers.each do |server|

    config.vm.define server['name'] do |x|
      x.vm.provider :virtualbox do |v|
        v.name = server['name']
        v.customize ["modifyvm", :id, "--memory", mem_mb]
        v.customize ["modifyvm", :id, "--cpus"  , cpu_count  ]
      end
      x.vm.network :private_network, ip: server['ip']
      x.vm.hostname = server['name']
      x.vm.provision "shell", path: "provision.sh"
      x.vm.provision "shell", inline: server['provision_script']

    end
  end
end

provision.sh

So you are trying to connect to Cassandra from Linux guest in your virtualbox? Or is it the other way around?

Anyways, whatever the direction make sure that you IP is reachable and that the Cassandra ports are open (start with 9042).

Maybe, it's the network configuration of the guest. In VirtualBox environment, if you want communicate to the guest from the host, the network type of the VM must be "bridged networking" or "host only networking".

You can find more information here : https://www.virtualbox.org/manual/ch06.html.
