4.DSE

4.DSE Template

This Vagrant template sets up DataStax Enterprise (DSE) on a configurable number of VMs:

• dse[0-n] - DSE nodes (with prerequisites and DSE already installed)

Notes:

• Depending on how much memory your host system has, you may need to lower the default memory size for each VM. Currently it's set to 3GB for each VM.
• This Vagrantfile will install the latest production version of DSE; you could also provide a specific version if you want (adjust the dse-full package version in the apt-get install command).

Instructions

Setup

Bring up the DSE nodes with the following:

$ # optional: adjust DSE_NODES value in Vagrantfile (default 3)
$ vagrant up

When the up command is done, you can check the status of the VMs:

$ vagrant status
Configured for 3 DSE node(s)
Current machine states:

dse0           running (virtualbox)
dse1           running (virtualbox)
dse2           running (virtualbox)

$ vagrant ssh dse0
vagrant@dse0:~$ nodetool status

Configure DSE

The default configuration will join all nodes together into a single cluster (with dse0 as the seed node) and start the services. For reference, see the DataStax Enterprise documentation for all the details on DSE configuration settings.

Mac users might find bcantoni/i2cssh helpful. It will connect with all Vagrant nodes in parallel iTerm2 shell windows: i2cssh -v.

Shut Down

To cleanly shut down all VMs, use the down.sh script:

$ ./down.sh

To destroy all VMs:

$ vagrant destroy -f
