Install and run Deephaven with pre-built artifacts
This guide will show you how to install and launch Deephaven Community Core from pre-built artifacts without installing Docker or building from source code.
Prerequisites
This guide is for users who have Linux, Windows WSL, or Mac and have Java 11+ installed.
Get the artifacts
The Deephaven artifacts are attached to each Deephaven release. The latest release is available at https://github.com/deephaven/deephaven-core/releases/latest.
- The server artifact is available in tar format.
- The (optional) Python artifact is available in wheel format.
You can download these artifacts from your browser of choice or via the command line.
For example:
wget https://github.com/deephaven/deephaven-core/releases/download/v0.33.3/server-jetty-0.33.3.tar
wget https://github.com/deephaven/deephaven-core/releases/download/v0.33.3/deephaven_core-0.33.3-py3-none-any.whl
Unpack the server
The server artifact needs to be unpacked. You can do this from your file explorer or from the command line.
For example:
tar xvf server-jetty-0.33.3.tar
Create the virtual environment
Use the following steps to enable Python sessions for your Deephaven Community Core installation. You may skip this section if you only want to use Groovy sessions. (It is possible to switch back and forth between Groovy and Python sessions, but only one may be used at a time.)
When running Deephaven with a Python session, it is recommended to use a virtual environment.
python -m venv deephaven-venv
source deephaven-venv/bin/activate
pip install "deephaven_core-0.33.3-py3-none-any.whl[autocomplete]"
Installing the Deephaven wheel from PyPi is also possible.
pip install "deephaven-core[autocomplete]==0.33.3"
Running the server
The server contains a bin/ directory with a start script. To start the server, invoke the following
command. To use Groovy sessions instead, change python to groovy.
START_OPTS="-Ddeephaven.console.type=python" server-jetty-0.33.3/bin/start
The server should now be up and running with stdout printed to the console and the web UI available at http://localhost:10000.
Congratulations - you are now running the Deephaven server natively!
You can stop the server with Control+C.
Authentication
Deephaven, by default, uses pre-shared key authentication. If no key is set, a randomly generated key will be used to log into the server each time it starts. The randomly generated key is printed to the Docker logs like this:
To set your own pre-shared key, add -Dauthentication.psk=<YourPasswordHere> to the START_OPTS.
START_OPTS="-Dauthentication.psk=YOUR_PASSWORD_HERE" server-jetty-0.33.3/bin/start
