This section describes how to install Crate on a single node. In order to get a Crate cluster up and running it is enough to repeat the process on another machine if the network supports multicast. The Nodes will discover and form a cluster automatically. Just like magic.
In case the network doesn’t support multicast, a unicast configuration is required. Please refer to our article on Multi Node Setup in order to learn how to setup the unicast configuration.
We recommend installing Java 8 update 20 or later.

Docker is a lightweigt runtime to run distributed applications in a sandboxed container. We provide a Docker image for Crate for easy installation:
sh$ docker pull crate sh$ docker run -d -p 4200:4200 -p 4300:4300 crate crate -Des.cluster.name=my_cluster
We provide distributions for RHEL/YUM based systems, Ubuntu, Debian and Arch Linux.
You can find instruction how to install Crate for production on the Download page.
In case your distribution is missing feel free to contact us. We’re happy to create and maintain additional packages if we see enough interest.
