Install and Run TypeDB Cluster

Obtaining Commercial License

TypeDB Cluster is a commercial offering that provides a production-grade experience - high-availability, scalability, and security. A license can be obtained from our sales team.

System Requirements

TypeDB Cluster runs on macOS, Linux and Windows. The only requirement is Java (version 11 or higher) which can be downloaded from OpenJDK or Oracle Java.

Download and Install TypeDB Cluster

[tab:Linux] #### Manual Download Download the [latest release](https://repo.vaticle.com/#browse/browse:private-artifact), unzip it in a location on your machine that is easily accessible via terminal. #### Other package managers If TypeDB Cluster doesn't have a distribution you need, please open an issue [on GitHub](https://github.com/vaticle/typedb/issues). Having installed or downloaded TypeDB Cluster, we can now start the [Cluster](#starting-and-stopping-a-single-node-cluster) and interact with the [Console](../console/console). [tab:end] [tab:macOS] #### Manual Download Download the [latest release](https://repo.vaticle.com/#browse/browse:private-artifact), unzip it in a location on your machine that is easily accessible via a terminal. Having installed or downloaded TypeDB, we can now start the [Server](#starting-and-stopping-a-single-node-cluster) and interact with the [Console](../console/console). [tab:end] [tab:Windows] #### Manual Download Download the [latest release](https://repo.vaticle.com/#browse/browse:private-artifact), unzip it in a location on your machine that is easily accessible via a command prompt. Having downloaded TypeDB, we can now start the [Server](#starting-and-stopping-a-single-node-cluster) and interact with the [Console](../console/console). [tab:end] [tab:Docker] #### Using Docker To pull the TypeDB Docker image, run: ``` docker pull vaticle/typedb-cluster:latest ``` #### Without an External Volume For testing purposes, run: ``` docker run --name typedb -d -p 1729:1729 vaticle/typedb-cluster:latest ``` **NOTE:** Running the instance without specifying a volume does NOT save the data if the instance is killed. #### With an External Volume To ensure that data is preserved even when the instance is killed or restarted, run: ``` docker run --name typedb -d -v $(pwd)/db/:/opt/typedb-cluster-all-linux/server/db/ -p 1729:1729 vaticle/typedb-cluster:latest ``` Having started the instance, the TypeDB Cluster is expected to be running on port `1729` on your machine. To interact with the [TypeDB Console](../console/console), run: ``` docker exec -ti typedb bash -c '/opt/typedb-cluster-all-linux/typedb console' ``` [tab:end]

Starting and Stopping a single node Cluster

Starting

If you have installed TypeDB using a package manager, to start the TypeDB Cluster, open a terminal and run typedb cluster.

Otherwise, if you have manually downloaded TypeDB, cd into the unzipped folder and run ./typedb cluster.

Stopping

To stop the TypeDB Cluster, press Ctrl+C in the terminal session you are running TypeDB Cluster from.

Starting and Stopping a multi-node Cluster

Starting

While it’s possible to run TypeDB Cluster in a single-node mode, a truly highly-available and fault-tolerant production-grade setup includes setting up multiple servers to connect and form a cluster. At any given point in time, one of those servers acts as a leader and the others are followers. Increasing the number of nodes increases the Cluster’s tolerance to failure: to tolerate N nodes failing, Cluster needs to consist of 2*N+1 nodes. This section describes how you can set up a 3-node cluster (in this case, one node can fail and no data is lost).

Each node binds to three ports: a client port which TypeDB client drivers connect to (1729), and two server ports (1730 and 1731) for server-to-server communication.

For this tutorial, it’s assumed that all three nodes are on the same virtual network and have the relevant ports open and are uninhibited by any firewall. The nodes have IP addresses 10.0.0.1, 10.0.0.2 and 10.0.0.3 respectively.

[Note] If you're using a single machine to host all nodes, you can prefix the port with the node number; this way the ports `1729`, `1730`, `1731` would turn into `11729`, `11730`, `11731`; `21729`, `21730`, `21731` and so on.

This is how 3-node TypeDB Cluster would be started on three separate machines.

[Note] This guide assumes the application accessing TypeDB Cluster resides on the same private network. If this is *not* the case, TypeDB Cluster also supports using different IP addresses for client and server communication. In order to do so, the relevant external hostname should be passed as arguments using the `--server.address` and `--server.peers` flags as below. ```bash $ ./typedb cluster \ --server.address=external-host-1:1729 \ --server.internal-address.zeromq=10.0.0.1:1730 \ --server.internal-address.grpc=10.0.0.1:1731 \ --server.peers.peer-1.address=external-host-1:1729 \ --server.peers.peer-1.internal-address.zeromq=10.0.0.1:1730 \ --server.peers.peer-1.internal-address.grpc=10.0.0.1:1731 \ --server.peers.peer-2.address=external-host-2:1729 \ --server.peers.peer-2.internal-address.zeromq=10.0.0.2:1730 \ --server.peers.peer-2.internal-address.grpc=10.0.0.2:1731 \ --server.peers.peer-3.address=external-host-3:1729 \ --server.peers.peer-3.internal-address.zeromq=10.0.0.3:1730 \ --server.peers.peer-3.internal-address.grpc=10.0.0.3:1731 ``` and so on. In this case, port `1729` would need to be open to public and clients would use the `external-host-1`, `external-host-2` and `external-host-3` hostnames to communicate with TypeDB Cluster; inter-server communication would be done over a private network using ports `1730` and `1731`.

Stopping

Stopping TypeDB Cluster is done the same way as on a single node: pressing Ctrl+C in the terminal that was used to start it. All nodes must be shut down independently in the same way.

Summary

So far we have learned how to download, install and run TypeDB Cluster in an ad-hoc way.

Next, we’ll learn how to deploy TypeDB Cluster using Kubernetes and Helm.
