Run a multi node server
Run a multi-node, scalable cluster with TiKV
For highly-available and highly-scalable setups, SurrealDB can be run on top of a TiKV cluster, with the ability to horizontally scale to 100+ terabytes of data. In this example, we will start a local TiKV cluster with a single node, for development and testing purposes only. To install TiKV on your development machine, run the following command. This will install the
tiup command-line tool, which enables deploying and managing TiKV clusters of any size.
curl -sSf https://tiup-mirrors.pingcap.com/install.sh | sh
Once installed we shall start up a simple single-node development cluster.
tiup playground --tag surrealdb --mode tikv-slim --pd 1 --kv 1
Once TiKV is up and running, we can start a SurrealDB server instance, specifying the TiKV cluster endpoint as the backing data store.
surreal start tikv://127.0.0.1:2379
The default logging level for the database server is
info, resulting in any informational logs to be output to the standard output. To control the logging verbosity, specify the
--log argument. The following command starts the database with
trace level logging, resulting in most logs being output to the terminal.
surreal start --log trace tikv://127.0.0.1:2379
In order to keep SurrealDB secure, configure your initial root-level user by setting the
--pass command-line arguments. The following command starts the database with a top-level user named root with a password also set to
root. The root user will be persisted in storage, which means you don't have to include the command line arguments next time you start SurrealDB.
surreal start --log trace --user root --pass root tikv://127.0.0.1:2379
In order to change the default port that SurrealDB uses for web connections and from database clients you can use the
--bind argument. The following command starts the database on port
surreal start --log trace --user root --pass root --bind 0.0.0.0:8080 tikv://placement.driver.hostname.or.ip:2379
After running the above command, you should see the SurrealDB server startup successfully.
surreal start --user root --pass root --bind 0.0.0.0:8080 file:mydatabase.db
