Deploying a Local Databend (for Non-Production Use)

To evaluate Databend and get some hands-on experience, you can deploy Databend locally and use the file system as storage if you don't have object storage yet. This topic explains how to deploy a local Databend and connect to Databend from a MySQL client.

备注

Object storage is required for production. Use the file system only for evaluation, testing, and other non-production purposes.

Before You Begin​

Make sure you have installed a MySQL client.

Download Databend​

  1. Go to https://databend.rs/download and download the installation package for your platform.

    If you're using a Mac with an Apple Silicon CPU, select the package named databend-<version>-nightly-aarch64-apple-darwin.tar.gz.

  2. Extract the installation package to a local directory.

Start Databend​

  1. Open a terminal and navigate to the folder where the extracted files and folders are stored.

  2. Run the script start.sh in the folder scripts:

    MacOS might prompt an error saying "databend-meta can't be opened because Apple cannot check it for malicious software.". To proceed, open System Settings on your Mac, select Privacy & Security on the left menu, and click Open Anyway for databend-meta in the Security section on the right side. Do the same for the error on databend-query.

./scripts/start.sh
  1. Run the following command to verify Databend has been started successfully:
ps aux | grep databend

Connect to Databend​

  1. Create a connection from your MySQL client using port 3307:
mysql -h 127.0.0.1 -P3307 -uroot
  1. Query the Databend version to verify the connection:
SELECT VERSION();
