Automatically configure master databases

NOTE

This feature is available for Adobe Commerce instances only.

IMPORTANT

The split database feature was deprecated in version 2.4.2 of Adobe Commerce. See Revert from a split database to a single database.

This topic discusses how to get started with the split database solution by:

  1. Installing Adobe Commerce with a single master database (named magento)
  2. Creating two additional master databases for checkout and OMS (named magento_quote and magento_sales)
  3. Configuring Adobe Commerce to use the checkout and sales databases
INFO

This guide assumes that all three databases are on the same host as the Commerce application and that they are named magento, magento_quote, and magento_sales. However, the choice of where to locate the databases and what they are named is up to you. We hope our examples make the instructions easier to follow.

Install the Adobe Commerce software

You can enable split databases at any time after you install the Adobe Commerce software; in other words, you can add split databases to an Adobe Commerce system that already has checkout and order data. Use the instructions in the Adobe Commerce README or the installation guide to install the Adobe Commerce software using a single master database.

Set up additional master databases

Create checkout and OMS master databases as follows:

  1. Log in to your database server as any user.

  2. Enter the following command to get to a MySQL command prompt:

    mysql -u root -p

  3. Enter the MySQL root user’s password when prompted.

  4. Enter the following commands in the order shown to create database instances named magento_quote and magento_sales with the same usernames and passwords:

    create database magento_quote;

    GRANT ALL ON magento_quote.* TO magento_quote@localhost IDENTIFIED BY 'magento_quote';

    create database magento_sales;

    GRANT ALL ON magento_sales.* TO magento_sales@localhost IDENTIFIED BY 'magento_sales';

  5. Enter exit to quit the command prompt.

  6. Verify the databases, one at a time:

    Checkout database:

    mysql -u magento_quote -p

    exit

    Order management system database:

    mysql -u magento_sales -p

    exit

    If the MySQL monitor displays, you created the database properly. If an error displays, repeat the preceding commands.

Configure Commerce to use the master databases

After setting up a total of three master databases, use the command line to configure Commerce to use them. (The command sets up database connections and distributes tables among the master databases.)

First steps

See Running commands to log in and run CLI commands.

Configure the checkout database

Command syntax:

bin/magento setup:db-schema:split-quote --host="<checkout db host or ip>" --dbname="<name>" --username="<checkout db username>" --password="<password>"

For example,

bin/magento setup:db-schema:split-quote --host="localhost" --dbname="magento_quote" --username="magento_quote" --password="magento_quote"

The following message displays to confirm a successful setup:

Migration has been finished successfully!

Configure the OMS database

Command syntax:

bin/magento setup:db-schema:split-sales --host="<checkout db host or ip>" --dbname="<name>" --username="<checkout db username>" --password="<password>"

For example,

bin/magento setup:db-schema:split-sales --host="localhost" --dbname="magento_sales" --username="magento_sales" --password="magento_sales"

bin/magento setup:upgrade

The following message displays to confirm a successful setup:

Migration has been finished successfully!
