You have two options to implement a high-availability solution when you install MySQL 5.7.18 or higher (64-bit) using MySQL Installer:
Standalone MySQL Server / Classic MySQL Replication (default)
Select this option to begin the initial configuration of a standalone MySQL server. You can configure multiple servers with classic MySQL Replication manually or use MySQL Shell to configure a production InnoDB cluster.
Sandbox InnoDB Cluster Setup (for testing only)
Select this option to create and configure sandbox InnoDB cluster instances locally for testing. You can configure a sandbox InnoDB cluster to have three, five, seven, or nine MySQL server instances. Use the Reconfigure quick action in the MySQL Installer dashboard to adjust the number of instances in the InnoDB cluster after the configuration has finished.Note
Existing instance ports (3310 to 3390), which may have been set for a sandbox InnoDB cluster manually using MySQL Shell, will be deleted by MySQL Installer if you run the sandbox InnoDB cluster test setup.
As the following figure shows, this step requires that you enter a password for the MySQL
rootaccount. The password strength is evaluated when you retype it.
The sandbox InnoDB cluster, named
sandboxCluster by default, is available on
selected ports. After the configuration executes, click the
Summary tab to view the specific ports that
apply to your cluster. Sandbox InnoDB cluster configuration
entries are stored in the
You can use MySQL Installer to install MySQL Shell, if it is not installed. MySQL Shell enables you to manage the sandbox instances. To connect with the MySQL Shell on port 3310, execute the following command:
MySQL Installer also provides a wizard for configuring MySQL Router to connect to the test InnoDB cluster that was created in this step. For configuration details, see MySQL Router Configuration. To learn more about MySQL Router operations, see Routing for MySQL InnoDB cluster.
