SingleStoreDB v8.1

Introduction

Use this guide to install the singlestoredb-toolbox and singlestoredb-server packages and migrate from MemSQL Ops to the SingleStoreDB management tools for cluster management. The migration tool automates most of the migration process.

SingleStore Tools allow you to perform cluster management operations for setup, configuration, and diagnostics. Operations are done through CLI commands which can be easily scripted for use in a variety of deployment environments and scenarios.

Most of the tools are part of the singlestoredb-toolbox package. However, the lower-level management tool, memsqlctl, is part of the singlestoredb-server package (which includes the SingleStoreDB engine).

Along with these packages, SingleStore also offers a client application through the singlestore-client package to connect to your SingleStoreDB cluster and run queries.

Note

While the /home/<user>/singlestore directory is used through this guide to hold the necessary migration files and demonstrate the associated migration commands, this directory can be substituted with any directory that a non-sudo user has access to.

Prerequisites

Warning

This guide assumes that your cluster is running MemSQL v7.0 or later, which can be verified via memsql-ops memsql-list.

If your cluster is running an earlier version of MemSQL, it will be upgraded to MemSQL v7.0 as part of this migration.

In addition, this guide assumes:

  • The SingleStoreDB cluster components were installed via tarball

  • The user that created the cluster does not have sudo privileges

  • The user performing the migration does not have sudo privileges

  • A root password has been set on all nodes in the cluster Learn how to set root password.

  • The SingleStoreDB cluster is managed by MemSQL Ops v7.0 or later, which can be verified via memsql-ops agent-list Learn how to upgrade.

  • SingleStoreDB Toolbox v1.3.0 or later, which can be verified via sdb-toolbox-config version Learn how to upgrade.
