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.

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 rpm, yum, apt, or dpkg. To verify that the cluster was created via package install, run the following commands on the Linux command line.
Red Hat Distribution:
```
sudo yum list --installed | grep memsql-toolbox --or--
sudo yum list --installed | grep singlestoredb-toolbox --or--
rpm -qa | grep memsql-toolbox --or--
rpm -qa | grep singlestoredb-toolbox
```
Debian Distribution:
```
dpkg -s memsql-toolbox | grep Status --or--
dpkg -s singlestoredb-toolbox | grep Status
```
If none of these packages are installed, the cluster was likely deployed via tarball, and so the non-sudo version of the Ops to Tools migration guide should be followed instead.
The user that created the cluster has sudo privileges.
The user performing the migration has 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.
