Use this guide to install the singlestoredb-toolbox
and memsql-server
packages and migrate from MemSQL Ops to the SingleStore DB 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 memsql-server
package (which includes the SingleStore DB engine).
Along with these packages, SingleStore also offers a client application through the singlestore-client
package to connect to your SingleStore DB cluster and run queries.
While the /home/<user>/memsql
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
This guide assumes that:
- The SingleStore DB 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 - The SingleStore DB cluster is managed by MemSQL Ops v7.0 or later, which can be verified via
memsql-ops agent-list
(Learn how to upgrade) - The SingleStore DB cluster is running MemSQL 7.0 or later, which can be verified via
memsql-ops memsql-list
(Learn how to upgrade) - SingleStore DB Toolbox v1.3.0 or later, which can be verified via
sdb-toolbox-config version
(Learn how to upgrade)
Ports
Ensure that the following ports are open for use:
Port | Type | For |
---|---|---|
22 | Inbound/Outbound | SSH / SFTP |
80 | Inbound/Outbound | MemSQL Ops |
443 | Inbound/Outbound | SingleStore repository connection |
3306 | Inbound/Outbound | SingleStore DB (default) |
Secure-Shell Access
The installing user must be able to log into each host via ssh
.
