Replacing a MemSQL License min read

This page describes how to replace your MemSQL license.

Using MemSQL Ops With Internet Access

In MemSQL Ops, navigate to Settings > Licenses. From that screen, you can add a new MemSQL license. MemSQL Ops will then update all nodes in your MemSQL cluster asynchronously to use the new license.

Or you can use the CLI LICENSE-ADD command to add a new license:

$ memsql-ops license-add --license-key <license key>

Using MemSQL Ops Without Internet Access

If you need to replace your MemSQL license and you do not have internet access, you will have to use the <license-file> argument instead of the above <license key> argument. For this to work, the license file will need to be on the host with the primary memsql-ops agent.

Use memsql-ops agent-list to check which node is the primary agent.

Then use the following command to add a new license:

memsql-ops license-add --license-file </path/to/file>

Without MemSQL Ops

This process is configuration error prone and we recommend that you use MemSQL Ops to update your license instead. Only use this option if MemSQL Ops is unavailable.

  1. On each node in your cluster, replace the existing license in <MEMSQL_HOME>/lib with your new license.
  2. On each node in your cluster, run:
$ sudo service memsql update-license <path to new license>

MemSQL Ops does not allow the addition of 3.2 licenses into MemSQL 4+ nodes.

MemSQL licenses issued before the MemSQL 4 launch may still work with MemSQL 4. That said, we recommend that users update their license to a new MemSQL license when possible.
