Legacy Licensing¶
Before you start¶
Goal
- License the Altair SLC Hub.
Prerequisites
- Follow the initial install instructions.
- Altair SLC Hub configuration privileges for the host.
- Access to a license file.
Install the Altair SLC Hub licence key¶
By default, the Altair SLC Hub licence key is read from the file [var directory]\licence.txt.
The location from which the licence key is read is controlled by the licence.keyfile configuration property
and can be changed if required. For details on the operation of the configuration process and how configuration files are read, see Configuration.
The license key is delivered as a text string. Edit the licence key file and paste the licence key text into it.
The permissions on the [var directory] directory require that this file be edited by a user that is part of the slchub group.
For example, to edit the file with vi, type the following command:
vi [var directory]/licence.txt
Once the file is created and saved, ensure that the correct ownership and permissions are set.
The file should be owned by the install user, with the group set to slchub.
The permissions should be set to read/write by owner and group, not accessible to others, that is 0660, or --rw-rw----.
These settings ensure that only the Hub service processes can read the licence file, while any workloads that Hub may run cannot.
Once the file is created and saved, ensure the correct access controls are set to prevent normal users accessing and reading then file. To do this it is necessary to disable access control inheritance for the file and then set the access control list so that the Administrators group has Full Control, the SYSTEM user has Read access.
Verification¶
Verify licence
- run the hubctl verify licence command
Before continuing it is necessary to verify that the licence has been installed correctly
This can be done using the hubctl commands, as follows:
hubctl verify licence
