The FME Flow Core and the FME Flow Engines system services use the local system account by default on Windows, and the fmeserver account on Linux. You may wish to run the FME Flow Engines service under a different account that can read and write data across a network, particularly in a distributed installation where this service is installed on separate machines.
- Add or identify a new user account that will run the FME Flow Engines service.
- Windows: To ensure the integrity of your overall file system, this user should belong to a standard account that is part of the "Users Group," rather than an Administrator. For example, this user could be called "FMEEngineUser." Be sure to create a password for this user.
- Linux: Typically, you can create a new user with the command adduser <username> , and follow the prompts. For example:
- Grant the necessary permissions to the account identified above to the FME Flow System Share and the FME Flow install directory. For more information, see Directory and Account Permissions.
- On the Resources page of the Web User Interface, delete all files and folders located under Logs > engine. This step is necessary to allow the new user account to write to the engine log. Before you delete, use the Download button to archive any logs you want to keep.
- Update the account that logs on to the FME Flow Engines service to the new user:
- Windows:
- Grant "Log on as a service" rights to this account. For more information, see this Microsoft Docs article.
- For more information, see Running the FME Flow System Services Under Different Accounts (Windows).
- Linux: Start FME Flow by calling the
startServer.shscript in the Server directory with the root user. This starts the FME Flow Core as the user that installed FME Flow, and the FME Flow Engines as the new engine user. If you are using the Linux startup scripts, no further setup is required, and on the next restart, the Engines will start under the engine user.
