ERROR while creating compute.rhino3d on Windows Server 2016

eissamail · November 5, 2019, 3:31pm

Hi All,

I was following this article in order to create compute.rhino3d on our server:
https://github.com/mcneel/compute.rhino3d/blob/master/docs/installation.md

After finishing all steps from 1 to 6 successfully, I tried to run step 7 and I am getting this error:

Could anyone help me with that?

Thanks in advance.

Thanks but is there any solution for this problem?

@eissamail FYI–It was moved to the appropriate category so your post could be indexed/tagged to get a better response.

It seems like something else is already listening on the ports that Compute wants to use.

You can use netstat -o -n -a to find out what’s running.

Hi Will,

The server we using is a small web server for our intranet web applications (internal use).

Is there anyway that let us run this alongside with the XAMPP?

Thanks.

UPDATE: On the server we use MS SQL Server, XAMPP, MySQL.

You can configure the ports that Compute uses via environment variables.

At the least it looks like you’ll need to set COMPUTE_HTTP_PORT to something other than the default of 80 (sounds like it might be conflicting with Apache).

Hi Will,

Thanks for your reply.

In the link you provide it says the variable name that I need to change, but it did not say where I should do the changes and the config file name.

Could you please tell me the name and the path of the config file?

Thanks.

Kind regards,

~A

will · November 6, 2019, 3:15pm

Compute is configured with environment variables. There is no configuration file.

A brief guide to setting environment variables in Windows.

Note: If you’re running compute.frontend.exe from a Command Prompt/Powershell, you’ll need to close the window and open a new one to get it to use the new environment variable(s).

Hi Will,

Thanks for your reply.

I think this should be clarified in the documentation, as it let me understand from the way it is written that there is a configuration file.

Thanks.

Kind regards,

Hi Will,

I did the changes, and still see errors:

It looks like something else is using port 8081 (the default port for the backend geometry service). Try changing this by setting COMPUTE_BACKEND_PORT to an unused port.

I appreciate your feedback here, but environment variables are already well documented throughout the internet. That said, I’ve added the link that I shared above to the documentation.
