I dont seem to get the apache error anymore

/usr/share/slurm-web/restapi/slurm-web-restapi.wsgi' cannot be loaded as Python module.

I had to change "/etc/apache2/conf-available/slurm-web-restapi.conf" from

WSGIScriptAlias /slurm-restapi /usr/share/slurm-web/restapi/slurm-web-restapi.wsgi

to

WSGIScriptAlias /slurm-restapi /usr/share/slurm-web/restapi/

However I'm getting a new error as below

[client 10.10.223.249:58097] Target WSGI script not found or unable to stat: /usr/share/slurm-web/restapi/cluster

Any help is appreciated. Thanks

Hi. Have you solved this problem?

[mehdid]

I am not sure where the issue is but I can confirm that WSGIScriptAlias /slurm-restapi has to be set to /usr/share/slurm-web/restapi/slurm-web-restapi.wsgi.

[BigDataHealthcare]

I am running the container and slurmctld ruuning on same host. so i am using [] in clusters.config.json. But i am getting following error.

To fix the issue i have tried the solution mentioned in issue - #183 , but no success.

Could please help me to resolve issue.

This issue concerns Slurm-web v2 which is not maintained anymore. You are highly encouraged to test the new version v3.0.0 that is not impacted by this issue. The quick start guide for v3.0.0 is available online: https://docs.rackslab.io/slurm-web/install/quickstart.html

Unless someone is motivated to maintain the old version of Slurm-web or you have a justified reason to keep this issue open, it will be closed in a few weeks.

[rezib]

For the reasons explained in the previous comment, I finally close this issue.
