Hi. After I installed grafana-image-renderer plugin with Grafana CLI.
grafana-server service can’t be started by unknown reason. The error message is “permission denied”. But permission seems to be OK.

Could you please tell me what is the problem?
Thanks for any help or pointers.

What Grafana version and what operating system are you using?
grafana-server 7.5.11 on Oracle Linux Server 8.6

What are you trying to achieve?
grafana-server service start

How are you trying to achieve it?
grafana-server service start

What happened?
First, grafana-server service could be started. But it couldn’t be started by unknown reason after I installed grafana-image-renderer plugin with Grafana CLI.
“permission denied” was written in grafana.log. But permission seems to be OK.

What did you expect to happen?
grafana-server service start

Can you copy/paste the configuration(s) that you are having problems with?
No config change

Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.

Hi @gont,

Welcome to the :grafana: community forum !!

Not sure if you are still having this issue or already resolved it.

You can have a look at the documentation on how to troubleshoot the Image rendering plugin.
