Installed plugin does not appear in console plugin list

I installed the simple react panel (https://github.com/grafana/simple-react-panel) and it does not appear in the plugin list on the Grafana console after restarting grafana-server.

Prior to this I installed Node.js (v12.18.3), yarn (v1.22.4), and node-sass (4.14.1), copied the folder simple-react-panel-master into the default plugin directory /var/lib/grafana/plugins, and specified the default directory in the config file grafana.ini under [paths].

Inside folder ‘/var/lib/grafana/plugins/simple-react-panel-master’ I did the commands ‘yarn install’ and ‘yarn build’:

[root@ip-10-56-248-220 20200810 21:16:11 simple-react-panel-master]# yarn instal l
yarn install v1.22.4

Then I restarted grafana-server and verified from the Grafana log that the plugin was registered :

Also verified plugin was installed locally:
[root@ip-10-56-248-220 20200810 21:25:21 simple-react-panel-master]# grafana-> cli plugins ls

installed plugins:
myorgid-simple-panel @ 1.0.0
Restart grafana after installing plugins .

Then checked plugin list on console and the new plugin was not listed.

Issue was resolved. Required setting ownership permission recursively to the installed plugin folders, as well as making sure all instances in system that were running Grafana used same configuration for console.

Commands:

chown -R grafana:grafana /var/lib/grafana/plugins
chmod -R 700 /var/lib/grafana/plugins
