Grafana service fails to start on EC2 Linux

Hello,

I am running into this issue where the grafana server does not start up at all.

This was working fine until i made a change to the grafana.ini file but again reverted the change i made and restarted the service. Ever since, i have been seeing this following message

ash: go: command not found
[root@ip-10-191-115-68 bin]# sudo journalctl -u grafana-server -f

While i tried to look up logs, i dont see anything that seems relevant to thwe change made and revrted.

Only way to temporarily load the dashboard is by this way - sudo /usr/sbin/grafana-server --config=/etc/grafana/grafana.ini --homepath=/usr/share/grafana

Kindly note - i am using V9.3.6 and on an ec2 linux machine

Inputs on how to resolve this would be much appreciated.

Checking /var/logs/grafana.log indicate this as errors

logger=settings t=2023-08-29T19:53:30.237101568Z level=error msg="failed to parse \"/etc/grafana/grafana.ini\": open /etc/grafana/grafana.ini: permission denied"

Unsure what the permissions must look like

Current permissions look like this

root@ip-10-191-115-68 grafana]# ls -l /etc/grafana/grafana.ini
-rw-r-----. 1 root grafana 37557 Aug 29 16:48 /etc/grafana/grafana.ini
