When installing grafana and influxDB. I encountered the folowing issue
The service of grafana and influxDB where not starting .
I checked using rcconf that my service where enabled , and they where !
I then tried sysv-rc-conf and my service where correctly configured !
the services had absolutely no issue starting when called manually and started fine !
this line was telling me that the service startup was disabled !
after seaching a bit on the web ,the solution to this issue is using systemctl to enables the services.
