When installing grafana and influxDB. I encountered the folowing issue

The service of grafana and influxDB where not starting .

service grafana-server status
grafana-server.service - Starts and stops a single grafana instance on this system
Loaded: loaded (/usr/lib/systemd/system/grafana-server.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: http://docs.grafana.org

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 !

loaded (/usr/lib/systemd/system/grafana-server.service; disabled;

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.

systemctl enable grafana-server.service
systemctl enable influxdb.service
