This document handles NebulaGraph installation, and all the operations are done on single hosts.
Firstly, you need to create the config files for the three daemons in the conf directory based on their *.default counterparts.
You could operate on all of the three daemons with scripts/nebula.service:
$ scripts/nebula.service start all
...
$ scripts/nebula.service status all
...
$ scripts/nebula.service stop all
...
$ scripts/nebula.service restart all
...Or, you could do some of the same action on a specific daemon:
$ scripts/nebula.service start metad # Or, scripts/nebula-metad.service start
...
$ scripts/nebula.service status graphd # Or, scripts/nebula-graphd.service status
...
$ scripts/nebula.service restart storaged # Or, scripts/nebula-storaged.service restart
...
