Hi  Rgds,

Very thanks for you quickly rely.
I try restart blow services. But I can’t start lava-server-gunicorn service.
But my lava project has /etc/lava-server-gunicorn service and lava-server-gunicorn service.service file.

Subject: Re: [Lava-users] How to restart LAVA server master service after LAVA server host restart

Hello,

LAVA services are the following:
* on the master:
** lava-server-gunicorn: the web UI
** lava-master
** lava-logs: the logs handler
** lava-publisher: the event publisher
** postgresql: the database
** apache2: the main web server (serving static content, ...)

* on the slave (or on the master for a signal instance setup):
** lava-slave

All these services can be started/stopped/restarted using the "service" command.
For example "service lava-master restart" will restart the master (if ran as root!).

Hi LAVA team,

I meet one critical error.
We restart our LAVA server host machine. We can’t know how to restart our LAVA server service.

Could you tell me how to restart LAVA server master service with detail steps? Thanks!
The LAVA server is not installed by us. So we are not clear about this.
