Re: How to start/stop/restart services in devstack

 

This actually is something I wanted to verify.
What are the reasons sudo won't work?
Apache running seems to be the only reason for that? Also the fact that config files are written to privileged locations (/etc/apache2...), volume group commands and such.
In the newer devstack I am working on sudo should work since the process of installing (to any location u pick) and then starting is separated (and the apache user/group is configurable) but I just wanted to double check this.

stack.sh doesn't run as root so sudo is incorrect.
it runs as local user or if you ran it as root originally, it will create a user called stack change to that user and rerun itself.
(which means you will need to do sudo su stack; screen -x)

If it isn't running as the stack user, you probably just need to rerun it.
