OpenStack Compute (nova)

How to stop some nova services from restarting when starting up

Asked by arturo lorenzo

I am running all services in one node and I am planning to split the nova services. How can I stop some of the nova services like nova-compute or nova-objectstore from restarting every time we reboot?
Should we uninstall them? apt-get remove nova-compute? or is there an easy way like in other Linux platforms? i.e. chkconfig
thanks

All the nova PPA packages use upstart scripts:

You should be able to disable the services you want by editing the files in /etc/init and commenting out the 'start on' lines.

Tools like chkconfig are available on Ubuntu but I don't think they currently support disabling upstart scripts. Hope this helps.

Getting a tool like chkconfig that works with upstart would be great.

To see the state of init scripts you can also do a 'initctl list'.
