Cloudfoundry grizzly keystone with devstack Install: configparser error in keystone.conf - openstack

Question

I'm trying to install opnstack grizzly on a fresh ubuntu 12.04 server.
The sript runs fin until it reach this point :
screen -S stack -p key -X stuff 'cd /opt/stack/keystone &&
/opt/stack/keystone/bin/keystone-all --config-file /etc/keystone/keystone.con' --log-
config
/etc/keystone/logging.conf -d --debug || touch "/opt/stack/status/stack/key.failure"
2013-07-16 17:33:03 + echo 'Waiting for keystone to start...'

2013-07-16 17:34:03 + set +o xtrace
2013-07-16 17:34:03 [ERROR] ./stack.sh:311 keystone did not start

Bad value substitution:

the parsing instruction :
https://github.com/openstack/keystone/blob/master/keystone/common/config.py
the ConfigParser.InterpolationMissingOptionError :
Exception raised when an option referenced from a value does not exist. Subclass of InterpolationError.
I actually don't understan which option referenced does not exist..
Thank you in advance for your help.

Answer 1

I had the same problem when I ran stack.sh. The localrc file at the time of running stack.sh was:
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service neutron
# enable_service q-lbass
disable_service mysql
enable_service postgresql
# enable_service swift
# SWIFT_HASH=devstack
#
LOGFILE=$DEST/logs/stack.log
SCREEN_LOGDIR=$DEST/logs/screens
#
SERVICE_TOKEN=devstack
SCHEDULER=nova.scheduler.chance.ChanceScheduler
# Repositories
GLANCE_BRANCK=stable/grizzly
HORIZON_BRANCH=stable/grizzly
KEYSTONE_BRANCH=stable/grizzly
NOVA_BRANCH=stable/grizzly
NEUTRON_BRANCH=stable/grizzly
CINDER_BRANCH=stable/grizzly
SWIFT_BRANCH=stable/grizzly
PBR_BRANCH=master
REQUIREMENTS_BRANCH=stable/grizzly
CEILOMETER_BRANCH=stable/grizzly
...
However, after I removed the repositories definition, and let the defaults in stackrc take over, ie. all branches pointed to 'master', the problem went away.
Further, The contents of /opt/stack/keystone/bin/keystone-all script are different between the stable/grizzly and master branches. I think the one in 'master' branch seems to work now withe neutron enabled.

Answer 2

this error because
you run this "stack.sh" as root
or you forget to chmod your config in /etc/keystone/keystone.conf
chmod 777 /etc/keystone/keystone.conf
unstack.sh and then re run stack.sh

Answer 3

just simply
visudo
add stack as user who will do same as root but no password required
stack ALL=(ALL:ALL) ALL
su stack
cp -r /root/devstack /home/stack/
cd /home/stack/devstack/
./stack.sh
clean all first if necessary

Answer 4

Looks like a bug that has been filed for keystone https://bugs.launchpad.net/keystone/+bug/1201861 and it is still open.

Answer 5

Modify devstack/lib/keystone as follows:
iniset $KEYSTONE_CONF DEFAULT public_endpoint "$KEYSTONE_SERVICE_PROTOCOL://$KEYSTONE_SERVICE_HOST:35357/"
iniset $KEYSTONE_CONF DEFAULT admin_endpoint "$KEYSTONE_SERVICE_PROTOCOL://$KEYSTONE_SERVICE_HOST:5000/"

Answer 6

I just ran into this myself. The problem is that DevStack is building a Keystone configuration file in /etc/keystone/keystone.conf in which the option "admin_port" is used before it's been set. And you can't just edit keystone.conf and re-run stack.sh, because your edited version will be overwritten. I'm still chasing down the code that borks the configuration file....
