Hi guys!
Thanks for responding last time. A couple of follow-up questions:
1.) The rabbit_host I define in trove.conf, trove-conductor.conf,
trove-taskmanager.conf, this is a Rabbit host that is contactable by
both the Trove services and the Trove DB instances, right? I mean, I
don't need the Trove services to be able to contact the other OpenStack
services via Rabbit? If they DO need to, can you suggest a "basic" setup
for that?
Can be a completely separate rabbit AFAICS.
2.) When I run
http://tarballs.openstack.org/trove/images/ubuntu/mysql.qcow2 as an
instance, how do I access the CLI? Is there a default username/password?
How do I configure it to access the RabbitMQ that it is supposed to
contact Trove services through?
You use the trove database and user mgmt commands, e.g (from my
Juno/Kilo notes...):
$ trove list
+--------------------------------------+------+-----------+--------+-----------+------+
| id | name | datastore | status |
flavor_id | size |
+--------------------------------------+------+-----------+--------+-----------+------+
| 95ae7758-a3d7-49e1-b6be-d36e6f79df00 | db1 | mysql | ACTIVE |
7 | 2 |
+--------------------------------------+------+-----------+--------+-----------+------+
# should actually do a 'trove show 95ae7758-a3d7-49e1-b6be-d36e6f79df00'
above to get the ip address (sorry)
$ trove database-create 95ae7758-a3d7-49e1-b6be-d36e6f79df00 db
$ trove user-create 95ae7758-a3d7-49e1-b6be-d36e6f79df00 user password
--databases db
$ mysql -h 10.0.0.2 -u user -p db
mysql> CREATE TABLE tab(id integer PRIMARY KEY, val text);
Query OK, 0 rows affected (0.37 sec)
3.) Pertaining to the Disk Image Builder, the instructions at
http://docs.openstack.org/developer/trove/dev/building_guest_images.html
tell me that "This command will create a guest image usable by Trove:"
export HOST_USERNAME
export HOST_SCP_USERNAME
export GUEST_USERNAME
export NETWORK_GATEWAY
export REDSTACK_SCRIPTS
export SERVICE_TYPE
export PATH_TROVE
export ESCAPED_PATH_TROVE
export SSH_DIR
export GUEST_LOGDIR
export ESCAPED_GUEST_LOGDIR
export
ELEMENTS_PATH=$REDSTACK_SCRIPTS/files/elements:$PATH_TRIPLEO_ELEMENTS/elements
export DIB_CLOUD_INIT_DATASOURCES="ConfigDrive"
local QEMU_IMG_OPTIONS=$(! $(qemu-img | grep -q 'version 1') && \
echo "--qemu-img-options compat=0.10")
${PATH_DISKIMAGEBUILDER}/bin/disk-image-create -a amd64 -o "${IMAGE_NAME}" \
-x ${QEMU_IMG_OPTIONS} ${DISTRO} ${EXTRA_ELEMENTS} \
vm heat-cfntools cloud-init-datasources ${DISTRO}-guest \
${DISTRO}-${SERVICE_TYPE}
I made this as an .sh file and ran it. DIB would die because I did not
set values for the "export" lines above. But, there are no explanations
in the documentation as to what the variables mean. For example, what
should I put as SSH_DIR? What's "ESCAPED_PATH_TROVE" for? What should I
put as its value? A lot of lacking little details that yet are important
discouraged me from trying to build my own image.
I used:
$ export ESCAPED_PATH_TROVE=`echo $PATH_TROVE | sed 's/\//\\\\\//g'`
$ export SSH_DIR=${HOMEDIR}/.ssh
$ export ESCAPED_GUEST_LOGDIR=`echo $GUEST_LOGDIR | sed 's/\//\\\\\//g'`
again for Juno/Kilo branch...hopefully there are not too many new ones
to *guess* values for!!!
Thanks for the help!!! I'm about to tear my hair out over this.
Yeah, we need to do better with documenting the details here...I feel
your pain
Cheers
Mark
