Install and configure controller node
|
|
=====================================
|
|
|
|
This section describes how to install and configure the Telemetry
|
|
module, code-named ceilometer, on the controller node. The Telemetry
|
|
module uses separate agents to collect measurements from each OpenStack
|
|
service in your environment.
|
|
|
|
To configure prerequisites
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Before you install and configure Telemetry, you must install ``MongoDB``,
|
|
create a MongoDB database, service credentials, and API endpoint.
|
|
|
|
.. only:: obs
|
|
|
|
1. Enable the Open Build Service repositories for MongoDB based on
|
|
your openSUSE or SLES version:
|
|
|
|
On openSUSE:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper addrepo -f obs://server:database/openSUSE_13.2 Database
|
|
|
|
On SLES:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper addrepo -f obs://server:database/SLE_12 Database
|
|
|
|
.. note::
|
|
|
|
The packages are signed by GPG key ``562111AC05905EA8``.
|
|
You should verify the fingerprint of the imported GPG key before
|
|
using it.

|
Key Expires: Sat Dec 20 20:08:39 2014
|
|
|
|
Install the MongoDB package:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper install mongodb
|
|
|
|
.. only:: rdo
|
|
|
|
1. Install the MongoDB package:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install mongodb-server mongodb
|
|
|
|
.. only:: ubuntu
|
|
|
|
1. Install the MongoDB package:
|
|
|
|
.. code-block:: console
|
|
|
|
# apt-get install mongodb-server mongodb-clients python-pymongo
|
|
|
|
.. only:: obs
|
|
|
|
2. Edit the :file:`/etc/mongodb.conf` file and complete the following
|
|
actions:
|
|
|
|
a. Configure the ``bind_ip`` key to use the management interface
|
|
IP address of the controller node.
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
bind_ip = 10.0.0.11
|
|
|
|
b. By default, MongoDB creates several 1 GB journal files
|
|
in the :file:`/var/lib/mongodb/journal` directory.
|
|
If you want to reduce the size of each journal file to
|
|
128 MB and limit total journal space consumption to 512 MB,
|
|
assert the ``smallfiles`` key:
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
smallfiles = true
|
|
|
|
You can also disable journaling. For more information, see the
|
|
`MongoDB manual <http://docs.mongodb.org/manual/>`__.
|
|
|
|
c. Start the MongoDB services and configure them to start when
|
|
the system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable mongodb.service
|
|
# systemctl start mongodb.service
|
|
|
|
.. only:: rdo
|
|
|
|
.. The use of mongod, and not mongodb, in the below screen is intentional.
|
|
|
|
2. Edit the :file:`/etc/mongod.conf` file and complete the following
|
|
actions:
|
|
|
|
a. Configure the ``bind_ip`` key to use the management interface
|
|
IP address of the controller node.
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
bind_ip = 10.0.0.11
|
|
|
|
b. By default, MongoDB creates several 1 GB journal files
|
|
in the :file:`/var/lib/mongodb/journal` directory.
|
|
If you want to reduce the size of each journal file to
|
|
128 MB and limit total journal space consumption to 512 MB,
|
|
assert the ``smallfiles`` key:
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
smallfiles = true
|
|
|
|
You can also disable journaling. For more information, see the
|
|
`MongoDB manual <http://docs.mongodb.org/manual/>`__.
|
|
|
|
c. Start the MongoDB services and configure them to start when
|
|
the system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable mongod.service
|
|
# systemctl start mongod.service
|
|
|
|
.. only:: ubuntu
|
|
|
|
2. Edit the :file:`/etc/mongodb.conf` file and complete the following
|
|
actions:
|
|
|
|
a. Configure the ``bind_ip`` key to use the management interface
|
|
IP address of the controller node.
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
bind_ip = 10.0.0.11
|
|
|
|
b. By default, MongoDB creates several 1 GB journal files
|
|
in the :file:`/var/lib/mongodb/journal` directory.
|
|

|
|
assert the ``smallfiles`` key:
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
smallfiles = true
|
|
|
|
If you change the journaling configuration, stop the MongoDB
|
|
service, remove the initial journal files, and start the service:
|
|
|
|
.. code-block:: console
|
|
|
|
# service mongodb stop
|
|
# rm /var/lib/mongodb/journal/prealloc.*
|
|
# service mongodb start
|
|
|

|
|
`MongoDB manual <http://docs.mongodb.org/manual/>`__.
|
|
|
|
.. only:: obs or ubuntu
|
|
|
|
3. Create the ``ceilometer`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
# mongo --host controller --eval '
|
|
db = db.getSiblingDB("ceilometer");
|
|
db.addUser({user: "ceilometer",
|
|
pwd: "CEILOMETER_DBPASS",
|
|
roles: [ "readWrite", "dbAdmin" ]})'
|
|
|
|
MongoDB shell version: 2.4.x
|
|
connecting to: controller:27017/test

],
|
|
"_id" : ObjectId("5489c22270d7fad1ba631dc3")
|
|
}
|
|
|
|
|
|
Replace ``CEILOMETER_DBPASS`` with a suitable password.
|
|
|
|
.. only:: rdo
|
|
|
|
3. Create the ``ceilometer`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
# mongo --host controller --eval '
|
|
db = db.getSiblingDB("ceilometer");

|
connecting to: controller:27017/test
|
|
Successfully added user: { "user" : "ceilometer", "roles" : [ "readWrite", "dbAdmin" ] }
|
|
|
|
Replace ``CEILOMETER_DBPASS`` with a suitable password.
|
|
|
|
|
|
4. Source the ``admin`` credentials to gain access to admin-only
|
|
CLI commands:
|
|
|
|
.. code-block:: console
|
|
|
|
$ source admin-openrc.sh
|
|
|
|
5. To create the service credentials, complete these steps:
|
|
|
|
a. Create the ``ceilometer`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack user create --password-prompt ceilometer
|
|
User Password:

2. Generate a random value to use as the telemetry secret:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openssl rand -hex 10
|
|
|
|
3. Edit the :file:`/etc/ceilometer/ceilometer.conf` file and complete
|
|
the following actions:
|
|
|
|
a. In the ``[database]`` section, configure database access:
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
[database]
|
|
...
|
|
connection = mongodb://ceilometer:CEILOMETER_DBPASS@controller:27017/ceilometer
|
|
|
|
Replace ``CEILOMETER_DBPASS`` with the password you chose for the

|
Telemetry module database. You must escape special characters such
|
|
as ':', '/', '+', and '@' in the connection string in accordance
|
|
with RFC2396.
|
|
|
|
b. In the ``[DEFAULT]`` and ``[oslo_messaging_rabbit]`` sections,
|
|
configure ``RabbitMQ`` message queue access:

|
[oslo_messaging_rabbit]
|
|
...
|
|
rabbit_host = controller
|
|
rabbit_userid = openstack
|
|
rabbit_password = RABBIT_PASS
|
|
|
|
Replace ``RABBIT_PASS`` with the password you chose for the
|
|
``openstack`` account in ``RabbitMQ``.
|
|
|
|
c. In the ``[DEFAULT]`` and ``[keystone_authtoken]`` sections,
|
|
configure Identity service access:
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
[DEFAULT]
|
|
...
|
|
auth_strategy = keystone
|
|
|
|
[keystone_authtoken]
|
|
...
|
|
auth_uri = http://controller:5000/v2.0
|
|
identity_uri = http://controller:35357
|
|
admin_tenant_name = service
|
|
admin_user = ceilometer
|
|
admin_password = CEILOMETER_PASS
|
|
|
|
Replace ``CEILOMETER_PASS`` with the password you chose for
|
|
the ``ceilometer`` user in the Identity service.
|
|
|
|
.. note::
|
|
|
|
Comment out any ``auth_host``, ``auth_port``, and ``auth_protocol``
|
|
options because the ``identity_uri`` option replaces them.
|
|
|
|
d. In the ``[service_credentials]`` section, configure service credentials:
|
|
|
|
.. code-block:: ini
|
|
:linenos:

os_auth_url = http://controller:5000/v2.0
|
|
os_username = ceilometer
|
|
os_tenant_name = service
|
|
os_password = CEILOMETER_PASS
|
|
os_endpoint_type = internalURL
|
|
os_region_name = RegionOne
|
|
|
|
Replace ``CEILOMETER_PASS`` with the password you chose for
|
|
the ``ceilometer`` user in the Identity service.
|
|
|
|
e. In the ``[publisher]`` section, configure the telemetry secret:
|
|
|
|
.. code-block:: ini
|
|
:linenos:
|
|
|
|
[publisher]
|
|
...
|
|
telemetry_secret = TELEMETRY_SECRET
|
|
|
|
Replace TELEMETRY_SECRET with the telemetry secret
|
|
that you generated in a previous step.
|
|
|
|
.. only:: obs
|
|
|
|
f. In the ``[collector]`` section, configure the dispatcher:
