Install and configure for Ubuntu
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This section describes how to install and configure the
Telemetry service, code-named ceilometer, on the controller node.
This section assumes that you already have a working OpenStack
environment with at least the following components installed:
Compute, Image Service, Identity.
Prerequisites
-------------
Before you install and configure the Telemetry service, you must
create a database, service credentials, and API endpoints. However,
unlike other services, the Telemetry service uses a NoSQL database.
See :ref:`environment-nosql-database-ubuntu` to install and configure
MongoDB before proceeding further.
1. 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
{
"user" : "ceilometer",
"pwd" : "72f25aeee7ad4be52437d7cd3fc60f6f",
"roles" : [
"readWrite",
"dbAdmin"
],
"_id" : ObjectId("5489c22270d7fad1ba631dc3")
}
Replace ``CEILOMETER_DBPASS`` with a suitable password.
.. note::
If the command fails saying you are not authorized to insert a user,
you may need to temporarily comment out the ``auth`` option in
the ``/etc/mongodb.conf`` file, restart the MongoDB service using
``service mongodb restart``, and try calling the command again.

Install and configure components
--------------------------------
#. Install the packages:
.. code-block:: console
# apt-get install ceilometer-api ceilometer-collector \
ceilometer-agent-central ceilometer-agent-notification \
python-ceilometerclient
.. include:: install-base-config-common.rst
Configure the Apache HTTP server
--------------------------------
#. Create the ``/etc/apache2/sites-available/wsgi-ceilometer.conf`` file
with the following content:
.. code-block:: apache
Listen 8777
<VirtualHost *:8777>
WSGIDaemonProcess ceilometer-api processes=2 threads=10 user=ceilometer group=ceilometer display-name=%{GROUP}
WSGIProcessGroup ceilometer-api
WSGIScriptAlias / "/var/www/cgi-bin/ceilometer/app"
WSGIApplicationGroup %{GLOBAL}
ErrorLog /var/log/apache2/ceilometer_error.log
CustomLog /var/log/apache2/ceilometer_access.log combined
</VirtualHost>
WSGISocketPrefix /var/run/apache2
#. Enable the Telemetry service virtual hosts:
.. code-block:: console
# a2ensite ceilometer
Finalize installation
---------------------
#. Reload the Apache HTTP server:
.. code-block:: console
# service apache2 reload
#. Restart the Telemetry services:
.. code-block:: console
# service ceilometer-agent-central restart
# service ceilometer-agent-notification restart
# service ceilometer-collector restart
