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
