Install and configure for Red Hat Enterprise Linux and CentOS

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This section describes how to install and configure the
|
|
Telemetry service, code-named ceilometer, on the controller node.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
Before you install and configure the Telemetry service, you must
|
|
configure a target to send metering data to. The recommended endpoint
|
|
is Gnocchi_.
|
|
|
|
.. _Gnocchi: https://gnocchi.osci.io
|
|
.. include:: install-base-prereq-common.inc
|
|
|
|
Install Gnocchi
|
|
---------------
|
|
|
|
#. Install the Gnocchi packages. Alternatively, Gnocchi can be install using
|
|
pip:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install openstack-gnocchi-api openstack-gnocchi-metricd \
|
|
python-gnocchiclient
|
|
|
|
.. note::
|
|
|
|
Depending on your environment size, consider installing Gnocchi
|
|
separately as it makes extensive use of the cpu.
|
|
|
|
#. Install the uWSGI packages. The following method uses operating system
|
|
provided packages. Another alternative would be to use pip(or pip3,
|
|
depending on the distribution); using pip is not described in this doc:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install uwsgi-plugin-common uwsgi-plugin-python3 uwsgi
|
|
|
|
.. note::
|
|
|
|
Since the provided gnocchi-api wraps around uwsgi, you need to
|
|
make sure that uWSGI is installed if you want to use gnocchi-api
|
|
to run Gnocchi API.
|
|
As Gnocchi API tier runs using WSGI, it can also alternatively
|
|
be run using Apache httpd and mod_wsgi, or any other HTTP daemon.
|
|
|
|
.. include:: install-gnocchi.inc
|
|
|
|
Finalize Gnocchi installation
|
|
-----------------------------
|
|
|
|
#. Start the Gnocchi services and configure them to start when the
|
|
system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable openstack-gnocchi-api.service \
|
|
openstack-gnocchi-metricd.service
|
|
# systemctl start openstack-gnocchi-api.service \
|
|
openstack-gnocchi-metricd.service
|
|
|
|
Install and configure components
|
|
--------------------------------
|
|
|
|
#. Install the Ceilometer packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install openstack-ceilometer-notification \
|
|
openstack-ceilometer-central
|
|
|
|
.. include:: install-base-config-common.inc
|
|
|
|
Finalize installation
|
|
---------------------
|
|
|
|
#. Start the Telemetry services and configure them to start when the
|
|
system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable openstack-ceilometer-notification.service \
|
|
openstack-ceilometer-central.service
|
|
# systemctl start openstack-ceilometer-notification.service \
|
|
openstack-ceilometer-central.service
