Ildiko Vancsa b33f32b714 Add install-guide for ceilometer
This adds ceilometer-specific contents of the OpenStack Installation Guide
in the ceilometer repo per [1]. A separate change will remove the
ceilometer contents from the OpenStack Installation Guide for Newton per [2].

The ceilometer install-guide structure is based on Install Guide
Cookiecutter [3].

Also adds tox.ini environment for install-guide and adds
openstackdocs-theme to test-requirements.txt.

NoSQL database for Red Hat Enterprise Linux and CentOS

The Telemetry service uses a NoSQL database to store information. The database typically runs on the controller node. The procedures in this guide use MongoDB.

Install and configure components

  1. Install the MongoDB packages:

    # yum install mongodb-server mongodb
  2. Edit the /etc/mongod.conf file and complete the following actions:

    • Configure the bind_ip key to use the management interface IP address of the controller node.

      bind_ip = 10.0.0.11
    • By default, MongoDB creates several 1 GB journal files in the /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:

      smallfiles = true

      You can also disable journaling. For more information, see the MongoDB manual.

Finalize installation

  • Start the MongoDB service and configure it to start when the system boots:

    # systemctl enable mongod.service
    # systemctl start mongod.service
