Installing Kilo on Ubuntu
*************************

Development Environment
+++++++++++++++++++++++

Installing Designate
====================

.. index::
   double: install; designate

1. Install system package dependencies (Ubuntu)

::

   $ apt-get update
   $ apt-get install python-pip python-virtualenv git
   $ apt-get build-dep python-lxml

2. Clone the Designate repo from GitHub

::

   $ mkdir openstack
   $ cd openstack
   $ git clone https://git.openstack.org/openstack/designate.git
   $ cd designate

3. Checkout a specific version (in this case, the Kilo release)

::

   $ git checkout stable/kilo

4. Setup a virtualenv

.. note::
   This is an optional step, but will allow Designate's dependencies
   to be installed in a contained environment that can be easily deleted
   if you choose to start over or uninstall Designate.

::

   $ virtualenv --no-site-packages .venv
   $ . .venv/bin/activate

5. Install Designate and its dependencies

.. note::
   If you run into the error: Installed distribution pbr 1.1.1 conflicts with requirement pbr>=0.6,!=0.7,<1.0, try doing pip install pbr==0.11.0

::

   $ pip install -r requirements.txt -r test-requirements.txt
   $ python setup.py develop

If you run into the error: "Installed distribution oslo.config 1.9.3 conflicts with requirement oslo.config>=1.11.0", add the following into requirements.txt then repeat step 5:

::

   python-keystoneclient>=1.1.0,<1.4.0
   pycadf>=0.8.0,<0.9.0

6. Change directories to the etc/designate folder.

.. note::
    Everything from here on out should take place in or below your designate/etc folder

::

   $ cd etc/designate


7. Create Designate's config files by copying the sample config files

::

   $ ls *.sample | while read f; do cp $f $(echo $f | sed "s/.sample$//g"); done


8. Make the directory for Designate’s log files

::

   $ mkdir -p ../../log


9. Make the directory for Designate’s state files

::

   $ mkdir -p ../../state



Configuring Designate
======================

.. index::
    double: configure; designate

Open the designate.conf file for editing

::

  $ editor designate.conf


Copy or mirror the configuration from this sample file here:

.. literalinclude:: ../examples/basic-config-sample-kilo.conf
    :language: ini


Installing RabbitMQ
===================

.. note::

    Do the following commands as "root" or via sudo <command>

Install the RabbitMQ package

::

    $ apt-get install rabbitmq-server

Create a user:

::

    $ rabbitmqctl add_user designate designate

Give the user access to the / vhost:

::

    $ sudo rabbitmqctl set_permissions -p "/" designate ".*" ".*" ".*"


Installing MySQL
================

.. index::
    double: install; mysql

Install the MySQL server package

::

    $ apt-get install mysql-server-5.5


If you do not have MySQL previously installed, you will be prompted to change the root password.
By default, the MySQL root password for Designate is "password". You can:

* Change the root password to "password"
* If you want your own password, edit the designate.conf file and change any instance of
   "mysql://root:password@127.0.0.1/designate" to "mysql://root:YOUR_PASSWORD@127.0.0.1/designate"

You can change your MySQL password anytime with the following command::

    $ mysqladmin -u root -p password NEW_PASSWORD
    Enter password <enter your old password>

Create the Designate tables

::

    $ mysql -u root -p
    Enter password: <enter your password here>

    mysql> CREATE DATABASE `designate` CHARACTER SET utf8 COLLATE utf8_general_ci;
    mysql> CREATE DATABASE `designate_pool_manager` CHARACTER SET utf8 COLLATE utf8_general_ci;
    mysql> exit;


Install additional packages

::

    $ apt-get install libmysqlclient-dev
    $ pip install mysql-python


Installing BIND9
================

.. index::
    double: install; bind9

Install the DNS server, BIND9

::

      $ apt-get install bind9

      # Update the BIND9 Configuration
      $ editor /etc/bind/named.conf.options

      # Change the corresponding lines in the config file:
      options {
        directory "/var/cache/bind";
        dnssec-validation auto;
        auth-nxdomain no; # conform to RFC1035
        listen-on-v6 { any; };
        allow-new-zones yes;
        request-ixfr no;
        recursion no;
      };

      # Disable AppArmor for BIND9
      $ touch /etc/apparmor.d/disable/usr.sbin.named
      $ service apparmor reload

      # Restart BIND9:
      $ service bind9 restart


Initialize & Start the Central Service
======================================

.. index::
   double: install; central


Sync the Designate database.

::

   $ designate-manage database sync

Start the central service.

::

   $ designate-central


You'll now be seeing the log from the central service.

Initialize & Start the API Service
==================================

.. index::
   double: install; api

Open up a new ssh window and log in to your server (or however you’re communicating with your server).

::

   $ cd openstack/designate

   # Make sure your virtualenv is sourced
   $ source .venv/bin/activate

   # Start the API Service
   $ designate-api

You’ll now be seeing the log from the API service.


Initialize & Start the Pool Manager Service
===========================================

.. index::
   double: install; pool-manager

Open up a new ssh window and log in to your server (or however you’re communicating with your server).

::

   # Sync the Pool Manager's cache:
   $ designate-manage pool-manager-cache sync

   # Start the pool manager service:
   $ designate-pool-manager


You'll now be seeing the log from the Pool Manager service.


Initialize & Start the MiniDNS Service
===========================================

.. index::
   double: install; minidns

Open up a new ssh window and log in to your server (or however you’re communicating with your server).

::

   # Start the minidns service:
   $ designate-mdns


You'll now be seeing the log from the MiniDNS service.

Exercising the API
==================

.. note:: If you have a firewall enabled, make sure to open port 53, as well as Designate's default port (9001).

Using a web browser, curl statement, or a REST client, calls can be made to the
Designate API using the following format where "api_version" is either v1 or v2
and "command" is any of the commands listed under the corresponding version at :ref:`rest`

::

   http://IP.Address:9001/api_version/command

You can find the IP Address of your server by running

::

   curl -s checkip.dyndns.org | sed -e 's/.*Current IP Address: //' -e 's/<.*$//'

A couple of notes on the API:

- Before Domains are created, you must create a server (/v1/servers).
