Installing Kilo on Ubuntu¶
Development Environment¶
Installing Designate¶
- Install system package dependencies (Ubuntu)
$ apt-get update
$ apt-get install python-pip python-virtualenv git
$ apt-get build-dep python-lxml
- Clone the Designate repo from GitHub
$ mkdir openstack
$ cd openstack
$ git clone https://git.openstack.org/openstack/designate.git
$ cd designate
- Checkout a specific version (in this case, the Kilo release)
$ git checkout stable/kilo
- 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
- 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
- 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
- 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
- Make the directory for Designate’s log files
$ mkdir -p ../../log
- Make the directory for Designate’s state files
$ mkdir -p ../../state
Configuring Designate¶
Open the designate.conf file for editing
$ editor designate.conf
Copy or mirror the configuration from this sample file here:

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¶
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¶
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¶
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¶
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¶
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¶
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 REST API Documentation
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).
