How to Install Designate on Arch Linux

Designate is a DNS service provided by OpenStack that allows you to manage DNS data and automate DNS operations. In this tutorial, we will explain how to install Designate on Arch Linux.

Prerequisites

Before you start, ensure that:

You have a non-root user with sudo privileges
Your system is up-to-date

Step 1: Install Required Dependencies

Designate requires some dependencies to function correctly. For Arch Linux, you can install the required dependencies by running the following command:

sudo pacman -S python-pip python-virtualenv python-setuptools mysql

Step 2: Install Designate

Now, we need to install Designate:

First, we need to create a virtual environment for Designate.
```
virtualenv --system-site-packages /opt/designate
```
This will create a virtual environment in the /opt/designate directory.
Next, we need to activate the virtual environment:
```
source /opt/designate/bin/activate
```
After this command, your prompt should indicate that you are using the designate virtual environment.
Now, we can install Designate:
```
pip install designate
```
This command will install Designate and its dependencies into the virtual environment.

Step 3: Configure Designate

We need to create a MySQL database for Designate.
```
mysql -u root -p
```
This command will prompt you for your MySQL root password.

Once you are in the MySQL shell, create a Designate database and user:

CREATE DATABASE designate;
CREATE USER 'designate'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON designate.* TO 'designate'@'localhost';

Replace password with a strong password of your choice.

Next, we need to configure Designate. Copy the sample configuration file:
```
sudo cp /opt/designate/local.conf.sample /opt/designate/local.conf
```
Edit the configuration file using your favorite text editor:
```
sudo nano /opt/designate/local.conf
```
Replace the [service:database] section with the following:
```
[service:database]
backend_url = mysql://designate:password@localhost/designate
```
Replace password with the password you set for the MySQL designate user.
Save and close the configuration file.

Step 4: Create the Designate Databases

Now, we need to create the Designate databases:

designate-manage database sync

This command will create the necessary Designate database tables.

Step 5: Start the Designate Services

Finally, we need to start the Designate services:

designate-central &
designate-api &
designate-mdns &

These commands will start the Designate central, API, and mDNS services.

Conclusion

You have successfully installed Designate on Arch Linux. Now, you can use it to manage your DNS data and automate your DNS operations.
