icinga: Step by Step installing Icinga Director in ubuntu

Installing Icinga Director on an Ubuntu system involves several steps, primarily focused on ensuring that your system meets the prerequisites, installing Icinga Director, and integrating it with Icinga 2 and Icinga Web 2. Here’s a step-by-step guide to help you through the process:

Prerequisites

1. Icinga 2: Ensure Icinga 2 is installed and running on your Ubuntu system.
2. Icinga Web 2: Ensure Icinga Web 2 is installed and operational as Icinga Director is a module for Icinga Web 2.
3. Database: Icinga Director requires a database. MySQL or MariaDB is recommended. Ensure that the database service is installed and running.

Step 1: Install Required Packages

First, you need to install PHP and other necessary packages that Icinga Director depends on:

sudo apt update
sudo apt install php php-cli php-gd php-xml php-bcmath php-mbstring php-json php-curl php-zip git

Step 2: Download Icinga Director

You can clone the Icinga Director from its GitHub repository. It’s advisable to get the latest stable version:

REFERENCE – https://icinga.com/docs/icinga-director/latest/doc/02-Installation/Ubuntu/

cd /usr/share/icingaweb2/modules
sudo git clone https://github.com/Icinga/icingaweb2-module-director.git director
sudo git checkout $(git describe --tags `git rev-list --tags --max-count=1`)
Code language: JavaScript (javascript)

Step 3: Set up Permissions

Ensure the web server user (usually www-data on Ubuntu) owns the Icinga Web 2 modules directory:

sudo chown -R www-data:www-data /usr/share/icingaweb2/modules/director

Step 4: Prepare the Database

Create a database and user for Icinga Director:

sudo mysql -u root -p

CREATE DATABASE director;
GRANT ALL PRIVILEGES ON director.* TO 'director'@'localhost' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
EXIT;
Code language: PHP (php)

Step 5: Enable the Icinga Director Module

Enable the module in Icinga Web 2 by creating the configuration file:

sudo icingacli module enable director
Code language: JavaScript (javascript)

Step 6: Configure Icinga Director

Log into your Icinga Web 2 interface. Go to the Configuration tab, then Modules, and select Director. You will need to click on “Create Schema” and then add the database resource you created.

Step 7: Run the Kickstart Wizard

The Icinga Director provides a Kickstart Wizard to automate the initial setup. Run the Kickstart Wizard from the Icinga Web 2 interface under the Director module settings. You’ll need to provide the Icinga 2 API credentials and the database details you set up earlier.

Step 8: Check Icinga Director Functionality

After completing the setup, navigate through the Director module in Icinga Web 2 to ensure it’s functioning correctly. Begin configuring hosts, services, and check commands as required.

Configure Director

Before doing anything lets configure Director, we will need to add the director database as a new resource and run it wizard.

1. Create a new resource for the Icinga Director database via the Configuration → Application → Resources menu. Please make sure that you configure utf8 as encoding.
2. Select Icinga Director directly from the main menu and you will be taken to the kickstart wizard. Follow the instructions and you are done!

Now you can enable the Director by choosing this new resource as a target. You will then be asked to create the schema.

After schema has been created you will find multiple deployments pending that need to be pushed to the database.

Click on Deploy and that’s it! The system is installed and ready for action.
