Vagrant project for Drupal and the ELK stack
You will get two vagrant managed VMs out this repository. One running Drupal and the other running the ELK (Elasticsearch, Logstash, Kibana) stack. Things have been setup so that Drupal's logs are stored in Elasticsearch. These can be explored using Kibana which provides a web interface for the logs.
This Vagrant project has been created as an accessory to an [article about setting up the ELK stack for managing Drupal's log] (https://demo.codesetter.com/drupal-log-elasticsearch-logstash-kibana).
There are quite a few online tutorials and presentations on how to save and use Drupal's logs in Elasticsearch. But I have not found any online demo. This Vagrant project tries to fill in that gap. It is not an online demo of course, instead it will let you spin up two VMs running Drupal and the ELK stack. You can then find out how it feels like to play with Drupal's logs from inside Kibana's web interface. If you like it, you can then use the relevant configuration files to setup your own environment. If you do not like it, you can destroy the VMs and move on without losing much time :)
How to run
- Install Vagrant if necessary. This project has been developed using version 1.8.1.
- [Install Ansible] (http://docs.ansible.com/ansible/intro_installation.html). The playbooks have been tested in version 126.96.36.199.
- Issue "vagrant up" from the project directory. It can take up to an hour for both VMs to be ready and running for the first time. Total memory requirement is nearly 2GB.
- The hostnames of the VMs are drupal.dev (192.168.33.33) and elk.dev (192.168.33.35). You may have to add these to your operating system's hosts file before accessing them from a web browser.
- Once the VMs are up, login and logout of [Drupal] (http://drupal.dev/) as admin/admin. This should generate at least one log entry. The Drupal instance is using the "minimal" profile which makes it look quite bland. Let that not surprise you.
- Open Kibana from http://elk.dev:5601/. On the first visit, you will find yourself in Kibana's [index setup screen] (https://www.elastic.co/guide/en/kibana/current/tutorial-define-index.html). Once past this, [import] (https://www.elastic.co/guide/en/kibana/current/managing-saved-objects.html) the "Drupal" search filter from the "Settings > Objects > Import" tab. You will find the search filter file that needs importing as part of this repository at "the-ansible-files/conf/elk/kibana-drupal-search-export.json". Afterwards, the "Discovery" tab will let you [play] (https://www.elastic.co/guide/en/kibana/current/discover.html#load-search) with Drupal's logs.
Software versions in the VMs
- Operating system: Debian 8 (Jessie) for x86
- Drupal: 8.x
- Elasticsearch: 2.3
- Logstash: 2.3
- Kibana: 4.5
- Curator: 4.x
Notes on Ansible playbooks
The playbooks in this repository are very basic and are not at all production-grade. They are also specific to Debian. They may work in Ubuntu, but certainly not in Redhat derived distributions. Whatever the case, you can use them as a basis for writing your own playbooks. The nature of the playbook syntax means anyone can read them and figure out what is going on. That understanding along with the configuration files are the primary take-away from this repository.
