Ansible Vagrant profile for ELK (Elasticsearch, Logstash, Kibana)

This project builds a two-server ELK stack using Elasticsearch, Logstash, Kibana, and Filebeat to ship, store, and expose logs.

The first server (logs) has the entire ELK stack running, and pushes local auth.log entries into Elasticsearch via Filebeat and Logstash. The second server (web) runs an Nginx webserver and pushes the webserver access.log file and the server's auth.log entries into Elasticsearch via the logs server's Logstash instance.

Logs are transmitted securely using a self-signed certificate (see the elk-example certificate).

Building the VMs

  1. Download and install VirtualBox.
  2. Download and install Vagrant.
  3. [Mac/Linux only] Install Ansible.
  4. Run ansible-galaxy install -r requirements.yml in this directory to get the required Ansible roles.
  5. Run vagrant up to build the VMs.

Once the VMs are up and running (after vagrant up is complete and you're back at the command prompt), you can log into either one via SSH if you'd like by typing in vagrant ssh [name] (either logs for the ELK server, or web for the Nginx web server). Otherwise, the next steps are below.

Setting up your hosts file

You need to modify your host machine's hosts file (Mac/Linux: /etc/hosts; Windows: %systemroot%\system32\drivers\etc\hosts), adding the lines below:

192.168.56.90  logs.test
192.168.56.91  web.test

(Where logs.test/web.test is the hostname you have configured in the Vagrantfile).

After that is configured, you could visit http://logs.test/ in a browser, and you'll see the Kibana dashboard, and you can visit http://web.test/, and you'll see Nginx's default index page.

If you'd like additional assistance editing your hosts file, please read How do I modify my hosts file? from Rackspace.
