These roles assume that you run ubuntu14.04. I used AWS for my tests

How to use these roles?

There is a separate role for each service you want to install and play around with.

Normally, the order of the steps you should take would be like this:

1. Install Storage and Log Indexer (Elastic Stack, Graylog):

   There is a role and a playbook for each storage+indexer host: elk, graylog.

2. (optional) Install a Message Broker on a separate host:

   There is a role for each Message Brokers to install: kafka, redis. Change broker.yml playbook to define which one you want to install.

3. Install some service (nginx, apache2, etc) on a separate host along with a shipper.

   There is a role for each log shipper and a role for services which installs services we specify in install_services variable inside log-generator.yml playbook. In the same playbook, we specify which log shipper we want to install. Note, that some roles, like filebeat, require a few variables to be set before running, so please see a role's readme file first before running anything.

Things you have to chagne

You'll have to change ansible.cfg file and make sure you have a correct path to the ssh key:

private_key_file = ~/.ssh/express42

Also, change hosts ip addresses inside the hosts file.

elk ansible_host=<public_ip_address> ansible_user=ubuntu

List the playbook you want to run in site.yml file.

How to run?

You can use a command like the one bellow to run all the playbooks you specified inside site.yml:

ansible-playbook site.yml

to run just one specific playbook, you can use this command:

ansible-playbook playbook/<name_of_playbook>
