Creates an Amazon AWS Cluster using using CloudFormation template and Ansible to provision ELK stack on Ubuntu 14.04 Trusty

REQUIREMENTS:

  • Python 2.7.x
  • Ansible
  • AWS CLI tools
  • Python Boto is setup and configured to use the AWS keys. the ~/.boto file contains aws_access_key and aws_secret_key
  • A Valid AWS KeyFile and added to the proper security role. The .pem file should loaded into the ROOT folder of the project

CREATE INSTANCE using a CloudFormation Template:

Create an AWS stack using command line (preferred method)

aws cloudformation create-stack --stack-name ansible-elk --template-body file://files/cloudformation-ansible.json --parameters ParameterKey=KeyName,ParameterValue={Personal VALID AWS KeyName} ParameterKey=DiskType,ParameterValue=ephemeral ParameterKey=InstanceType,ParameterValue=t1.micro ParameterKey=ClusterSize,ParameterValue=1 --capabilities CAPABILITY_IAM

ex.) testweb is the keypair that is permissioned for my account and should be accessible (my testweb.pem file is located in same directory) aws cloudformation create-stack --stack-name ansible-elk --template-body file://files/cloudformation-ansible.json --parameters ParameterKey=KeyName,ParameterValue=testweb ParameterKey=DiskType,ParameterValue=ephemeral ParameterKey=InstanceType,ParameterValue=t1.micro ParameterKey=ClusterSize,ParameterValue=1 --capabilities CAPABILITY_IAM

DELETE INSTANCE :

Delete an AWS stack using command line (preferred method)

aws cloudformation delete-stack --stack-name ansible-elk

PROVISION INSTANCE ELK Stack using ansible:

Provision the stack using ansible playbook using ec2.py Inventory script

(requires boto installation and setup using valid aws credentials from the control machine) (preferred method) ansible-playbook -i plugins/ec2.py --private-key={Personal VALID AWS KeyName}.pem provision_stack.yml

ex.) ansible-playbook -i plugins/ec2.py --private-key=testweb.pem provision_stack.yml

OR Provision the stack using ansible playbook using a "hosts" file - Must manually put the created hosts name in the launched category

ansible-playbook -i hosts provision_stack.yml

Connect to Kibana on port 80 of newly create AWS instance using the follwoing credentials

  • username: kibanaadmin
  • password: test123

Forward logs on port 5000 and use valid security cert

NSTRUCTIONS TO CREATE a new valid certificate to be used with logstash on server

To create a new cert on the logstash server - used for forwarder secure connection

sudo vi /etc/ssl/openssl.cnf

Find the [ v3_ca ] section in the file, and add this line under it (substituting in the Logstash Server's private IP address):

subjectAltName = IP: <logstash_server_private_ip> c mple/etc/pki/tls sudo openssl req -config /etc/ssl/openssl.cnf -x509 -days 3650 -batch -nodes -newkey rsa:2048 -keyout logstash-forwarder-example.key -out logstash-forwarder-example.crt

Copy the new crt file to the forwarder
