Graylog role

Ansible role to install and setup Graylog 2 server. Also installs dependencies such as ElasticSearch and MongoDB.

Uses Mediafellows' ElasticSearch role to install ElasticSearch.

Requirements

Server running Ubuntu Linux, or other debiand based distro.

Role Variables

Those variables have to be set for thing to work:

• graylog_password_salt: abc123123123 - Set your own PW salt for Graylog PWs/seccrets
• graylog_root_username: graylog - Set your own dmin username for Graylog login
• graylog_root_password_sha2: asdccsd3123 - Set your own admin PW for Graylog login
• graylog_public_api_endpoint: 'https://my-dummy-domin.com:9000/api/' - Set this to the publicly reachable API endpoint
• elasticsearch_heap_size: 2g - Set this to half the amount of the instaces RAM size. If this value is to high Elasticsearch might fail to start (runing out of Memory)!

Those variables can be overriden optionally (come with acceptable defaults):

• elasticsearch_cluster_name: graylog - Change to your prefered ES cluster name
• graylog_root_user_email: [email protected] - Set admin users email
• graylog_major_version: 2.3 - Major graylog version to install
• elasticsearch_version: 2.3.3 - ElasticSearch version to install (make sure it's compatible with the Graylog version).
• graylog_custom_plugins: [] - List of Graylog plugins to install (in addition to default ones)
• elasticsearch_plugins: [] - List of ElasticSearch plugins to install

Dependencies

Depends on the ElasticSearch Ansible role mediafellows.elasticsearch. Make sure that role installed in your Ansible project first.
