Notes

Basic Authentication

Basic authentication may be set up with

apt: pkg=apache2-utils
command: htpasswd -bc {{ grafana_nginx_http_auth_file }} username password

Self-Signed Certificate

You can create a self-signed certificate to use for SSL:

- command: openssl genrsa -out {{ grafana_nginx_ssl_key_path }} 2048 creates={{ grafana_nginx_ssl_key_path }}
- command: openssl req -new -key {{ grafana_nginx_ssl_key_path }} -out {{ grafana_nginx_ssl_csr_path }} -subj "/C={{ country_code }}/ST={{ state }}/L={{ location }}/O={{ organication }}/OU={{ organizational_unit }}/CN={{ cname }}" creates={{ grafana_nginx_ssl_csr_path }}
- command: openssl x509 -req -days 365 -in {{ grafana_nginx_ssl_csr_path }} -signkey {{ grafana_nginx_ssl_key_path }} -out {{ grafana_nginx_ssl_cert_path }} creates={{ grafana_nginx_ssl_cert_path }}

Listen Address

The default installation only listens on 127.0.0.1, so is not externally accessible. To make your server publicly accessible, set grafana_nginx_listen to 0.0.0.0. If you do this, it's strongly recommended that you also set grafana_nginx_enable_ssl and grafana_nginx_http_auth_file to password protect the site and ensure that the password is not sent in the clear.
