# Ansible Role: NTP [![Build Status](https://travis-ci.org/geerlingguy/ansible-role-ntp.svg?branch=master)](https://travis-ci.org/geerlingguy/ansible-role-ntp) Installs NTP on Linux. ## Requirements None. ## Role Variables Available variables are listed below, along with default values (see `defaults/main.yml`): ntp_enabled: true Whether to start the ntpd service and enable it at system boot. On many virtual machines that run inside a container (like OpenVZ or VirtualBox), it's recommended you don't run the NTP daemon, since the host itself should be set to synchronize time for all it's child VMs. ntp_timezone: Etc/UTC Set the timezone for your server. ntp_manage_config: false Set to true to allow this role to manage the NTP configuration file (`/etc/ntp.conf`). ntp_area: '' Set the [NTP Pool Area](http://support.ntp.org/bin/view/Servers/NTPPoolServers) to use. Defaults to none, which uses the worldwide pool. ntp_servers: - "0{{ ntp_area }}.pool.ntp.org iburst" - "1{{ ntp_area }}.pool.ntp.org iburst" - "2{{ ntp_area }}.pool.ntp.org iburst" - "3{{ ntp_area }}.pool.ntp.org iburst" Specify the NTP servers you'd like to use. Only takes effect if you allow this role to manage NTP's configuration, by setting `ntp_manage_config` to `true`. ntp_restrict: - "127.0.0.1" - "::1" Restrict NTP access to these hosts; loopback only, by default. ## Dependencies None. ## Example Playbook - hosts: all roles: - geerlingguy.ntp *Inside `vars/main.yml`*: ntp_timezone: America/Chicago ## License MIT / BSD ## Author Information This role was created in 2014 by [Jeff Geerling](http://www.jeffgeerling.com/), author of [Ansible for DevOps](https://www.ansiblefordevops.com/).
