ntp_timezone: 'Australia/Melbourne'
ntp_servers:
- '0.au.pool.ntp.org'
- '1.au.pool.ntp.org'
- '2.au.pool.ntp.org'
- '3.au.pool.ntp.org'
- 'ntp.ubuntu.com'
Available variables are listed below, along with default values (see defaults/main.yml):
ntp_timezone: 'UTC'
The timezone you want to configure. Valid values are based on the tz (timezone) database used by Linux and other Unix systems. See this page to find a timezone for your region.
ntp_packages:
A list of the NTP packages to install. Each package supports all parameters from the apt or yum modules. If the value remains omitted, the following packages will be installed by default.
| Debian/Ubuntu | RedHat/CentOS |
|---|---|
| ntp | ntp |
| tzdata | tzdata |
ntp_service_name:
The name of the daemon under which NTP runs. Typically this can be omitted since it's automatically determined
based on the target operating system. For RedHat/CentOS this is ntpd and Debian/Ubuntu it's ntp.
ntp_service_state: 'started'
The desired NTP service state, valid values are started, stopped, restarted or reloaded.
ntp_service_enabled: yes
Whether the NTP service should start on boot, valid values are yes, or no.
ntp_conf_template: 'ntp.j2'
The NTP configuration template file processed by the Jinja2 templating language. Most variables within this role are consumed by this template, if for some reason you need to offer more settings than this template provides, you can override this value with a template of your choice.
ntp_drift_file: '/var/lib/ntp/ntp.drift'
The name and path of the drift file. This file stores the frequency offset between the system clock running at its nominal frequency and the frequency required to remain in synchronization with UTC.
ntp_statistics_dir:
The path statistics get outputted to. If the value is left undefined no statistics will be generated.
ntp_statistics: 'loopstats peerstats clockstats'
The statistic types to monitor. There are 6 supported types available:
clockstats, cryptostats, loopstats, peerstats, rawstats, and sysstats.
ntp_file_generation_sets:
- 'filegen loopstats file loopstats type day enable'
- 'filegen peerstats file peerstats type day enable'
- 'filegen clockstats file clockstats type day enable'
The file generation sets provide a means for handling files that are continuously growing during the lifetime of a server. Server statistics are a typical example for such files. Generation file sets provide access to a set of files used to store the actual data.
ntp_servers:
- '0.ubuntu.pool.ntp.org'
- '1.ubuntu.pool.ntp.org'
- '2.ubuntu.pool.ntp.org'
- '3.ubuntu.pool.ntp.org'
- 'ntp.ubuntu.com'
The servers that will be used to synchronize the local time. In client mode the client clock can synchronize to the remote server or local reference clock, but the remote server can never be synchronized to the client clock. See this page to find servers in your region.
ntp_restrictions:
- 'restrict -4 default kod notrap nomodify nopeer noquery'
- 'restrict -6 default kod notrap nomodify nopeer noquery'
- 'restrict 127.0.0.1'
- 'restrict ::1'
The restrictions are used to control access to NTP. By default, time is exchanged with everybody, while preventing them from adjusting the configuration. Local users may interrogate the NTP server more closely.
