Ansible 时区模块失败（不同操作系统上的不同原因）

Question

我决定重构一些剧本并尝试新的 timezone module。

我尝试的任务是手册页中给出的示例的逐字副本：

- name: set timezone to Asia/Tokyo
  timezone:
    name: Asia/Tokyo

它在我尝试过的每个系统上都失败了。 Vagrant 机器的结果：

在 Debian 8 (debian/jessie64) 上：

TASK [set timezone to Asia/Tokyo] **********************************************
fatal: [debian]: FAILED! => {"changed": false, "cmd": "/usr/bin/timedatectl set-timezone Asia/Tokyo", "failed": true, "msg": "Failed to set time zone: The name org.freedesktop.PolicyKit1 was not provided by any .service files", "rc": 1, "stderr": "Failed to set time zone: The name org.freedesktop.PolicyKit1 was not provided by any .service files\n", "stdout": "", "stdout_lines": []}
在 CentOS 7 (centos/7) 上 - 不同于 Debian：

TASK [set timezone to Asia/Tokyo] **********************************************
fatal: [centos]: FAILED! => {"changed": false, "cmd": "/usr/bin/timedatectl set-timezone Asia/Tokyo", "failed": true, "msg": "Failed to set time zone: Interactive authentication required.", "rc": 1, "stderr": "Failed to set time zone: Interactive authentication required.\n", "stdout": "", "stdout_lines": []}
在 Ubuntu 16.04 (ubuntu/xenial64) - 与 CentOS 相同，与 Debian 不同：

TASK [set timezone to Asia/Tokyo] **********************************************
fatal: [ubuntu]: FAILED! => {"changed": false, "cmd": "/usr/bin/timedatectl set-timezone Asia/Tokyo", "failed": true, "msg": "Failed to set time zone: Interactive authentication required.", "rc": 1, "stderr": "Failed to set time zone: Interactive authentication required.\n", "stdout": "", "stdout_lines": []}

我错过了什么吗？是否需要一些依赖性？

Answer 1

timedatectl 需要 sudo 权限。

- name: set timezone to Asia/Tokyo
  timezone:
    name: Asia/Tokyo
  become: yes
  become_method: sudo

Answer 2

检查是否安装了 dbus 包（在 Ubuntu 上测试）：

dpkg -l dbus

并安装：

apt-get install -y dbus

否则会出现错误：

# /usr/bin/timedatectl
Failed to create bus connection: No such file or directory
