Ansible時區模塊失敗（不同操作系統上的不同原因）

Question

我決定重構一些劇本並嘗試新的timezone module。

我嘗試的任務是在手冊中給出的例子的完整副本：

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

它未能每個系統我試了。結果流浪機器：

• 在Debian 8（debian/jessie64）：

  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） - 不同的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） - 與CentOS相同，與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": []}

我錯過了什麼嗎？是否需要某些依賴項？

Answer 1

timedatectl需要sudo特權。

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

Answer 2

檢查是否已安裝DBUS包（在Ubuntu上測試）：

dpkg -l dbus 

，並安裝它：

apt-get install -y dbus 

否則你會得到一個錯誤：

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