可靠的主机名模块,根据IP地址设置主机名

hostname raspberry-pi ansible

Nicolas CASAUX · 技术社区 · 1 年前

我正在尝试使用 ansible hostname module 以更改多个Raspberry Pi计算模块4的主机名。因为它们都基于同一个Raspberry Pi操作系统映像,所以它们的主机名是 raspberrypi 对于他们所有人来说,我想改变的是什么。

我的库存大致如下:

rpi-cm4-1:
  node_number: 1
  name: rpi-cm4-1
  ansible_host: 192.168.1.101

rpi-cm4-2:
  node_number: 2
  name: rpi-cm4-2
  ansible_host: 192.168.1.102

...

我的剧本是这样的:

- name: Change hostname of managed nodes
  hosts: rpi_cm4-2
  tasks:
    - name: Change hostname of managed nodes
      ansible.builtin.hostname:
        name: "{{ hostvars[inventory_hostname].name }}"

当我运行剧本时,我面临的错误是:

TASK [Gathering Facts] *****************************************************************************************************
ok: [rpi-cm4-2]

TASK [Change hostname of managed nodes] *****************************************************************************************************
fatal: [rpi-cm4-2]: FAILED! => changed=false
  msg: |-
    Command failed rc=1, out=, err=Could not set pretty hostname: Connection timed out

我猜测 Ansible可能没有使用库存的ip地址(但它使用它来收集事实)。我该怎么做才能让他使用库存的IP?

我无法使Ansible使用IP地址。

这个 -vvv 实际上显示了这一点:

所以IP似乎被使用了。。。

很明显,它使用的是ip地址,所以这不是问题所在。看起来很容易是连接成功,但在尝试设置系统主机名时收到错误。

从错误消息来看,这看起来像是权限问题:

==== AUTHENTICATING FOR org.freedesktop.hostname1.set-static-hostname ====
Authentication is required to set the statically configured local hostname, as well as the pretty hostname.
Authenticating as: ,,, (pi)
Password: polkit-agent-helper-1: pam_authenticate failed: Authentication failure

您可能需要确保您以 root 在远程主机上:

- name: Change hostname of managed nodes
  hosts: rpi_cm4-2
  become: true
  tasks:
    - name: Change hostname of managed nodes
      ansible.builtin.hostname:
        name: "{{ hostvars[inventory_hostname].name }}"

注意添加的 become: true ,这将导致此播放中的所有任务以 根 .
