Ansible IP地址变量远程主机

Question

我有以下问题：

我正在编写用于配置 NFS 服务器和 NFS 客户端的剧本。

在同一个剧本中，我还包括了 2 个其他任务：

CentOS_7_NFS_Server.yml 和 CentOS_7_NFS_Client.yml

因为我可以执行我需要比较

的 IP 地址的任务之一

远程主机

示例：

- include: CentOS_7_NFS_Server.yml
  when: ansible_all_ipv4_addresses == NFS_Server

- include: CentOS_7_NFS_Client.yml
  when:  ansible_all_ipv4_addresses == NFS_Client

在变量中：

NFS_Server: x.x.x.x
NFS_Client : y.y.y.y

我遇到了这个错误

FAILED! => {"msg": "The conditional check 'ansible_all_ipv4.address 
== NFS_Client' failed. The error was: error while evaluating 
conditional (ansible_all_ipv4.address == NFS_Client): 
'ansible_all_ipv4' is undefined\n\nThe error appears to have been 
in

Answer 1

很可能 facts 的收集被禁用了。当您看到错误时：

ansible_all_ipv4_addresses: VARIABLE IS NOT DEFINED!

启用它

- hosts: nfs_server_and_client
  gather_facts: yes

还有一个问题。 ansible_all_ipv4_addresses 是 list 个 all 个地址。例如。

  ansible_all_ipv4_addresses:
  - 192.168.122.1
  - 10.1.0.11
  - 192.168.1.10

您必须选择一个或多个并将其分配给 NFS_Server 和 NFS_Client .那么条件应该是test if NFS_Server和NFS_Client分别在列表ansible_all_ipv4_addresses.

- include: CentOS_7_NFS_Server.yml
  when: NFS_Server in ansible_all_ipv4_addresses

- include: CentOS_7_NFS_Client.yml
  when: NFS_Client in ansible_all_ipv4_addresses
