我创建了Ansible剧本来配置: -数据库服务器 -Nginx和php服务器
数据库服务器需要知道php服务器的IP地址以配置数据库访问权限。 Web服务器需要知道数据库服务器的IP地址,以配置网站的数据库访问权限。 我尝试了proxy_facts:
vars:
Database_server_name: "SVWEB-03"
Web_server_name: "SVWEB-02"
- name: Web server ip address
set_fact:
Web_server_ip: "{{ ansible_default_ipv4.address }}"
delegate_to: "{{ Web_server_name }}"
delegate_facts: True
when:
- "Database_server_name in inventory_hostname"
- name: Database server ip address
set_fact:
Database_server_ip: "{{ ansible_default_ipv4.address }}"
delegate_to: "{{ Database_server_name }}"
delegate_facts: True
when:
- "Web_server_name in inventory_hostname"
- debug:
msg: "{{ Web_server_ip }}"
when:
- "Database_server_name in inventory_hostname"
- debug:
msg: "{{ Database_server_ip }}"
when:
- "Web_server_name in inventory_hostname"
但是我有错误:

请问有人知道我的错误吗?
答案 0 :(得分:0)
我相信您需要的是hostvars
:
- name: Database server ip address
set_fact:
Database_server_ip: "{{ hostvars.Database_server_name.ansible_default_ipv4.address }}"
