找错了！字段“主机”是必需的，但没有设置

Question

当我发布一本剧本时我犯了一个错误，但我找不到为什么.

错误！字段“主机”是必需的，但没有设置

这是我的main.yml：

---
- hosts: hosts
- vars: 
  - elasticsearch_java_home: /usr/lib/jmv/jre-1.7.0
  - elasticsearch_http_port: 8443

- tasks: 
  - include: tasks/main.yml

- handlers:
  - include: handlers/main.yml

和我的/etc/ansible/主机：

[hosts]
10.23.108.182
10.23.108.183
10.23.108.184
10.23.108.185

当我测试ping时，一切都很好：

[root@poste08-08-00 elasticsearch]# ansible hosts -m ping
10.23.108.183 | SUCCESS => {
    "changed": false, 
    "ping": "pong" }
10.23.108.182 | SUCCESS => {
    "changed": false, 
    "ping": "pong" }
10.23.108.185 | SUCCESS => {
    "changed": false, 
    "ping": "pong" }
10.23.108.184 | SUCCESS => {
    "changed": false, 
    "ping": "pong" }

请帮助我:)问候，

Answer 1

您的剧本中有语法错误。

---
- hosts: webservers
  vars:
    http_port: 80
    max_clients: 200

请参阅：intro.html

Answer 2

---
- hosts: all

  remote_user: root

  tasks:

Answer 3

任务前删除连字符，因为这是单曲的一部分：

---
hosts: hosts
- vars: 
  - elasticsearch_java_home: /usr/lib/jmv/jre-1.7.0
  - elasticsearch_http_port: 8443

- tasks: 
  - include: tasks/main.yml

- handlers:
  - include: handlers/main.yml

根据YAML规范

块序列用破折号(“-”)表示每个成员。块映射使用冒号标记每个(key: value)对。
