Ansible - 错误!字段 'hosts' 是必需的，但未设置

Question

启动剧本时出现错误，但我不知道原因......

ERROR! the field 'hosts' is required but was not set

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

还有我的/etc/ansible/hosts :

[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" }

请帮帮我:)问候，

您的剧本中有语法错误。

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