我正在尝试提供EC2实例并使用来自localhost的Ansible在其上安装LAMP服务器 . 我已成功配置该实例，但由于此错误“无法通过ssh连接到主机”，我无法安装apache，php和mysql .
操作系统：El Capitan 10.11.6
Ansible：2.0.2.0
这是剧本：`---
- hosts: localhost
connection: local
gather_facts: no
vars_files:
- "vars/{{ project_name }}.yml"
- "vars/vpc_info.yml"
tasks:
- name: Provision
local_action:
module: ec2
region: "xxxxxx"
vpc_subnet_id: "xxxxxx"
assign_public_ip: yes
key_name: "xxxxxxx"
instance_type: "t2.nano"
image: "xxxxxxxx"
wait: yes
instance_tags:
Name: "LAMP"
class: "test"
environment: "dev"
project: "{{ project_name }}"
az: a
exact_count: 1
count_tag:
Name: "LAMP"
monitoring: yes
register: ec2a
- hosts: lamp
roles:
- lamp_server
ansible.cfg文件的内容：
[defaults]
private_key_file=/Users/nico/.ssh/xxxxx.pem
库存：
lamp ansible_ssh_host=<EC2 IP> ansible_user=ubuntu
用于运行playbook的命令：
ansible-playbook -i inventory ec2_up.yml -e project_name="lamp_server" -vvvv
输出：

我已经阅读了很多有关此错误的主题，但没有任何帮助 . :(
