Ansible AWS:无法连接到 EC2 实例 [英] Ansible AWS: Unable to connect to EC2 instance
问题描述
我想使用一个 Ansible playbook 创建一个安装了 LAMP 堆栈的 EC2 实例.
I want to create an EC2 instance with LAMP stack installed using one Ansible playbook.
实例创建工作正常,我可以在 EC2 控制台中修改它,但是在尝试访问实例时出现问题,例如安装 apache 或创建密钥.
The instance creation works fine, and I can modify it in the EC2 Console, but the problem appears when trying to access the instance for example install apache or create keys.
这是错误:
致命:[35.154.26.86]:无法访问!=> {改变":假,"msg": "[Errno None] 无法连接到端口 22 或 35.154.26.86",无法访问":true}
fatal: [35.154.26.86]: UNREACHABLE! => { "changed": false, "msg": "[Errno None] Unable to connect to port 22 on or 35.154.26.86", "unreachable": true }
这是我的剧本:
---
- name: Power up an ec2 with LAMP stack installed
hosts: localhost
become: true
become_user: root
gather_facts: False
vars:
keypair: myKeyPair
security_group: launch-wizard-1
instance_type: t2.micro
image: ami-47205e28
region: x-x-x
tasks:
- name: Adding Python-pip
apt: name=python-pip state=latest
- name: Install Boto Library
pip: name=boto
- name: Launch instance (Amazon Linux)
ec2:
key_name: "{{ keypair }}"
group: "{{ security_group }}"
instance_type: "{{ instance_type }}"
image: "{{ image }}"
wait: true
region: "{{ region }}"
aws_access_key: "xxxxxxxxxxxxxxxxxxx"
aws_secret_key: "Xxxxxxxxxxxxxxxxxxx"
register: ec2
- name: Print all ec2 variables
debug: var=ec2
- name: Add all instance public IPs to host group
add_host: hostname={{ item.public_ip }} groups=ec2hosts
with_items: "{{ ec2.instances }}"
- hosts: ec2hosts
remote_user: ec2-user
become: true
gather_facts: false
tasks:
#I need help here, don't know what to do.
- name: Create an EC2 key
ec2_key:
name: "privateKey"
region: "x-x-x"
register: ec2_key
- name: Save private key
copy: content="{{ ec2_key.private_key }}" dest="./privateKey.pem" mode=0600
when: ec2_key.changed
# The Rest is installing LAMP
信息:
1- 我的主机文件是默认的.
Information:
1- My hosts file is default.
2- 我用这个命令来运行剧本:
2- I used this command to run the playbook:
sudo ansible-playbook lamp.yml -vvv -c paramiko
sudo ansible-playbook lamp.yml -vvv -c paramiko
3- launch-wizard-1 具有 SSH.
3- launch-wizard-1 has SSH.
4- myKeyPair 是从我的设备导入到控制台的公钥(不知道是否可以)
4- myKeyPair is a public key imported from my device to the console(don't know if this is ok)
5- 我是个大新手
推荐答案
Ansible 需要在 VM 上安装 Python
才能工作.
Ansible requires Python
installed on VM to work.
这是您需要的代码:
- name: upload an ssh keypair to ec2
hosts: localhost
connection: local
gather_facts: False
vars:
keypair_name: Key_name
key_material: "{{ lookup('file', 'keyfile') }}"
region: "{{ region }}"
tasks:
- name: ssh keypair for ec2
ec2_key:
aws_access_key: "xxxxxxxxxxxxxxxxxxx"
aws_secret_key: "Xxxxxxxxxxxxxxxxxxx"
region: "{{ region }}"
name: "{{ keypair_name }}"
key_material: "{{ key_material }}"
state: present
- name: Power up an ec2 with LAMP stack installed
hosts: localhost
become: true
become_user: root
gather_facts: False
vars:
keypair: myKeyPair
security_group: launch-wizard-1
instance_type: t2.micro
image: ami-47205e28
region: x-x-x
my_user_data: | # install Python: Ansible needs Python pre-installed on the instance to work!
#!/bin/bash
sudo apt-get install python -y
tasks:
- name: Adding Python-pip
apt: name=python-pip state=latest
- name: Install Boto Library
pip: name=boto
- name: Launch instance (Amazon Linux)
ec2:
key_name: "{{ keypair }}"
group: "{{ security_group }}"
instance_type: "{{ instance_type }}"
image: "{{ image }}"
wait: true
wait_timeout: 300
user_data: "{{my_user_data}}"
region: "{{ region }}"
aws_access_key: "xxxxxxxxxxxxxxxxxxx"
aws_secret_key: "Xxxxxxxxxxxxxxxxxxx"
register: ec2
- name: Add all instance public IPs to host group
add_host: hostname={{ item.public_ip }} groups=ec2hosts
with_items: "{{ ec2.instances }}"
