错误开始ec2实例与ansible

Question

我试图做一个开始与ansible，特别是使用ansible playbook来部署ec2实例，但我不断收到错误。

我跟随代码中发现在这个线程：Best way to launch aws ec2 instances with ansible

我在我自己的细节取代给我下面的

hosts文件：

[local] 
localhost 

[webserver] 

create_instance.yml

--- 
    - name: Provision an EC2 Instance 
    hosts: local 
    connection: local 
    gather_facts: False 
    tags: provisioning 
    # Necessary Variables for creating/provisioning the EC2 Instance 
    vars: 
     instance_type: t2.micro 
     security_group: webserver # Change the security group name here 
     image: ami-f95ef58a # Change the AMI, from which you want to launch  the server 
     region: eu-west-1 # Change the Region 
     keypair: MyKeyPair # Change the keypair name 
     count: 1 

     # Task that will be used to Launch/Create an EC2 Instance 
     tasks: 

    - name: Create a security group 
     local_action: 
     module: ec2_group 
     name: "{{ security_group }}" 
     description: Security Group for webserver Servers 
     region: "{{ region }}" 
     rules: 
     - proto: tcp 
      type: ssh 
      from_port: 22 
      to_port: 22 
      cidr_ip: 0.0.0.0/0 
     - proto: tcp 
      from_port: 80 
      to_port: 80 
      cidr_ip: 0.0.0.0/0 
     rules_egress: 
     - proto: all 
      type: all 
      cidr_ip: 0.0.0.0/0 


    - name: Launch the new EC2 Instance 
    local_action: ec2 
        group={{ security_group }} 
        instance_type={{ instance_type}} 
        image={{ image }} 
        wait=true 
        region={{ region }} 
        keypair={{ keypair }} 
        count={{count}} 
    register: ec2 

    - name: Add the newly created EC2 instance(s) to the local host group (located inside the directory) 
    local_action: lineinfile 
        dest="./hosts" 
        regexp={{ item.public_ip }} 
        insertafter="[webserver]" line={{ item.public_ip }} 
    with_items: ec2.instances 


    - name: Wait for SSH to come up 
    local_action: wait_for 
        host={{ item.public_ip }} 
        port=22 
        state=started 
    with_items: ec2.instances 

    - name: Add tag to Instance(s) 
    local_action: ec2_tag resource={{ item.id }} region={{ region }} state=present 
    with_items: ec2.instances 
    args: 
     tags: 
     Name: webserver  

然后我创建环境变量统计局对我的AWS项，如下所示：

export AWS_ACCESS_KEY=my aws key 
export AWS_SECRET_KEY=my aws secret key 

当我与 须藤ansible-剧本-i主机上运行我的代码create_instance.yml 我得到以下错误：

PLAY [localhost]  ************************************************************** 

TASK: [make one instance] ***************************************************** 
failed: [localhost] => {"failed": true} 
msg: No handler was ready to authenticate. 1 handlers were checked.  ['HmacAuthV4Handler'] Check your credentials 

FATAL: all hosts have already failed -- aborting 

PLAY RECAP ******************************************************************** 
      to retry, use: --limit @/home/ubuntu/create_instance.retry 

localhost     : ok=0 changed=0 unreachable=0 failed=1 

能

人建议我可能会出错的地方？

如果您的主持人无法与您的AWS账户建立连接，则会出现此错误。为此，您需要确保访问密钥已正确设置并具有足够的权限来创建实例。

Ansible在python上工作，并选择python目录。所以确保你使用pip安装了awscli而不是apt-get install awscli。使用sudo pip install awscli。

在文件〜/ .aws/credentials中指定您的访问密钥。

另外请确保您已安装更新版本的boto和python。 请参阅此http://www.dowdandassociates.com/blog/content/howto-install-aws-cli-security-credentials/。这里很好地提到了配置密钥的所有方法。
