推荐答案

这是您问题的简短回答，如果您想要详细信息和完全自动化的角色，请告诉我.谢谢

This is the short answer of your question, if you want detail and fully automated role, please let me know. Thanks

先决条件:

• 智能

Python boto 库

Python boto library

在环境设置中设置 AWS 访问和秘密密钥
(最好在 ~./boto 里面)

Set up the AWS access and secret keys in the environment settings
(best is inside the ~./boto)

为了创建 EC2 实例，请修改您可以在vars"下的ec2_launch.yml"文件中找到的这些参数:

In order to create the EC2 Instance, please modified these parameters that you can find inside the "ec2_launch.yml" file under "vars":

• 区域 # 想要启动实例的地方，美国、澳大利亚、爱尔兰等

• count # 要创建的实例数

• region # where is want to launch the instance(s), USA, Australia, Ireland etc

• count # Number of instance(s), you want to create

一旦你提到了这些参数，请运行以下命令:

Once, you have mentioned these parameter, please run the following command:

ansible-playbook -i 托管 ec2_launch.yml

ansible-playbook -i hosts ec2_launch.yml

hosts 文件的内容:

[local]
localhost

[webserver]

ec2_launch.yml 文件的内容:
