推荐答案

这是您问题的简短答案，如果您想获得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：

• Ansible

• Ansible

Python boto库

Python boto library

在环境设置

（最好在〜。/ boto内部）

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

要创建EC2实例，请修改这些参数，您可以在 vars下的 ec2_launch.yml文件中找到这些参数：

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

• 区域编号要在其中启动实例的地方，美国，澳大利亚，爱尔兰等



• count＃您要创建的实例数

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

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

您已经提到了这些参数，请运行以下命令：

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

ansible-playbook -i主机ec2_launch.yml

ansible-playbook -i hosts ec2_launch.yml

主机文件的内容：

[local]
localhost

[webserver]

ec2_launch.yml 文件的内容：
