Question

我是Ansible的新手，并按照this tutorial创建一个安全组和一个ec2实例。安全组已成功创建，但ec2实现了ec2实例失败：

错误：无法识别的参数： /home/ec2-user/.ansible/tmp/ansible-tmp-14244 ....

我确实正确设置了aws凭证和不可变变量，如下所示

# AWS Credentials
export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=xxx

# EC2 Environment Variables
export ANSIBLE_HOSTS=/etc/ansible/ec2.py
export EC2_INI_PATH=/etc/ansible/ec2.ini

文件和输出如下所示。对这个问题的任何想法？谢谢你的帮助！

# Variables listed here are applicable to all host groups 
key_name: sobrr-staging.pem
aws_region: cn-north-1

key_name ec2模块中的Ansible参数是指您在AWS账户中上传或创建的ssh公钥（如果您想重用之前的密钥）。您可能希望验证它是否与您在AWS账户中指定的名称相匹配。

我的猜测是您的AWS账户中的密钥名称是sobrr-staging，而不是sobrr-staging.pem

尝试使用sobrr-staging，看看情况如何。

通过Ansible创建EC2实例因ec2失败：错误：无法识别的参数：
