如何创建并使用 AWS Cli 管理 ec2实例
https://us-east-2.console.aws.amazon.com/ec2/home?region=us-east-2#Home:
前置条件
密钥对
容量
安全组
1 创建一个密钥对
aws> ec2 create-key-pair --key-name kgptalkie --query 'KeyMaterial' --output text > kgptalkie.pem
aws>
2 添加只读权限
~ via 🅒 base
➜ chmod 400 kgptalkie.pem
~ via 🅒 base
➜
3 描述密钥对
~ via 🅒 base
➜ aws-shell
aws> ec2 describe-key-pairs --key-names kgptalkie

4 删除密钥对
aws> ec2 delete-key-pair --key-name kgptalkie
-------------------------------------
| DeleteKeyPair |
+------------------------+----------+
| KeyPairId | Return |
+------------------------+----------+

使用 Aws 创建安全组并更新
aws> ec2 create-security-group --group-name my-sg --description "my sg group" --vpc-id vpc-0202e1374ee1fbf85
-------------------------------------
| CreateSecurityGroup |
