Question

我正在尝试使用AWS的最新功能之一，它允许您停止RDS实例。

我跟着this doc说明我需要运行命令： aws rds stop-db-instance --db-instance-identifier mydbinstance但是，当我这样做时，我得到了这个：

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help
aws: error: argument operation: Invalid choice, valid choices are:

add-role-to-db-cluster                   | add-source-identifier-to-subscription
add-tags-to-resource                     | apply-pending-maintenance-action

并继续列出其他RDS命令但不包括stop-db-instance。我更新了我的CLI和我当前的版本：aws-cli/1.11.11 Python/2.7.9 Windows/8 botocore/1.4.68

我错过了什么？

更新

我尝试再次升级aws cli但我回来的是所有内容都是最新的：

C:\Users\n.ihab>aws --version
aws-cli/1.11.11 Python/2.7.9 Windows/8 botocore/1.4.68

在此步骤之前是否需要升级其他内容？

Answer 1

这是一项新功能，自CLI版1.11.95起可用。最新版本为1.11.109。更新到最新的AWS CLI版本，您可以使用stop-db-instance

升级前

$ aws --version
aws-cli/1.11.83 Python/2.7.10 Linux/4.1.17-22.30.amzn1.x86_64 botocore/1.5.46

$ aws rds stop-db-instance    
aws: error: argument operation: Invalid choice, valid choices are:

升级CLI并重启（Linux）

$ sudo pip install awscli --upgrade

升级后

$ aws --version
aws-cli/1.11.109 Python/2.6.9 Linux/4.1.17-22.30.amzn1.x86_64 botocore/1.5.72

$ aws rds stop-db-instance
aws: error: argument --db-instance-identifier is required

通过CLI停止RDS实例
