Question

我一直在尝试使用AWS SDK创建安全组，但不知何故它无法对其进行身份验证。对于特定的访问密钥和密钥，我提供了管理权限，然后它也无法验证。另一方面，我在AWS S3示例中尝试了相同的凭据，它成功执行。

创建安全组时出现以下错误：

com.amazonaws.AmazonServiceException: AWS was not able to validate the provided access credentials (Service: AmazonEC2; Status Code: 401; Error Code: AuthFailure; Request ID: 1584a035-9a88-4dc7-b5e2-a8b7bde6f43c)

    at com.sunil.demo.ec2.SetupEC2.main(SetupEC2.java:25)

这是Java代码：

public class SetupEC2 {
    AWSCredentials credentials = null;
    AmazonEC2Client amazonEC2Client ;

    public static void main(String[] args) {
        SetupEC2 setupEC2Instance = new SetupEC2();
        setupEC2Instance.init();
        setupEC2Instance.createSecurityGroup();
    }

    public void init(){
        // Intialize AWS Credentials
        try {
            credentials = new BasicAWSCredentials("XXXXXXXX", "XXXXXXXXX");
        } catch (Exception e) {
            throw new AmazonClientException(
                    "Cannot load the credentials from the credential profiles file. " +
                            "Please make sure that your credentials file is at the     correct " +
                            "location (/home/sunil/.aws/credentials), and is in valid format.",
                            e);
        }

        // Initialize EC2 instance
        try {
            amazonEC2Client = new AmazonEC2Client(credentials);
            amazonEC2Client.setEndpoint("ec2.ap-southeast-1.amazonaws.com");
            amazonEC2Client.setRegion(Region.getRegion(Regions.AP_SOUTHEAST_1));
        } catch (Exception e) {

            CreateSecurityGroupResult csgr = amazonEC2Client.createSecurityGroup(createSecurityGroupRequest);

            String groupid = csgr.getGroupId();

Answer 1

尝试更新您的系统时间。

当AWS-datetime与您的日期时间之间的差异太大时，将不接受凭据。

对于Debian / Ubuntu用户：

如果您从未设置时区，则可以使用

执行此操作

sudo dpkg-reconfigure tzdata

停止ntp-Service，因为太大的时间差异，无法通过运行服务来改变。

sudo /etc/init.d/ntp stop

同步您的时间和日期（-q设置时间并退出/仅运行一次）（ - g允许第一次调整为大）（-x转换为600秒/ Adjuste也是时间大的差异）（ - n不要分叉/处理不会去背景）

sudo ntpd -q -g -x -n

重启服务

sudo /etc/init.d/ntp start

检查实际的system-datetime

sudo date

将system-datetime设置为hardware-datetime

sudo hwclock --systohc

显示您的硬件日期时间

sudo hwclock

Answer 2

如果您将凭据放在〜/ .aws / credentials中，则无需为AmazonEC2Client调用提供参数。如果您这样做，那么在EC2实例上，相同的代码将与假定的STS角色一起使用。

Answer 3

“调用[填充空白]操作时发生客户端错误（AuthFailure）：AWS无法验证提供的访问凭据”

如果您对AWS凭证的有效性有信心，即访问密钥和密钥以及相应的个人资料名称，那么您的偏离日期和时间是一个非常好的罪魁祸首。
就我而言，我很自信，但我错了 - 我使用了错误的钥匙。双重检查不会有害。
假设您创建了一个名为“guignol”的IAM用户。在〜/ .aws / config 中配置“guignol”，如下所示：

[profile guignol] region = us-east-1 aws-access-key_id = AKXXXYYY... aws-secret-key-access = ...

如果尚未安装aws cli（命令级接口），请安装它。作为测试，运行 aws ec2 describe-instances --profile guignol 如果你收到aws无法验证凭据的错误消息，请运行 aws configure --profile guignol ，输入您的凭据并再次运行测试命令。

AWS无法验证提供的访问凭据
