集成 Active Directory

以 admin 身份连接到您的实例并加入 AD 领域。

运行以下命令连接到实例。

$ INSTANCE_ID="i-1234567890abcdef0"

$ PUBLIC_IP=$(aws ec2 describe-instances \
--instance-ids $INSTANCE_ID \
--query "Reservations[0].Instances[0].PublicIpAddress" \
--output text)

$ ssh -i ~/.ssh/keys/keypair.pem ec2-user@$PUBLIC_IP

安装必要的软件并加入该领域。

$ sudo yum -y install sssd realmd oddjob oddjob-mkhomedir adcli samba-common samba-common-tools krb5-workstation openldap-clients policycoreutils-python

将管理员密码替换为您的 admin 密码。

$ ADMIN_PW="asdfASDF1234"

$ echo $ADMIN_PW | sudo realm join -U Admin corp.example.com
Password for Admin:
       

如果上述操作成功，您就加入到了该领域，并可以继续下一步操作。

创建 ReadOnlyUser 和其他用户。

在此步骤中，您将使用在前一步中安装的 adcli 和 openldap-clients 工具。

$ echo $ADMIN_PW | adcli create-user -x -U Admin --domain=corp.example.com --display-name=ReadOnlyUser ReadOnlyUser

$ echo $ADMIN_PW | adcli create-user -x -U Admin --domain=corp.example.com --display-name=user000 user000

验证是否创建了用户：

目录 DNS IP 地址是 Python 脚本的输出。

$ DIRECTORY_IP="192.0.2.254"

$ ldapsearch -x -h $DIRECTORY_IP -D Admin -w $ADMIN_PW -b "cn=ReadOnlyUser,ou=Users,ou=CORP,dc=corp,dc=example,dc=com"

$ ldapsearch -x -h $DIRECTORY_IP -D Admin -w $ADMIN_PW -b "cn=user000,ou=Users,ou=CORP,dc=corp,dc=example,dc=com"

默认情况下，当您使用 ad-cli 创建用户时，该用户将处于禁用状态。

在本地计算机上重置并激活用户密码：

注销 EC2 实例。

directory-id 是 Python 脚本的输出。

$ DIRECTORY_ID="d-abcdef01234567890"

$ aws ds reset-user-password \
--directory-id $DIRECTORY_ID \
--user-name "ReadOnlyUser" \
--new-password "ro-p@ssw0rd" \
--region "region-id"

$ aws ds reset-user-password \
--directory-id $DIRECTORY_ID \
--user-name "user000" \
--new-password "user-p@ssw0rd" \
--region "region-id"

将密码添加到 Secrets Manager 密钥中。

现在您创建了 ReadOnlyUser 并设置了密码，请将其存储在 Amazon ParallelCluster 用于验证登录的密钥中。

使用 Secrets Manager 创建新密钥以将 ReadOnlyUser 的密码作为值。密钥值格式必须仅为纯文本（而不是 JSON 格式）。记下密钥的 ARN，以在后面的步骤中使用。

$ aws secretsmanager create-secret --name "ADSecretPassword" \
--region region_id \
--secret-string "ro-p@ssw0rd" \
--query ARN \
--output text
arn:aws:secretsmanager:region-id:123456789012:secret:ADSecretPassword-1234

在本地生成域证书。

$ PRIVATE_KEY="corp-example-com.key"
CERTIFICATE="corp-example-com.crt"
printf ".\n.\n.\n.\n.\ncorp.example.com\n.\n" | openssl req -x509 -sha256 -nodes -newkey rsa:2048 -keyout $PRIVATE_KEY -days 365 -out $CERTIFICATE

将证书存储到 Secrets Manager，以便以后可以从集群内进行检索。

$ aws secretsmanager create-secret --name example-cert \
  --secret-string file://$CERTIFICATE \
  --region region-id
{
  "ARN": "arn:aws:secretsmanager:region-id:123456789012:secret:example-cert-123abc",
  "Name": "example-cert",
  "VersionId": "14866070-092a-4d5a-bcdd-9219d0566b9c"
}

将以下策略添加到您为将 EC2 实例加入 AD 域而创建的 IAM 角色。

PutDomainCertificateSecrets

{
    "Statement": [
        {
            "Action": [
                "secretsmanager:PutSecretValue"
            ],
            "Resource": [
                "arn:aws:secretsmanager:region-id:123456789012:secret:example-cert-123abc",
            ],
            "Effect": "Allow"
        }
    ]
}

将证书导入 Amazon Certificate Manager (ACM)。

$ aws acm import-certificate --certificate fileb://$CERTIFICATE \
  --private-key fileb://$PRIVATE_KEY \
  --region region-id
{
  "CertificateArn": "arn:aws:acm:region-id:123456789012:certificate/343db133-490f-4077-b8d4-3da5bfd89e72"
}

创建放置在 Active Directory 端点前面的负载均衡器。

$ aws elbv2 create-load-balancer --name CorpExampleCom-NLB \
  --type network \
  --scheme internal \
  --subnets subnet-1234567890abcdef0 subnet-021345abcdef6789 \
  --region region-id
{
  "LoadBalancers": [
    {
      "LoadBalancerArn": "arn:aws:elasticloadbalancing:region-id:123456789012:loadbalancer/net/CorpExampleCom-NLB/3afe296bf4ba80d4",
      "DNSName": "CorpExampleCom-NLB-3afe296bf4ba80d4.elb.region-id.amazonaws.com",
      "CanonicalHostedZoneId": "Z2IFOLAFXWLO4F",
      "CreatedTime": "2022-05-05T12:56:55.988000+00:00",
      "LoadBalancerName": "CorpExampleCom-NLB",
      "Scheme": "internal",
      "VpcId": "vpc-021345abcdef6789",
      "State": {
        "Code": "provisioning"
       },
       "Type": "network",
       "AvailabilityZones": [
         {
           "ZoneName": "region-idb",
           "SubnetId": "subnet-021345abcdef6789",
           "LoadBalancerAddresses": []
         },
         {
           "ZoneName": "region-ida",
           "SubnetId": "subnet-1234567890abcdef0",
           "LoadBalancerAddresses": []
         }
       ],
       "IpAddressType": "ipv4"
    }   
  ]
}

创建以 Active Directory 端点为目标的目标组。

$ aws elbv2 create-target-group --name CorpExampleCom-Targets --protocol TCP \
  --port 389 \
  --target-type ip \
  --vpc-id vpc-021345abcdef6789 \
  --region region-id
{
  "TargetGroups": [
    {
      "TargetGroupArn": "arn:aws:elasticloadbalancing:region-id:123456789012:targetgroup/CorpExampleCom-Targets/44577c583b695e81",
      "TargetGroupName": "CorpExampleCom-Targets",
      "Protocol": "TCP",
      "Port": 389,
      "VpcId": "vpc-021345abcdef6789",
      "HealthCheckProtocol": "TCP",
      "HealthCheckPort": "traffic-port",
      "HealthCheckEnabled": true,
      "HealthCheckIntervalSeconds": 30,
      "HealthCheckTimeoutSeconds": 10,
      "HealthyThresholdCount": 3,
      "UnhealthyThresholdCount": 3,
      "TargetType": "ip",
      "IpAddressType": "ipv4"
    }
  ]
}

将 Active Directory (AD) 端点注册到目标组。

$ aws elbv2 register-targets --target-group-arn arn:aws:elasticloadbalancing:region-id:123456789012:targetgroup/CorpExampleCom-Targets/44577c583b695e81 \
  --targets Id=192.0.2.254,Port=389 Id=203.0.113.237,Port=389 \
  --region region-id

对证书创建 LB 侦听器。

$ aws elbv2 create-listener --load-balancer-arn arn:aws:elasticloadbalancing:region-id:123456789012:loadbalancer/net/CorpExampleCom-NLB/3afe296bf4ba80d4 \
  --protocol TLS \
  --port 636 \
  --default-actions Type=forward,TargetGroupArn=arn:aws:elasticloadbalancing:region-id:123456789012:targetgroup/CorpExampleCom-Targets/44577c583b695e81 \
  --ssl-policy ELBSecurityPolicy-TLS-1-2-2017-01 \
  --certificates CertificateArn=arn:aws:acm:region-id:123456789012:certificate/343db133-490f-4077-b8d4-3da5bfd89e72 \
  --region region-id
  "Listeners": [
  {
    "ListenerArn": "arn:aws:elasticloadbalancing:region-id:123456789012:listener/net/CorpExampleCom-NLB/3afe296bf4ba80d4/a8f9d97318743d4b",
    "LoadBalancerArn": "arn:aws:elasticloadbalancing:region-id:123456789012:loadbalancer/net/CorpExampleCom-NLB/3afe296bf4ba80d4",
    "Port": 636,
    "Protocol": "TLS",
    "Certificates": [
      {
        "CertificateArn": "arn:aws:acm:region-id:123456789012:certificate/343db133-490f-4077-b8d4-3da5bfd89e72"
       }
     ],
     "SslPolicy": "ELBSecurityPolicy-TLS-1-2-2017-01",
     "DefaultActions": [
       {
         "Type": "forward",
         "TargetGroupArn": "arn:aws:elasticloadbalancing:region-id:123456789012:targetgroup/CorpExampleCom-Targets/44577c583b695e81",
         "ForwardConfig": {
           "TargetGroups": [
             {
                "TargetGroupArn": "arn:aws:elasticloadbalancing:region-id:123456789012:targetgroup/CorpExampleCom-Targets/44577c583b695e81"
              }
            ]
          }
        }
      ]
    }
  ]
}

创建托管区以便可以在集群 VPC 内发现该域。

$ aws route53 create-hosted-zone --name corp.example.com \
  --vpc VPCRegion=region-id,VPCId=vpc-021345abcdef6789 \
  --caller-reference "ParallelCluster AD Tutorial"
{
  "Location": "https://route53.amazonaws.com/2013-04-01/hostedzone/Z09020002B5MZQNXMSJUB",
  "HostedZone": {
    "Id": "/hostedzone/Z09020002B5MZQNXMSJUB",
    "Name": "corp.example.com.",
    "CallerReference": "ParallelCluster AD Tutorial",
    "Config": {
         "PrivateZone": true
    },
    "ResourceRecordSetCount": 2
  },
  "ChangeInfo": {
    "Id": "/change/C05533343BF3IKSORW1TQ",
    "Status": "PENDING",
    "SubmittedAt": "2022-05-05T13:21:53.863000+00:00"
  },
  "VPC": {
    "VPCRegion": "region-id",
    "VPCId": "vpc-021345abcdef6789"
  }
}

创建名为 recordset-change.json 并包含以下内容的文件。HostedZoneId 是负载均衡器的规范托管区 ID。

{
  "Changes": [
    {
      "Action": "CREATE",
      "ResourceRecordSet": {
        "Name": "corp.example.com",
        "Type": "A",
        "Region": "region-id",
        "SetIdentifier": "example-active-directory",
        "AliasTarget": {
          "HostedZoneId": "Z2IFOLAFXWLO4F",
          "DNSName": "CorpExampleCom-NLB-3afe296bf4ba80d4.elb.region-id.amazonaws.com",
          "EvaluateTargetHealth": true
        }
      }
    }
  ]
}

将记录集更改提交到托管区，这次使用托管区 ID。

$ aws route53 change-resource-record-sets --hosted-zone-id Z09020002B5MZQNXMSJUB \
  --change-batch file://recordset-change.json
{
  "ChangeInfo": {
    "Id": "/change/C0137926I56R3GC7XW2Y",
    "Status": "PENDING",
    "SubmittedAt": "2022-05-05T13:40:36.553000+00:00"
  }
}

创建包含以下内容的策略文档 policy.json。

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": [
        "secretsmanager:GetSecretValue"
      ],
      "Resource": [
        "arn:aws:secretsmanager:region-id:123456789012:secret:example-cert-abc123"
      ],
      "Effect": "Allow"
    }
  ]
}

创建名为 policy.json 并包含以下内容的策略文档。

$ aws iam create-policy --policy-name ReadCertExample \
  --policy-document file://policy.json
{
  "Policy": {
    "PolicyName": "ReadCertExample",
    "PolicyId": "ANPAUUXUVBC42VZSI4LDY",
    "Arn": "arn:aws:iam::123456789012:policy/ReadCertExample-efg456",
    "Path": "/",
    "DefaultVersionId": "v1",
    "AttachmentCount": 0,
    "PermissionsBoundaryUsageCount": 0,
    "IsAttachable": true,
    "CreateDate": "2022-05-05T13:42:18+00:00",
    "UpdateDate": "2022-05-05T13:42:18+00:00"
  }
}

继续按照 （可选）步骤 2：管理 AD 用户和组 或 步骤 3：创建集群 中的步骤操作。
