TR-4998 ： AWS EC2 中的 Oracle HA 搭配 Pacemaker 叢集和 FSX ONTAP

10/10/2024 貢獻者

NetApp公司的Alleno Cao、Niyazz Mohamed

本解決方案提供概觀與詳細資料、可在 Redhat Enterprise Linux （ RHEL ）上使用 Pacemaker 叢集功能、在 AWS EC2 中啟用 Oracle 高可用度（ HA ）、並在 Amazon FSX ONTAP 中透過 NFS 傳輸協定啟用資料庫儲存 HA 。

目的

許多致力於在公有雲中自我管理及執行 Oracle 的客戶、都需要克服一些挑戰。其中一項挑戰是為 Oracle 資料庫提供高可用度。傳統上、 Oracle 客戶仰賴稱為「 Real Application Cluster 」或 RAC 的 Oracle 資料庫功能、在多個叢集節點上提供雙主動式交易支援。一個故障節點不會停止應用程式處理。可惜的是、 Oracle RAC 實作並不容易在許多常見的公有雲（例如 AWS EC2 ）中使用或支援。透過在 RHEL 和 Amazon FSX ONTAP 中運用內建的 Pacemaker 叢集（ PCS ）、客戶無需 Oracle RAC 授權成本、即可在運算和儲存設備上實現主動被動式叢集、以支援 AWS 雲端中的關鍵任務 Oracle 資料庫工作負載。

本文件說明如何在 RHEL 上設定 Pacemaker 叢集、在 EC2 和 Amazon FSX ONTAP 上部署 Oracle 資料庫、搭配 NFS 傳輸協定、在 Pacemaker for HA 中設定 Oracle 資源、以及在最常見的 HA 情境下進行驗證的示範。此解決方案也提供 NetApp SnapCenter UI 工具的快速 Oracle 資料庫備份、還原及複製資訊。

本解決方案可解決下列使用案例：

在 RHEL 中設定和組態 Pacemaker HA 叢集。
在 AWS EC2 和 Amazon FSX ONTAP 中部署 Oracle 資料庫 HA 。

目標對象

本解決方案適用於下列人員：

DBA 希望在 AWS EC2 和 Amazon FSX ONTAP 中部署 Oracle 。
想要在 AWS EC2 和 Amazon FSX ONTAP 中測試 Oracle 工作負載的資料庫解決方案架構設計師。
想要在 AWS EC2 和 Amazon FSX ONTAP 中部署及管理 Oracle 資料庫的儲存管理員。
想要在 AWS EC2 和 Amazon FSX ONTAP 中備份 Oracle 資料庫的應用程式擁有者。

解決方案測試與驗證環境

此解決方案的測試與驗證是在實驗室環境中執行、可能與最終部署環境不符。請參閱一節部署考量的關鍵因素以取得更多資訊。

NTAP_PDB1 、 NTAP_PDB2 、 NTAP_PDB3 ）容錯移轉時

/u01 、 /u02 、 /u03 NFS 會在容錯移轉時掛載

部署考量的關鍵因素

* Amazon FSX ONTAP HHA *根據預設、 Amazon FSX ONTAP 會在單一或多個可用區域的一對儲存控制器中進行資源配置。它以主動 / 被動的方式為關鍵任務資料庫工作負載提供儲存備援。儲存容錯移轉對終端使用者來說是透明的。儲存容錯移轉時不需要使用者介入。
* PCS 資源群組和資源訂購。 *資源群組可讓多個具有相依性的資源在同一個叢集節點上執行。資源順序會以相反的方式強制執行資源啟動順序和關機順序。
* 偏好的節點。 *Pacemaker 叢集專門部署於主動 / 被動式叢集（非 Pacemaker 的要求）、並與 FSX ONTAP 叢集同步。如果可用且位置限制、則使用中的 EC2 執行個體會設定為 Oracle 資源的慣用節點。
* 待機節點上的 Fence 延遲。 *在雙節點 PC 叢集中、仲裁會人工設為 1 。當叢集節點之間發生通訊問題時、任一節點都可能會嘗試隔離另一個節點、這可能會導致資料毀損。在待機節點上設定延遲可減輕此問題、並可讓主節點在備用節點被圍起來時繼續提供服務。
* 多個 AZ 部署考量。 *此解決方案是在單一可用性區域中部署及驗證。在多 AZ 部署中、需要額外的 AWS 網路資源、才能在可用性區域之間移動 PC 浮動 IP 。
* Oracle 資料庫儲存配置。 *在本解決方案示範中、我們為測試資料庫 NTAP 配置三個資料庫磁碟區、以裝載 Oracle 二進位、資料和記錄檔。這些磁碟區會以 /u01 - 二進位、 /u02 - 資料和 /u03 - 記錄檔透過 NFS 裝載在 Oracle DB 伺服器上。雙控制檔是在 /u02 和 /u03 掛載點上設定、以提供備援。
* DNFS 組態。 * 使用 DNFS （自 Oracle 11g 起提供）、在 DB VM 上執行的 Oracle 資料庫可提供比原生 NFS 用戶端更多的 I/O 。依預設、自動化 Oracle 部署會在 NFSv3 上設定 DNFS 。
* 資料庫備份。 * NetApp 提供 SnapCenter 軟體套件、以方便使用者的 UI 介面進行資料庫備份、還原及複製。NetApp 建議實作這樣的管理工具、以快速（在一分鐘內）備份快照、快速（分鐘）資料庫還原及資料庫複製。

解決方案部署

以下各節提供在 AWS EC2 中部署和組態 Oracle 資料庫 HA 的逐步程序、其中包含 Pacemaker 叢集、以及用於資料庫儲存保護的 Amazon FSX ONTAP 。

部署的先決條件

Details

部署需要下列先決條件。

已設定AWS帳戶、並已在AWS帳戶中建立必要的VPC和網路區段。
在安裝最新版 Ansible 和 Git 的情況下、將 Linux VM 配置為 Ansible 控制器節點。如需詳細資訊、請參閱下列連結： "NetApp解決方案自動化入門" 在第 - 節中
Setup the Ansible Control Node for CLI deployments on RHEL / CentOS 或
Setup the Ansible Control Node for CLI deployments on Ubuntu / Debian。

在 Ansible 控制器和 EC2 執行個體 DB VM 之間啟用 ssh 公開 / 私密金鑰驗證。

佈建 EC2 執行個體和 Amazon FSX ONTAP 儲存叢集

Details

雖然 EC2 執行個體和 Amazon FSX ONTAP 可以從 AWS 主控台手動進行佈建、但建議您使用 NetApp Terraform 型自動化工具套件來自動化配置 EC2 執行個體和 FSX ONTAP 儲存叢集。以下是詳細的程序。

從 AWS CloudShell 或 Ansible 控制器 VM 複製一份 EC2 和 FSX ONTAP 的自動化工具套件複本。
```
git clone https://bitbucket.ngage.netapp.com/scm/ns-bb/na_aws_fsx_ec2_deploy.git
```
如果工具組並非從 AWS CloudShell 執行、則您的 AWS 帳戶需要使用 AWS 使用者帳戶存取 / 秘密金鑰配對來執行 AWS CLI 驗證。

請參閱工具套件中的 readme.md 檔案。視需要修改 main.tf 和相關參數檔案、以取得必要的 AWS 資源。

An example of main.tf:

resource "aws_instance" "orapm01" {
  ami                           = var.ami
  instance_type                 = var.instance_type
  subnet_id                     = var.subnet_id
  key_name                      = var.ssh_key_name

  root_block_device {
    volume_type                 = "gp3"
    volume_size                 = var.root_volume_size
  }

  tags = {
    Name                        = var.ec2_tag1
  }
}

resource "aws_instance" "orapm02" {
  ami                           = var.ami
  instance_type                 = var.instance_type
  subnet_id                     = var.subnet_id
  key_name                      = var.ssh_key_name

  root_block_device {
    volume_type                 = "gp3"
    volume_size                 = var.root_volume_size
  }

  tags = {
    Name                        = var.ec2_tag2
  }
}

resource "aws_fsx_ontap_file_system" "fsx_01" {
  storage_capacity              = var.fs_capacity
  subnet_ids                    = var.subnet_ids
  preferred_subnet_id           = var.preferred_subnet_id
  throughput_capacity           = var.fs_throughput
  fsx_admin_password            = var.fsxadmin_password
  deployment_type               = var.deployment_type

  disk_iops_configuration {
    iops                        = var.iops
    mode                        = var.iops_mode
  }

  tags                          = {
    Name                        = var.fsx_tag
  }
}

resource "aws_fsx_ontap_storage_virtual_machine" "svm_01" {
  file_system_id                = aws_fsx_ontap_file_system.fsx_01.id
  name                          = var.svm_name
  svm_admin_password            = var.vsadmin_password
}

驗證並執行 Terraform 方案。成功執行會在目標 AWS 帳戶中建立兩個 EC2 執行個體和一個 FSX ONTAP 儲存叢集。自動化輸出會顯示 EC2 執行個體 IP 位址和 FSX ONTAP 叢集端點。
```
terraform plan -out=main.plan
```
```
terraform apply main.plan
```

這將完成適用於 Oracle 的 EC2 執行個體和 FSX ONTAP 資源配置。

Pacemaker 叢集設定

Details

適用於 RHEL 的高可用度附加元件是叢集式系統、可為 Oracle 資料庫服務等關鍵正式作業服務提供可靠性、擴充性和可用度。在此使用案例示範中、會設定並設定雙節點節律器叢集、以支援主動 / 被動叢集案例中 Oracle 資料庫的高可用度。

以 EC2 使用者身分登入 EC2 both 執行個體、完成 EC2 執行個體的下列工作：

移除 AWS Red Hat Update Infrastructure （ RHUI ）用戶端。
```
sudo -i yum -y remove rh-amazon-rhui-client*
```

向 Red Hat 註冊 EC2 執行個體 VM 。

sudo subscription-manager register --username xxxxxxxx --password 'xxxxxxxx' --auto-attach

啟用 RHEL 高可用度 rpm 。

sudo subscription-manager config --rhsm.manage_repos=1

sudo subscription-manager repos --enable=rhel-8-for-x86_64-highavailability-rpms

安裝起搏器和導板。

sudo yum update -y

sudo yum install pcs pacemaker fence-agents-aws

為所有叢集節點上的 hacluster 使用者建立密碼。對所有節點使用相同的密碼。
```
sudo passwd hacluster
```

啟動 PCS 服務、並讓其在開機時啟動。

sudo systemctl start pcsd.service

sudo systemctl enable pcsd.service

驗證 PCSD 服務。

sudo systemctl status pcsd

[ec2-user@ip-172-30-15-5 ~]$ sudo systemctl status pcsd

172.30.15.5     ip-172-30-15-5.ec2.internal

安裝並設定 awscli, 以連線至 AWS 帳戶。

sudo yum install awscli

sudo aws configure

如果尚未安裝，請安裝 resource-agents 套件。
```
sudo yum install resource-agents
```

在 `only one`叢集節點上、完成下列工作以建立 PC 叢集。

驗證 PC 使用者 hacluster 。

sudo pcs host auth ip-172-30-15-5.ec2.internal ip-172-30-15-111.ec2.internal

[ec2-user@ip-172-30-15-111 ~]$ sudo pcs host auth ip-172-30-15-5.ec2.internal ip-172-30-15-111.ec2.internal

Pacemaker 叢集隔離組態

Details

正式作業叢集必須具備 Pacemaker 隔離組態。它可確保 AWS EC2 叢集上發生故障的節點會自動隔離、防止節點消耗叢集的資源、損害叢集的功能、或毀損共用資料。本節說明如何使用 Fence_AWS 隔離代理程式來設定叢集隔離。

以 root 使用者身分、輸入下列 AWS 中繼資料查詢、以取得每個 EC2 執行個體節點的執行個體 ID 。

echo $(curl -s http://169.254.169.254/latest/meta-data/instance-id)

[root@ip-172-30-15-111 ec2-user]# echo $(curl -s http://169.254.169.254/latest/meta-data/instance-id)
i-0d8e7a0028371636f

or just get instance-id from AWS EC2 console

輸入下列命令以設定 Fence 裝置。使用 PCM1_host_map 命令、將 RHEL 主機名稱對應至執行個體 ID 。請使用 AWS 存取金鑰和 AWS 使用者帳戶的 AWS 秘密存取金鑰、您先前用於 AWS 驗證。

sudo pcs stonith \

將 stonith 動作設為關、而非在叢集層級重新開機。

如果將 stonith 動作設為 off 、則圍籬叢集節點一開始就會關機。在 stonith POWER_timeout （ 240 秒）中定義的期間之後、會重新啟動圍籬節點、並重新加入叢集。

將待機節點的 Fence delay （隔離延遲）設為 10 秒。

執行 `pcs stonith refresh`命令以重新整理停止的 stonith Fence 代理程式或清除失敗的 stonith 資源動作。

在 PC 叢集中部署 Oracle 資料庫

Details

我們建議使用 NetApp 提供的 Ansible 教戰手冊、在 PCS 叢集上以預先定義的參數執行資料庫安裝和組態工作。對於這項自動化 Oracle 部署、三個使用者定義的參數檔案需要使用者輸入才能執行教戰手冊。

主機：定義自動化教戰手冊所針對的目標。
VARS/vars.yml - 定義適用於所有目標的變數的全域變數檔案。
host_vars/host_name.yml - 定義僅適用於命名目標的變數的本機變數檔案。在我們的使用案例中、這些是 Oracle DB 伺服器。

除了這些使用者定義的變數檔案之外、還有幾個預設變數檔案、其中包含預設參數、除非必要、否則不需要變更。以下顯示在 PCS 叢集組態中於 AWS EC2 和 FSX ONTAP 中自動部署 Oracle 的詳細資料。

從 Ansible 控制器管理使用者主目錄中、複製 NetApp Oracle 部署自動化工具套件 for NFS 的複本。
```
git clone https://bitbucket.ngage.netapp.com/scm/ns-bb/na_oracle_deploy_nfs.git
```
Ansible 控制器可與資料庫 EC2 執行個體位於同一部 VPC 、或只要兩者之間有網路連線、則可位於內部部署。

在 hosts 參數檔中填入使用者定義的參數。以下是典型主機檔案組態的範例。

[admin@ansiblectl na_oracle_deploy_nfs]$ cat hosts
#Oracle hosts
[oracle]
orapm01 ansible_host=172.30.15.111 ansible_ssh_private_key_file=ec2-user.pem
orapm02 ansible_host=172.30.15.5 ansible_ssh_private_key_file=ec2-user.pem

在 vars/vars.yml 參數檔案中填入使用者定義的參數。以下是典型 vars.yml 檔案組態的範例。

[admin@ansiblectl na_oracle_deploy_nfs]$ cat vars/vars.yml

部署後 HA 驗證

Details

部署之後、務必執行一些測試與驗證、以確保 PC Oracle 資料庫容錯移轉叢集已正確設定、並能如預期般運作。測試驗證包括受管理的容錯移轉、模擬非預期的資源故障、以及叢集保護機制的還原。

手動觸發待命節點的隔離功能、以驗證節點隔離、並觀察待命節點是否已離線、並在逾時後重新開機。
