如何使用SIOS DataKeeper在AWS EC2中配置较少SANSQL Server群集

In this article, we will review how to configure SAN less SQL Server cluster in AWS EC2 instances using SIOS DataKeeper.

在本文中，我们将回顾如何使用SIOS DataKeeper在AWS EC2实例中配置SAN较少SQL Server群集。

SQL Server clustering is a high availability feature which failover the SQL Server resources to the secondary node in case of a failure in the primary node. The data is stored in the shared drive and will be accessible to the active node in the cluster. In case of failover, we do not need to transfer jobs, logins, linked server or server scoped triggers, etc. to the other node as the instance is the same.

SQL Server群集是一项高可用性功能，如果主节点发生故障，该功能会将SQL Server资源故障转移到辅助节点。数据存储在共享驱动器中，并且群集中的活动节点可以访问该数据。如果发生故障转移，我们不需要将作业，登录名，链接的服务器或服务器范围的触发器等转移到另一个节点，因为实例是相同的。

Please refer to the below image which shows the traditional SQL Server failover cluster using shared disks. The shared disks are active on the NODE1 which is active, and the SQL server services are running on NODE1. The users connect to the instance using a virtual SQL Server cluster name or IP address which routes the request to the active node in the cluster.

请参考下图，该图显示了使用共享磁盘的传统SQL Server故障转移群集。共享磁盘在活动的NODE1上处于活动状态，并且SQL Server服务在NODE1上运行。用户使用虚拟SQL Server群集名称或IP地址连接到实例，该名称或IP地址将请求路由到群集中的活动节点。

使用SIOS DataKeeperSQL Server群集 (SQL Server clustering using SIOS DataKeeper)

SIOS DataKeeper allows us to build the SQL Server cluster on cloud environments without the need for shared storage.

SIOS DataKeeper允许我们在云环境上构建SQL Server群集，而无需共享存储。

The data in the disk on the primary node is mirrored to the secondary node. Please refer to the below image for SAN less SQL Server cluster using SIOS DataKeeper.

主节点上磁盘中的数据已镜像到辅助节点。请参考下图，了解使用SIOS DataKeeper的SAN较少SQL Server群集。

NODE1 will have its disk and NODE2 will have its disk. SIOS DataKeeper will replicate the data to the other node synchronously or asynchronously based on the option we choose.

NODE1将拥有其磁盘，而NODE2将拥有其磁盘。 SIOS DataKeeper将根据我们选择的选项将数据同步或异步复制到另一个节点。

The following are the steps involved in configuring the SAN less SQL Server cluster in AWS EC2 instances.

以下是在AWS EC2实例中配置SAN较少SQL Server群集所涉及的步骤。

Launch two instances and add them to one domain 启动两个实例并将它们添加到一个域
Configure windows failover cluster 配置Windows故障转移群集
Attach a volume to both instances 将卷附加到两个实例
Configure SIOS jobs to replicate the data 配置SIOS作业以复制数据
Install the SQL Server failover cluster 安装SQL Server故障转移群集

Let go over these steps one by one.

让我们一步一步地完成这些步骤。

For demo purpose, I am launching a Windows server 2016 base from AWS console to installing active directory services and make it as a domain controller. For production servers please configure domain controller with all the security and firewall rules you need.

出于演示目的，我将从AWS控制台启动Windows Server 2016 base，以安装活动目录服务并将其用作域控制器。对于生产服务器，请为域控制器配置所需的所有安全和防火墙规则。

Log in to the AWS and navigate to the EC2 console. Click on Launch an instance and search for Windows Server 2016 base image. Select the image as shown in the below image.

登录到AWS并导航到EC2控制台。单击启动实例，然后搜索Windows Server 2016基本映像。选择图像，如下图所示。

Choose the Instance type. In this case, I choose t2.medium Configure the instance details and add the storage. Choose the security group if you already have one or create a new one. While launching the instance choose the key pair and make sure you have the key pair which will be used to connect the instance later.

选择实例类型。在这种情况下，我选择t2.medium配置实例详细信息并添加存储。选择安全组（如果已有）或创建一个新的安全组。在启动实例时，请选择密钥对，并确保您具有将在以后用于连接实例的密钥对。

After four or five minutes the instance will be available for use. For identification purposes, I am naming it as “Domain Controller”.

四，五分钟后，该实例即可使用。为了便于识别，我将其命名为“域控制器”。

Now select the instance and click on Connect.

现在选择实例，然后单击“连接”。

Click on Get Password. upload the .pem which was used to launch the instance. Click on decrypt the password.

Once the prerequisites check is successful, click on Install. Once the installation completes the server will reboot.

前提条件检查成功后，单击“ 安装”。 安装完成后，服务器将重新启动。

After reboot, RDP to the server again. Launch Active Directory Users and Computers. Create a new user and add it Administrators and Domain Controllers, Domain Computers, Domain Administrators group.

重新引导后，再次将RDP连接到服务器。启动Active Directory用户和计算机 。创建一个新用户并将其添加到“ 管理员和域控制器” ，“域计算机”，“ 域管理员”组中。

启动两个实例并将它们添加到一个域 (Launch two instances and add them to one domain)

In this demo, I am setting up a two-node SQL Server cluster. So, I am launching two new nodes and join them to the domain we created above. These two nodes will be part of the cluster.

在此演示中，我将设置一个两节点SQL Server群集。因此，我要启动两个新节点，并将它们加入到上面创建的域中。这两个节点将成为群集的一部分。

There are two ways to launch the instances. One is launching the instances using EC2 console and install SIOS DataKeeper with your license. The other way is subscribing to SIOS DataKeeper in the AWS Market place and launch the instance from there. This way EC2 instance comes with SIOS pre-installed.

有两种启动实例的方法。一种是使用EC2控制台启动实例，然后使用许可证安装SIOS DataKeeper。另一种方法是在AWS Market地方订阅SIOS DataKeeper并从那里启动实例。这样，EC2实例预装了SIOS。

In this demo, we will use a subscription model.

在此演示中，我们将使用订阅模型。

To subscribe for SIOS data keeper, Navigate to AWS Market Place subscriptions. Click on Discover products.

要订阅SIOS数据管理员，请导航至AWS Market Place订阅 。单击发现产品 。

On node1 launch the SIOS DataKeeper. Click on Connect to server.

在节点1上，启动SIOS DataKeeper。单击连接到服务器。

Enter node1 and click on Connect.
