先决条件Prerequisites
若要完成本教程，请确保做好以下准备：To complete this tutorial, make sure you have:
在此步骤中，你将创建逻辑 SQL 服务器和使用 AdventureWorksLT 示例数据的单一数据库。In this step, you create a logical SQL server and a single database that uses AdventureWorksLT sample data.可以通过使用 Azure 门户菜单和屏幕，或通过使用 Azure CLI 或 PowerShell 脚本来创建数据库。You can create the database by using Azure portal menus and screens, or by using an Azure CLI or PowerShell script.
所有方法都包括设置服务器级防火墙规则，以允许用于访问服务器的计算机的公共 IP 地址。All the methods include setting up a server-level firewall rule to allow the public IP address of the computer you're using to access the server.有关创建服务器级防火墙规则的详细信息，请参阅创建服务器级防火墙。For more information about creating server-level firewall rules, see Create a server-level firewall.还可以设置数据库级防火墙规则。You can also set database-level firewall rules.请参阅创建数据库级防火墙规则。See Create a database-level firewall rule.

本教程的此部分使用以下 PowerShell cmdlet：This portion of the tutorial uses the following PowerShell cmdlets:
设置数据库的属性，或将现有数据库移到弹性池中。Sets properties for a database, or moves an existing database into an elastic pool.
3 - 创建故障转移组3 - Create the failover group
此步骤在现有的服务器与另一区域中的新服务器之间创建一个故障转移组。In this step, you will create a failover group between an existing server and a new server in another region.然后，将弹性池添加到该故障转移组。Then add the elastic pool to the failover group.
使用 Azure 门户创建故障转移组。Create your failover group using the Azure portal.
在 Azure 门户的左侧菜单中选择“所有服务”，然后选择“SQL 弹性池”。Select All services in the left-hand menu of the Azure portal, then select SQL elastic pools.
选择在上一部分中创建的弹性池，例如 myElasticPool。Select the elastic pool created in the previous section, such as myElasticPool.
在“概述”窗格上，选择 服务器名称 下的服务器名称以打开服务器的设置。On the Overview pane, select the name of the server under Server name to open the settings for the server.
在“设置”窗格下选择“故障转移组”，然后选择“添加组”以创建新的故障转移组。 Select Failover groups under the Settings pane, and then select Add group to create a new failover group.
在“故障转移组”页上输入或选择以下值，然后选择“创建”： On the Failover Group page, enter or select the following values, and then select Create:
故障转移组名称：键入唯一的故障转移组名称，例如 failovergrouptutorial。Failover group name: Type in a unique failover group name, such as failovergrouptutorial.
辅助服务器：选择“配置所需设置”选项，然后选择“创建新服务器”。Secondary server: Select the option to configure required settings and then choose to Create a new server.或者，可以选择现有的服务器作为辅助服务器。Alternatively, you can choose an already-existing server as the secondary server.为新的辅助服务器输入以下值之后，选择“选择”。After entering the following values for your new secondary server, select Select.
服务器名称：键入辅助服务器的唯一名称，例如 mysqlsecondary。Server name: Type in a unique name for the secondary server, such as mysqlsecondary.
服务器管理员登录名：键入 azureuserServer admin login: Type azureuser
密码：键入符合密码要求的复杂密码。Password: Type a complex password that meets password requirements.
位置：从下拉列表中选择一个位置，例如“中国北部 2”。Location: Choose a location from the drop-down, such as China North 2.此位置不能与主服务器的位置相同。This location cannot be the same location as your primary server.
备注
服务器登录名和防火墙设置必须与主服务器相匹配。The server login and firewall settings must match that of your primary server.
选择“组中的数据库”，然后选择在第 2 部分创建的弹性池。Select Databases within the group then select the elastic pool you created in section 2.此时应会出现一条警告，提示你将在辅助服务器上创建弹性池。A warning should appear, prompting you to create an elastic pool on the secondary server.选择该警告，然后选择“确定”以在辅助服务器上创建弹性池。Select the warning, and then select OK to create the elastic pool on the secondary server.
选择“选择”以将弹性池设置应用到故障转移组，然后选择“创建”以创建故障转移组。 Select Select to apply your elastic pool settings to the failover group, and then select Create to create your failover group.将弹性池添加到故障转移组的操作会自动启动异地复制过程。Adding the elastic pool to the failover group will automatically start the geo-replication process.

本教程的此部分使用以下 PowerShell cmdlet：This portion of the tutorial uses the following PowerShell cmdlets:
此步骤将故障转移组故障转移到辅助服务器，然后使用 Azure 门户故障回复。In this step, you will fail your failover group over to the secondary server, and then fail back using the Azure portal.
选择在上一部分中创建的弹性池，例如 myElasticPool。Select the elastic pool created in the previous section, such as myElasticPool.
在 服务器名称 下选择服务器的名称以打开服务器的设置。Select the name of the server under Server name to open the settings for the server.
在“设置”窗格下选择“故障转移组”，然后选择在第 2 部分创建的故障转移组。 Select Failover groups under the Settings pane and then choose the failover group you created in section 2.
查看哪个服务器是主服务器，哪个服务器是辅助服务器。Review which server is primary, and which server is secondary.
在“任务”窗格中选择“故障转移”，以故障转移包含弹性池的故障转移组。Select Failover from the task pane to fail over your failover group containing your elastic pool.
在告知将会断开 TDS 会话连接的警告中选择“是”。Select Yes on the warning that notifies you that TDS sessions will be disconnected.
查看哪个服务器是主服务器，哪个服务器是辅助服务器。Review which server is primary, which server is secondary.如果故障转移成功，这两个服务器的角色应会交换。If failover succeeded, the two servers should have swapped roles.
再次选择“故障转移”，将故障转移组故障回复到原始设置。Select Failover again to fail the failover group back to the original settings.
使用 PowerShell 测试故障转移组的故障转移。Test failover of your failover group using PowerShell.
# Set variables for your server and database
# $subscriptionId = '<SubscriptionID>'
# $resourceGroupName = "myResourceGroup-$(Get-Random)"
# $location = "China East 2"

# $drLocation = "China North 2"
# $drServerName = "mysqlsecondary-$(Get-Random)"
# $failoverGroupName = "failovergrouptutorial-$(Get-Random)"
# Check role of secondary replica
Write-host "Confirming the secondary server is secondary...."
(Get-AzSqlDatabaseFailoverGroup `

本教程的此部分使用以下 PowerShell cmdlet：This portion of the tutorial uses the following PowerShell cmdlets:
选择“删除资源组”即可删除该资源组中的所有资源以及该组本身。Select Delete resource group to delete all the resources in the group, as well as the resource group itself.
在文本框中键入资源组的名称 myResourceGroup，然后选择“删除”以删除该资源组。Type the name of the resource group, myResourceGroup, in the textbox, and then select Delete to delete the resource group.
使用 PowerShell 清理资源。Clean up your resources using PowerShell.
# Set variables for your server and database
# $resourceGroupName = "myResourceGroup-$(Get-Random)"
# Clean up resources by removing the resource group
Write-host "Removing resource group..."
Remove-AzResourceGroup -ResourceGroupName $resourceGroupName
Write-host "Resource group removed =" $resourceGroupName
本教程的此部分使用以下 PowerShell cmdlet：This portion of the tutorial uses the following PowerShell cmdlet:
若要保留资源组但删除辅助数据库，请先将其从故障转移组中移除，然后再将其删除。If you want to keep the resource group but delete the secondary database, remove it from the failover group before deleting it.如果在从故障转移组中移除辅助数据库之前将其删除，则可能会导致不可预知的行为。Deleting a secondary database before it is removed from the failover group can cause unpredictable behavior.
没有适用于 Azure 门户的脚本。There are no scripts available for the Azure portal.
