配置防火墙Configure firewall

Azure Databases for MySQL 受防火墙保护。Azure Databases for MySQL are protected by a firewall. 默认情况下,会拒绝与服务器和服务器内数据库的所有连接。By default, all connections to the server and the databases inside the server are rejected. 首次连接到 Azure Database for MySQL 之前,请配置防火墙以添加客户端计算机的公共网络 IP 地址(或 IP 地址范围)。Before connecting to Azure Database for MySQL for the first time, configure the firewall to add the client machine's public network IP address (or IP address range).

  1. 单击新创建的服务器,并单击“连接安全性” 。Click your newly created server, and then click Connection security.


  2. 可以“添加我的 IP” 或在此处配置防火墙规则。You can Add My IP, or configure firewall rules here. 创建规则后请记得单击“保存” 。Remember to click Save after you have created the rules. 现在可以使用 mysql 命令行工具或 MySQL Workbench GUI 工具连接服务器。You can now connect to the server using mysql command-line tool or MySQL Workbench GUI tool.


Azure Database for MySQL 通过端口 3306 进行通信。Azure Database for MySQL server communicates over port 3306. 如果尝试从企业网络内部进行连接,则该网络的防火墙可能不允许经端口 3306 的出站流量。If you are trying to connect from within a corporate network, outbound traffic over port 3306 may not be allowed by your network's firewall. 如果是这样,则无法连接到 Azure MySQL 服务器,除非 IT 部门打开了端口 3306。If so, you cannot connect to Azure MySQL server unless your IT department opens port 3306.

获取连接信息Get connection information

从 Azure 门户获取 Azure Database for MySQL 服务器的完全限定 服务器名称服务器管理员登录名Get the fully qualified Server name and Server admin login name for your Azure Database for MySQL server from the Azure portal. 使用 mysql 命令行工具通过完全限定的服务器名称连接到服务器。You use the fully qualified server name to connect to your server using mysql command-line tool.

  1. Azure 门户中,单击左侧菜单中的“所有资源” ,键入名称,然后搜索“Azure Database for MySQL 服务器”。In Azure portal, click All resources from the left-hand menu, type the name, and search for your Azure Database for MySQL server. 选择服务器名称以查看详细信息。Select the server name to view the details.

  2. 在“概述” 页上,记下 服务器名称服务器管理员登录名From the Overview page, note down Server Name and Server admin login name. 可以单击每个字段旁边的“复制”按钮,将其复制到剪贴板。You may click the copy button next to each field to copy to the clipboard. 4-2 服务器属性

在此示例中,服务器名称是 mydemoserver.mysql.database.chinacloudapi.cn,服务器管理员登录名是 myadmin@mydemoserverIn this example, the server name is mydemoserver.mysql.database.chinacloudapi.cn, and the server admin login is myadmin@mydemoserver.

使用 mysql 连接服务器Connect to the server using mysql

使用 mysql 命令行工具建立与 Azure Database for MySQL 服务器的连接。Use mysql command-line tool to establish a connection to your Azure Database for MySQL server.

键入命令以建立连接:Type the command to connect:

mysql -h mydemoserver.mysql.database.chinacloudapi.cn -u myadmin@mydemoserver -p

创建空数据库Create a blank database

连接到服务器后,立即创建一个要使用的空数据库。Once you're connected to the server, create a blank database to work with.


出现提示时,请运行以下命令,切换为连接此新建的数据库:At the prompt, run the following command to switch connection to this newly created database:

USE mysampledb;

在数据库中创建表Create tables in the database

现已介绍了如何连接 Azure Database for MySQL 数据库,接下来你可以完成一些基本任务:Now that you know how to connect to the Azure Database for MySQL database, you can complete some basic tasks:

首先,创建表并加载一些数据。First, create a table and load it with some data. 创建一个存储清单信息的表。Let's create a table that stores inventory information.

CREATE TABLE inventory (
    id serial PRIMARY KEY, 
    name VARCHAR(50), 
    quantity INTEGER

将数据加载到表Load data into the tables

表格创建好后,可向其插入一些数据。Now that you have a table, insert some data into it. 在打开的命令提示窗口中,运行以下查询来插入几行数据。At the open command prompt window, run the following query to insert some rows of data.

INSERT INTO inventory (id, name, quantity) VALUES (1, 'banana', 150);
INSERT INTO inventory (id, name, quantity) VALUES (2, 'orange', 154);

现已将两行示例数据加载到了之前创建的表中。Now you have two rows of sample data into the table you created earlier.

查询和更新表中的数据Query and update the data in the tables

执行以下查询,从数据库表中检索信息。Execute the following query to retrieve information from the database table.

SELECT * FROM inventory;

还可以更新表中的数据。You can also update the data in the tables.

UPDATE inventory SET quantity = 200 WHERE name = 'banana';

检索数据时行也会相应进行更新。The row gets updated accordingly when you retrieve data.

SELECT * FROM inventory;

将数据库还原到以前的时间点Restore a database to a previous point in time

假设你意外删除了一个重要的数据库表,并且无法轻松地恢复数据。Imagine you have accidentally deleted an important database table, and cannot recover the data easily. 使用 Azure Database for MySQL 可以将服务器还原到某个时间点,并在新服务器中创建数据库的副本。Azure Database for MySQL allows you to restore the server to a point in time, creating a copy of the databases into new server. 可以使用此新服务器恢复已删除的数据。You can use this new server to recover your deleted data. 以下步骤将示例服务器还原到添加此表之前的时间点。The following steps restore the sample server to a point before the table was added.

  1. 在 Azure 门户中,找到 Azure Database for MySQL。In the Azure portal, locate your Azure Database for MySQL. 在“概述” 页上,单击工具栏上的“还原” 。On the Overview page, click Restore on the toolbar. 此时将打开“还原”页。The Restore page opens.

    10-1 还原数据库

  2. 使用必需信息填充“还原” 窗体。Fill out the Restore form with the required information.

    10-2 还原窗体

    • 还原点:在列出的时间范围内选择要还原到的时间点。Restore point: Select a point-in-time that you want to restore to, within the timeframe listed. 请确保将本地时区转换为 UTC。Make sure to convert your local timezone to UTC.
    • 还原到新服务器:提供一个要还原到的新服务器名称。Restore to new server: Provide a new server name you want to restore to.
    • 位置:该区域与源服务器相同,不能更改。Location: The region is same as the source server, and cannot be changed.
    • 定价层:定价层与源服务器相同,不能更改。Pricing tier: The pricing tier is the same as the source server, and cannot be changed.
  3. 单击“确定” ,将服务器还原到删除该表之前的时间点Click OK to restore the server to restore to a point in time before the table was deleted. 还原服务器时将创建服务器的新副本(从指定的时间点开始)。Restoring a server creates a new copy of the server, as of the point in time you specify.

清理资源Clean up resources

如果将来不再需要这些资源,可以通过删除资源组或只删除 MySQL 服务器来删除它们。If you don't expect to need these resources in the future, you can delete them by deleting the resource group or just delete the MySQL server. 若要删除资源组,请执行以下步骤:To delete the resource group, follow these steps:

  1. 在 Azure 门户中,搜索并选择“资源组”。In the Azure portal, search for and select Resource groups.
  2. 在资源组列表中,选择你的资源组的名称。In the resource group list, choose the name of your resource group.
  3. 在资源组的概述页面中,选择“删除资源组”。In the Overview page of your resource group, select Delete resource group.
  4. 在确认对话框中,键入资源组的名称,然后选择“删除”。In the confirmation dialog box, type the name of your resource group, and then select Delete.
