<a name="CHAP_Tutorials.WebServerDB.CreateDBCluster"></a>

Create an Amazon Aurora MySQL or Aurora PostgreSQL DB cluster that maintains the data used by a web application.

------
#### [ Aurora MySQL ]

**To create an Aurora MySQL DB cluster**

1. Sign in to the Amazon Web Services Management Console and open the Amazon RDS console at [https://console.amazonaws.cn/rds/](https://console.amazonaws.cn/rds/).

1. In the upper-right corner of the Amazon Web Services Management Console, make sure the Amazon Web Services Region is the same as the one where you created your EC2 instance.

1. In the navigation pane, choose **Databases**.

1. Choose **Create database**.

1. On the **Create database** page, choose **Standard create**.

1. For **Engine options**, choose **Aurora (MySQL Compatible)**.  
![Select engine type](http://docs.amazonaws.cn/en_us/AmazonRDS/latest/AuroraUserGuide/images/aurora-engine-options-mysql.png)

   Keep the default values for **Version** and the other engine options.

1. In the **Templates** section, choose **Dev/Test**.  
![Select template](http://docs.amazonaws.cn/en_us/AmazonRDS/latest/AuroraUserGuide/images/tutorial-create-template-2.png)

1. In the **Settings** section, set these values:
   + **DB cluster identifier** – Type **tutorial-db-cluster**.
   + **Master username** – Type **tutorial\_user**.
   + **Auto generate a password** – Leave the option turned off.
   + **Master password** – Type a password.
   + **Confirm password** – Retype the password.

1. In the **Instance configuration** section, set these values:
   + **Burstable classes (includes t classes)**
   + **db.t3.small** or **db.t3.medium**
**Note**  
We recommend using the T DB instance classes only for development and test servers, or other non-production servers. For more details on the T instance classes, see [DB instance class types](Concepts.DBInstanceClass.Types.md).  
![Instance configuration section](http://docs.amazonaws.cn/en_us/AmazonRDS/latest/AuroraUserGuide/images/Tutorial_WebServer_DB_instance_small_aurora.png)

1. In the **Availability and durability** section, use the default values.

1. In the **Connectivity** section, set these values and keep the other values as their defaults:
   + For **Compute resource**, choose **Connect to an EC2 compute resource**.
   + For **EC2 instance**, choose the EC2 instance you created previously, such as **tutorial-ec2-instance-web-server**.  
![Connectivity section](http://docs.amazonaws.cn/en_us/AmazonRDS/latest/AuroraUserGuide/images/Tutorial_WebServer_Connectivity.png)

1. Open the **Additional configuration** section, and enter **sample** for **Initial database name**. Keep the default settings for the other options.

1. To create your Aurora MySQL DB cluster, choose **Create database**.

   Your new DB cluster appears in the **Databases** list with the status **Creating**.

1. Wait for the **Status** of your new DB cluster to show as **Available**. Then choose the DB cluster name to show its details.

1. In the **Connectivity & security** section, view the **Endpoint** and **Port** of the writer DB instance.

   Note the endpoint and port for your writer DB instance. You use this information to connect your web server to your DB cluster.

1. Complete [Install a web server on your EC2 instance](CHAP_Tutorials.WebServerDB.CreateWebServer.md).
