Click Admin Console to get started. Note: It takes 10-15 minutes to open successfully

Step 6: Enter the console

Switch to the regional console as shown in the figure, and you can observe the list of database clusters being created

Step 7: Set the cluster whitelist

You need to set the IP whitelist of the cluster and create the initial account of the cluster before you can connect and use the cluster

1. Click the cluster ID as shown in the figure.
   
   2. In the left navigation bar, click Configuration and Management > Cluster Whitelist .
   
   3. On the cluster whitelist page, you can add an IP whitelist group or configure an existing whitelist.
   
   4. Click Add IP Whitelist Group .
   In the Add IP whitelist group panel, enter the group name and the IP whitelist addresses that are allowed to be accessed.
   The IP address in the white list includes: the IP address of your own computer, the public IP address of the cloud server (it will be mentioned later when deploying the cloud server). The way to obtain the
   
   IP address of your computer is to enter the IP in Baidu.
   

Step 8: Set up the cluster security group

If there is no optional security group, please skip this step for now

On the Cluster Whitelist page in Step 7 , click the Configure button in the Select Security Group or Target Security Group action bar to change the security group settings. In the pop-up Select Security Group panel, select the target security group and click OK .

Step 9: Create a database high-privilege account

1. Go back to the PolarDB console .
2. In the upper left corner of the console, select the region where the cluster is located.
3. Find the target cluster and click the cluster ID.
4. In the left navigation bar, select Configuration and Management > Account Management .
5. Click Create Account .
6. In the account creation panel, set the following parameters and click OK:
   

Step 10: Apply for a public network address

1. Log in to the PolarDB console .
2. In the upper left corner of the console, select the region where the cluster is located.
3. Find the target cluster and click the cluster ID.
4. In the link address area of ​​the basic information page , click the icon in the upper right corner to switch views. Click Apply . In the displayed dialog box, set the connection address prefix and click OK .
   
   

Step 11: Use DMS to connect to the cluster

DMS is a graphical data management tool provided by Alibaba Cloud. It is a data management service that integrates data management, structure management, access security, BI charts, data trends, data traces, performance and optimization, and server management. It supports the management of relational databases (MySQL, SQL Server, PostgreSQL, etc.) and NoSQL databases (MongoDB, Redis, etc.), and also supports Linux server management.

1. Log in to the PolarDB console .
2. In the upper left corner of the console, select the region where the cluster is located.
3. Find the target cluster and click the cluster ID.
4. In the upper right corner of the basic information page, click Login Database . In the pop-up dialog box, enter the database account and database password
   
   created in the PolarDB MySQL cluster , and click Login . Note: Remember the database account and password, which will be used later. 1. After logging in, click to authorize to authorize. 2. Click the logged-in instance . In the list of logged-in instances , click the name of the target cluster, find and double-click the name of the target database to switch to the target database for management.
   
   
   
   
   
   
   

Step 12: Create a database

1. Right-click the logged-in instance name and select Database Management

2. Click Create Library

3. Enter the database name and click OK

Step Thirteen: Import Data

Just import the SQL file

other (no action required)

Supports main address links and cluster address (recommended) links, the differences are as follows

• Cluster address and master address
  

address type	address description	Supported Network Types
Cluster address (recommended)	Applications only need to connect to a cluster address to connect to multiple nodes. With the read-write separation function, the write request will be automatically sent to the master node, and the read request will be automatically sent to the master node or read-only node according to the load of each node. Explain that PolarDB includes a default cluster address, and you can also create multiple custom cluster addresses according to business needs. The custom cluster address can be connected to a specified node, and set the read-write mode, etc. For details, see Modifying and releasing cluster addresses .	Private network Public network Private network (classic network)
primary address	Always connected to the master node, supports read and write operations. When the master node fails, the master access address will automatically switch to the new master node.

• Private network address and public network address

Network Type	illustrate	scenes to be used
private network	The best performance of PolarDB can be exerted by accessing the connection address of the private network. When creating a cluster, a private network connection address is generated by default. This address supports modification but cannot be released. For how to modify it, see Modifying the connection address and port .	For example, if the ECS and the database cluster are located in the same VPC, then the ECS can access the database cluster through the private network address. Use DMS to access the database cluster through VPC
public net	You can apply for or release a connection address of the public network. For details, see Applying for a connection address and releasing a connection address . The public network is the Internet, accessing through the public network will not achieve the best performance of PolarDB.	For example: Access the database cluster through the public network for maintenance operations.
Private network (classic network)	You can apply for or release a private network (classic network) connection address. For details, see Applying for a connection address and releasing a connection address . Clusters are not isolated through the network, and can only rely on the whitelist policy of the cluster itself to block illegal access. For details, see Setting the cluster whitelist .	Only when the business is in the classic network, the database cluster can be accessed through the private network address (classic network).
