While you can explore the service in detail with our Getting Started and Using Cloud DB Serverless guides, we recommend starting with this quickstart overview to understand the complete workflow. After that, you can create DB clusters in the NAVER Cloud Platform console and easily operate databases. Here's the entire process for using Cloud DB Serverless: [1. Create an application server](/docs/en/db-clouddbserverless-procedure#1%EC%95%A0%ED%94%8C%EB%A6%AC%EC%BC%80%EC%9D%B4%EC%85%98%EC%84%9C%EB%B2%84%EC%83%9D%EC%84%B1) [2. Configure the connection environment](/docs/en/db-clouddbserverless-procedure#2%EC%A0%91%EC%86%8D%ED%99%98%EA%B2%BD%EC%84%A4%EC%A0%95) [3. Test the application server connection](/docs/en/db-clouddbserverless-procedure#3%EC%95%A0%ED%94%8C%EB%A6%AC%EC%BC%80%EC%9D%B4%EC%85%98%EC%84%9C%EB%B2%84%EC%A0%91%EC%86%8D%ED%85%8C%EC%8A%A4%ED%8A%B8) [4. Create DB Clusters](/docs/en/db-clouddbserverless-procedure#4DBCluster%EC%83%9D%EC%84%B1) [5. Set ACG](/docs/en/db-clouddbserverless-procedure#5ACG%EC%84%A4%EC%A0%95) [6. Test DB Cluster connection](/docs/en/db-clouddbserverless-procedure#6DBCluster%EC%A0%91%EC%86%8D%ED%85%8C%EC%8A%A4%ED%8A%B8) ## 1. Create an application server First, create an application server that will communicate with DB Cluster to be created from Cloud DB Serverless on the NAVER Cloud Platform console. To create an application server, navigate to **Menu** > **All Services** > **Compute** > **Server** in the VPC environment of the NAVER Cloud Platform console. For detailed instructions, see: Note This section provides a brief overview of how to create an application server. For more information on full creation methods, see the following guides: - [Server user guide](/docs/en/server-start-vpc) 1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Compute** > **Server**. 2. Click **[Create server]**. 3. Select the server image and click **[Next]**. 4. Enter the required information and click **[Next]**. 5. If you do not have an existing authentication key, then create a new authentication key and click **[Next]**. 6. If you do not have any ACG, create a new one. 7. After the final confirmation, click **[Create server]**. Caution The ACG name of the application server from Step 7 is used when adding ACG to the MySQL Server later on. ## 2. Configure the connection environment To set up a server access environment in the VPC environment of the NAVER Cloud Platform console, you need to set up a public IP. Note This section provides a brief overview of how to set up the access environment. For more information on setting up the access environment, see the following guide: - [Public IP user guide](/docs/en/server-publicip-vpc) ## 3. Test the application server connection Once you complete setting up the access environment, use the terminal program to test if you can connect to the application server properly. - [Download terminal program (PuTTY)](https://www.chiark.greenend.org.uk/~sgtatham/putty/) To test connectivity to the application server using the PuTTY terminal program: 1. Run PuTTY. 2. Enter the IP address and port number acquired from the access environment settings for **Host Name (or IP address)** and **Port**. ![clouddbformysql-start_01](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/clouddbformysql-start_01.png?sv=2026-02-06&spr=https&st=2026-10-28T00%3A59%3A57Z&se=2026-10-28T01%3A59%3A57Z&sr=c&sp=r&sig=n5erpgYZ3DnlxHwwFqHCOROpbF7vzretu%2Bq8CwiMyY0%3D) 3. Click **[Open]**. 4. When the **PuTTY Security Alert** popup appears, click **[Accept]**. ![clouddbformysql-start_02](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/clouddbformysql-start_02.png?sv=2026-02-06&spr=https&st=2026-10-28T00%3A59%3A57Z&se=2026-10-28T01%3A59%3A57Z&sr=c&sp=r&sig=n5erpgYZ3DnlxHwwFqHCOROpbF7vzretu%2Bq8CwiMyY0%3D) 5. When the cmd window for server access appears, enter the password you got from Get admin password. ![clouddbformysql-start_03](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/clouddbformysql-start_03.png?sv=2026-02-06&spr=https&st=2026-10-28T00%3A59%3A57Z&se=2026-10-28T01%3A59%3A57Z&sr=c&sp=r&sig=n5erpgYZ3DnlxHwwFqHCOROpbF7vzretu%2Bq8CwiMyY0%3D) Note You can change the password through the `passwd` commands. ## 4. Create DB Clusters After you complete testing the application server connection, create DB Cluster that will communicate with the application server. To create a DB Cluster without a separate service subscription, navigate to **Menu** > **All Services** > **Database** > **Cloud DB Serverless** in the VPC environment of the NAVER Cloud Platform console. For detailed instructions, see: - [DB Cluster](/docs/en/db-clouddbserverless-dbcluster) ## 5. Set ACG To set up Access Control Group (ACG) for DB clusters of Cloud DB Serverless from the NAVER Cloud Platform console: Note This section provides a brief overview of how to set up ACG. For more information on how to set ACG, see [ACG user guide](/docs/en/server-acg-classic). 1. In the VPC environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services** > **Database** > **Cloud DB Serverless**. 2. Click the **ACG** menu. 3. Click and select the ACG to set up, and then click **[Set ACG]**. - Select the ACG of the DB cluster automatically created. 4. Enter the ACG name of the application server in **Access source**. 5. Enter the port number in **Allowed port**. 6. Click **[Add]**. 7. Click **[Apply]**. ## 6. Test DB Cluster connection To test if you can connect properly to the created MySQL Client by installing the DB cluster: 1. Access the application server, run the following commands, and install MySQL. ``` [root@localhost ~] # sudo dnf install -y mysql-server [root@localhost ~] # sudo systemctl start mysqld ``` - Rocky 8.x - 9.x version 2. Access the DB cluster by executing the following commands. ``` [root@localhost ~] # mysql -h ① Private domain name -u ②user_id -p --port ③DB access port -- Access success examples [root@localhost ~] # mysql -h db-gmcp.cdb.ntruss.com -umysql_dba -p --port 3306 Enter password: ********** Welcome to the MySQL monitor.
