Creating a Distributed Programming Project

Procedure

1. Click in the shortcut menu bar on the left pane or click next to Development Assistant. The Kunpeng Application Projects page is displayed. See Figure 1.
   Figure 1 Kunpeng Application Projects
   
2. Click Distributed Application. On the Distributed Application tab page that is displayed, set Project Type to Template project or Empty project. Select a sample project and set the other parameters. See Figure 2 and Figure 3.
   Figure 2 Creating a distributed programming project
   
   Figure 3 Creating an empty project
   
   

   When an empty project is created, a directory of the corresponding project is also created, with the file content being empty.

3. Click Next to configure the target node. You can use an existing server or add a new server. To add a server, enter the IP address, SSH port, user name, password, and storage directory. If you select Configure later, no SDKs will be deployed by default. See Figure 4.
   Figure 4 Configuring the target node
   

   

   When configuring the new target node, ensure that the node is running on a physical or virtual machine and runs openEuler 20.03 LTS SP1, openEuler 22.03 LTS SP1, or CentOS 7.6 in the Kunpeng architecture, and that you have administrator permissions for the node.

4. Determine whether to deploy the SDK. If you select Yes, select Online deployment or Offline deployment. See Figure 5. Click Create.

   Table 1 Parameters for creating a distributed programming project

   Parameter	Description
   Project Type	The options are: Template project Distributed programming Empty project
   Project Name	The default project name is xxx_ProjectN, which can be modified as required. Name of the project to be created. NOTE: N is an integer starting from 1 in ascending order. The project name can contain 1 to 64 characters, including only letters, digits, periods (.), hyphens (-), plus signs (+), parentheses (), and underscores (_). It cannot start with a period (.).
   Project Location	The default project location is C:\Users\username\KunpengProject, which can be modified as required. Storage path of the project to be created.
   Deploy Server	Existing New Configure later NOTE: The new server will be added to the target server management.
   Node Properties	The options are: Client node Server node
   IP Address	IP address of the target node for subsequent operations.
   SSH Port	SSH port number of the target node.
   User Name	Account of the target node for subsequent operations.
   Password	Password of the target node user.
   Remember password	If you select this option, the password of the current server user will be remembered.
   Storage Directory	Storage directory on the target node. NOTE: The tool reads and writes the content in the storage directory. To avoid data loss, you are advised to use an empty directory.
   Deploy SDK	Select an SDK deployment method. Online deployment kunpeng-hcom kunpeng-hcom-devel Offline deployment kunpeng-hcom kunpeng-hcom-devel NOTE: If you select Online deployment, the server must be connected to the Internet. In an isolated network environment, you need to use a proxy to access the Internet. For details, see Configuring a Proxy. If you select Offline deployment, the SDK is imported from the local host. Download the SDK to the local host and upload it.

5. During project creation, the corresponding module content is verified. You can click Terminate Configuration on the verification page to stop the current verification. If the verification is successful, the module content on the right is displayed in green. If the verification fails, the content is displayed in red.

   • If the parameters fail to be set, check the network connection and reconfigure the parameters.
   • If the verification fails in online SDK deployment mode, click Retry. If the verification fails in offline SDK deployment mode, click Retry, or click reselect and upload to upload the SDK and perform another verification.
6. After the project is created, click Open Project to open it in the current window.

   After the project is created, you can compile, run, and debug the server application using the Compiler and Debugger. Before running and debugging the client application, you need to manually start the server application on the server. For details, see the README file in the src folder of the project.

7. If the distributed application project fails to be created, click Reconfigure.
