DLF can save the host connection information required for scripts and jobs. If the host connection information changes, you only need to edit it on the Host Connection Management page, but do not need to edit it in scripts or jobs one by one.

Creating a Host Connection

Ensure that the quantity of host connections is less than the maximum connection quota (20).

Log in to the DLF console.
In the navigation tree of the Data Development console, choose Configuration > Manage Host Connection.

Click Create Host Connection. In the displayed dialog box, set the host connection parameters.

**Table 1** Host connection parameters
Parameter	Mandatory	Description
Host Connection Name	Yes	Name of the host connection. Must consist of 1 to 100 characters, contain only letters, digits, and underscores (_), and be unique.
Host IP Address	Yes	IP address of the host. For details, see "Viewing Details About an ECS" in the Elastic Cloud Server User Guide.
Port	Yes	Port number of the host.
Username	Yes	Username of the host.
Login Mode	Yes	Selects the login mode of the host. Key pair Password
Key Pair	Yes	If Key Pair is the login mode of the host, the user needs to obtain the private key file, upload it to OBS, and select an OBS path. NOTE: The uploaded private key file must be in PEM format, and the uploaded private key file and the public key configured on the host must be in the same key pair.
Key Pair Password	No	This parameter does not need to be configured if the key pair does not have password.
Password	Yes	If the login mode of the host is to use a password, enter a login password.
CDM Cluster	Yes	Name of the Cloud Data Migration (CDM) cluster.
KMS Key	Yes	Key created on Key Management Service (KMS) and used for encrypting and decrypting user passwords and key pairs. You can select a created key from KMS.
Host Connection Description	No	Descriptive information about the host connection.

Click Test to test connectivity to the host. If the host can be connected, the host connection has been successfully created.
Click OK.

Editing a Host Connection

After a host connection is created, you can modify host connection parameters as required.

Log in to the DLF console.
In the navigation tree of the Data Development console, choose Configuration > Manage Host Connection.
In the Operation column of the host connection, click Edit. In the displayed dialog box, modify the host connection parameters as required.

NOTE:

For security purposes, you need to enter the password of the host again when modifying the host connection parameters.
Click Test to test connectivity to the host. If the host can be connected, the host connection has been successfully created.
Click OK.

Deleting a Host Connection

If you do not need to use a host connection any more, perform the following operations to delete the host connection:

Log in to the DLF console.
In the navigation tree of the Data Development console, choose Configuration > Manage Host Connection.
In the Operation column of the host connection, click Delete. The Delete Host Connection dialog box is displayed.
Click OK.

NOTICE:

If you forcibly delete a host connection that is being associated with a script or job, ensure that services are not affected by going to the script or job development page and reassociating an available host connection with the script or job.
