Import clusters¶
This topic introduces how to import clusters using Dashboard. The current version only supports importing clusters deployed by the official DEB or RPM packages and clusters created by Dashboard. Currently, importing clusters deployed by Docker and Kubernetes is not supported.
Steps¶
Caution
In the same cluster, the service versions need to be unified. Importing Nebula Graph examples from different versions in the same cluster is not supported.
-
In the configuration file of each service, change the IP in
<meta|graph|storage>_server_addrs
andlocal_ip
to the server's IP, and then start Nebula Graph.For details, see Configurations and Manage Nebula Graph services.
-
In the Cluster management page, click Import cluster.
-
In the Import cluster page, enter the information of Connect to Nebula Graph.
- Graphd Host:
:n . In this example, the IP is 192.168.8.157:9669
. - Username: The account to connect to Nebula Graph. In this example, the username is
vesoft
. - Password: The password to connect to Nebula Graph. In this example, the password is
nebula
.
Note
By default, authentication is disabled in Nebula Graph. Therefore, you can use
root
as the username and any password to connect to Nebula Graph. When authentication is enabled in Nebula Graph, you need to use the specified username and password to connect to Nebula Graph. For details of authentication,see Nebula Graph manual. - Graphd Host:
-
In the Connect to Nebula Graph page, fill in the following:
- Enter the cluster name, 15 characters at most. In this example, the cluster name is
create_1027
. - Authorize the node. The SSH username and password of each node are required.
-
Batch authorization requires uploading the CSV file. Edit the authentication information of each node according to the downloaded CSV file. Ensure that the node information is correct, otherwise upload failure may happen.
-
If the node status on the page becomes authorized, the node authentication is successful.
- Enter the cluster name, 15 characters at most. In this example, the cluster name is
-
Ensure that all nodes are authorized successfully. Click Import cluster.
Next to do¶
After the cluster is successfully imported, you can operate the cluster. For details, see Overview.
