Go Connect Milvus

This topic describes how to connect to and disconnect from the Milvus server.

Before performing any operations, make sure you are connected to the Milvus server.

Milvus supports two ports, port 19530 and port 9091:

• Port 19530 is used for gRPC. When using different Milvus SDKs to connect to the Milvus server, this port is used by default.
• Port 9091 is used for the RESTful API. This port is used when connecting to the Milvus server using an HTTP client.

The following examples connect to the Milvus server with the host as localhost and the port as 19530 or 9091, and then disconnect from the server. If the connection is refused, try unblocking the corresponding port.
