Connect to the Server

This article describes how to connect to a Milvus server from a Python client.

See Python API documentation for details about APIs.

We recommend using Milvus Sizing Tool to estimate the hardware resources required for the data.

Import pymilvus:

# Import pymilvus.
>>> from milvus import Milvus, IndexType, MetricType, Status

Use any of the following methods to connect to the Milvus server:
```
# Connect to the Milvus server.
>>> milvus = Milvus(host='localhost', port='19530')
```
In the above code, host and port both use default values. You can change them to your IP address and port.
```
>>> milvus = Milvus(uri='tcp://localhost:19530')
```
