我是 Clickhouse 的新手，正在尝试入门。我已经安装了能够在我的计算机（ubuntu 16.04）上使用它所需的所有软件包，但是当我使用 clickhouse-client 命令时，我得到以下信息：
ClickHouse client version 20.3.4.10 (official build).
Connecting to localhost:9000 as user default.
Code: 516. DB::Exception: Received from localhost:9000. DB::Exception: default: Authentication failed: password is incorrect or there is no user with such name.
有谁知道我应该做什么？
