  在本地测试 ClickHouse 分布式表时，创建分布式表成功，但是查询数据时报错，完整报错如下：

Received exception from server (version 22.3.2):
Code: 516. DB::Exception: Received from localhost:9000. DB::Exception: Received from 192.168.68.123:9000. DB::Exception: default: Authentication failed: password is incorrect or there is no user with such name. (AUTHENTICATION_FAILED)

  排查许久后发现，是集群开始安装时设置了密码，而配置分布式表时，没有添加各服务器的用户名和密码，所以访问不到别的服务器的数据，在我们的/etc/clickhouse-server/config.xml中，加入用户名和密码即可正常查询数据，如下：

  修改完成后，分布式表即查询成功：
