我在本地系统中创建了一个表： CREATE TABLE default.test_distributed (a Int8) ENGINE = Distributed(logs, default, test_remote)

并在 IP 10.121.21.33 的远程系统中创建了一个表：create table test_remote (a Int8) Engine=Log

然后我在本地系统中插入数据：插入 test_distributed values (1011)

然后我触发了 Select query : select * from test_distributed

并得到以下异常：2017.05.02 18:49:36.155606 [14] ConnectionPoolWithFailover：尝试 №1 连接失败，原因：代码：210，e.displayText() = DB::NetException: Connection refused: (10.121.21.33: 9000), e.what() = DB::NetException 2017.05.02 18:49:36.155982 [14] ConnectionPoolWithFailover: 尝试 №2 时连接失败，原因：代码：210，e.displayText() = DB::NetException:连接被拒绝：(10.121.21.33:9000)，e.what() = DB::NetException 2017.05.02 18:49:36.156316 [14] ConnectionPoolWithFailover：尝试 №3 连接失败，原因：代码：210，e.displayText () = DB::NetException: 连接被拒绝: (10.121.21.33:9000), e.what() = DB::NetException 2017.05.02 18:49:36.162780 [4] executeQuery: 代码: 279, e.displayText( ) = DB::NetException: 所有连接尝试均失败。日志：

检查本地系统上的设置

SELECT * FROM system.clusters

并检查以下文件 /etc/clickhouse-server/config.xml 的 remote_servers 部分

请参阅https://clickhouse.yandex/reference_en.html#Distributed for remote_servers 示例配置
