Question

我正在使用Bitnami Zookeeper AMI for AWS并配置了3节点群集。我已经在我的Clickhouse配置文件中指定了它们，如下所示。

<zookeeper>
        <node index="1">
                 <host>X.X.X.X</host>
                <port>2181</port>
        </node>
        <node index="2">
                <host>X.X.X.X</host>
                <port>2181</port>
        </node>
        <node index="3">
                <host>X.X.X.X</host>
                <port>2181</port>
        </node>
</zookeeper>
<macros>
        <shard>01</shard>
        <replica>ec2-X-X-X-X.compute-1.amazonaws.com</replica>
</macros>

现在，当我尝试在我的Clickhouse节点之一上使用以下查询创建ReplicatedMergeTree表时

CREATE TABLE ontime_replica (Year UInt16,
Month UInt8,
DayofMonth UInt8,
FlightDate Date
)
ENGINE = ReplicatedMergeTree(
'/clickhouse/tables/{shard}/ontime',
'{replica}',
FlightDate,
(Year, FlightDate),
8192);

我收到以下异常

Query execution failed

Reason:
SQL Error [999]: ClickHouse exception, code: 999, host: <Clickhouse node IP>, port: 
8123; Code: 999, e.displayText() = Coordination::Exception: Not 
authenticated, path: /clickhouse, e.what() = Coordination::Exception

在我的动物园管理员日志中，我收到以下消息

2019-01-29 09:44:44,991 [myid:2] - INFO  [ProcessThread(sid:2 
cport:-1)::PrepRequestProcessor@653] - Got user-level KeeperException when

Answer 1

已添加

skipACL=yes

在我的zookeeper配置中跳过身份验证。

Answer 2

要使用登录名和密码连接到zookeeper，您应该这样配置ClickHouse：

<yandex>
    <zookeeper>
        <node index="1">
            <host>X.X.X.X</host>
            <port>2181</port>
        </node>
        <node index="2">
            <host>Y.Y.Y.Y</host>
            <port>2181</port>
        </node>
        <node index="3">
            <host>Z.Z.Z.Z</host>
            <port>2181</port>
        </node>
        <identity>user:password</identity>
    </zookeeper>
</yandex>

更改配置后，您将需要重新启动ClickHouse服务器。
