Question

数据不会复制到每个Clickhouse副本。检查Clickhouse-server日志时，它会显示

DB :: StorageReplicatedMergeTree :: queueTask（）::: Poco :: Exception。代码：1000，e.code（）= 0，e.displayText（）=找不到主机：ip-172-1-140-243（版本19.9.2.4）

我同时安装Clickhouse和Zookeeper的每台计算机上都有3台不同的计算机。我正在尝试使用Zookeeper设置3节点Clickhouse群集。我已按照以下步骤进行配置https://blog.uiza.io/replicated-and-distributed-on-clickhouse-part-2/。我已经在所有Clickhouse实例上创建了表和副本，并在zookeeper中进行了验证。在zookeeper中为所有副本创建了目录。在所有实例上都创建了/etc/metrica.xml，zoo.cfg，/etc/clickhouse-server/config.xml。提供1个实例中的全部3个文件

/etc/metrica.xml文件

要更改所有副本中的复制数据应该属于所有实例

Answer 1

机器之间是否可以访问Clickhouse和Zookeeper端口？

就像，您可以运行wget http://172.1.140.243:9000吗？相同的方法分别适用于Zookeper端口。

Answer 2

您似乎需要在两个节点（ 172.1.34.199 和 172.1.73.156 ）的主机文件中添加字符串< / p>

172.1.140.243 ip-172-1-140-243

使用Zookeeper设置Clickhouse 3节点循环集群时，clickhouse副本/服务器无法相互连接
