使用 zookeeper 设置 clickhouse 3 节点循环集群时，clickhouse replica/server 无法相互连接

Question

数据没有被复制到每个 clickhouse 副本。在检查 clickhouse-server 日志时显示

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）

我有 3 台不同的机器，每台机器上都安装了 clickhouse 和 zookeeper。我正在尝试使用 zookeeper 设置 3 节点 clickhouse 集群。我已按照这些步骤进行配置 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。已在所有实例上创建 /etc/metrica.xml 、 zoo.cfg 、 /etc/clickhouse-server/config.xml 。提供 1 个实例的所有 3 个文件

/etc/metrica.xml 文件

我应该更改什么以获取属于所有实例的所有副本中的复制数据

Answer 1

clickhouse 和 zookeeper 端口在机器之间是否可以访问？

比如，你可以运行 wget http://172.1.140.243:9000 吗？同样适用于 zookeper 端口。

Answer 2

看起来您需要添加到 hosts-两个节点的文件（172.1.34.199 和 172.1 .73.156) 字符串

172.1.140.243 ip-172-1-140-243
