ClickHouse遇到的一些配置导致的报错问题记录
1.OS禁用IPv6后配置：<listen_host>::</listen_host>，该配置支持了IPv4和IPv6，而OS又禁用了IPv6会导致报错如下：
<Error> Application: DB::Exception: Listen [::]:8123 failed: Poco::Exception. Code: 1000, e.code() = 0, DNS error: EAI: Address family for hostname not supported (version 22.3.2.1)
2.interserver_http_host配置不合理，报错如下：
HTTP status code: 500 Internal Server Error, body: Code: 221. DB::Exception: No interserver IO endpoint named DataPartsExchange:/clickhouse/tables/traffic_cluster-02/zkm/replicas/01. (NO_SUCH_INTERSERVER_IO_ENDPOINT)
这个不是报错信息不是很能明显看出是该参配置导致的，对该参数深入理解后看看能否关联上。

3.DB::Exception: There are two exactly the same ClickHouse instances
每个分片每个副本需要配置在单独的节点上。（CK officially supports only one shard/replica per node. ）
4.truncate分布式表无法清除数据，需要truncate对应的本地表。
