集群版本介绍

clickhouse是表级别的集群，一个clickhouse实例可以有分布式表，也可以有本地表。本文介绍4个节点的clickhouse情况下部署配置。

分布式表数据分成2个分片，2个副本，总共4份数据：

• 节点1数据：分片1，副本1
• 节点2数据：分片1，副本2
• 节点3数据：分片2，副本1
• 节点4数据：分片2，副本2

分片1，分片2组成一份完整的数据。这种配置可以在使用中4个节点共同处理一个sql查询，在一个节点宕机情况下保证数据不丢失，

集群版ClickHouse部署

集群版本与单机版本区别在于节点间要相互发现，与单机版部署区别如下：

• 需要静态配置其他节点信息，配置clickhouse keeper（也可以单独部署zookeeper）

以192.168.1.10，192.168.1.11，192.168.1.12，192.168.1.13四台集群模式为例配置/etc/clickhouse-server/config.d/config.xml

实际部署时需批量替换上述4个ip
