ClickHouse最簡單的安裝方法

 

 

 

安裝包地址：

https://packagecloud.io/Altinity/clickhouse

 

無需下載安裝包，更新yum源即可！！

 

 

最后： yum install -y clickhouse-server clickhouse-client  即可完成安裝！！！

 

配置之后如果使用DBevaver連接不上，原因是需要修改config.xml的listen，由127.0.0.1修改本地ip地址或者0.0.0.0  

 

 

創建表報錯：clickhouse  Can't create replicated table without ZooKeeper

 

原因：zookeeper配置錯了：

 

 

 

 

 當你打開cluster表時候發現錯誤一般是沒有配置分片組！！

CREATE TABLE utab
(
    EventDate DateTime,
    CounterID UInt32,
    UserID UInt32
) ENGINE = ReplicatedMergeTree('/clickhouse/tables/{shard}/hits', '{replica}')
PARTITION BY toYYYYMM(EventDate)
ORDER BY (CounterID, EventDate, intHash32(UserID))
SAMPLE BY intHash32(UserID)



INSERT into utab values ('2018-11-22 08:08:08',1,1);


SELECT * from utab;


CREATE TABLE utab_all (
    EventDate DateTime,
    CounterID UInt32,
    UserID UInt32
) ENGINE = Distributed('ck-daxin', 'default', 'utab', toYYYYMM(EventDate)) ;




SELECT count(1) from utab_all;
