  • clickhouse安装和入门

    1. 安装 

    https://clickhouse.tech/#quick-start

    centos: 

    sudo yum install yum-utils
    sudo rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
    sudo yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64
    sudo yum install clickhouse-server clickhouse-client
    
    sudo /etc/init.d/clickhouse-server start
    clickhouse-client

    如果在线安装很慢时,可以先下载得到rpm包,在安装:

     启动:sudo /etc/init.d/clickhouse-server start

    2. 目录配置

    Server config files are located in /etc/clickhouse-server/. Before going further, please notice the <path> element in config.xml. Path determines the location for data storage, so it should be located on volume with large disk capacity; the default value is /var/lib/clickhouse/.If you want to adjust the configuration, it’s not handy to directly edit config.xml file, considering it might get rewritten on future package updates. The recommended way to override the config elements is to create files in config.d directory which serve as “patches” to config.xml.

    The default location for server logs is /var/log/clickhouse-server/. The server is ready to handle client connections once it logs the Ready for connections message.

    修改目录:

     把数据存放目录都配置到 /data/clickhouse/ 目录下面。

    3. 建表

    先启动clickhouse: 

    sudo /etc/init.d/clickhouse-server start
    clickhouse-client --query "CREATE DATABASE IF NOT EXISTS tutorial"

    4. clickhouse-client 客户端工具

     clickhouse-client -m 可以支持多行SQL;

    5. 建表:

    clickhouse-client -m 

    然后执行:

    CREATE TABLE tutorial.hits_v1

    6. 导入数据

    clickhouse-client --query "INSERT INTO tutorial.hits_v1 FORMAT TSV" --max_insert_block_size=100000 < hits_v1.tsv

    7. 执行sql

    clickhosue-client -m

    然后输入SQL:

    速度杠杠的!
