安装jdk
安装zk
实现高可用
安装ck
- 添加源
在/etc/apt/sources.list

deb http://repo.yandex.ru/clickhouse/deb/stable/ main/
- 下载ck:
sudo apt-get install dirmngr
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv E0C56BD4
sudo apt-get update
sudo apt-get install clickhouse-client clickhouse-server
- 配置
sudo vim /etc/clickhouse-server/config.xml
#生效如下两个配置,其他不变
<interserver_http_host>ck_server_01</interserver_http_host> <!--填命令hostname -f返回的值-->
<listen_host>0.0.0.0</listen_host> <!--监听IP-->
<timezone>Asia/Shanghai</timezone> <!--设置时区-->
<include_from>/etc/metrica.xml</include_from> <!--添加该参数-->
#保存退出
#创建文件metrika.xml
sudo vim /etc/metrika.xml
#添加如下配置

#保存退出
sudo vim /etc/clickhouse-server/users.xml
#可以更改默认用户default的密码
#其他不必修改
#保存退出
若想更改默认配置文件路径以及数据存放目录路径,可以修改config.xml文件相关配置和/etc/init.d/clickhouse-server文件里面的相关配置。
- 启动
sudo service clickhouse-server start
#clickhouse-client --help
#sudo service clickhouse-server status
#sudo service clickhouse-server restart
- 默认主要配置文件(一般再启动前更改配置中日志,数据存放目录)
启动脚本文件:/etc/init.d/clickhouse-server
全局信息配置文件: /etc/clickhouse-server/config.xml
集群信息配置文件: /etc/metrika.xml
用户信息配置文件:/etc/clickhouse-server/users.xml
客户端配置: /etc/clickhouse-client/
日志:/var/log/clickhouse-server/
data / metadata:/var/lib/clickhouse/
测试
clickhouse-client --help
#连接数据库
clickhouse-client -u default --password password
select 1
show databases
show tables
#批量导入数据方式
#1. 命令行客户端
cat file.csv | clickhouse-client --database=test --query="INSERT INTO test FORMAT CSV";
#2. http客户端
GET 'http://localhost:8123/?query=SELECT 1'
echo 'INSERT INTO t VALUES (1),(2),(3)' | POST 'http://localhost:8123/'
#3. 第三方客户端库
