1 单节点安装

1 安装curl工具
yum install -y curl

2 添加clickhouse的yum镜像
curl -s https://packagecloud.io/install/repositories/altinity/clickhouse/script.rpm.sh | sudo bash

3 检查镜像情况
[[email protected] yum.repos.d]# yum list | grep clickhouse                        

clickhouse-client.x86_64                    20.5.4.40-1.el7            @Altinity_clickhouse

clickhouse-common-static.x86_64             20.5.4.40-1.el7            @Altinity_clickhouse

4 安装clickhouse的服务端和客户端
yum install -y clickhouse-server clickhouse-client

5 启动服务daunt
service clickhouse-server start

6 启动交互式客户端
clickhouse-client -m

客户端支持的参数如下:

 

2 集群安装 

clickhouse的集群安装就是在每台机器上安装CH的服务端以及客户端!!所以在每台机器上重复单机安装步骤!

1)修改/etc/clickhouse-server/目录下的config.xml
<listen_host>::</listen_host>
<!-- <listen_host>::1</listen_host> -->
<!-- <listen_host>127.0.0.1</listen_host> -->
2)将修改好的配置文件分发到其他CH节点上
3)在/etc/下创建集群配置文件metrika.xml文件(这个文件需要创建),在CH启动的时候会加载这个配置文件以集群的形式启动CH

metrika.xml文件配置内容

<clickhouse_remote_servers>
    <doit_ch_cluster1>
        <shard>
             <internal_replication>true</internal_replication>

在每台机器上启动CH服务.以集群的形式启动 , 如果想要再以单节点的形式启动那么就删除/etc/下的

metrika.xml文件即可单节点的形式启动!
