ClickHous安装

1.下载
下载地址：https://packagecloud.io/Altinity/clickhouse
2.上传rpm
上传rpm包到服务器node01、node02、node03服务器上的/kkb/soft路径下
3.每台节点安装下面的2个依赖

sudo yum install -y libtool
sudo yum install -y *unixODBC*

每台节点安装ck服务

cd /kkb/soft/
sudo rpm -ivh  clickhouse*rpm
#注意：请确保soft目录下没有除ClickHouse.rpm结尾以外的rpm结尾的安装包

4.修改配置文件
修改config.xml三台机器都修改配置文件

  # node01
     sudo vim /etc/clickhouse-server/config.xml
   #放开注释的这一行
     <listen_host>::</listen_host>
   #将配置文件拷贝到其他机器上面去
   sudo scp  /etc/clickhouse-server/config.xml  node02:/etc/clickhouse-server/
   sudo scp  /etc/clickhouse-server/config.xml  node03:/etc/clickhouse-server/
  #注意：如果此不报错，则说明第三部操作失败 ，请从第三部重试。

创建metrika.xml

 #node01
   sudo vim /etc/metrika.xml

给予权限

#创建目录 
sudo mkdir  -p  /var/lib/clickhouse/data
sudo  mkdir  -p  /var/lib/clickhouse/metadata
sudo  chmod  -R 777 /var/lib/clickhouse/data
sudo chmod  -R 777 /var/lib/clickhouse/metadata

搭建clickhouse过程中会生成对应的目录
配置文件路径：/etc/clickhouse-server/config.xml
日志文件路径：/var/log/clickhouse-server/
建表信息路径：/data/clickhouse/metadata/
分区数据路径：/data/clickhouse/data/
5.启动ClickHouse启动

sudo service clickhouse-server start
# 命令查看ck是否启动成功
ps -ef | grep clickhouse

连接客户端

clickhouse-client
show databases;

ClickHouse的服务停止
三个节点执行

sudo server clickhouse-server stop

5.命令行客户端连接ClickHouse

clickhouse-client -m -u [username] -h [ip] --password [password] --port [port]  

--user 或者 -u 
用户名。 默认值： default。

--password 
密码。 默认值：空字符串。

--host 或者 -h 
服务端的 host 名称, 默认是 'localhost'

--port
连接的端口，默认值： 9000。

--multiline 或者 -m 
如果指定，允许多行语句查询（Enter 仅代表换行，不代表查询语句完结）。
演示：开启多行查询
 clickhouse-client -m 或者 clickhouse-client -multiline
