一.下载安装介质及安装

1.1 下载

官网：https://clickhouse.tech/

下载地址：https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/

需要以下四个rpm包：

cd /usr/local/src
mkdir ck
cd ck
wget https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/clickhouse-client-22.2.2.1-2.noarch.rpm
wget https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/clickhouse-common-static-22.2.2.1-2.x86_64.rpm
wget https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/clickhouse-common-static-dbg-22.2.2.1-2.x86_64.rpm
wget https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/clickhouse-server-22.2.2.1-2.noarch.rpm

1.2 安装

安装前需要关闭防火墙和SELinux

取消打开文件限制

vim /etc/security/limits.conf
*   soft nofile 65536
*   hard nofile 65536
*   soft nproc 131072
*   hard nproc 131072

vim /etc/security/limits.d/20-nproc.conf
*   soft nofile 65536
*   hard nofile 65536
*   soft nproc 131072
*   hard nproc 131072

安装依赖

yum install -y libtool

安装

cd /usr/local/src/ck
rpm -ivh *.rpm

二. 修改配置文件

cd /etc/clickhouse-server/
chmod 777 config.xml 
vim config.xml 

把<listen_host>0.0.0.0</listen_host>的注释打开，这样的话才能让ClickHouse被除本机之外的服务器访问

这个配置文件中，ClickHouse一些默认路径配置：

数据文件路径：<path>/home/ckdata/</path>
日志文件路径：<log>/home/cklog/clickhouse-server.log</log>

mkdir -p /home/ckdata
mkdir -p /home/cklog
chmod -R 777 /home/ckdata
chmod -R 777 /home/cklog

三. 启动Server

3.1 启动Server

systemctl start clickhouse-server
or
clickhouse start

3.2 关闭开启自启

systemctl disable clickhouse-server

3.3 使用Client连接server

命令:

clickhouse-client -m --password

测试记录:

[root@hp5 clickhouse-server]# clickhouse-client -m --password
ClickHouse client version 22.2.2.1.
Password for user (default): 
Connecting to localhost:9000 as user default.
Connected to ClickHouse server version 22.2.2 revision 54455.

Warnings:
 * Effective user of the process (clickhouse) does not match the owner of the data (root).
