clickhouse安装配置

一、介绍

Clickhouse是一个用于联机分析处理（OLAP）的列式数据库管理系统（columnar DBMS），并允许使用SQL查询实时生成分析报告。

二、clickhouse安装

1. 配置源

vim /etc/yum.repos.d/clickhouse.repo

[altinity_clickhouse]name=altinity_clickhousebaseurl=https://packagecloud.io/altinity/clickhouse/el/7/$basearchrepo_gpgcheck=1gpgcheck=0enabled=1gpgkey=https://packagecloud.io/altinity/clickhouse/gpgkeysslverify=1sslcacert=/etc/pki/tls/certs/ca-bundle.crtmetadata_expire=300[altinity_clickhouse-source]name=altinity_clickhouse-sourcebaseurl=https://packagecloud.io/altinity/clickhouse/el/7/SRPMSrepo_gpgcheck=1gpgcheck=0enabled=1gpgkey=https://packagecloud.io/altinity/clickhouse/gpgkeysslverify=1sslcacert=/etc/pki/tls/certs/ca-bundle.crtmetadata_expire=300

2. clickhouse安装

yum makecache
yum install -y clickhouse-server clickhouse-client

3. 修改配置

vim /etc/clickhouse-server/config.xml

#修改log路径<log>/data/clickhouse/logs/clickhouse-server.log</log><errorlog>/data/clickhouse/logs/clickhouse-server.err.log</errorlog>#http端口<http_port>8123</http_port>#tcp端口<tcp_port>9000</tcp_port>#副本同步端口<interserver_http_port>9009</interserver_http_port>#主机名<interserver_http_host>clickhouse </interserver_http_host>#监听地址<listen_host>::</listen_host>#数据目录<path>/data/clickhouse/data</path>#临时文件路径<tmp_path>/data/clickhouse/tmp/</tmp_path>#用户定义文件路径<user_files_path>/data/clickhouse/user_files/</user_files_path><users_config>users.xml</users_config>

4. 生成密码

PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'

5. 配置用户

vim /etc/clickhouse-server/users.xml

<test><password_sha256_hex>6de608c69f21b017a6148f31cfae59aa0cc1e5abfc174c752b0c0abfd3274936</password_sha256_hex><networks incl="networks" replace="replace"><ip>::/0</ip>
    </networks>
    <profile>default</profile>
    <quota>default</quota>
    <allow_databases>
      <database>test</database>
    </allow_databases></test> <readonly>
    <password></password>
    <networks incl="networks" replace="replace">
        <ip>::1</ip>
         <ip>127.0.0.1</ip>
     </networks>
     <profile>readonly</profile>
     <quota>default</quota></readonly>

6. 启动服务

/etc/init.d/clickhouse-server start

7. 验证

clickhouse-client -utest --password $PASSWORD
clickhouse安装配置

三、集群配置

1. 修改配置文件

vim /etc/clickhouse-server/config.xml

#添加<include_from>/etc/clickhouse-server/metrika.xml</include_from>

2. 集群配置

vim /etc/clickhouse-server/metrika.xml
