1.安裝clickhouse環境

ClickHouse對Debian/Ubuntu支持較好，但是工作當中服務器我們一般用CentOs。今天我們使用CentOs7來安裝一下ClickHouse。
操作系統版本：CentOS Linux release 7.5.1804 (Core)

檢查一下是否支持SSE 4.2指令集:

grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"

2.下載安裝包

下載地址：

https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/ 下載一下四個包： clickhouse-client-18.12.17-2.noarch.rpm clickhouse-server-common-18.12.17-2.noarch.rpm clickhouse-server-18.12.17-2.noarch.rpm clickhouse-client-18.12.17-2.noarch.rpm

開始安裝：

rpm -ivh clickhouse-server-common-18.12.17-2.noarch.rpm rpm -ivh clickhouse-server-18.12.17-2.noarch.rpm rpm -ivh clickhouse-common-static-18.12.17-2.x86_64.rpm rpm -ivh clickhouse-client-18.12.17-2.noarch.rpm

注意：在安裝第二步會出現依賴錯誤，需下載依賴，yum install ODBC
再次安裝clickhouse-server沒問題了。
安裝后配置路徑：cd /etc/clickhouse-server/

啟動命令：

clickhouse-server --config-file=/etc/clickhouse-server/config.xml 或： systemctl stop clickhouse-server systemctl start clickhouse-server

3.clickhouse配置

放開遠程訪問：
vi /etc/clickhouse-server/config.xml
修改服務器的配置文件/etc/clickhouse-server/config.xml，第65行，放開注釋即可，修改之后的內容如下：

<listen_host>::</listen_host> <listen_host>127.0.0.1</listen_host>

內存權限設置：
vi /etc/clickhouse-server/users.xml

<default><!-- Maximum memory usage for processing single query, in bytes. --><max_memory_usage>26800000000</max_memory_usage><!-- Use cache of uncompressed blocks of data. Meaningfu

4.本地客戶端使用clickhouse-client

啟動客戶端命令：

#clickhouse-client

創建數據庫：(遵循mysql創建語句)

CREATE DATABASE [ IF NOT EXISTS ] db_name

創建數據表：(末尾需要增加表引擎)

CREATE TABLE F_SZ_RYXX (PERSON_ID String,NBXH String,NAME String,CERTYPE String,BLICTYPE String,CERNO String,HJSZD String,SEX String,AGE Decimal (18,0),RZQX Decimal (18,0),NATDATE Date,DOM String,TEL String,LITDEG String,OFFSIGN String,ACCDSIDE String,COUNTRY String,STUFFTYPE String,POSITION String,POSBRFORM String,APPOUNIT String,SJC Date,RJZB Decimal (18,0),TZE Decimal (18,0),CZFS String,SJZB Decimal (18,0),SJCZFS String,CZRQ Date,CZBL Decimal (18,0),CZF String,TZRLX String,SFBD Decimal (18,0),SFLDRKHYZM Decimal (18,0),ZXHHSWBZ String,RYLX String,FZJG String,SJQK String,BFB Decimal (18,0),UNISCID String,ZCH String,QYMC String,DJJG String,FDDBR String,CLRQ Date,QYLX String,QYSX String,JYZT String,ZCZB Decimal (18,0) ) ENGINE = MergeTree(CLRQ,(PERSON_ID),10);

插入數據
A: 通過insert into 語句插入：(字符串需要單引號才能插入)

insert into f_sz_ryxx (PERSON_ID,NBXH,NAME,CERTYPE,BLICTYPE,CERNO,HJSZD,SEX,AGE,RZQX,NATDATE,DOM,TEL,LITDEG,OFFSIGN,ACCDSIDE,COUNTRY,STUFFTYPE,POSITION,POSBRFORM,APPOUNIT,SJC,RJZB,TZE,CZFS,SJZB,SJCZFS,CZRQ,CZBL,CZF,TZRLX,SFBD,SFLDRKHYZM,ZXHHSWBZ,RYLX,FZJG,SJQK,BFB,UNISCID,ZCH,QYMC,DJJG,FDDBR,CLRQ,QYLX,QYSX,JYZT,ZCZB) values('2140000000171339','2140000000014007','王民','10','','142701570501001','','1','61','','1/5/1957 00:00:00','太原市迎澤區東安路7－3－17','13835178783','','0','','156','02','','03','','19/2/2001 00:00:00','','','','','','','','','','','','','1','','','','','1400002002070','山西皮爾復臨床醫藥開發有限公司','1400000000','王民','1/9/1992 00:00:00','1130','03','11','300');

B: 導入csv文件數據：

cat F_SZ_RYXX.csv | clickhouse-client --query="INSERT INTO f_sz_ryxx FORMAT CSV"

C: mysql數據導入clickhouse

#du出的表大小 5.5G article_clientuser_sum.ibd#ClickHouse操作語句CREATE TABLE article_clientuser_sumENGINE = MergeTreeORDER BY id ASSELECT *FROM mysql('host:port', 'db', 'article_clientuser_sum', 'user', 'password') #耗時和平均速度0 rows in set.

5 clickhouse-mysql安裝及數據實時插入

在CentOS 7上測試

來自packagecloud.io的 Packagecloud repo 有關安裝的更多詳細信息，請訪問https://github.com/Altinity/clickhouse-rpm-install

curl -s https://packagecloud.io/install/repositories/altinity/clickhouse/script.rpm.sh | sudo bash

安裝EPEL（for python3）和MySQL（for libmysqlclient）repos

sudo yum install -y epel-release sudo yum install -y https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

如果您的回購中沒有EPEL，請直接從EPEL網站安裝

sudo yum install -y https://download.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

從packagecloud.io安裝數據閱讀器

sudo yum install -y clickhouse-mysql

clickhouse包也將作為依賴項安裝。
準備配置文件 - 將示例文件復制到生產環境中并進行編輯。

sudo cp /etc/clickhouse-mysql/clickhouse-mysql-example.conf /etc/clickhouse-mysql/clickhouse-mysql.conf sudo vim /etc/clickhouse-mysql/clickhouse-mysql.conf

連接mysql-clickhouse數據插入

clickhouse-mysql \ --src-server-id=1 \ --src-resume \ --src-wait \ --nice-pause=1 \ --src-host=192.168.3.191 \ --src-user=root \ --src-password=abcd@1234 \ --src-tables=ZHIXIAOQIYE.zhixiao_data \ --dst-host=192.168.3.194 \ --dst-schema=default \ # 指定clickhouse數據庫 --dst-table=zhixiao \ # 指定clickhouse數據表 --csvpool \ --csvpool-file-path-prefix=qwe_ \ --mempool-max-flush-interval=60 \ --mempool-max-events-num=10000

6 clickhouse客戶端連接

clickhouse-client -h 192.168.3.194 --port 9001
