一、准备工作

1、确定防火墙处于关闭状态

[2、CentOS 取消打开文件数限制](#2、CentOS 取消打开文件数限制)

3、安装依赖

一、准备工作

1、确定防火墙处于关闭状态

bash 复制代码

[root@hallo102 ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
[root@hallo102 ~]#

2、CentOS 取消打开文件数限制

在 /etc/security/limits.conf 文件的末尾加入以下内容

bash 复制代码

* soft nofile 65536 
* hard nofile 65536 
* soft nproc 131072 
* hard nproc 131072

第一列是限制的用户和用户组
soft软限制，hard硬限制
nofile打开文件数，nproc用户进程数

在/etc/security/limits.d/20-nproc.conf文件的末尾加入以下内容

bash 复制代码

* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

退出当前用户，重启登录，ulimit -a查看打开文件数和用户进程数是否更改

$root@hallo102 \~$ # ulimit -a

core file size (blocks, -c) 0

data seg size (kbytes, -d) unlimited

scheduling priority (-e) 0

file size (blocks, -f) unlimited

pending signals (-i) 11687

max locked memory (kbytes, -l) 64

max memory size (kbytes, -m) unlimited
open files (-n) 65536

pipe size (512 bytes, -p) 8

POSIX message queues (bytes, -q) 819200

real-time priority (-r) 0

stack size (kbytes, -s) 8192

cpu time (seconds, -t) unlimited
max user processes (-u) 131072

virtual memory (kbytes, -v) unlimited

file locks (-x) unlimited

$root@hallo102 \~$ #

3、安装依赖

$root@hallo102 \~$ # yum install -y libtool

$root@hallo102 \~$ # yum install -y *unixODBC*

4、CentOS取消SELINUX

$root@hallo102 \~$ # vim /etc/selinux/config

SELINUX=disabled

修改完重启服务器

二、单机安装

官网：https://clickhouse.tech/

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

2.1、下载安装

需要以下四个rpm包：

clickhouse-client-21.7.3.14-2.noarch.rpm

clickhouse-common-static-21.7.3.14-2.x86_64.rpm

clickhouse-common-static-dbg-21.7.3.14-2.x86_64.rpm

clickhouse-server-21.7.3.14-2.noarch.rpm

2.2、安装这4个rpm包

$root@hallo102 clickhouse$ # rpm -ivh *.rpm

bash 复制代码

[root@hallo102 clickhouse]# ll
总用量 938164
-rw-r--r-- 1 root root     78074 11月 16 21:40 clickhouse-client-21.7.3.14-2.noarch.rpm
-rw-r--r-- 1 root root 174283244 11月 16 21:40 clickhouse-common-static-21.7.3.14-2.x86_64.rpm
-rw-r--r-- 1 root root 786208040 11月 16 21:40 clickhouse-common-static-dbg-21.7.3.14-2.x86_64.rpm
-rw-r--r-- 1 root root    101969 11月 16 21:40 clickhouse-server-21.7.3.14-2.noarch.rpm
[root@hallo102 clickhouse]# rpm -ivh *.rpm

2.3、修改配置文件

bash 复制代码

[root@hallo102 clickhouse]# cd /etc/clickhouse-server/
[root@hallo102 clickhouse-server]# chmod 777 config.xml
[root@hallo102 clickhouse-server]# ls
config.d  config.xml  users.d  users.xml
[root@hallo102 clickhouse-server]# 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>/var/lib/clickhouse/</path>
日志文件路径：<log>/var/log/clickhouse-server/clickhouse-server.log</log>

2.4、启动服务

$root@hallo102 clickhouse-server$ # systemctl start clickhouse-server

或者

$root@hallo102 clickhouse-server$ # clickhouse start

bash 复制代码

[root@hallo102 clickhouse-server]# systemctl status clickhouse-server
● clickhouse-server.service - ClickHouse Server (analytic DBMS for big data)
   Loaded: loaded (/etc/systemd/system/clickhouse-server.service; enabled; vendor preset: disabled)

[root@hallo102 clickhouse-server]#

2.5、关闭开机自启

$root@hallo102 clickhouse-server$ # systemctl disable clickhouse-server

Removed symlink /etc/systemd/system/multi-user.target.wants/clickhouse-server.service.

$root@hallo102 clickhouse-server$ #

2.6、使用Client连接server

bash 复制代码

[root@hallo102 clickhouse-server]# clickhouse-client -m
ClickHouse client version 21.7.3.14 (official build).
Connecting to localhost:9000 as user default.
Connected to ClickHouse server version 21.7.3 revision 54449.
