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 [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 [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**`0.0.0.0`**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：`/var/lib/clickhouse/` * 日志文件路径：`/var/log/clickhouse-server/clickhouse-server.log` ### 2.4、启动服务 \[root@hallo102 clickhouse-server\]# systemctl start clickhouse-server 或者 \[root@hallo102 clickhouse-server\]# clickhouse start ```bash [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) Active: active (running) since 六 2024-11-16 21:59:16 CST; 3s ago Main PID: 2343 (clckhouse-watch) Tasks: 157 CGroup: /system.slice/clickhouse-server.service ├─2343 clickhouse-watchdog --config=/etc/clickhouse-server/config.xml --pid-file=/run/clickhouse-server/clickhouse-server.pid └─2346 /usr/bin/clickhouse-server --config=/etc/clickhouse-server/config.xml --pid-file=/run/clickhouse-server/clickhouse-server.pid 11月 16 21:59:16 hallo102 systemd[1]: Started ClickHouse Server (analytic DBMS for big data). 11月 16 21:59:16 hallo102 systemd[1]: Starting ClickHouse Server (analytic DBMS for big data)... 11月 16 21:59:17 hallo102 clickhouse-server[2343]: Processing configuration file '/etc/clickhouse-server/config.xml'. 11月 16 21:59:17 hallo102 clickhouse-server[2343]: Logging trace to /var/log/clickhouse-server/clickhouse-server.log 11月 16 21:59:17 hallo102 clickhouse-server[2343]: Logging errors to /var/log/clickhouse-server/clickhouse-server.err.log 11月 16 21:59:17 hallo102 clickhouse-server[2343]: Processing configuration file '/etc/clickhouse-server/config.xml'. 11月 16 21:59:17 hallo102 clickhouse-server[2343]: Saved preprocessed configuration to '/var/lib/clickhouse/preprocessed_configs/config.xml'. 11月 16 21:59:17 hallo102 clickhouse-server[2343]: Processing configuration file '/etc/clickhouse-server/users.xml'. 11月 16 21:59:17 hallo102 clickhouse-server[2343]: Saved preprocessed configuration to '/var/lib/clickhouse/preprocessed_configs/users.xml'. [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 [root@hallo102 clickhouse-server]# clickhouse-client -m ClickHouse client version 21.7.3.14 (official build).
