一、准备工作
1、确定防火墙处于关闭状态
[root@hallo102 ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemonLoaded: 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
* 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
* 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

[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
[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 *.rpm2.3、修改配置文件
[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
[root@hallo102 clickhouse-server]# systemctl status clickhouse-server

[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
[root@hallo102 clickhouse-server]# clickhouse-client -m
ClickHouse client version 21.7.3.14 (official build).
