Clickhouse 单机版安装

click house单机安装

 

https://clickhouse.tech/docs/en/getting-started/install/
参考官方文档安装方法

系统要求
ClickHouse可以在具有x86_64，AArch64或PowerPC64LE CPU体系结构的任何Linux，FreeBSD或Mac OS X上运行。

帮助文档有DEB包、RPM包、TGZ包、Docker安装。

 

本文以rpm安装方式为例

1、首先检查CPU是否支持SSE 4.2的命令：

[root@host101 mysql]# grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
SSE 4.2 supported ---是支持的

 

2、调整本地运行环境
修改Linux文件打开数限制
在 /etc/security/limits.conf 这个文件的末尾加入一下内容：

vi /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

 

在 /etc/security/limits.d/90-nproc.conf 这个文件的末尾加入一下内容：

vi /etc/security/limits.d/90-nproc.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

 

重启服务器之后生效，用 ulimit -n 或者 ulimit -a 查看设置结果

ulimit -n
ulimit -a

 

关闭selinux
修改 /etc/selinux/config 中的 SELINUX=disabled 后重启

vim /etc/selinux/config
SELINUX=disabled

 

关闭防火墙
CentOS-6 如何操作：

service iptables stop
service ip6tables stop

 

CentOS-7 如何操作：

systemctl status firewalld.service
systemctl stop firewalld.service
systemctl start firewalld.service

 

3、安装

yum install yum-util -y
rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64
yum install clickhouse-server clickhouse-client -y

 

因为网络的原因，yum安装网络一直失败，
可以选择离线安装，先手动下载rpm包，下载到本地再上传到服务器
下载地址：

https://repo.clickhouse.tech/rpm/stable/x86_64

 

下载这三个文件
clickhouse-server-20.5.4.40-2.noarch.rpm 
clickhouse-common-static-20.5.4.40-2.x86_64.rpm 
clickhouse-client-20.5.4.40-2.noarch.rpm
