Installation
System Requirements
ClickHouse can run on any Linux, FreeBSD, or Mac OS X with x86_64, AArch64, or PowerPC64LE CPU architecture.
Official pre-built binaries are typically compiled for x86_64 and leverage SSE 4.2 instruction set, so unless otherwise stated usage of CPU that supports it becomes an additional system requirement. Here’s the command to check if current CPU has support for SSE 4.2:
$ grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
To run ClickHouse on processors that do not support SSE 4.2 or have AArch64 or PowerPC64LE architecture, you should build ClickHouse from sources with proper configuration adjustments.
Available Installation Options
From DEB Packages
It is recommended to use official pre-compiled deb packages for Debian or Ubuntu.
To install official packages add the Yandex repository in /etc/apt/sources.list or in a separate /etc/apt/sources.list.d/clickhouse.list file:
deb http://repo.clickhouse.tech/deb/stable/ main/
If you want to use the most recent version, replace stable with testing (this is recommended for your testing environments).
Then run these commands to install packages:
sudo apt-get install dirmngr # optional
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv E0C56BD4 # optional
sudo apt-get update
sudo apt-get install clickhouse-client clickhouse-server
You can also download and install packages manually from here: https://repo.yandex.ru/clickhouse/deb/stable/main/.
Packages
clickhouse-common-static— Installs ClickHouse compiled binary files.clickhouse-server— Creates a symbolic link forclickhouse-serverand installs the default server configuration.clickhouse-client— Creates a symbolic link forclickhouse-clientand other client-related tools. and installs client configuration files.clickhouse-common-static-dbg— Installs ClickHouse compiled binary files with debug info.
From RPM Packages
It is recommended to use official pre-compiled rpm packages for CentOS, RedHat, and all other rpm-based Linux distributions.
First, you need to add the official repository:
sudo yum install yum-utils
sudo rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
sudo yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64
If you want to use the most recent version, replace stable with testing (this is recommended for your testing environments). The prestable tag is sometimes available too.
Then run these commands to install packages:
sudo yum install clickhouse-server clickhouse-client
You can also download and install packages manually from here: https://repo.clickhouse.tech/rpm/stable/x86_64.
From tgz archives
It is recommended to use official pre-compiled tgz archives for all Linux distributions, where installation of deb or rpm packages is not possible.
The required version can be downloaded with curl or wget from repository https://repo.yandex.ru/clickhouse/tgz/.
After that downloaded archives should be unpacked and installed with installation scripts. Example for the latest version:
export LATEST_VERSION=`curl https://api.github.com/repos/ClickHouse/ClickHouse/tags 2>/dev/null | grep -Eo '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' | head -n 1`
curl -O https://repo.clickhouse.tech/tgz/clickhouse-common-static-$LATEST_VERSION.tgz
curl -O https://repo.clickhouse.tech/tgz/clickhouse-common-static-dbg-$LATEST_VERSION.tgz
curl -O https://repo.clickhouse.tech/tgz/clickhouse-server-$LATEST_VERSION.tgz
curl -O https://repo.clickhouse.tech/tgz/clickhouse-client-$LATEST_VERSION.tgz
tar -xzvf clickhouse-common-static-$LATEST_VERSION.tgz
sudo clickhouse-common-static-$LATEST_VERSION/install/doinst.sh
tar -xzvf clickhouse-common-static-dbg-$LATEST_VERSION.tgz
sudo clickhouse-common-static-dbg-$LATEST_VERSION/install/doinst.sh
tar -xzvf clickhouse-server-$LATEST_VERSION.tgz
sudo clickhouse-server-$LATEST_VERSION/install/doinst.sh
sudo /etc/init.d/clickhouse-server start
tar -xzvf clickhouse-client-$LATEST_VERSION.tgz
sudo clickhouse-client-$LATEST_VERSION/install/doinst.sh
For production environments, it’s recommended to use the latest stable-version. You can find its number on GitHub page https://github.com/ClickHouse/ClickHouse/tags with postfix -stable.
From Docker Image
To run ClickHouse inside Docker follow the guide on Docker Hub. Those images use official deb packages inside.
From Sources
To manually compile ClickHouse, follow the instructions for Linux or Mac OS X.
You can compile packages and install them or use programs without installing packages. Also by building manually you can disable SSE 4.2 requirement or build for AArch64 CPUs.
Client: programs/clickhouse-client
Server: programs/clickhouse-server
You’ll need to create a data and metadata folders and chown them for the desired user. Their paths can be changed in server config (src/programs/server/config.xml), by default they are:
/opt/clickhouse/data/default/
/opt/clickhouse/metadata/default/
On Gentoo, you can just use emerge clickhouse to install ClickHouse from sources.
Launch
To start the server as a daemon, run:
$ sudo service clickhouse-server start
If you don’t have service command, run as
$ sudo /etc/init.d/clickhouse-server start
See the logs in the /var/log/clickhouse-server/ directory.
If the server doesn’t start, check the configurations in the file /etc/clickhouse-server/config.xml.
You can also manually launch the server from the console:
$ clickhouse-server --config-file=/etc/clickhouse-server/config.xml
In this case, the log will be printed to the console, which is convenient during development.
If the configuration file is in the current directory, you don’t need to specify the --config-file parameter. By default, it uses ./config.xml.
ClickHouse supports access restriction settings. They are located in the users.xml file (next to config.xml).
By default, access is allowed from anywhere for the default user, without a password. See user/default/networks.
For more information, see the section “Configuration Files”.
After launching server, you can use the command-line client to connect to it:
$ clickhouse-client
By default, it connects to localhost:9000 on behalf of the user default without a password. It can also be used to connect to a remote server using --host argument.
The terminal must use UTF-8 encoding. For more information, see the section “Command-line client”.
Example:
$ ./clickhouse-client
ClickHouse client version 0.0.18749.
Connecting to localhost:9000.
Connected to ClickHouse server version 0.0.18749.
