Install ClickHouse

You have three options for getting up and running with ClickHouse:

  • ClickHouse Cloud: The official ClickHouse as a service, - built by, maintained and supported by the creators of ClickHouse
  • Quick Install: an easy-to-download binary for testing and developing with ClickHouse
  • Production Deployments: ClickHouse can run on any Linux, FreeBSD, or macOS with x86-64, ARM, or PowerPC64LE CPU architecture
  • Docker Image: use the official Docker image in Docker Hub

ClickHouse Cloud​

The quickest and easiest way to get up and running with ClickHouse is to create a new service in ClickHouse Cloud.

Quick Install​

tip

For production installs of a specific release version see the installation options down below.

On Linux, macOS and FreeBSD:

  1. If you are just getting started and want to see what ClickHouse can do, the simplest way to download ClickHouse locally is to run the following command. It downloads a single binary for your operating system that can be used to run the ClickHouse server, clickhouse-client, clickhouse-local, ClickHouse Keeper, and other tools:

    curl https://clickhouse.com/ | sh

  2. Run the following command to start the ClickHouse server:

    ./clickhouse server

    The first time you run this script, the necessary files and folders are created in the current directory, then the server starts.

  3. Open a new terminal and use the ./clickhouse client to connect to your service:

    ./clickhouse client
    ./clickhouse client
    ClickHouse client version 23.2.1.1501 (official build).
    Connecting to localhost:9000 as user default.
    Connected to ClickHouse server version 23.2.1 revision 54461.

    local-host :)

    You are ready to start sending DDL and SQL commands to ClickHouse!

tip

The Quick Start walks through the steps for creating tables and inserting data.

Production Deployments​

For production deployments of ClickHouse, choose from one of the following install options.

From DEB Packages​

It is recommended to use official pre-compiled deb packages for Debian or Ubuntu. Run these commands to install packages:

Setup the Debian repository​

sudo apt-get install -y apt-transport-https ca-certificates dirmngr
GNUPGHOME=$(mktemp -d)
sudo GNUPGHOME="$GNUPGHOME" gpg --no-default-keyring --keyring /usr/share/keyrings/clickhouse-keyring.gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 8919F6BD2B48D754
sudo rm -r "$GNUPGHOME"
sudo chmod +r /usr/share/keyrings/clickhouse-keyring.gpg

echo "deb [signed-by=/usr/share/keyrings/clickhouse-keyring.gpg] https://packages.clickhouse.com/deb stable main" | sudo tee \
    /etc/apt/sources.list.d/clickhouse.list
sudo apt-get update

Install ClickHouse server and client​

sudo apt-get install -y clickhouse-server clickhouse-client

Start ClickHouse server​

sudo service clickhouse-server start
clickhouse-client # or "clickhouse-client --password" if you've set up a password.
Deprecated Method for installing deb-packages
sudo apt-get install apt-transport-https ca-certificates dirmngr
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv E0C56BD4

echo "deb https://repo.clickhouse.com/deb/stable/ main/" | sudo tee \
    /etc/apt/sources.list.d/clickhouse.list
sudo apt-get update

sudo apt-get install -y clickhouse-server clickhouse-client

sudo service clickhouse-server start
clickhouse-client # or "clickhouse-client --password" if you set up a password.
Migration Method for installing the deb-packages
sudo apt-key del E0C56BD4
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 8919F6BD2B48D754
echo "deb https://packages.clickhouse.com/deb stable main" | sudo tee \
    /etc/apt/sources.list.d/clickhouse.list
sudo apt-get update

sudo apt-get install -y clickhouse-server clickhouse-client

sudo service clickhouse-server start
clickhouse-client # or "clickhouse-client --password" if you set up a password.

You can replace stable with lts to use different release kinds based on your needs.

You can also download and install packages manually from here.

Install standalone ClickHouse Keeper​

tip

In production environment we strongly recommend running ClickHouse Keeper on dedicated nodes. In test environments, if you decide to run ClickHouse Server and ClickHouse Keeper on the same server, you do not need to install ClickHouse Keeper as it is included with ClickHouse server. This command is only needed on standalone ClickHouse Keeper servers.

sudo apt-get install -y clickhouse-keeper

Enable and start ClickHouse Keeper​

sudo systemctl enable clickhouse-keeper
sudo systemctl start clickhouse-keeper
sudo systemctl status clickhouse-keeper

Packages​

  • clickhouse-common-static — Installs ClickHouse compiled binary files.
  • clickhouse-server — Creates a symbolic link for clickhouse-server and installs the default server configuration.
  • clickhouse-client — Creates a symbolic link for clickhouse-client and other client-related tools. and installs client configuration files.
  • clickhouse-common-static-dbg — Installs ClickHouse compiled binary files with debug info.
  • clickhouse-keeper - Used to install ClickHouse Keeper on dedicated ClickHouse Keeper nodes. If you are running ClickHouse Keeper on the same server as ClickHouse server, then you do not need to install this package. Installs ClickHouse Keeper and the default ClickHouse Keeper configuration files.
info

If you need to install specific version of ClickHouse you have to install all packages with the same version: sudo apt-get install clickhouse-server=21.8.5.7 clickhouse-client=21.8.5.7 clickhouse-common-static=21.8.5.7

From RPM Packages​

It is recommended to use official pre-compiled rpm packages for CentOS, RedHat, and all other rpm-based Linux distributions.

Setup the RPM repository​

First, you need to add the official repository:

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://packages.clickhouse.com/rpm/clickhouse.repo

For systems with zypper package manager (openSUSE, SLES):

sudo zypper addrepo -r https://packages.clickhouse.com/rpm/clickhouse.repo -g
sudo zypper --gpg-auto-import-keys refresh clickhouse-stable

Later any yum install can be replaced by zypper install. To specify a particular version, add -$VERSION to the end of the package name, e.g. clickhouse-client-22.2.2.22.

Install ClickHouse server and client​

sudo yum install -y clickhouse-server clickhouse-client

Start ClickHouse server​

sudo systemctl enable clickhouse-server
sudo systemctl start clickhouse-server
sudo systemctl status clickhouse-server
clickhouse-client # or "clickhouse-client --password" if you set up a password.

Install standalone ClickHouse Keeper​

tip

In production environment we strongly recommend running ClickHouse Keeper on dedicated nodes. In test environments, if you decide to run ClickHouse Server and ClickHouse Keeper on the same server, you do not need to install ClickHouse Keeper as it is included with ClickHouse server. This command is only needed on standalone ClickHouse Keeper servers.

sudo yum install -y clickhouse-keeper

Enable and start ClickHouse Keeper​

sudo systemctl enable clickhouse-keeper
sudo systemctl start clickhouse-keeper
sudo systemctl status clickhouse-keeper
Deprecated Method for installing rpm-packages
sudo yum install yum-utils
sudo rpm --import https://repo.clickhouse.com/CLICKHOUSE-KEY.GPG
sudo yum-config-manager --add-repo https://repo.clickhouse.com/rpm/clickhouse.repo
sudo yum install clickhouse-server clickhouse-client

sudo /etc/init.d/clickhouse-server start
clickhouse-client # or "clickhouse-client --password" if you set up a password.

You can replace stable with lts to use different release kinds based on your needs.

Then run these commands to install packages:

sudo yum install clickhouse-server clickhouse-client

You can also download and install packages manually from here.

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://packages.clickhouse.com/tgz/. After that downloaded archives should be unpacked and installed with installation scripts. Example for the latest stable version:

LATEST_VERSION=$(curl -s https://packages.clickhouse.com/tgz/stable/ | \
    grep -Eo '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' | sort -V -r | head -n 1)
export LATEST_VERSION

case $(uname -m) in
  x86_64) ARCH=amd64 ;;
  aarch64) ARCH=arm64 ;;
  *) echo "Unknown architecture $(uname -m)"; exit 1 ;;
esac

for PKG in clickhouse-common-static clickhouse-common-static-dbg clickhouse-server clickhouse-client clickhouse-keeper
do
  curl -fO "https://packages.clickhouse.com/tgz/stable/$PKG-$LATEST_VERSION-${ARCH}.tgz" \
    || curl -fO "https://packages.clickhouse.com/tgz/stable/$PKG-$LATEST_VERSION.tgz"
done

tar -xzvf "clickhouse-common-static-$LATEST_VERSION-${ARCH}.tgz" \
  || tar -xzvf "clickhouse-common-static-$LATEST_VERSION.tgz"
sudo "clickhouse-common-static-$LATEST_VERSION/install/doinst.sh"

tar -xzvf "clickhouse-common-static-dbg-$LATEST_VERSION-${ARCH}.tgz" \
  || tar -xzvf "clickhouse-common-static-dbg-$LATEST_VERSION.tgz"
sudo "clickhouse-common-static-dbg-$LATEST_VERSION/install/doinst.sh"

tar -xzvf "clickhouse-server-$LATEST_VERSION-${ARCH}.tgz" \
  || tar -xzvf "clickhouse-server-$LATEST_VERSION.tgz"
sudo "clickhouse-server-$LATEST_VERSION/install/doinst.sh" configure
sudo /etc/init.d/clickhouse-server start

tar -xzvf "clickhouse-client-$LATEST_VERSION-${ARCH}.tgz" \
  || tar -xzvf "clickhouse-client-$LATEST_VERSION.tgz"
sudo "clickhouse-client-$LATEST_VERSION/install/doinst.sh"
Deprecated Method for installing tgz archives
export LATEST_VERSION=$(curl -s https://repo.clickhouse.com/tgz/stable/ | \
    grep -Eo '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+' | sort -V -r | head -n 1)
curl -O https://repo.clickhouse.com/tgz/stable/clickhouse-common-static-$LATEST_VERSION.tgz
curl -O https://repo.clickhouse.com/tgz/stable/clickhouse-common-static-dbg-$LATEST_VERSION.tgz
curl -O https://repo.clickhouse.com/tgz/stable/clickhouse-server-$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.

Non-Production Deployments (Advanced)​

Compile From Source​

To manually compile ClickHouse, follow the instructions for Linux or macOS.

You can compile packages and install them or use programs without installing packages.

  Client: <build_directory>/programs/clickhouse-client
  Server: <build_directory>/programs/clickhouse-server

You’ll need to create data and metadata folders manually and chown them for the desired user. Their paths can be changed in server config (src/programs/server/config.xml), by default they are:

  /var/lib/clickhouse/data/default/
  /var/lib/clickhouse/metadata/default/

On Gentoo, you can just use emerge clickhouse to install ClickHouse from sources.

Install a CI-generated Binary​

ClickHouse's continuous integration (CI) infrastructure produces specialized builds for each commit in the ClickHouse repository, e.g. sanitized builds, unoptimized (Debug) builds, cross-compiled builds etc. While such builds are normally only useful during development, they can in certain situations also be interesting for users.

note

Since ClickHouse's CI is evolving over time, the exact steps to download CI-generated builds may vary. Also, CI may delete too old build artifacts, making them unavailable for download.

For example, to download a aarch64 binary for ClickHouse v23.4, follow these steps:

  • Find the GitHub pull request for release v23.4: Release pull request for branch 23.4
  • Click "Commits", then click a commit similar to "Update autogenerated version to 23.4.2.1 and contributors" for the particular version you like to install.
  • Click the green check / yellow dot / red cross to open the list of CI checks.
  • Click "Details" next to "ClickHouse Build Check" in the list, it will open a page similar to this page
  • Find the rows with compiler = "clang-*-aarch64" - there are multiple rows.
  • Download the artifacts for these builds.

To download binaries for very old x86-64 systems without SSE3 support or old ARM systems without ARMv8.1-A support, open a pull request and find CI check "BuilderBinAmd64Compat", respectively "BuilderBinAarch64V80Compat". Then click "Details", open the "Build" fold, scroll to the end, find message "Notice: Build URLs https://s3.amazonaws.com/clickhouse/builds/PRs/.../.../binary_aarch64_v80compat/clickhouse". You can then click the link to download the build.

macOS-only: Install with Homebrew​

To install ClickHouse using the popular brew package manager, follow the instructions listed in the ClickHouse Homebrew tap.

Launch​

To start the server as a daemon, run:

$ sudo clickhouse start

There are also other ways to run ClickHouse:

$ sudo service clickhouse-server start

If you do not have service command, run as

$ sudo /etc/init.d/clickhouse-server start

If you have systemctl command, run as

$ sudo systemctl start clickhouse-server.service

See the logs in the /var/log/clickhouse-server/ directory.

If the server does not 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 do not 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.

:) SELECT 1

SELECT 1

┌─1─┐
│ 1 │
└───┘

1 rows in set. Elapsed: 0.003 sec.

:)

Congratulations, the system works!

To continue experimenting, you can download one of the test data sets or go through tutorial.

Recommendations for Self-Managed ClickHouse​

ClickHouse can run on any Linux, FreeBSD, or macOS with x86-64, ARM, or PowerPC64LE CPU architecture.

ClickHouse uses all hardware resources available to process data.

ClickHouse tends to work more efficiently with a large number of cores at a lower clock rate than with fewer cores at a higher clock rate.

We recommend using a minimum of 4GB of RAM to perform non-trivial queries. The ClickHouse server can run with a much smaller amount of RAM, but queries will then frequently abort.

The required volume of RAM generally depends on:

  • The complexity of queries.
  • The amount of data that is processed in queries.

To calculate the required volume of RAM, you may estimate the size of temporary data for GROUP BY, DISTINCT, JOIN and other operations you use.

To reduce memory consumption, ClickHouse can swap temporary data to external storage. See GROUP BY in External Memory for details.

We recommend to disable the operating system's swap file in production environments.

The ClickHouse binary requires at least 2.5 GB of disk space for installation.

The volume of storage required for your data may be calculated separately based on

  • an estimation of the data volume.

    You can take a sample of the data and get the average size of a row from it. Then multiply the value by the number of rows you plan to store.

  • The data compression coefficient.

    To estimate the data compression coefficient, load a sample of your data into ClickHouse, and compare the actual size of the data with the size of the table stored. For example, clickstream data is usually compressed by 6-10 times.

To calculate the final volume of data to be stored, apply the compression coefficient to the estimated data volume. If you plan to store data in several replicas, then multiply the estimated volume by the number of replicas.

For distributed ClickHouse deployments (clustering), we recommend at least 10G class network connectivity.

Network bandwidth is critical for processing distributed queries with a large amount of intermediate data. Besides, network speed affects replication processes.
