ClickHouse can run on any Linux, FreeBSD or Mac OS X with x86_64 CPU architecture.
Though pre-built binaries are typically compiled to 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"
From DEB Packages¶
Yandex ClickHouse team recommends using 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
deb http://repo.yandex.ru/clickhouse/deb/stable/ main/
If you want to use the most recent version, replace
testing (this is not recommended for production environments).
Then run these commands to actually install packages:
sudo apt-key adv --keyserver keyserver.ubuntu.com --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/.
From RPM Packages¶
Yandex does not run ClickHouse on
rpm based Linux distributions and
rpm packages are not as thoroughly tested. So use them at your own risk, but there are many other companies that do successfully run them in production without any major issues.
For CentOS, RHEL or Fedora there are the following options:
- Packages from https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/ are generated from official
debpackages by Yandex and have byte-identical binaries.
- Packages from https://github.com/Altinity/clickhouse-rpm-install are built by independent company Altinity, but are used widely without any complaints.
- Or you can use Docker (see below).
From Docker Image¶
To run ClickHouse inside Docker follow the guide on Docker Hub. Those images use official
deb packages inside.
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: dbms/programs/clickhouse-client Server: dbms/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/dbms/programs/server/config.xml), by default they are:
On Gentoo you can just use
emerge clickhouse to install ClickHouse from sources.
To start the server as a daemon, run:
$ sudo service clickhouse-server start
See the logs in the
If the server doesn't start, check the configurations in the file
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
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:
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
The terminal must use UTF-8 encoding. For more information, see the section "Command-line client".
$ ./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!
