Getting started

=============

|
System requirements
|
|
-----------------
|
|
|
|
This is not a cross-platform system. It requires Linux Ubuntu Precise (12.04) or newer, x86_64 architecture with SSE 4.2 instruction set.
|
|
To test for SSE 4.2 support, do:
|
|
::
|
|
grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
|
|
|
|
We recommend using Ubuntu Trusty or Ubuntu Xenial or Ubuntu Precise.
|
|
The terminal must use UTF-8 encoding (the default in Ubuntu).
|
|
|
|
Installation
|
|
-----------------
|
|
|
|
For testing and development, the system can be installed on a single server or on a desktop computer.
|
|
|
|
Installing from packages
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
In `/etc/apt/sources.list` (or in a separate `/etc/apt/sources.list.d/clickhouse.list` file), add the repository:
|
|
::
|
|
deb http://repo.yandex.ru/clickhouse/trusty stable main
|
|
|
|
For other Ubuntu versions, replace `trusty` to `xenial` or `precise`.
|
|
|
|
Then run:
|
|
::
|
|
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv E0C56BD4 # optional
|
|
sudo apt-get update
|
|
sudo apt-get install clickhouse-client clickhouse-server-common
|
|
|
|
You can also download and install packages manually from here:
|
|
http://repo.yandex.ru/clickhouse/trusty/pool/main/c/clickhouse/,
|
|
http://repo.yandex.ru/clickhouse/xenial/pool/main/c/clickhouse/,
|
|
http://repo.yandex.ru/clickhouse/precise/pool/main/c/clickhouse/.
|
|
|
|
ClickHouse contains access restriction settings. They are located in the 'users.xml' file (next to 'config.xml').
|
|
By default, access is allowed from everywhere for the default user without a password. See 'user/default/networks'. For more information, see the section "Configuration files".
|
|
|
|
Installing from source
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
To build, follow the instructions in build.md (for Linux) or in build_osx.md (for Mac OS X).
|
|
|
|
You can compile packages and install them. You can also use programs without installing packages.
|
|
::
|
|
Client: dbms/src/Client/
|
|
Server: dbms/src/Server/
|
|
|
|
For the server, create a catalog with data, such as:
|
|
::
|
|
/opt/clickhouse/data/default/
|
|
/opt/clickhouse/metadata/default/
|
|
|
|
(Configured in the server config.)
|
|
Run 'chown' for the desired user.
|
|
|
|
Note the path to logs in the server config (src/dbms/src/Server/config.xml).
|
|
|
|
Other methods of installation
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
The Docker image is located here: https://hub.docker.com/r/yandex/clickhouse-server/
|
|
|
|
There is Gentoo overlay located here: https://github.com/kmeaw/clickhouse-overlay
|
|
|
|
|
|
Launch
|
|
-------
|
|
|
|
To start the server (as a daemon), run:
|
|
::
|
|
sudo service clickhouse-server start
|
|
|
|
View the logs in the catalog `/var/log/clickhouse-server/`
|
|
|
|
If the server doesn't start, check the configurations in the file `/etc/clickhouse-server/config.xml`
|
|
|
|
You can also 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'.
|
|
|
|
You can use the command-line client to connect to the server:
|
|
::
|
|
clickhouse-client
|
|
|
|
The default parameters indicate connecting with localhost:9000 on behalf of the user 'default' without a password.
|
|
The client can be used for connecting to a remote server. For example:
|
|
::
|
|
clickhouse-client --host=example.com
|
|
|
|
For more information, see the section "Command-line client".
|
|
|
|
Checking the system:
|
|
::
|
|
milovidov@milovidov-Latitude-E6320:~/work/metrica/src/dbms/src/Client$ ./clickhouse-client
|
|
ClickHouse client version 0.0.18749.
|
|
Connecting to localhost:9000.
|
|
Connected to ClickHouse server version 0.0.18749.

Test data
|
|
---------------
|
|
If you are Yandex employee, you can use Yandex.Metrica test data to explore the system's capabilities. You can find instructions for using the test data here.
|
|
|
|
Otherwise, you could use one of available public datasets, described here.
|
|
|
|
|
|
If you have questions
|
|
---------------------
|
|
If you are Yandex employee, use internal ClickHouse maillist.
|
|
You can subscribe to this list to get announcements, information on new developments, and questions that other users have.
|
|
|
|
Otherwise, you could ask questions on Stack Overflow; discuss in Google Groups; or send private message to developers to address clickhouse-feedback@yandex-team.com.
