Getting Started
System Requirements
This is not a cross-platform system. It requires Linux Ubuntu Precise (12.04) or newer, with x86_64 architecture and support for the SSE 4.2 instruction set. To check for SSE 4.2:
grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
We recommend using Ubuntu Trusty, 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 for Debian/Ubuntu
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/deb/stable/ main/
If you want to use the most recent test version, replace 'stable' with 'testing'.
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
You can also download and install packages manually from here: https://repo.yandex.ru/clickhouse/deb/stable/main/.
ClickHouse contains 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".
Installing from Sources
To compile, follow the instructions: build.md
You can compile packages and install them. You can also use programs without installing packages.
Client: dbms/programs/clickhouse-client
Server: dbms/programs/clickhouse-server
For the server, create a catalog with data, such as:
/opt/clickhouse/data/default/
/opt/clickhouse/metadata/default/
(Configurable in the server config.) Run 'chown' for the desired user.
Note the path to logs in the server config (src/dbms/programs/config.xml).
Other Installation Methods
Docker image: https://hub.docker.com/r/yandex/clickhouse-server/
RPM packages for CentOS or RHEL: https://github.com/Altinity/clickhouse-rpm-install
Gentoo: emerge clickhouse
Launch
To start the server (as a daemon), run:
sudo service 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 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. Example:
clickhouse-client --host=example.com
For more information, see the section "Command-line client".
Checking the system:
milovidov@hostname:~/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.

Congratulations, the system works!
