# Getting Started
|
|
|
|
## System Requirements
|
|
|
|
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:
|
|
|
|
``` bash
|
|
$ grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"
|
|
```
|
|
|
|
## Installation
|
|
|
|
### 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 `/etc/apt/sources.list.d/clickhouse.list` file:
|
|
|
|
```bash
|
|
$ deb http://repo.yandex.ru/clickhouse/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 actually install packages:
|
|
|
|
```bash
|
|
$ 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/>.
|
|
|
|
### From RPM Packages
|
|
|
|
Yandex ClickHouse team recommends using official pre-compiled `rpm` packages for CentOS, RedHat and all other rpm-based Linux distributions.
|
|
|
|
First you need to add the official repository:
|
|
|
|
```bash
|
|
$ sudo yum install yum-utils
|
|
$ sudo rpm --import https://repo.yandex.ru/clickhouse/CLICKHOUSE-KEY.GPG
|
|
$ sudo yum-config-manager --add-repo https://repo.yandex.ru/clickhouse/rpm/stable/x86_64
|
|
```
|
|
|
|
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 actually install packages:
|
|
|
|
```bash
|
|
$ sudo yum install clickhouse-server clickhouse-client
|
|
```
|
|
|
|
You can also download and install packages manually from here: <https://repo.yandex.ru/clickhouse/rpm/stable/x86_64>.
|
|
|
|
### From Docker Image
|
|
|
|
To run ClickHouse inside Docker follow the guide on [Docker Hub](https://hub.docker.com/r/yandex/clickhouse-server/). Those images use official `deb` packages inside.
|
|
|
|
### From Sources
|
|
|
|
To manually compile ClickHouse, follow the instructions for [Linux](../development/build.md) or [Mac OS X](../development/build_osx.md).
|
|
|
|
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.
|
|
|
|
```text
|
|
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:
|
|
```text
|
|
/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:
|
|
|
|
``` bash
|
|
$ sudo service clickhouse-server start
|
|
```
|
|
|
|
If you don't have `service` command, run as
|
|
|
|
``` bash
|
|
$ 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:
|
|
|
|
``` bash
|
|
$ 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"](../operations/configuration_files.md).
|
|
|
|
After launching server, you can use the command-line client to connect to it:
|
|
|
|
``` bash
|
|
$ 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"](../interfaces/cli.md).
|
|
|
|
Example:
|
|
``` bash
|
|
$ ./clickhouse-client
|
|
ClickHouse client version 0.0.18749.
|
|
Connecting to localhost:9000.
|
|
Connected to ClickHouse server version 0.0.18749.
|
|
```
|
|
```sql
|
|
SELECT 1
|
|
```
|
|
```text
|
|
┌─1─┐
|
|
│ 1 │
|
|
└───┘
|
|
```
|
|
|
|
**Congratulations, the system works!**
