Why install ClickHouse client?

clickhouse-client lets you run SQL against a ClickHouse server directly from your terminal, automate reports, and copy data between systems faster than GUI tools.

What are the system requirements?

You need an x64 machine, network access to the ClickHouse server’s TCP (9000) or HTTP (8123) port, and root or Administrator privileges for installation.

How do I install clickhouse-client on Linux?

APT-based distributions (Ubuntu/Debian)

sudo apt-get install -y clickhouse-client installs the latest client from your distro repo.For official builds add Yandex repo first.

YUM-based distributions (CentOS/RHEL/Amazon Linux)

sudo yum install -y clickhouse-client or with DNF on Fedora. Ensure /etc/yum.repos.d/ClickHouse.repo points to the right major version.

How do I install clickhouse-client on macOS?

Use Homebrew: brew install clickhouse.Brew taps the official Altinity formula and pulls both server and client; only the client binary is needed to connect.

How do I install clickhouse-client on Windows?

Download the pre-built ZIP from the ClickHouse releases page, unzip, and add the folder containing clickhouse-client.exe to your PATH. Or use choco install clickhouse-client.

How do I test the installation?

Run clickhouse-client --version. You should see the semantic version string.Then connect: clickhouse-client -h localhost --query "SELECT 1".

How do I connect to an "ecommerce" database?

clickhouse-client --host db.example.com --user analyst --password secret --database ecommerce drops you into an interactive prompt where you can query tables like Customers, Orders, and OrderItems.

What are best practices after installation?

Create a ~/.clickhouse-client/config.xml with default host, port, and user to avoid typing them. Use --query for scripts and CI, and pipe output to CSV for downstream tools.

Common Mistakes

Using mismatched client/server versions – features like new aggregate functions may fail. Always install a client equal to or newer than the server.
Forgetting to open TCP port 9000 in a firewall – the client hangs until it times out. Allow inbound traffic or use the HTTP port 8123 with --port.
