ClickHouse is a popular open-source column-oriented database management system. It is known for its high performance and is particularly well-suited for real-time analytics. In this guide, we will walk you through the process of installing ClickHouse on an Ubuntu 22.04 server.
Before we begin, make sure you have the following:
- An Ubuntu 22.04 server with sudo privileges.
- Access to the terminal or command-line interface.
Step 1: Update System Packages
First, it’s a good practice to ensure that your server’s package database is up to date. Open a terminal and run the following command:
sudo apt update && sudo apt upgrade -y
This command will update the package lists and upgrade any outdated packages to their latest versions.
Step 2: Install ClickHouse
You can install ClickHouse on Ubuntu 22.04 using the official APT repository. Here are the commands to add the repository and install ClickHouse:
sudo apt install apt-transport-https -y sudo sh -c 'echo "deb https://packagecloud.io/altinity/clickhouse/ubuntu/ bionic main" > /etc/apt/sources.list.d/clickhouse.list' sudo apt-key adv --keyserver keyserver.ubuntu.com --recv E0C56BD4 sudo apt update sudo apt install clickhouse-server clickhouse-client -y
The above commands do the following:
- Install the
apt-transport-httpspackage, which allows APT to use HTTPS repositories.
- Add the ClickHouse APT repository to your server’s sources list.
- Import the repository’s GPG key for verification.
- Update the package list.
- Install the ClickHouse server and client packages.
Step 3: Start and Enable ClickHouse
Once ClickHouse is installed, you can start the service and enable it to start automatically on boot using the following commands:
sudo systemctl start clickhouse-server sudo systemctl enable clickhouse-server
To verify that ClickHouse is running, you can use:
sudo systemctl status clickhouse-server
Step 4: Access ClickHouse
By default, ClickHouse listens on port 9000 for client connections. You can access ClickHouse using the
clickhouse-client command-line tool. For example, to connect to ClickHouse, use the following command:
You can now run SQL queries and interact with ClickHouse through the command-line interface.
