Install ClickHouse on rpm-based Linux distributions

Install ClickHouse on Redhat/CentOS Linux

Install ClickHouse on rpm-based distributions

It is recommended to use official pre-compiled rpm packages for CentOS, RedHat, and all other rpm-based Linux distributions.

1. Review recommendations

   Before installing ClickHouse, review the following recommendations:

   • Swap: Disable the operating system’s swap file in production environments.
   • Disk space: The ClickHouse binary requires at least 2.5 GB of disk space for installation.
   • Network: For distributed deployments (clustering), use at least 10 Gbit network connectivity. Network bandwidth is critical for processing distributed queries with large amounts of intermediate data, as well as for replication.

   Estimating storage requirements

   To estimate the disk space needed for your data:

   1. Estimate data volume: Take a sample of your data and calculate the average row size, then multiply by the number of rows you plan to store.
   2. Apply the compression coefficient: Load a sample into ClickHouse and compare the original data size with the stored table size. Clickstream data, for example, is typically compressed 6-10x.
   3. Account for replicas: If you plan to store data in multiple replicas, multiply the estimated volume by the number of replicas.

   For more detailed hardware requirements, see “Sizing and hardware recommendations”

2. Set up the RPM repository

   Add the official repository by running the following command:

   sudo yum install -y yum-utils
   sudo yum-config-manager --add-repo https://packages.clickhouse.com/rpm/clickhouse.repo
   

   For systems with zypper package manager (openSUSE, SLES), run:

   sudo zypper addrepo -r https://packages.clickhouse.com/rpm/clickhouse.repo -g
   sudo zypper --gpg-auto-import-keys refresh clickhouse-stable
   

   In the steps below, yum install can be replaced by zypper install, depending on which package manager you’re using.

3. Install ClickHouse server and client

   To install ClickHouse run the following commands:

   sudo yum install -y clickhouse-server clickhouse-client
   

   • You can replace stable with lts to use different release kinds based on your needs.
   • You can download and install packages manually from packages.clickhouse.com/rpm.
   • To specify a particular version, add -$version to the end of the package name, for example:

   sudo yum install clickhouse-server-22.8.7.34
   
4. Start ClickHouse server

   To start ClickHouse server, run:

   sudo systemctl enable clickhouse-server
   sudo systemctl start clickhouse-server
   sudo systemctl status clickhouse-server
   

   To start ClickHouse client, run:

   clickhouse-client
   

   If you set up a password for your server, then you will need to run:

   clickhouse-client --password
   
5. Install standalone ClickHouse Keeper

   In production environments we strongly recommend running ClickHouse Keeper on dedicated nodes. In test environments, if you decide to run ClickHouse Server and ClickHouse Keeper on the same server, then you don’t need to install ClickHouse Keeper as it is included with ClickHouse server.

   To install clickhouse-keeper on standalone ClickHouse Keeper servers, run:

   sudo yum install -y clickhouse-keeper
   
6. Enable and start ClickHouse Keeper

   sudo systemctl enable clickhouse-keeper
   sudo systemctl start clickhouse-keeper
   sudo systemctl status clickhouse-keeper
