[Edit this page](https://github.com/ClickHouse/clickhouse-docs/blob/main/docs/getting-started/install/redhat.md)

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

Review recommendations

## Review recommendations[​](#review-recommendations "Direct link to 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.

Set up the RPM repository

## Set up the RPM repository[​](#setup-the-rpm-repository "Direct link to 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.

Install ClickHouse server and client

## Install ClickHouse server and client[​](#install-clickhouse-server-and-client-1 "Direct link to 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](/docs/knowledgebase/production) based on your needs.
- You can download and install packages manually from [packages.clickhouse.com/rpm](https://packages.clickhouse.com/rpm/stable).
- 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
```

Start ClickHouse server

## Start ClickHouse server[​](#start-clickhouse-server-1 "Direct link to 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
```

Install standalone ClickHouse Keeper

## Install standalone ClickHouse Keeper[​](#install-standalone-clickhouse-keeper-1 "Direct link to Install standalone ClickHouse Keeper")

Tip

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
```

Enable and start ClickHouse Keeper

## Enable and start ClickHouse Keeper[​](#enable-and-start-clickhouse-keeper-1 "Direct link to Enable and start ClickHouse Keeper")

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