# Step 1: Install MariaDB Enterprise Server

## Overview

This page details step 1 of the 7-step procedure "[Deploy Primary/Replica Topology](/docs/server/architecture/topologies/primary-replica.md)".

This step installs MariaDB Enterprise Server

The Primary/Replica topology requires 3 or more MariaDB Enterprise Server nodes for High Availability (HA). Nodes must meet requirements.

Interactive commands are detailed. Alternatively, the described operations can be performed using automation.

## Retrieve Download Token

MariaDB Corporation provides package repositories for CentOS / RHEL (YUM) and Debian / Ubuntu (APT). A download token is required to access the MariaDB Enterprise Repository.

Customer Download Tokens are customer-specific and are available through the MariaDB Customer Portal.

To retrieve the token for your account:

1. Navigate to <https://customers.mariadb.com/downloads/token/>
2. Log in.
3. Copy the Customer Download Token.

Substitute your token for `CUSTOMER_DOWNLOAD_TOKEN` when configuring the package repositories.

## Set Up Repository

1. On each Enterprise ColumnStore node, install the prerequisites for downloading the software from the Web.\
   Install on CentOS / RHEL (YUM):

```bash
$ sudo yum install curl
```

Install on Debian / Ubuntu (APT):

```bash
$ sudo apt install curl apt-transport-https
```

2. On each Enterprise ColumnStore node, configure package repositories and specify Enterprise Server:

```bash
$ curl -LsSO https://dlm.mariadb.com/enterprise-release-helpers/mariadb_es_repo_setup
```

```bash
$ echo "${checksum}  mariadb_es_repo_setup" \
       | sha256sum -c -
```

```bash
$ chmod +x mariadb_es_repo_setup
```

```bash
$ sudo ./mariadb_es_repo_setup --token="CUSTOMER_DOWNLOAD_TOKEN" --apply \
      --skip-maxscale \
      --skip-tools \
      --mariadb-server-version="11.4"
```

*Checksums of the various releases of the `mariadb_es_repo_setup` script can be found in the* [*Versions*](/docs/server/server-management/install-and-upgrade-mariadb/mariadb-package-repository-setup-and-usage.md#versions) *section at the bottom of the* [*MariaDB Package Repository Setup and Usage*](/docs/server/server-management/install-and-upgrade-mariadb/mariadb-package-repository-setup-and-usage.md) *page. Substitute `${checksum}` in the example above with the latest checksum.*

## Install Enterprise Server

1. On each Enterprise Cluster node, install MariaDB Enterprise Server and MariaDB Enterprise Backup.

Install via CentOS / RHEL (YUM):

```bash
$ sudo yum install MariaDB-server MariaDB-backup
```

Install via Debian / Ubuntu (APT):

```bash
$ sudo apt update

$ sudo apt install mariadb-server mariadb-backup
```

Install via SLES (ZYpp):

```bash
$ sudo zypper install MariaDB-server MariaDB-backup
```
