This section contains hardware and software requirements for successful installation of Designer Cloud Enterprise Edition.

Platform Node Requirements

Node Installation Requirements

NOTE: If the Designer Cloud Powered by Trifacta platform is installed in a Hadoop environment, the software must be installed on an edge node of the cluster.


  • If it is integrated with a Cloudera cluster, it must be installed on a gateway node that is managed by Cloudera Manager
  •  If it is integrated with a Hortonworks cluster, it must be installed on an Ambari/Hadoop client that is managed by Hortonworks Ambari.


  • If it is integrated with an HDI cluster, it must be installed on an edge node.


  • Customers who originally installed an earlier version on a non-edge node will still be supported. If the software is not installed on an edge node, you may be required to copy over files from the cluster and to synchronize these files after upgrades. The cluster upgrade process is more complicated.


  • This requirement does not apply to the following cluster integrations:
    • AWS EMR
    • Azure Databricks

NOTE: If you are installing the Designer Cloud Powered by Trifacta platform into a Docker container, a different set of requirements apply. For more information, see Install for Docker in the Install Guide.

  • RHEL 6.4 - 6.x, 7.1, 7.2, 7.4 - 7.6



NOTE: If you are installing on CentOS/RHEL 7.1, you must be connected to an online repository for some critical updates. Offline installation is not supported for these operating system distributions.

NOTE: For security reasons, RHEL 7.3 is not supported for installation of Release 5.0 or later of the Designer Cloud Powered by Trifacta platform. Please upgrade to RHEL 7.4 or a later supported release.

NOTE: Installation on CentOS/RHEL versions 7.4 or earlier requires an upgrade of the RPM software on the Alteryx node. Details are provided during the installation process.

Tip: Disabling SELinux on the Alteryx node is recommended. However, if security policies require it, you may need to apply some changes to the environment.

  • Ubuntu 14.04 (codename Trusty) and 16.04 (codename Xenial)

    NOTE: For Ubuntu installations, some packages must be manually installed. Instructions are provided later in the process.

For more information on RPM dependencies, see System Dependencies.

Database Requirements

The following database versions are supported by the Designer Cloud Powered by Trifacta platform for storing metadata and the user's Wrangle recipes.

NOTE: One of these supported versions must be installed on the Alteryx node.

Supported versions:

  • PostgreSQL 9.6
  • MySQL 5.7 Community

    NOTE: If you are installing the databases into MySQL, you must download and install the MySQL Java driver onto the Alteryx node. For more information, see Install Databases for MySQL in the Databases Guide.


    NOTE: MySQL 5.7 is not supported for installation in Amazon RDS.

NOTE: H2 database type is used for internal testing. It is not a supported database.


For more information on installing and configuring the database, see Install Databases in the Databases Guide.

Other Software Requirements

The following software components must be present.

Java

Tip: Where possible, you should install the same version of Java on the Alteryx node and on the cluster with which you are integrating.


  • Java 1.8

    NOTE: There are additional requirements related to Java JDK listed in the Hadoop Components section listed below.

    NOTE: OpenJDK 1.8 is officially supported. It is installed on the Alteryx node during the installation process.

    NOTE: If you are integrating your Alteryx instance with S3, you must install the Oracle JRE 1.8 onto the Alteryx node. No other version of Java is supported for S3 integration. For more information, see Enable S3 Access in the Configuration Guide.

Other Software

NOTE: For Ubuntu installations, the following packages must be manually installed using Ubuntu-specific versions. Instructions and version numbers are provided later in the process.


  • NginX 1.12.2
  • NodeJS 10.13.0

Root User Access

Installation must be executed as the root user on the Alteryx node.

SSL Access

(Optional) If users are connecting to the Designer Cloud Powered by Trifacta platform, an SSL certificate must be created and deployed. See Install SSL Certificate in the Install Guide.

Internet Access

(Optional) Internet access is not required for installation or operation of the platform. However, if the server does not have Internet access, you must acquire additional software as part of the disconnected install. For more information, see Install Dependencies without Internet Access  in the Install Guide.

Hadoop Cluster Requirements

The following requirements apply if you are integrating the Designer Cloud Powered by Trifacta platform with an enterprise Hadoop cluster.

NOTE: For general guidelines on sizing the cluster, see Sizing Guidelines.

NOTE: If you have upgrades to the Hadoop cluster planned for the next year, you should review those plans with Support prior to installation. For more information, please contact Alteryx Support.

Supported Hadoop Distributions

NOTE: The Designer Cloud Powered by Trifacta platform only supports the latest major release and its minor releases of each distribution.

The Designer Cloud Powered by Trifacta platform only supports the versions of any required components included in a supported distribution. Even if they are upgraded components, use of non-default versions of required components is not supported.
