System Requirements
This section contains hardware and software requirements for successful installation of Designer Cloud Powered by Trifacta Enterprise Edition.
Platform Node Requirements
Node Installation Requirements
IftheDesigner Cloud Powered by Trifacta platformis 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 Cloudera Data Platform, it must be installed on an edge node of the cluster.
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.

Note
The latest stable release of PostgreSQL 12 is installed with the Designer Cloud Powered by Trifacta platform. If you need to install an earlier version of PostgreSQL 12, you can perform those installations manually.
PostgreSQL 11.X
Note
PostgreSQL 11 is supported for Azure installs only. Installation on Azure requires PostgreSQL 11. Please follow the database installation instructions for PostgreSQL 12, modifying them for version 11.
MySQL 5.7 Community
Note
MySQL 5.7 Community is not supported on CentOS/RHEL 8.x.
Notes on database versions:
MySQL 5.7 is not supported for installation in Amazon RDS.
Note
If you are installing or upgrading a deployment of Designer Cloud Powered by Trifacta Enterprise Edition that uses or will use a remote database service, such as Amazon RDS, for hosting the Alteryx databases, please contact Alteryx Customer Success and Services. For this release, additional configuration may be required.
If you are installing the databases into MySQL, you must download and install the MySQL Java driver onto theTrifacta node. For more information, seeInstall Databases for MySQLin the Databases Guide.
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
Where possible, you should install the same version of Java on theTrifacta nodeand on the cluster with which you are integrating.
Java 11 (runtime) (recommended)
Java 8
Notes on Java versions:
OpenJDK 8 and 11 are supported.
Note
If you are using Azure Databricks as a datasource, please verify that openJDKv1.8.0_302 or earlier is installed on the Trifacta node. Java 8 is required. There is a known issue with TLS v1.3.
There are additional requirements related to Java JDK listed in the Hadoop Components section listed below.
If you are integrating yourAlteryx instance with S3, you must install the Oracle JRE 1.8 onto theTrifacta node. No other version of Java is supported for S3 integration. For more information, seeS3 Accessin the Configuration Guide.
Other Software
For Ubuntu installations, the following packages must be manually installed using Ubuntu-specific versions:
Nginx: 1.22.1

Instructions and version numbers are provided later in the process.
Root User Access
Installation must be executed as the root user on the Trifacta 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.
