Starburst Admin - get started #
It includes the following features:
- Installation and upgrade of Starburst Enterprise platform (SEP) or Trino
using the RPM or
- Update the coordinator and worker nodes configuration files, including catalog properties files for data source configuration
- Service management of the cluster and on all nodes (start/stop/restart/status)
- Collection of logs
- Support for adding custom binary files, such as custom connectors or UDF
- Support for adding custom configuration files
All target machines must meet the requirements outlined below prior to installing Starburst Admin.
Starburst Admin does not manage the creation of the servers, the operating system installation and configuration, or the Python and Java installation. It is also not designed to manage other related tools such as Apache Ranger, a Hive Metastore Service, or any data source.
Deep knowledge of Ansible is not expected for usage, but familiarity with Ansible and Ansible playbooks is required.
The following sections detail the requirements for the machine where you run Ansible and Starburst Admin, called the control node, and the requirements for the machines where you install and manage SEP, called the cluster nodes.
Requirements for the control node #
- Ansible 2.10 or higher
- Linux/Unix operating system
- Python 2.7 and higher or Python 3.5 and higher
In addition, the following resources are needed:
- SSH connectivity to the cluster nodes
- Downloaded Starburst Enterprise platform (SEP) or Trino
tar.gzor RPM archive files on the control node, or alternatively URL to the files that is accessible on all cluster nodes
The controller node can be any machine that is configured to fulfill these requirements. For initial testing you can use your workstation or even a node in the cluster directly. Production usage should follow Ansible best practices, and use dedicated workflow or Ansible orchestration and automation tools such as Ansible Tower or Concord.
Requirements for managed cluster nodes #
Starburst Admin does not manage the cluster hardware, operating system or package installation. It relies on the existence of all the nodes in the cluster and the fact they fulfill the requirements detailed in this section.
Typically provisioning systems such as Puppet, Chef, Terraform and others are used to prepare the cluster nodes.
All cluster nodes need to fulfill the normal Starburst Enterprise platform (SEP) or Trino requirements:
- Linux operating system
- Java runtime environment
Memory and hardware resource requirements depend on the planned capacity of the cluster. Following are a few high level guidelines:
- Use identical hardware configurations for all workers.
- Start with at least two workers, scale up as needed.
- Prefer fewer, more powerful worker nodes over many smaller ones.
- For performance reasons, nodes are ideally located on the same subnet and within the same data center. All nodes communicate using TCP/IP.
Review the requirements for the specific version of SEP for additional details.
Specific testing is performed with the distributions CentOS versions 7 and CentOS 8 and Red Hat Enterprise Linux (RHEL) versions 7 and 8.
- Enabled SSH access and connectivity from the control
the configured user must have root or sudo access. If the sudo user requires a

rsync, often an optional package that needs to be installed.
bash, typically installed by default.
When using Starburst Admin with an RPM archive:
- RPM-based Linux distribution
dnf, or others are not required

Install Starburst Admin on the control node #
Starburst Admin is a collection of Ansible playbooks that you install on the control node:
- Contact Starburst Support for the Starburst Admin
- Download it onto the control node into any directory, such as
- Access the directory in a command line interface.
- Install the collection with the following command:
ansible-galaxy collection install starburst-admin-*.tar.gz
- Confirm the command finishes successfully:
Starting galaxy collection install process Process install dependency map Starting collection install process Installing 'starburst.admin:1.0.0' to '....' starburst.admin:1.0.0 was installed successfully
The collection is installed into
default. The installation path
is used for the binaries and all the configuration files for a cluster. Make
sure you manage the files in this directory with a version control system.
You can override the installation path with the option
Install on multiple control nodes #
If you need to install the collection into numerous control nodes, you can make the binary available on a remote URL:
- Make the binary available on a server via HTTP, for example,
- Create a file
requirements.ymlthat includes a link to the binary.
--- collections: # Example link to tar.gz package - https://repo.example.com/files/starburst-admin-1.0.0.tar.gz
- Use the YAML file for the installation
ansible-galaxy collection install -r requirements.yml
Next steps #
Now that you have set up the control nodes and the managed cluster nodes, you can proceed with the initial installation on the cluster.
