Hardware Environment

This section briefs about the hardware requirements for DolphinScheduler. DolphinScheduler works as an open-source distributed workflow task scheduling system. It can deploy and run smoothly in Intel architecture server environments and mainstream virtualization environments. It also supports mainstream Linux operating system environments and ARM architecture.

Linux Operating System Version Requirements

The Linux operating systems specified below can run on physical servers and mainstream virtualization environments such as VMware, KVM, and XEN.

Operating System Version
Red Hat Enterprise Linux 7.0 and above
CentOS 7.0 and above
Oracle Enterprise Linux 7.0 and above
Ubuntu LTS 16.04 and above

Note: The above Linux operating systems can run on physical servers and mainstream virtualization environments such as VMware, KVM, and XEN.

Server Configuration

DolphinScheduler supports 64-bit hardware platforms with Intel x86-64 architecture. The following table shows the recommended server requirements in a production environment:

Production Environment

CPU MEM HD NIC Num
4 core+ 8 GB+ SAS GbE 1+

Note:

  • The above recommended configuration is the minimum configuration for deploying DolphinScheduler. Higher configuration is strongly recommended for production environments.
  • The recommended hard disk size is more than 50GB and separate the system disk and data disk.

Network Requirements

DolphinScheduler provides the following network port configurations for normal operation:

Server Port Desc
MasterServer 5678 not the communication port, require the native ports do not conflict
WorkerServer 1234 not the communication port, require the native ports do not conflict
ApiApplicationServer 12345 backend communication port

Note:

  • MasterServer and WorkerServer do not need to enable communication between the networks. As long as the local ports do not conflict.
  • Administrators can adjust relevant ports on the network side and host-side according to the deployment plan of DolphinScheduler components in the actual environment.

Browser Requirements

The minimum supported version of Google Chrome is version 85, but version 90 or above is recommended.
