Hareware Environment
DolphinScheduler, as an open-source distributed workflow task scheduling system, can be well deployed and run in Intel architecture server environments and mainstream virtualization environments, and supports mainstream Linux operating system environments.
1. Linux operating system version requirements
| OS | 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 |
Attention: The above Linux operating systems can run on physical servers and mainstream virtualization environments such as VMware, KVM, and XEN.
2. Recommended server configuration
DolphinScheduler supports 64-bit hardware platforms with Intel x86-64 architecture. The following recommendation is made for server hardware configuration in a production environment:
Production Environment
| CPU | MEM | HD | NIC | Num |
|---|---|---|---|---|
| 4 core+ | 8 GB+ | SAS | GbE | 1+ |
Attention:
- The above-recommended configuration is the minimum configuration for deploying DolphinScheduler. The higher configuration is strongly recommended for production environments.
- The hard disk size configuration is recommended by more than 50GB. The system disk and data disk are separated.
3. Network requirements
DolphinScheduler provides the following network port configurations for normal operation:
| Server | Port | Desc |
|---|---|---|
| MasterServer | 5566 | Not the communication port. Require the native ports do not conflict |
| WorkerServer | 7788 | Not the communication port. Require the native ports do not conflict |
| ApiApplicationServer | 12345 | Backend communication port |
| nginx | 8888 | The port for DolphinScheduler UI |
Attention:
- 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.
4. Browser requirements
DolphinScheduler recommends Chrome and the latest browsers which using Chrome Kernel to access the front-end visual operator page.
