HENGSHI SENSE Installation FAQs

Installation Related Issues

Can the server hostname be modified after installation?

The server hostname cannot be changed after installation. If modification is required, please contact technical support for migration operations.
Specifically, for machines deploying Doris, the internal network IP cannot be changed either.

Insufficient Disk Space

[2023-05-06.11:19:13.150][hs_install:68][ ERROR ]: /opt/hengshi capacity is less than 10G, abort installation! Please check the disk or use larger disk

The issue is caused by insufficient disk space. After clearing up disk space or increasing disk capacity, proceed with the installation or upgrade process.

Can the middleware services used by HENGSHI be replaced?

The built-in modules of HENGSHI, including metadb, engine, minio, and redis, all support replacement with customers' own services to meet personalized needs:

• Replace metadb (Key point: configure HS_PG_IF_EXTERNAL=true and connection settings)
• Replace engine (Key point: configure HS_ENGINE_IF_EXTERNAL=true and connection settings)
• Replace minio (Key point: configure HS_MINIO_IF_EXTERNAL=true and connection settings)
• Replace redis (Key point: configure HS_REDIS_IF_EXTERNAL=true and connection settings)
