How can I manually change the mirror direction now?

Currently, after checking the official commands, I found that the tiup component and DM component were not packaged, and the mirror needs to be a folder rather than a compressed package.

It could also be that your tiup version is too low. Use this: tiup mirror set https://tiup-mirrors.pingcap.com

I would like to ask, this configuration should ultimately be written locally. Is there a corresponding configuration file that can be manually modified?

I understand that your goal is to create a custom image package that includes the DM component. If that’s the case, please refer to the article I wrote about the process of installing non-local image source components in an offline TiDB environment - “The Same” column - 专栏 - 记一次tidb离线环境下安装非本地镜像源组件的过程 | TiDB 社区

Thank you, I can refer to your offline image creation process. For now, I need to revert the incorrectly configured image, as the tiup component is currently unusable. :rofl:

I found it. In the .tiup root directory, there is a tiup.toml file. Deleting the mirror configuration item will solve the problem. :rofl:
