linux - 内部服务器错误中的 GID 是什么？

Question

在服务器方面，我完全是个菜鸟。我正在尝试登录 WHM，但出现此错误:

“内部服务器错误”

500

无法为 root 获取 uid 或 gid”

我现在的问题是，什么是“gid”？我想象“uid”是“User ID”的缩写。我在谷歌上进行了广泛的搜索，但对于“gid”却一无所获。这很尴尬，我觉得对我要问的问题的回答将是“让我为你谷歌一下”......

但是无论如何，如果有人能提供任何帮助来澄清这个术语，我们将不胜感激!

Linux: Changing UIDs and GIDs for a user会注意到 UID 是“用户标识符”，GID 是“组标识符”

Wikipedia有这个位:

A group identifier, often abbreviated to GID, is a numeric value used to represent a specific group. The range of values for a GID varies amongst different systems; at the very least, a GID can be between 0 and 32,767, with one restriction: the login group for the superuser must have GID 0. This numeric value is used to refer to groups in the /etc/passwd and /etc/group files or their equivalents. Shadow password files and Network Information Service also refer to numeric GIDs. The group identifier is a necessary component of Unix file systems and processes.
