PhpMyAdmin的'特权”选项卡与'用户帐户”选项卡有何不同？

"User accounts"管理用户身份，"Privileges"管理用户权限。具体来说：1. User accounts用于创建、删除用户，查看用户名、主机、密码状态，并修改登录凭证或连接限制；2. Privileges用于分配或撤销数据库、表级别的操作权限，如SELECT、INSERT、UPDATE、DELETE，以及全局权限如重载MySQL服务器或授予其他用户权限。两者分工明确，常配合使用，例如先在User accounts创建用户，再通过Privileges设定权限。

If you've ever looked at phpMyAdmin's user management sections, you might have noticed two tabs that seem related but aren't exactly the same: "Privileges" and "User accounts". Let’s cut straight to it — they both deal with user management, but each serves a slightly different purpose.

What the "User accounts" tab is for

The User accounts tab gives you an overview of all MySQL users on the server. It shows things like:

• Username
• Host (which host the user can connect from)
• Password status (whether one is set or not)

This is where you create new users or delete existing ones. Think of it as your main directory of who exists in the system. You can also edit basic account properties here — things like renaming a user or changing their authentication method.

Some key actions you might do here:

• Add a new user account
• Delete an outdated account
• Change which hosts a user can log in from
• Set or change a password

It doesn’t go too deep into what those users can actually do — that’s where the Privileges tab comes in.

What the "Privileges" tab does differently

The Privileges tab focuses more on permissions — in other words, what each user is allowed to do. Here, you can assign or remove specific database and table-level privileges.

You’ll see things like:

• Which databases or tables a user has access to
• Whether they can SELECT, INSERT, UPDATE, DELETE
• If they’re allowed to create or drop tables/databases

It’s the place to fine-tune access control. For example, if you want to give a user full access to one database but only read access to another, this is where you’d set that up.

Also, some global privileges — like the ability to reload the MySQL server or grant other users privileges — are shown here too.

When to use which tab

To make it practical, here’s how to decide which tab to go to depending on what you're trying to do:

Use User accounts when:

• You need to add or remove a user
• You want to check which users exist
• You need to update login credentials or connection restrictions

Use Privileges when:

• You want to adjust what a user can do (e.g., read-only vs full access)
• You're troubleshooting permission errors
• You need to grant or revoke specific privileges across databases or tables

They often work together — for example, you might create a user in User accounts, then switch to Privileges to give them access to certain databases.

So yeah, the difference boils down to:
User accounts = who exists
Privileges = what they can do

They’re separate but complementary tools for managing MySQL users in phpMyAdmin.基本上就这些。
