用戶怎麽管理？

-- 創建用戶

- create user [email protected] ip地址’ indentified by ‘密碼’;

-- 刪除用戶

- drop user [email protected] ip地址’;

-- 修改用戶

-rename user [email protected] ip地址’ to [email protected] ip地址’;

-- 修改密碼

- set password for [email protected] ip地址’ = password(‘新密碼’)

但是用戶創建了，沒有授權是沒法登錄

-- show grants for [email protected] ip地址’

-- 查看權限

-- grant 權限 on 數據庫.表 to [email protected] ip地址’

-- 給某個用戶在某個數據庫或者數據庫中某個表進行授權

-- remove 權限 on 數據庫.表 from [email protected]
