MySQL查看用戶權限的兩種方法

本文章來給各位同學詳細介紹關於MySQL查看用戶權限的兩種方法 ，各位同學不防進入參考。

ySQL查看用戶權限命令的兩方法:

一. 使用MySQL grants

使用方法:

 代碼如下 復制代碼

mysql> show grants for username@localhost;實例:

mysql> show grants for root@localhost;
+---------------------------------------------------------------------+
| Grants for root@localhost                                           |
+---------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION |
+---------------------------------------------------------------------+
1 row in set (0.01 sec)

 二. 直接通過mysql select查詢語句:

 代碼如下 復制代碼 mysql> select * from mysql.user where user='test' and host='127.0.0.1' G;
*************************** 1. row ***************************
                  Host: 127.0.0.1
                  User: test
              Password: *EB3C643405D7F53BD4BF7FBA98DCF5641E228833
           Select_priv: N
           Insert_priv: N
           Update_priv: N
           Delete_priv: N
           Create_priv: N
             Drop_priv: N
           Reload_priv: N
         Shutdown_priv: N
          Process_priv: N
             File_priv: N
            Grant_priv: N
       References_priv: N
            Index_priv: N
            Alter_priv: N
          Show_db_priv: N
            Super_priv: N
 Create_tmp_table_priv: N
      Lock_tables_priv: N
          Execute_priv: N
       Repl_slave_priv: N
      Repl_client_priv: N
      Create_view_priv: N
        Show_view_priv: N
   Create_routine_priv: N
    Alter_routine_priv: N
      Create_user_priv: N
            Event_priv: N
          Trigger_priv: N
Create_tablespace_priv: N
              ssl_type:
            ssl_cipher:
           x509_issuer:
          x509_subject:
         max_questions: 0
           max_updates: 0
       max_connections: 0
  max_user_connections: 0
                plugin: mysql_native_password
 authentication_string:
      password_expired: N
1 row in set (0.00 sec)

可以看到Select_priv,Insert_priv,Update_priv…等為N表示沒有權限,該用戶權限一目了然.

這時可以使用命令給用戶加權限

 

 代碼如下 復制代碼

grant all privileges on *.* to 'test'@'127.0.0.1' identified by 'passwd';
flush privileges;另外:show可以看到很多東西:

show databases;
show tables;
show create database dbname;  // 這個可以看到創建數據庫時用到的一些參數。
show create table tablename;   // 可以看到創建表時用到的一些參數
