MySQL查看用戶權限的兩種方法

http://yanue.net/post-96.html

MySQL查看用戶權限命令的兩方法:

一. 使用MySQL grants

MySQL grant詳細用法見:http://yanue.net/post-97.html使用方法:

  
  
  
  

   
   
   
   
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. 直接經過mysql select查詢語句:

  
  
  
  

   
   
   
   
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)
  
  
  
  

能夠看到Select_priv,Insert_priv,Update_priv...等爲N表示沒有權限,該用戶權限一目瞭然.這時能夠使用命令

給用戶加權限:

見http://www.yanue.net/post-97.html

  
  
  
  

   
   
   
   
grant all privileges on *.* to 'test'@'127.0.0.1' identified by 'passwd';

   
   
   
   
flush privileges;
  
  
  
  

另外:show能夠看到不少東西:

  
  
  
  

   
   
   
   
show databases;

   
   
   
   
show tables;

   
   
   
   
show create database dbname;  // 這個能夠看到建立數據庫時用到的一些參數。

   
   
   
   
show create table tablename;   // 能夠看到建立表時用到的一些參數
