MySQL查询用户权限
介绍两种查看MySQL用户权限的两种方法
1、 使用MySQL grants命令
mysql> show grants for username@localhost; +---------------------------------------------------------------------+ | Grants for root@localhost | +---------------------------------------------------------------------+ | GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION | +---------------------------------------------------------------------+
需要注意的是:
- username和ip的组合需要是在mysql.user表中存在的,具体可以通过
select * from mysql.user
命令查看 - ip地址如果是通配符格式需要加引号,例如:
show grants for root@'172.%'
;
2、 使用MySQL select命令
mysql> select * from mysql.user where user='root' and host='localhost' \G; *************************** 1. row *************************** Host: localhost User: root Password: ********************** Select_priv: Y Insert_priv: Y Update_priv: Y Delete_priv: Y Create_priv: Y Drop_priv: Y Reload_priv: Y Shutdown_priv: Y Process_priv: Y File_priv: Y Grant_priv: Y References_priv: Y Index_priv: Y Alter_priv: Y Show_db_priv: Y Super_priv: Y Create_tmp_table_priv: Y Lock_tables_priv: Y Execute_priv: Y Repl_slave_priv: Y Repl_client_priv: Y Create_view_priv: Y Show_view_priv: Y Create_routine_priv: Y Alter_routine_priv: Y Create_user_priv: Y Event_priv: Y Trigger_priv: Y Create_tablespace_priv: Y 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 (0.01 sec)
