在使用数据库时必不可少的即是查看help帮助,通过help帮助再次寻找常用命令及参数,如下为help grant信息:
MariaDB [(none)]> help grant;
Name: 'GRANT'
Description:
Syntax:
GRANT
    priv_type [(column_list)]
      [, priv_type [(column_list)]] ...
    ON [object_type] priv_level
    TO user_specification [, user_specification] ...
    [REQUIRE {NONE | ssl_option [[AND] ssl_option] ...}]
    [WITH with_option ...]
GRANT PROXY ON user_specification
    TO user_specification [, user_specification] ...
    [WITH GRANT OPTION]
object_type:
    TABLE
  | FUNCTION
  | PROCEDURE
priv_level:
    *
  | *.*
  | db_name.*
  | db_name.tbl_name
  | tbl_name
  | db_name.routine_name
user_specification:
    user
    [
        IDENTIFIED BY [PASSWORD] 'password'
      | IDENTIFIED WITH auth_plugin [AS 'auth_string']
    ]
Normally, a database administrator first uses CREATE USER to create an
account, then GRANT to define its privileges and characteristics. For
example:
CREATE USER 'jeffrey'@'localhost' IDENTIFIED BY 'mypass';
GRANT ALL ON db1.* TO 'jeffrey'@'localhost';
GRANT SELECT ON db2.invoice TO 'jeffrey'@'localhost';
GRANT USAGE ON *.* TO 'jeffrey'@'localhost' WITH MAX_QUERIES_PER_HOUR 90;常用配置
    1.授权单位普通DBA或运维人员增删改查命令
MariaDB [(none)]> create table performance( id int, server_name varchar(20), Adress_City varchar(30) ); MariaDB [(none)]> grant select,update,delete,insert on cluster.performance to root@'172.18.0.%' identified by 'jncsy'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges;
2.授权某个用户某张表的某几列查询命令
MariaDB [(none)]> grant select(id,server_name) on cluster.performance to root@'172.18.0.%' identified by 'jncsy'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges;
    3.撤销某用户的授权权限
MariaDB [(none)]> show grants for root@'172.18.0.%'; +--------------------------------------------------------------------------------------------------------------+ | Grants for root@172.18.0.% | +--------------------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'root'@'172.18.0.%' IDENTIFIED BY PASSWORD '*429B3FB345D35EC8C8B54230AD060C07E846494A' | | GRANT SELECT, INSERT, UPDATE, DELETE ON `cluster`.`performance` TO 'root'@'172.18.0.%' | +--------------------------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec) MariaDB [(none)]> revoke select on cluster.performance from root@'172.18.0.%'; Query OK, 0 rows affected (0.00 sec)
