1. 계정설정에 필요한 테이블은 2개

  mysql> select * from mysql.user ; <= 유저가 가지고 있는 시스템 권한 부여  
  mysql> select * from mysql.db ;   <= 디비에별 유저에 대한 권한설정

2. 계정 생성 방법

 1)디비 생성
  create database mare_db;

 

 2)해당 디비에 대한 권한 부여 
   방법1) mysql> insert into db values('localhost','mare_db','mare','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');
   방법2) mysql>grant all on mare_db.* to mare@localhost;

   localhost => localhost 만 접속 가능함

   %          => any IP 접속 가능

   192.168.4.15 => 192.168.4.15 IP 만 접속 가능 (보안 설정시 특정 아이피 기입)

 

 3) 해당 계정에 대한 시스템 권한 부여
   방법1) mysql> insert into user values('localhost','mare',password 

                      ('12345'),'N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N','N',1,'','','','','',''); 

                      (일반유저 생성시에는 시스템에 권한부여 하지않음)
   방법2) mysql> create user test identified by '1234' ; ( 권한 부여 하지 않고 일반 유저 생성)
            mysql> flush privileges ;
