Mysql 암호 초기화


- Mysql 암호 분실시 재설정

 

1. /etc/init.d/mysql stop
2. ps -ef |grep mysql
3. mysqld_safe --skip-grant-tables &
4  mysql -u root -p
   Enter password:   (여기서 그냥 엔터 쳐야함. 초기화되었기 때문에)
5. mysql> use mysql
6. mysql> update user set password=PASSWORD("암호") where user='root';
7. mysql> flush privileges;
8. mysql> exit
9. /etc/init.d/mysql start

Mysql 에서도 Oracle 의 pfile , spfile 과 유사한 option 화일이 존재한다.


그게 흔히 볼수 있는 /etc/my.cnf 화일이다. 여기다 셋팅하고 Mysql 내렸다 올리면 적용되는 것인데..


각각의 값들은 System variables 이라고 해서 해당 값들을 개별적으로 설정할 수 있다.

역시 마찬가지로 Oracle 과 유사하게 Static, Dynamic 개념이 존재하며 Mysql 에서는 Global, session level 로 구분이 된다. 해당 release version 마다 default 값들이 다를수 있으므로 버전별로 정확한 값들은 reference manual 을 참조해야 한다.


- 조회방법


Mysql 에서 해당 변수이름을 정확히 알고 있다면..


mysql> SHOW VARIABLES LIKE 'max_join_size';

mysql> SHOW SESSION VARIABLES LIKE 'max_join_size';


해당 변수이름을 대충 알고 있다면..


mysql> SHOW VARIABLES LIKE '%size%';

mysql> SHOW GLOBAL VARIABLES LIKE '%size%';


Dynamic 변수는 아래와 같은 예로 바로 적용 가능.


set autoaucommit=0
