MYSQL 5.7 INSTALL ( mysql-comunity-server-5.7.9)
O/S : Centos 6.x (64bit)
1. yum 서버를 이용하여 mysql 5.7.9 버전의 mysql을 설치해 보자
|
1 2 3 4 5 6 7 8 9 10 11 12 |
[root@localhost ~]# wget http://dev.mysql.com/get/mysql57-community-release-el6-7.noarch.rpm [root@localhost ~]# rpm -Uvh mysql57-community-release-el6-7.noarch.rpm [root@localhost ~]# yum install mysql-community-server [root@localhost ~]# rpm -qa | grep mysql mysql-community-server-5.7.9-1.el6.x86_64 mysql-community-common-5.7.9-1.el6.x86_64 mysql-community-libs-5.7.9-1.el6.x86_64 mysql-community-client-5.7.9-1.el6.x86_64 mysql57-community-release-el6-7.noarch |
2. mysqld start
|
1 2 3 |
[root@localhost ~]# /etc/rc.d/init.d/mysqld start MySQL 데이타베이스 초기화 중: [ OK ] mysqld (을)를 시작 중: [ OK ] |
3. mysql 5.7 버전에서는 시작시 패스워드가 임으로 할당되서 바로 root로 접속할수가 없다
|
1 2 |
[root@localhost ~]# mysql -u root ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) |
4. mysql데몬은 stop하고 safe 모드로 시작을 진행해서 패스워드를 변경하면 된다.

[1]+ Done /usr/bin/mysqld_safe --skip-grant-tables |
5. mysql 패스워드 정책을 LOW 로 변경 후 mysql 데몬을 올릴수 있도록
|
1 2 3 4 5 6 7 8 |
[root@localhost ~]# vi /etc/my.cnf [mysqld] validate_password_policy=LOW [root@localhost ~]# /etc/rc.d/init.d/mysqld start mysqld (을)를 시작 중: [ OK ] |
6. 위에서 패스워드 지정한 패스워드로 이제 로그인을 해보자
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
[root@localhost ~]# mysql -u root -p mysql Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement. mysql> \s ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. mysql> |
그럼 에러가 발생된다 에러는
You must reset your password using ALTER USER statement before executing this statement.
즉 root의 패스워드를 다시 한번 입력하라는 메세지이다
7. 패스워드 alter 명령어로 입력
|
1 2 3 4 5 |
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'qwer1234##$$'; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) |
8. 다시 재 로그인을 해보면 이제 패스워드 지정이 완벽하게 구성된 것을 확인 할 수 있다.
my.cnf (default-storage-engine = InnoDB)

여기서 default-storagne-engin을 myisam 을 사용할것인지 innodb를 사용할것인지 선택 후 사용하면 된다
여기 my.cnf 파일은 현재 innodb를 기본엔진으로 사용
myisam으로 변경하려면 주석 해제 후 사용 / innodb 부분은 주석처리

설치시 임의로 생성된 패스워드는 홈디렉토리인가에 .mysql_secret 으로 생성 됩니다.
