MySQL v8.x 이상 사용자 권한 생성.

젝망치 — Sun, 27 Jun 2021 16:55:33 +0900

-- MySQL v8.x 이하 버전.
mysql> grant all privileges on DB이름.* to 계정ID@'%' identified by '계정비밀번호';
mysql> flush privileges;

-- MySQL v8.x 이상.
mysql> create user 계정ID@'%' identified by '계정비밀번호' ;
mysql> grant all privileges on DB이름.* to 계정ID@'%' with grant option;
mysql> flush privileges;

권한 주는 명령어 정책이 변경 되었나 봅니다 (비밀번호 강도도 높아 졌나 봅니다).

# application.properties
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/db?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Seoul&allowPublicKeyRetrieval=true&useSSL=false
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

기본값으로 인증 정책도 SSL 로 변경 되었나 봅니다. 개발 환경에서는 임시로 SSL 비활성화 옵션을 줘야 인증 가능.
