devheedoo / MySQL 설치 시 ERROR 2002.md

MacOS에서 MySQL 설치 도중 다음과 같은 오류가 발생했다:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock (2)'

아래 명령어까지는 정상적으로 실행됐다:

brew install mysql

devheedoo / MySQL8 비밀번호 암호화 방식 호환성 문제.md
Last active July 17, 2022 03:08

발생 원인

MySQL 을 사용하는 경우,

ERROR: Client does not support authentication protocol requested by server; consider upgrading MySQL client

위와 같은 오류를 만났다면 이는 암호화 방식의 차이 때문이다.
