mysql 설치

안녕하세요. 덕분에 유익한 강의 잘 보고 있습니다.

다름이 아니라 backend ec2에서 mysql 8버전을 설치하는데 어려움을 겪고 있습니다.

가르쳐주신대로 따라해보기도 했고, 구글링해서 다른 포스팅도 따라해보았는데요.

계속 5.7버전이 설치되고 있습니다.

$ wget -c https://repo.mysql.com/mysql-apt-config_0.8.13-1_all.deb
$ sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb
-> OK
$ sudo apt-get update
$ sudo apt-get install mysql-server
-> y
-> root password 입력

실제 제가 쳤던 명령어는 위와 같고, 설치 결과는 이렇습니다.
