오늘은 복습/실습/자습 위주로 진행 되었다.
GIT
GIT은 어제 했던 내용 그대로라 무난하게 성공했다.

nginx 설치
제일 애먹었던 centos에 nginx 설치...centos8로 깔았다가 먼 길 돌아왔다. 왠만하면 centos7을 사용하자.
설치 참고
패키지 관리자를 통해 NGINX 최신 버전(Mainline/Stable) 설치하기
아무런 조치 없이 리눅스의 패키지 관리자를 통해서 웹 서버인 NGINX를 설치하게 되면 자신이 원하는 버전을 설치하지 못할뿐더러, 현재 패키지 관리자에선 구 버전이 기본 설정되어 있습니다.

느낀 점
centos 정말 낯설다...
에러메세지 때문에 구글링하고 똑같은 명령어 치는 작업을 반복하니 덕분에 도커에 조금 익숙해진 것 같다.
어쨌든 시간 내에 해내서 기쁘다!
