강사님에게 요청합니다

강사님 말씀처럼 스크립트를 구분해서 replication 부분부터 순서대로 진행했는데
replication 부분에서 바로 딱 에러가 뜨네요
--- 에러 내용---
ERROR 1794 (HY000) at line 1: Slave is not configured or failed to initialize properly. You must at least set --server-id to enable either a master or a slave. Additional error messages can be found in the MySQL error log.

계속된 질문에도 친절한 답변을 해주셔서 너무 감사드립니다

docker-compose 이후 스크립트 실행에 에러가 납니다...

요즘 바빠서 강사님 글을 놓치고 있었네요
docker compose 실행 후에 컨테이너들 정상적으로 실행중이며,&nbsp;
 강사님이 알려주신 명령을 입력하니 패스워드 보인다고 경고창 뜨는데... 어떤 결과가 나오는게 정상인건가요?

아직도 해결하지 못하고 있습니다.. 
흑흑...

강사님 답변을 받고 수정하여 컨테이너 생성 및 실행에 성공했습니다
prometheus 컨테이너 까지 실행해서&nbsp;
브라우저에서 docker_host_ip:9090/graph 를 입력해서 잘 들어가지는데

커스텀 이미지로 컨테이너 생성 시 실행이 안됩니다..

와~~~문제해결했습니다...ㅠㅠ
centos8에서 방화벽 관련 문제인거 같은데 리눅스를 잘 몰라서 정확한 이유는 모르겠지만
주석에 보니 172로 시작하는 IP는 전부 열어주라는 의미 같은데 네트워크를 두개를 써서 그런거 같습니다.
아래의 명령어를 순서대로 입력하니 되네요...

강사님 빠른 답변 감사합니다^^ 좋은 강의 잘 듣고 있고 이번 강의 다 닫고 쿠버네티스 강의도 수강 예정입니다.
계속 잘 부탁 드릴게요^^

어디에서 잘못되었는지 모르겠네요. 위의 명령어 말고도 강의에서 나온 docker-compose up 명령어를 해도 같은 에러가 나옵니다...ㅜㅜ

안녕하세요. 김영한님
JPA 강의 이후 계속 영한님 강의만 찾고있는 윌던입니다^^
현재는 JPA 좀 쉬면서 스프링 핵심원리를 듣고 있습니다.
웹 MVC 기다리다가 언제쯤 나오나 찾아보니 이런 글을 보게 되었네요.
HTTP 강의라니... 생각지도 못한 진주를 발견한 기분입니다ㅜㅜ
현재 실무에서 일하고 있어도 항상 기본기가 부족해서, 실력 향상이 느린거 같아서
고수에서 한 번쯤 배우고 싶은 주제였는데...
감사합니다.
나오면 바로 신청할게요
너무너무 기대됩니다.

다음 스프링 웹 mvc강의 출시 날짜가 궁굼합니다 ㅠㅠ

해결하셨다니 기쁘네요^^
꼭 그런지는 모르겠지만 폴더 경로하고 폴더 이름을 일치 시켜야 되더라구요...
제가 그 부분을 좀더 적었으면 FEN님 고생 덜하셨을 건데...아무튼 고생 하셨습니다

window 10 home toolbox에서 실행이 안되네요..

강사님 좋은 강의 만들어 주셔서 감사드립니다.

package.json 파일을 찾을수 없다고 자꾸 나오는데...

안녕하세요.
같은 강의를 수강하면서 리액트 핫 로딩 부분에 대해서 도움을 받아서 감사 인사 드리러 왔습니다.
안근창님 감사드립니다^^
