Linux | Ubuntu 14.04 LTS | Server | Nginx | Errors QnA

• Nginx 
• 아래의 모든 case 는 나의 Errors 이다.
  so, 해결방법도 나의 경우이겠지?
  
  

• 잘못된 위치에 config 파일을 생성해 놓았기 때문에 발생했다.
  "/etc/nginx/sites-enabled/" <-- 이 경로에 '/etc/nginx/sites-enabled/' 에 있는 설정파일의 soft link 를 생성해 놓았더니 발생했다.
  soft link file 을 delete 하니 사라졌다.

  2016/01/28 22:24:05 [emerg] 20607#20607: "location" directive is not allowed here in /etc/nginx/conf.d/default.conf:1

• 다음 Error 는 configuration file 에 ipV6 설정을 해 놓아서 발생함
  

  # 파일 경로 : /etc/nginx/sites-available/default

  # You should look at the following URL's in order to grasp a solid understanding
  # of Nginx configuration files in order to fully unleash the power of Nginx.

  # Generally, you will want to move this file somewhere, and start with a clean
  # file but keep this around for reference. Or just disable in sites-enabled.

  위의 설정파일에 빨간 부분을 주석을 풀고 실행시켰더니 아래와 같은 Error 가 발생함.
  사실 저걸 comment 처리하는게 해결방법은 아니고 저 ipV6 방식을 내가 실제로 사용해야할 때 저렇게 세팅을 했는데 Error 가 발생한다면
  검색해보면 해결책이 많이 나오더라.
  그 때 가서 적용해서 해결해보고 결과를 추가로 여기에 작성하자.

• 다음 Error 는 이유를 정확히 모르겠음.

  uWSGI 실행시 --http ;[port number] 설정을 해주지 않아서 난건지...
  아니면 "/etc/nginx/sites-available/[설정파일이름]" 폴더의 [설정파일] 의 내용을 잘못 작성한 건지 모르겠다.
  일단, 둘 중 하나다.
