[Linux][CentOS 5.7] yum 사용할 시 'YumRepo Error: All mirror URLs are not using ftp, http[s] or file.' 에러 해결방법

환경
OS: CentOS 5.7 64bit



증상

git을 설치하기 위해 yum 실행하면 아래와 같이 에러가 발생한다.
1004lucifer

[root@localhost ~]# yum install git
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
 Eg. Invalid release/
removing mirrorlist with no valid mirrors: /var/cache/yum/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base
[root@localhost ~]# 

해결방법

yum을 통해 받을 미러리스트가 없어서 정상적으로 수행되지 못했다.
미러리스트를 만들어주면 된다.
(5.7 과 같은 버전은 본인의 CentOS 버전에 맞게 수정해 주면 된다.)

[root@localhost ~]# echo "http://vault.centos.org/5.7/os/x86_64/" > /var/cache/yum/base/mirrorlist.txt
[root@localhost ~]# echo "http://vault.centos.org/5.7/extras/x86_64/" > /var/cache/yum/extras/mirrorlist.txt
[root@localhost ~]# echo "http://vault.centos.org/5.7/updates/x86_64/" > /var/cache/yum/updates/mirrorlist.txt

나같은경우 처음에 디렉토리가 없어서 그런지 명령어 수행 시 디렉토리가 없다고 나오다가 'yum install git' 한번씩 수행하면 디렉토리가 만들어 지는지..
그 다음에서야 명령어가 정상적으로 수행이 되었다.

사용되는 소스는 아래와 같다.
(클래스명 같은건 좀 변경을 했다.)

ClassName obj = objectMapper.readValue(new URL(URL + "?param"), ResponseObject.class);

원인분석 방법
1004lucifer
내 PC의 브라우저로 해당 URL 로 접속 시 예상했던대로 JSON 응답이 왔다.
하지만 실제 프로그램이 실행되는 서버에서 해당 URL 접속 시 예상했던 JSON 응답이 아닌 HTML 형식으로 응답을 받는 것을 확인할 수 있었다.




'프로그램이 수행되는 곳' 에서 요청을 날릴 시 JSON 이 아니라 HTML 로 응답이 오기 때문에 문제가 발생한 것.

[JHipster] mvnw 실행 시 'Some Enforcer rules have failed. Look above for specific messages explaining why the rule failed' 오류

증상

JHipster 가 어떤건지 한번 볼까 싶어 받아서 예제에 있는대로 하나하나 따라하는데 아래와 같이 나오며 구동을 못시키는 상황이 되었다.

JDK1.8 설치 및 JAVA_HOME 환경변수까지 잡아준 후 다시 구동(>mvnw) 을 하니 정상적으로 수행이 되었다.
