 One of the configured repositories failed (MongoDB Repository),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=mongodb-org-ex-4.2 ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable mongodb-org-ex-4.2
        or
            subscription-manager repos --disable=mongodb-org-ex-4.2

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=mongodb-org-ex-4.2.skip_if_unavailable=true

뭐가 문제인지 모르겠어서 일단 네트워크 전송은 잘 되는지 확인

ping 8.8.8.8
nmcli d

em2는 찾아도 안나와서 다시 제대로 찾아봐야 할 듯.

그래도 핵심 두개 다 연결되어있고 전송보내기 받기 모두 잘 된다.

 

구글링을 해보니 레포지토리 제거하고 yum을 클린하거나  exclude 하라는 등 뭐 많이 있어서 다 해봤다.

// clean all
sudo rm -rf /etc/yum.repos.d/mongod*
rm -fr /var/cache/yum/*
sudo yum clean all

// create again
sudo vi /etc/yum.repos.d/mongodb-org-4.2.repo
# 아직 에러

// 구글링해보고 마지막 이거밖에 안남은 상황
dhclient
# 해결!!!!!!!!!!!!!!!!

설치는 완료, 근데 data/db가 없다고 한다. 만들었는데?

연결이 안 된 것

나는 원격으로 진행중이었고 데이터도 ec2 내부에 둘거라 C:\관련된 내용은 의미없었다.

// 심볼릭링크 연결
// mongod.conf에서 지정한 데이터경로는 -f 흐름 이후 진행
mongod -f /etc/mongod.conf

상기 코드 실행시 디비 경로 연결은 완료

 

아직 에러 다 못잡았는데 이건 내일 하기로하자.
