OpenShift Node Host 설치 [1] - 작성 중

OpenShift Node 호스트 설치입니다. OpenShift Origin Comprehensive Deployment Guide를 참고하여 설치하였습니다.

OpenShift 설치 전 필요한 것들

OpenShift Origin을 설치하려면 아래 서비스를 네트워크에서 사용할 수 있어야 합니다.

DNS

MongoDB

ActiveMQ

또한 호스트(Broker, Node)에는 아래 클라이언트가 설치되어 있어야 합니다.

NTP

MCollective

1. 필수사항: 호스트 시스템 준비

이 항목은 Broker와 Node 호스트를 위해 필요한 절차입니다.

1.1.1. EPEL 저장소

최신 버전의 epel-release 패키지를 설치합니다. 최신 버전의 epel-release의 RPM 파일 경로는 http://download.fedoraproject.org/pub/epel/6/i386/repoview/epel-release.html 에서 확인할 수 있습니다.

yum install -y --nogpgcheck ${url_of_the_latest_epel-release_rpm}

설치 결과

# yum install -y --nogpgcheck http://mirror.premi.st/epel/6/i386/epel-release-6-8.noarch.rpm

Trying other mirror.

 One of the configured repositories failed (Red Hat Enterprise Linux Server 7 Optional (RPMs)),

 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. Disable the repository, 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 rhui-REGION-rhel-server-optional

     4. 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=rhui-REGION-rhel-server-optional.skip_if_unavailable=true

failure: repodata/repomd.xml from rhui-REGION-rhel-server-optional: [Errno 256] No more mirrors to try.
