Redhat Enterprise Linux 는 상용 리눅스로 유지보수에 대한 Subscription을 구매후 Redhat RHN을 통해 Subscription 활성화 후 아래와 같이 OS상에서 rhn_register 과정을 통해 yum 유지보수 서비스를 받을 수 있다.
|
[root@REL-Server01 ~]#
[root@REL-Server01 ~]#
[root@REL-Server01 ~]# rhn_register
[root@REL-Server01 ~]#
[root@REL-Server01 ~]# |
하지만 RHN ID와 Subscription 에 이상이 없음에도 아래와 같은 에러와 함께 yum service를 제공 받을 수 없을 때가 있다.
|
[root@REL-Server01 ~]#
[root@REL-Server01 ~]# cat /etc/sysconfig/rhn/up2date | grep serverURL

Redhat 에 SR을 통해 답변 받은 결과로는 yum 사용전 rhn 인증 과정을 거치게 되며 이때 사용되는 패키지가 손상되었거나 구버전일 경우 Redhat Yum Repository 의 인증 정보와 일치하지 않아 생기는 에러일 수 있다는 답변을 받았다.
이에 다음과 같은 조치로 Yum Repository 를 복구가 가능하다.
1. 해당 OS의 버전을 확인
|
[root@REL-Server01 /]#
[root@REL-Server01 /]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.8 (Tikanga)
[root@REL-Server01 /]#
[root@REL-Server01 /]# uname -a
Linux REL-Server01 2.6.18-308.el5xen #1 SMP Fri Jan 27 17:26:57 EST 2012 x86_64 x86_64 x86_64 GNU/Linux
[root@REL-Server01 /]#
[root@REL-Server01 /]# getconf LONG_BIT
64
[root@REL-Server01 /]#
[root@REL-Server01 /]# |
2. 해당 OS의 최신 ISO를 준비
|
rhel-server-5.9-x86_64-dvd.iso |
3. 아래와 같이 추가된 해당 OS ISO를 마운트
(XenServer 이하 VM 환경이기 때문에 Xen ISO Attach 를 통하여 CD-ROM 형식으로 마운트)
|
[root@REL-Server01 /]#
[root@REL-Server01 /]# df -h

4. mount 된 ISO 파일내 mediaid 정보 확인 및 yum local repository 생성을 위한 repo config 작성
|
[root@REL-Server01 /]#
[root@REL-Server01 /]# head -1 /mnt/.discinfo
1354216429.587870
[root@REL-Server01 /]#

name=RHEL 5 Server DVD
baseurl=file:///mnt/Server
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1
gpgcheck=1 |
5. Local Repository 이용을 위한 Redhat Repository 정보 및 인증 정보 disable 처리
|
[root@REL-Server01 /]# vi /etc/yum/pluginconf.d/rhnplugin.conf
[root@REL-Server01 /]#
[main]
enabled = 1 # 0으로 변경
gpgcheck = 1

enabled = 1 # 0으로 변경
[root@REL-Server01 /]#
[root@REL-Server01 /]# vi /etc/yum/pluginconf.d/security.conf
[root@REL-Server01 /]#
[main]
enabled=1 # 0으로 변경
[root@REL-Server01 /]#
[root@REL-Server01 /]#
|
6. Yum Repository 캐시정보 삭제 및 Local Repository 패키지를 통한 rhn-tools-client 등 관련 패키지 업데이트
|
[root@REL-Server01 /]#
[root@REL-Server01 /]# yum clean all
