解决redhat的未注册问题

系统: RHEL 6.7 x64

桌面: Gnome

1. 查找RHN注册和订阅的程序组件。

(1) 查找subscription-manager相关组件:

执行命令: rpm -qa|grep subscription-manager

subscription-manager-gui-1.14.10-1.el6.x86_64
subscription-manager-1.14.10-1.el6.x86_64
subscription-manager-migration-1.14.10-1.el6.x86_64
subscription-manager-migration-data-2.0.22-1.el6.noarch
subscription-manager-firstboot-1.14.10-1.el6.x86_64

(2) 查找rhn相关组件:

执行命令: rpm -qa|grep rhn

rhnsd-4.9.3-2.el6.x86_64
rhn-check-1.0.0.1-32.el6.noarch
rhn-setup-gnome-1.0.0.1-32.el6.noarch
rhn-setup-1.0.0.1-32.el6.noarch
rhn-client-tools-1.0.0.1-32.el6.noarch
rhnlib-2.5.22-15.el6.noarch
yum-rhn-plugin-0.9.1-58.el6.noarch

2. 删除subscription-manager和rhn的相关程序组件。

(1) 执行命令: yum remove subscription-manager

正在删除   : subscription-manager-firstboot-1.14.10-1.el6.x86_64              1/4
正在删除   : subscription-manager-migration-1.14.10-1.el6.x86_64           2/4
正在删除   : subscription-manager-gui-1.14.10-1.el6.x86_64                      3/4
正在删除   : subscription-manager-1.14.10-1.el6.x86_64                             4/4

(2) 执行命令: yum remove rhn-check

正在删除   : rhn-setup-gnome-1.0.0.1-32.el6.noarch                        1/5
正在删除   : rhn-check-1.0.0.1-32.el6.noarch                                     2/5
正在删除   : yum-rhn-plugin-0.9.1-58.el6.noarch                               3/5
正在删除   : rhn-setup-1.0.0.1-32.el6.noarch                                      4/5
正在删除   : rhnsd-4.9.3-2.el6.x86_64                                                  5/5

这里不用rpm -e来删除程序是因为在执行删除任务的过程中会出现由于程序的相互依赖关系而无法删除的错误。

因此，用yum remove来执行删除任务，它会自动分析程序的相互依赖关系并删除。

删除完后，直接用yum源安装！！！（ 未验证！ ）      有时间试一下看起作用不，，，，这几天太忙，等周六周日再看！

-----------------------------------------------------------------------------------------------------------------------------

方法二：卸载yum ,安装CentOS的rpm包，安装yum.  刷新yum缓存，yum makecache ,具体如下，

------------------------------------------------------------------------------------------------------------------

第一步下载相关安装包

可以通过http://mirrors.163.com/centos下载，

第二步卸载Redhat自带的yum

#rpm -qa | grep yum | xargs rpm -e --nodeps

第三步安装下载的安装包

#rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

#rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

#rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

第四步到http://mirrors.163.com的 centos帮助文档
中下载CentOS6-Base-163.repo文件，存放到/etc/yum.repos.d中

#wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

第五步将Centos6-Base-163.repo中的$releasever改为Centos的版本号即可

为了防止错误，也可使用我已修改好的文件http://pan.baidu.com/s/1o6AZ23o

文件修改成如下即可：

# CentOS-Base.repo

#

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client.  You should use this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.

#

#

[base]

name=CentOS-6 - Base - 163.com

baseurl=http://mirrors.163.com/centos/6/os/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=os

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

#released updates

name=CentOS-6 - Updates - 163.com

baseurl=http://mirrors.163.com/centos/6/updates/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updates

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

#additional packages that may be useful

#additional packages that extend functionality of existing packages

[centosplus]

name=CentOS-6 - Plus - 163.com

baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplus

gpgcheck=1

enabled=0

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

#contrib - packages by Centos Users

[contrib]

name=CentOS-6 - Contrib - 163.com

baseurl=http://mirrors.163.com/centos/6/contrib/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contrib

gpgcheck=1

enabled=0

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

第六步 yum clean all 清除原有缓存

第七步 yum makecache  获取yum列表

等待，大约三分钟后出现下面提示，表示yum更改完成：

Metadata Cache Created

----------------------------------------------------------------------------------------

其实也不用这么麻烦，

1.卸载redhat自带的yum组件      rpm -qa|grep yum|xargs rpm -e --nodeps

2.安装centos的yum包, 先浏览网页看版本号，再wget 对应的版本，（因为RHEL和CentOS 的关系，包都是一样的 ），  网页：http://centos.ustc.edu.cn/centos/ 下  对应版本  下，根据机器32位还是64位 装包

http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/

# wget http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

# wget  http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
