解决redhat的未注册问题
昨天安裝第五步的時候：開始是沒有網(wǎng)，，，居然ping不通 ?網(wǎng) ?，服務器也ping不通,,,,,可能和我前幾天刪除了網(wǎng)絡適配器有關(guān)，，把linux橋接對應的適配器給刪了，，，
解決辦法是打開虛擬網(wǎng)絡編輯器 ，以管理員身份運行 ? ?刪除vmnet0 再添加vmnet0 ,設置橋接方式，正常情況都會解決，，若還不行，，果斷卸載VM，重裝，，，避免時間浪費， ? ? ?
一切設置好后，再來不簽名的安裝glibc的調(diào)試包，，，結(jié)果報錯！！
yum --nogpgcheck --enablerepo=debug install glibc-debuginfo
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
------------------------------------------------------------
?經(jīng)過研究發(fā)現(xiàn)，其實如果使用redhat的yum源需注冊付費，費時費力，
解決辦法一（未驗證）刪除RHEL 6.7 的RHN注冊和訂閱提示
------------------------------------------------------------------------------------
系統(tǒng): RHEL 6.7 x64 桌面: Gnome? 1. 查找RHN注冊和訂閱的程序組件。?????????? (1) 查找subscription-manager相關(guān)組件:????????????????? 執(zhí)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相關(guān)組件:????????????????? 執(zhí)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-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. 刪除subscription-manager和rhn的相關(guān)程序組件。???? (1) 執(zhí)行命令:?yum remove subscription-manager? ????????????????? 正在刪除?? : subscription-manager-firstboot-1.14.10-1.el6.x86_64??????? ????? 1/4?

這里不用rpm -e來刪除程序是因為在執(zhí)行刪除任務的過程中會出現(xiàn)由于程序的相互依賴關(guān)系而無法刪除的錯誤。 因此，用yum remove來執(zhí)行刪除任務，它會自動分析程序的相互依賴關(guān)系并刪除。 刪除完后，直接用yum源安裝！！！（未驗證！） ? ? ?有時間試一下看起作用不，，，，這幾天太忙，等周六周日再看！ ----------------------------------------------------------------------------------------------------------------------------- 方法二：卸載yum ,安裝CentOS的rpm包，安裝yum. ?刷新yum緩存，yum makecache ,具體如下， ------------------------------------------------------------------------------------------------------------------
第一步下載相關(guān)安裝包
可以通過http://mirrors.163.com/centos下載，
第二步卸載Redhat自帶的yum
#rpm -qa | grep yum | xargs rpm -e --nodeps
第三步安裝下載的安裝包
#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幫助文檔?
中下載CentOS6-Base-163.repo文件，存放到/etc/yum.repos.d中
#wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
第五步將Centos6-Base-163.repo中的$releasever改為Centos的版本號即可
為了防止錯誤，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.
#
#

第六步 yum clean all 清除原有緩存
第七步 yum makecache??獲取yum列表
等待，大約三分鐘后出現(xiàn)下面提示，表示yum更改完成：
Metadata Cache Created
?----------------------------------------------------------------------------------------
其實也不用這么麻煩，
1.卸載redhat自帶的yum組件 ? ? ?rpm -qa|grep yum|xargs rpm -e --nodeps
2.安裝centos的yum包, 先瀏覽網(wǎng)頁看版本號，再wget 對應的版本，（因為RHEL和CentOS 的關(guān)系，包都是一樣的 ）， ?網(wǎng)頁：http://centos.ustc.edu.cn/centos/ 下 ?對應版本 ?下，根據(jù)機器32位還是64位 裝包 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 # wget ?http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/yum-3.2.29-73.el6.centos.noarch.rpm 3.?下載更新源，并存放在系統(tǒng)目錄中? wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo ? ??http://docs.linuxtone.org這個網(wǎng)站里邊存放了許多有用的資料，有機會可以看看 mv CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo 4. 更新yum 資源庫 yum clean all yum makecache ? 安裝完成，下來就可以裝調(diào)試包了，http://debuginfo.centos.org/6/x86_64/ --------------- linux 公社說 ?開發(fā)人員可以免費下載 Red Hat 企業(yè)版 Linux（RHEL）? ?免費領(lǐng)取RHEL7 的注冊號 ? 可以去下載一個備用轉(zhuǎn)載于:https://www.cnblogs.com/the-tops/p/5718652.html
