如何解决 yum安装出现This system is not registered with RHN
[root@localhost ~]# yum install libtool
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
Setting up Install Process
Nothing to do
A、在线yum 要连接网络
解决方案：
1、进入/etc/yum.repos.d/目录。
在命令行输入：wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
2、ls 一下，会看到一个文件名为CentOS-Base.repo的文件。
3、将原来的文件rhel-debuginfo.repo改名为rhel-debuginfo.repo.bak
4、将CentOS-Base.repo改名为rhel-debuginfo.repo这时
这时再运行yum install libtool
B、本地安装创建本地yum
1.创建两个目录
mkdir /media/cdrom 作为挂载光盘使用
mkdir /var/yum 作为我们的yum源
2.挂载光盘
将光盘挂载到 /media/cdrom
mount /dev/cdrom /media/cdrom
3.将光盘的内容复制到/var/yum目录中
cp -r /media/cdrom /var/yum
这个过程时间较长，请耐心等待
4.检查当前是否安装createrepo包的安装情况
#rpm -q createrepo
如果显示尚未安装，则需要执行如下的命令完成安装：
cd /var/yum/Server/
rpm -ivh /var/yum/Server/createrepo-0.4.4-2.fc6.n0arch.rpm
创建yum repository的xml-rpm-metadata.执行如下命令：
#createrepo -g /var/yum/Server/repodata/comps-rhel5-server-core.xml /var/yum/Server
#createrepo -g /var/yum/VT/repodata/comps-rhel5-server-core.xml /var/yum/VT/
#createrepo -g /var/yum/Cluster/repodata/comps-rhel5-cluster.xml /var/yum/Cluster
#createrepo -g /var/yum/ClusterStorage/repodata/comps-rhel5-cluster-st.xml /var/yum/ClusterStorage/
****以上第4步骤可以不使用 因为redha6版本光驱里边已经创建了yum数据序列文件直接使用即可
****这里使用的光驱是redhat6直接配置客户端repo文件即可。
5.创建本地yum客户端repo文件，以使用本地yum repository:
#cd /etc/yum.repo.d/
#vim local.repo
注：local.repo可以随便命名，但必须以.repo为后缀。这个文件定义了yum源的位置。装软件包的时候，就到这个文件中定义的位置去找。
如果没有这样的文件，可以自己手动去创建一个。假设我们就起名叫local.repo
在这个文件中添加如下内容
[Server]
name=Server
baseurl=file:///media/Server
gpgcheck=0
enabled=1
[ScalableFileSystem]
name=ScalableFileSystem
baseurl=file:///media/ScalableFileSystem
gpgcheck=0
enabled=1
[ResilientStorage]
name=ResilientStorage
baseurl=file:///media/ResilientStorage
gpgcheck=0
enabled=1
[LoadBalancer]
name=LoadBalancer
baseurl=file:///media/LoadBalancer
gpgcheck=0
enabled=1
[HighAvailability]
name=HighAvailability
baseurl=file:///media/HighAvailability
gpgcheck=0
enabled=1
然后保存退出就可以了，接下来，就要验证本地yum repository有没有创建成功了。
用yum装一个软件试试看
#yum install httpd
如果能正常安装，那么恭喜你，本地yum repository创建成功。
