使用redhat 系统在线安装时提示This system is not registered with RHN.如下：

[root@localhost ~]# yum install httpd
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
Setting up Install Process
No package httpd available.
Nothing to do
解决方案：

1.卸载redhat自带的yum组件

[root@localhost ~]# rpm -qa|grep yum|xargs rpm -e --nodeps

2.安装centos的yum包

[root@localhost ~]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
[root@localhost ~]# wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
[root@localhost ~]# wget http://mirrors.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
[root@localhost ~]# rpm -ivh *.rpm
warning: yum-3.2.22-37.el5.centos.noarch.rpm: Header V3 DSA signature: NOKEY, key ID e8562897

3. 下载更新源，并存放在系统目录中
[root@localhost ~]# wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo

[root@localhost ~]#mv CentOS_Base.repo /etc/yum.repos.d/CentOS-Base.repo

4.生成缓存并进行安装

[root@localhost ~]# yum makecache
[root@localhost ~]# yum install httpd
