一般安装好redhat后，不能注册的话，不能使用系统自带的yum源。但是我们可以自己配置yum源来解决这一问题。下面介绍下redhat配置163yum源。
1. 检查是否安装yum包
rpm -qa |grep yum
2. 删除自带的yum包
rpm -qa|grep yum|xargs rpm -e --nodeps
因为一些包之间可能会有依赖关系，所以我们需要加上参数 --nodeps 无视依赖关系。
3. yum包
Yum包地址http://mirrors.163.com/centos/
在这个网站里，你可以自己选择需要的文件，进入形如5/或者6/的文件，其他的无法。 (rpm 版本会更新)
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-73.el6.centos.noarch.rpmwget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpmwget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
4. 解压yum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-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
5. 替换yum源
cd /etc/yum.repos.d/wget http://mirrors.163.com/.help/CentOS6-Base-163.repovi CentOS6-Base-163.repo
注意原来的yum源配置文件是rhel-source.repo。这里把CentOS6-Base-163.repo替换掉rhel-source.repo。
mv rhel-source.repo rhel-source.repo.bakmv CentOS6-Base-163.repo rhel-source.repo
6. 编辑替换后的rhel-source.repo。
#rhel-source.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.
