2：生成的源文件
[root@localhost ~]# ls
anaconda-ks.cfg       Desktop      install.log.syslog
CentOS-Base-163.repo  install.log  vmware-tools-distrib
 
把CentOS-Base-163.repo 文件拷贝到 /etc/yum.repos.d/下改名为redhat-163.repo
cp CentOS-Base-163.repo redhat-163.repo

3：使用vim打开redhat-163.repo文件修改后的内容如下：

4：使用yum makecache 生成原数据缓存

5：使用yum update更新
以上是redhat配置网易163的yum源，这样就可以使用yum源了。
