也可以直接 wget -c -r -np -e robots=off http://vault.centos.org/6/os/x86_64/
wget -c -r -np -e robots=off http://mirrors.sohu.com/centos/6/os/x86_64/
-c 断点续传
-r 递归下载,下载指定网页某一目录下(包括子目录)的所有文件
-nd 递归下载时不创建一层一层的目录,把所有的文件下载到当前目录
-np 递归下载时不搜索上层目录。
-e robots=off 忽略robots协议
1.同步源到本地服务器
rsync -avzLP --delete --exclude=SRPMS/ --exclude=x86_64/ --exclude=isos/ rsync://mirrors.sohu.com/centos/6.0/ /opt/centos/i386/
sohu的源同步好像有点慢,这里有个加拿大的源,速度还可以
rsync -avzLP --delete --exclude=SRPMS/ --exclude=x86_64/ --exclude=isos/ rsync://rsync.muug.mb.ca/centos/6.0/ /opt/centos/i386/
2.搭建本地web服务(apache)
3.编辑本地YUM服务器所使用的.repo文件 vim /etc/yum.repos.d/CentOS-Base.repo (当然,编辑之前最好备份一份)

说明: 上面的 192.168.5.30 是本地yum源服务器IP, gpgkey一定要是 RPM-GPG-KEY-CentOS-6,如果没有 请下载
wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
然后将这个新的 CentOS-Base.repo 下载到需要客户机上的/etc/yum.repos.d/ 下面, 执行 yum clean all , yum update 就可以升级了
就是如此简单.
