最近不知道是不是網(wǎng)絡的問題，在更新CentOS4.4的時候非常慢，等的我脖子都長的。
然后就自己把升級的腳本修改的一下，直接使用國內鏡像升級。速度非常快。
大家可以下載下面的文件進行替換，然后進行更新?；蛘呖聪旅娴男薷姆椒ò桑海?br />
1。修改升級腳本
#vi?/etc/yum.repos.d/CentOS-Base.repo
把mirrorlist=http://mirrorlist.centos.org.....開頭的行全部刪除.
接著把
http://mirror.centos.org/替換為
http://mirror.be10.com/接著把#baseurl=替換為baseurl=
接下來把$releasever替換成的你CentOS的版本，這里可以用4.4的更新.4.3的不支持。
最好是把$basearch替換成你的系統(tǒng)的相應的字竄。我的是i386的。服務器是x86_64的
大家按自己的情況替換就行了：）
