【江湖救急】yum 不能用

beyond_dream

服务器WIN系统被黑了
换了centos5.2
不是很熟悉
望达人指教；
错误情况如下：

[root@localhost ~]# yum -y install httpd
Loading "installonlyn" plugin
Setting up Install Process
Setting up repositories
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=extras error was
[Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
Error: Cannot find a valid baseurl for repo: extras

[root@localhost ~]# rpm -ivh yum*.noarch.rpm

在线等。。。。。。。。

在一位大哥的帮助下，把下面的2句
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
换成了  #号的位置互换了
mirrorlist=http://centos.ustc.edu.cn//?release=$releasever&arch=$basearch&repo=os
#baseurl=http://centos.ustc.edu.cn//centos/$releasever/os/$basearch/


结果报下面的错误：
[root@localhost ~]# yum update
Loading "installonlyn" plugin
Setting up Update Process
Setting up repositories
http://centos.ustc.edu.cn/centos ... epodata/repomd.xml: [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
Trying other mirror.
Error: Cannot open/read repomd.xml file for repository: extras

添加163的源
yum clean all先
然后再yum update

failure in name resolution'

将mirror.centos.org换成mirrors.163.com这个是比较快的
