[root@localhost yum.repos.d]# yum install **

yum安裝過程中報錯：repomd.xml: [Errno 14] HTTP Error 404: Not Found Trying other 解決辦法
查看/etc/yum.repos.d/CentOS-Base.repo 把裡面地址：
http://mirror.centos.org/centos/4/os/$basearch/
改成：
http://mirror.ce......
答案就在這裡：yum安裝過程中報錯：repomd.xml: [Errno 14] HTTP Error 404: Not Found Trying other 解決辦法
