想升级一下我的CentOS,提示:
[root@mail init.d]# yum update
Setting up Update Process
Setting up repositories
Cannot open/read repomd.xml file for repository: update
failure: repodata/repomd.xml from update: [Errno 256] No more mirrors to try.
Error: failure: repodata/repomd.xml from update: [Errno 256] No more mirrors to try.
[root@mail yum.repos.d]# cat CentOS-Base.repo正常,浏览mirror.be10.com发现无法访问,www.be10.com正常。
能ping通,发现80端口也开放,但是就是无法访问和升级。
