Yum 卡在“设置更新过程”

运行以下命令时，yum 会挂起设置更新过程，然后服务器关闭，应从面板重新启动。centos 6.5 /etc/yum.conf

#  This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
#  It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).
# metadata_expire=90m

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

问题是什么 ？！

答案1

我相信您很可能有一个 NFS 挂载没有响应。当我的一个 NFS 挂载没有响应时，我也遇到了同样的问题。运行：

$ sudo mount

看看它是否挂起。如果是这种情况，您可能必须停止有问题的 nfs 客户端进程（终止该进程）。尝试查看哪个进程可能导致问题。

$ sudo lsof | grep nfs # or something that might yield nfs client file descriptors and their PIDs

然后从您的 中排除问题条目/etc/fstab。最坏的情况是，您可能需要尝试并使用 中的条目进行搜索/etc/fstab

我的看法。
