At this point the onlysafe thing yum can do is fail. There are a few ways to work "fix" this:1. Contact the upstream for the repository and get them to fix the problem.2. Reconfigure the baseurl/etc. for the repository, to point to a workingupstream. This is most often useful if you are using a newerdistribution release than is supported by the repository (and thepackages for the previous distribution release still work).3. Run the command with the repository temporarily disabledyum --disablerepo=centos ...4. Disable the repository permanently, so yum won't use it by default. Yumwill then just ignore the repository until you permanently enable itagain or use --enablerepo for temporary usage:yum-config-manager --disable centosorsubscription-manager repos --disable=centos5. Configure the failing repository to be skipped, if it is unavailable.Note that yum will try to contact the repo. when it runs most commands,so will have to try and fail each time (and thus. yum will be be muchslower). If it is a very temporary problem though, this is often a nicecompromise:yum-config-manager --save --setopt=centos.skip_if_unavailable=truefailure: repodata/ce678501a07f940dbe16d3e4fcb495050fd48ec429c5e8ea955e681594f90934-filelists.sqlite.bz2 from centos: [Errno 256] No more mirrors to try.file:///mnt/repodata/ce678501a07f940dbe16d3e4fcb495050fd48ec429c5e8ea955e681594f90934-filelists.sqlite.bz2: [Errno 14] curl#37 - "Couldn't open file /mnt/repodata/ce678501a07f940dbe16d3e4fcb495050fd48ec429c5e8ea955e681594f90934-filelists.sqlite.bz2"
解决方案：
ping网络没有问题
ping PING www. (220.181.38.150) 56(84) bytes of data.64 bytes from 220.181.38.150 (220.181.38.150): icmp_seq=1 ttl=50 time=21.3 ms64 bytes from 220.181.38.150 (220.181.38.150): icmp_seq=2 ttl=50 time=21.8 ms^C
查看是不是yum源问题
vim /etc/yum.repos.d/centos.repo
yum源已配置没有问题 ，若未配置则需创建centos.repo
查看sro是否挂载
df -h
挂载失败，手动挂载
mount /dev/cdrom /mnt
