Свежая установка CentOS 7.2.1511. Первоначально сервер был настроен с помощью Network Manager, а yum работал нормально. Недавно отключили Network Manager и настроили сеть с традиционным сервисом (/etc/sysconfig/network-scripts). Новые IP-адреса были назначены сетевым адаптерам. Первоначально программа установки была установлена в сети 10.xxx, а сейчас - в сети 192.168.xx.
Когда я пытаюсь запустить yum, я получаю следующую ошибку:
Loaded plugins: fastestmirror, langpacks
http://mirror.centos.org/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Trying other mirror.

Trying other mirror.
One of the configured repositories failed (CentOS-$releasever - Extras),
and yum doesn't have enough cached data to continue. At this point the only
safe 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 working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable extras
4. 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 much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=extras.skip_if_unavailable=true
failure: repodata/repomd.xml from extras: [Errno 256] No more mirrors to try.

Вот настройки для сетевых интерфейсов. em1 и em2 имеют одинаковую базовую конфигурацию:

PEERROUTES=yes

Мой файл /etc /hosts:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

Мой файл /etc/resolv.conf:
nameserver 68.105.28.12
nameserver 68.105.29.11
Мой файл CentOS-Base.repo. Я раскомментировал настройки baseurl, чтобы посмотреть, будет ли это работать:
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

Я уверен, что это как-то связано со старыми конфигурациями em1 и em2, когда они были связаны с разными IP-адресами, но я не знаю, где еще искать. Чего мне не хватает, что заставит тебя работать?
