Свіжа установка CentOS 7.2.1511. Спочатку сервер був налаштований за допомогою Менеджера мережі, і ви працювали чудово. Нещодавно відключений Менеджер мереж та налаштована мережа з традиційною службою (/ etc / sysconfig / network-script). Новим ІР-адресам було призначено NIC. Спочатку налаштування було в мережі 10.xxx, зараз у мережі 192.168.xx.
Коли я намагаюся запустити yum, я отримую таку помилку:
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.
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.

# 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

Я впевнений, що це має щось спільне зі старими конфігураціями em1 та em2, коли вони були пов'язані з різними IP-адресами, але я не знаю, де ще шукати. Що я можу бракувати, що змусить вас працювати?
