Nova instalação do CentOS 7.2.1511. O servidor foi originalmente configurado com o Network Manager e o yum estava funcionando bem. Recentemente desativei o Network Manager e configurei a rede com serviço tradicional (/etc/sysconfig/network-scripts). Novos endereços IP foram atribuídos às NICs. A instalação estava originalmente em uma rede 10.xxx, agora está em uma rede 192.168.xx.
Quando tento executar o yum, recebo o seguinte erro:
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.

Meu arquivo CentOS-Base.repo. Descomentei as configurações de baseurl para ver se funcionaria:
# 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.

Tenho certeza de que isso tem algo a ver com as configurações antigas de em1 e em2, quando estavam vinculados a endereços IP diferentes, mas não sei mais onde procurar. O que posso estar faltando para fazer o yum funcionar?
Responder1
Depois de mais investigações, descobri. Faltava uma hierarquia de diretórios e o yum não conseguiu detectar minha versão do CentOS. A execução dos seguintes comandos corrigiu tudo:
mkdir -p /etc/yum/vars
echo 7.2.1511 > /etc/yum/vars/releasever
Substitua "7.2.1511" pela sua própria versão se você estiver tendo esse problema e nada mais funcionou.
ATUALIZAÇÃO 21/05/2017: O caminho "7.2.1511" foi descontinuado. Execute o seguinte comando para manter o yum funcionando se você ainda estiver no CentOS 7.2.1511:
echo 7 > /etc/yum/vars/releasever
Isso deve resolver o problema, caso você descubra de repente que o yum parou de funcionar.
Responder2
Uma solução alternativa é executar o seguinte comando.
rm -fr /var/cache/yum/x86_64/7
yum clean all
Isso funcionou para mim. CentOS Linux versão 7.2.1511 (núcleo)
