valid - centos 7.1-repositorio de errores

errno 14 curl 6 could not resolve host

Question

Hola, he descargado la versión mínima de CENTOS 7 en este enlace de URL descarga ISO centos 7.x

Todo funciona correctamente ... el PING y la red están bien. Hago ping al HOST externo, por ejemplo.

Pero cuando digito:

[root@localhost ~]# yum update
Loaded plugins: fastestmirror
One of the configured repositories failed (Unknown),
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 <repoid>
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=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64

¿Por qué?

This is another command:
root@localhost ~]# yum repolist all

Answer 1

Es el error que proviene de la conexión https en /etc/yum.repos.d/epel.repo después de que instaló ius-release.rpm a través de

sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm

Debes hacer lo siguiente en /etc/yum.repos.d/epel.repo .

baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch

baseurl y línea de comentario que comienza con mirrorlist= .

Answer 2

baseurl en este archivo: /etc/yum.repos.d/CentOS-Base.repo

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

En este bloque:

[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

Por comentario, me refiero a cambiar esto: #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ , a esto: baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ (eliminar el # ).

Answer 3

El problema es la configuración de dhcp, intenta escribir

dhclient

Answer 4

Verifique su resolv.conf para ver a dónde apunta su servidor de nombres. Asegúrate de que sea algo legítimo ya que el mío apuntaba a un antiguo servidor DNS en la red que fue aniquilado. Lo actualicé con la nueva dirección IP et voila!

Answer 5

En primer lugar, pude solucionar este problema como se mencionó anteriormente mediante el uso de "dhclient". Pero tendrá que ejecutar este comando cada vez que reinicie. Esto podría deberse a que su Ethernet está deshabilitada y debe habilitarla explícitamente. Haga clic aquí para ver el motivo . Para una solución permanente edité / etc / sysconfig / network-scripts / ifcfg- {YOURETHERNET} (en mi caso fue / etc / sysconfig / network-scripts / ifcfg-eth0) y cambié ONBOOT = yes y boom !!!

Answer 6

Aterricé aquí porque había agregado un espejo defectuoso para una dependencia diferente (pasajero, para una aplicación de Rails) y resolví este problema simplemente borrando el espejo defectuoso:

rm /etc/yum.repos.d/YOUR-BAD-DEPENDENCY-NAME.repo

p.ej

rm /etc/yum.repos.d/passenger.repo
