CentOS 7 Kann keine gültige Baseurl für Repo finden: base / 7 / x86_64 Beim Aktualisieren des Yum

Dieser Fehler macht mich verrückt, ich habe alles versucht, was in den Foren gepostet wurde und nichts funktioniert.

Wenn ich tippe:

# yum update

Ich erhalte folgende Fehlermeldung:

[root @ www yum.repos.d] # Aktualisierung von yum Aktualisierungen Komplementärs cargados: fastmirror Laden der Spiegelgeschwindigkeiten aus dem zwischengespeicherten Hostfile Spiegelliste konnte nicht abgerufen werden http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock Fehler war 14 : curl # 56 - "Recv-Fehler: Verbindung wurde von Remote-Rechner zurückgesetzt"

Eines der konfigurierten Repositorys ist fehlgeschlagen (Unknown) und Yum verfügt nicht über genügend zwischengespeicherte Daten, um fortzufahren. An diesem Punkt ist das einzig sichere, was yum tun kann, scheitern. Es gibt einige Möglichkeiten, um das Problem zu beheben:

 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. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ...  4. Disable the repository permanently, 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> or subscription-manager repos --disable=<repoid>  5. 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 

Eine gültige Baseurl für Repo kann nicht gefunden werden: base / 7 / x86_64

Es ist ein Produktionsserver mit einer eigenen IP-Adresse, daher habe ich DHCP nicht versucht und ONBOOT = no (ich habe es ja), usw.

Wenn ich tippe:

# curl -v 'http://mirrorlist.centos.org/?repo=os&arch=x86_64&release=7'

Das bekomme ich:

[root@www yum.repos.d]# curl -v 'http://mirrorlist.centos.org/?repo=os&arch=x86_64&release=7' * About to connect() to mirrorlist.centos.org port 80 (#0) * Trying 2001:1b48:203::4:10... * Connected to mirrorlist.centos.org (2001:1b48:203::4:10) port 80 (#0) > GET /?repo=os&arch=x86_64&release=7 HTTP/1.1 > User-Agent: curl/7.29.0 > Host: mirrorlist.centos.org > Accept: */* > * Recv failure: Connection reset by remote machine * Closing connection 0 curl: (56) Recv failure: Connection reset by remote machine

Wie kann ich wieder yum updatearbeiten?
