Linuxエラー・ノットの使用-yumのソフトウェア更新に失敗しました
3467 ワード
yumの使用条件:yumの使用はインターネットネットワークの接続を保証し、「cat/etc/resolv.conf」ファイルの下に「nameserver 8.8.8.8」が存在してこそ正常に更新できます.
または
ネットワークサービスを再起動し、「cat/etc/sysconfig/network-scripts/ifcfg-enp 0 s 3」ファイルを変更した後:
次のように構成されています(
confA1):
質問1:
設定:
構成:DNS=192.168.10.1
「cat/etc/resolv.conf」ファイルが次のように異常に更新されます.
# Generated by NetworkManager
# No nameservers found; try putting DNS servers into your
# ifcfg files in/etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com
解決1:
注記:「cat/etc/sysconfig/network-scripts/ifcfg-enp 0 s 3」ファイル:
#DNS=192.168.10.1
その後、ネットワークサービスを再起動して「サービスネットワークrestart」を有効にします.
そして、上記(
confA 1)の構成でOKが使えます.
質問2:
One of the configured repositories failed(不明)、
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:
....
Cannot find a valid baseurl for repo: base/7/x86_64
解決2:「cat/etc/resolv.conf」ファイルに「nameserver 8.8.8.8」を追加して解決します.
