Hyper-V上にCentOS7の環境を作ってyumコマンドを使用したいのですが、
コマンドをたたくと下記のエラーが出ます。
[root@hoge01 ~]# yum update
読み込んだプラグイン:fastestmirror, langpacks
Determining fastest mirrors
__Could not retrieve mirrorlist http://mirrorlist.centos.org/?__release=7&arch=x86_64&repo=os&infra=s... error was
14: curl#7 - "Failed connect to mirrorlist.centos.org:80; 現在処理中の操作です"
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:
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
Cannot find a valid baseurl for repo: base/7/x86_64
ネットで調べるとDNSの設定がされていないのが原因とあり
下記ファイルにそれぞれ追記してネットワークを再起動したのですが
やはり上記とうまくいきません。
参考URL:https://qiita.com/ntkgcj/items/fd8588dcd65a42c34875
/etc/sysconfig/network-scripts/ifcfg-eth0
DNS=8.8.8.8
/etc/resolv.conf
nameserver 8.8.8.8
どうしたらyumが使用出来るようになるかご教示頂けたらと思います。
エンジニアとしてはまだ駆け出しで基礎が分かっていないことが多いのですが
宜しくお願い致します。
