Bonjour,

Je ne parviens pas à installer un paquet sur ma machine RHEL7 (3.10.0-693.1.1.el7.x86_64). Voici la commande avec le message d'erreur.

_[root@rhtest ~]# yum install mysql-community-server-5.7.20-1.el7.x86_64
Config time: 0.004
Yum version: 3.4.3
rpmdb time: 0.000
Configuration du groupe de paquets
http://repo.mysql.com/yum/mysql-connectors-community/el/7/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: repo.mysql.com; Nom ou service inconnu"
Essai d'un autre miroir.

One of the configured repositories failed (MySQL Connectors Community),
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=mysql-connectors-community ...
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 mysql-connectors-community
or
subscription-manager repos --disable=mysql-connectors-community
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=mysql-connectors-community.skip_if_unavailable=true
failure: repodata/repomd.xml from mysql-connectors-community: [Errno 256] No more mirrors to try.
http://repo.mysql.com/yum/mysql-connectors-community/el/7/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: repo.mysql.com; Nom ou service inconnu"_

Avez-vous des pistes svp ?
Merci par avance.

    Les messages du type "Could not resolve host: …; Nom ou service inconnu" indiquent un problème de résolution de nom.

    Je viens d'essayer sur ma machine, le nom indiqué existe :
    $ host repo.mysql.com
    repo.mysql.com is an alias for repo.mysql.com.edgekey.net.
    repo.mysql.com.edgekey.net is an alias for e7528.d.akamaiedge.net.
    e7528.d.akamaiedge.net has address 23.212.225.186

    donc je soupçonne une mauvaise configuration de ta machine :
    - soit un souci dans la config dns
    - soit un souci dans la config réseau
