J'utilise Centos 6.6 (x86_64) en essayant d'installer la version mongodb la plus stable disponible. mais je suis coincé avec cette erreur (qui peut sembler répétée mais aucune des réponses précédentes n'a fonctionné pour moi)

#  This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
#  It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).
# metadata_expire=90m
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

S'il vous plaît, aidez-moi à comprendre cela!
J'ai également mis SELinux = permissive Après avoir corrigé les erreurs qui ont pointé sim, j'obtiens l'erreur suivante
