Could not retrieve mirrorlist http:
//mirrorlist
.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl
#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"
One of the configured repositories failed (未知),
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. Disable the repository, 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
4. 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=
true
