"Could not resolve host: mirrorist.centos.org: Unknown error"
One of the configured repositories failed (Unknown),
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 "Pix" this
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurletc. 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 land the packages for the previous distribution release still work).
3. Run the conmand with the repository temporarily disabled
ЦшМ
--disablerepo=crepoid>
4. Disable the repository permanently, so yum won't use it by default. Yum will them just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable crepoid>
Or subscription-manager repos --disable=crepoid>

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 land 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=crepoid>.skip_if_unavailable=true
