I got installation hanged after this:
Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile
so I checked if network is ok
nslookup ya.ru
it’s ok
then I removed fastestmirror cache and got things working
rm -f /var/cache/yum/timedhosts.txt
My main background for a recent years is MySQL DEV/DBA engineer but I’m also participating in wider range of tasks which could be likely called as DataOps/DevOps tasks. You can see my online CV here: http://catyellow.net
