It seems Yum is broken and I don't know why. Previously it was working fine when I installed httpd mysql and all the other stuff. Would be really grateful if anyone can help. Thanks!

Try after erasing yum plugins like yum-tmprepo ... maybe fastestmirror

What happens with
yum check
yum update

I was facing this problem couple of time before , sometime just after start of my pc , i mess with this problem alot sometime i mess with this problem with couple of days and finally i got the solution, i just restart my pc and and this problem will no more, i think u should do this . because what i thing your yum command is not working , try use only yum on the terminal and then enter.

OP is manually running yum... the only other way is to schedule a job.
The problem relates to some yum plugin.
