Actually it’s pretty easy with Yum group install, a lot of people didn’t even notice this
$ sudo yum groupinstall "Tex Support"
There you go! run “tex” or “latex” in the shell and it’s up and running.
Sometimes you also need dvipng to compile Tex into PNGs
$ sudo yum install dvipng
Something about yum groups
if you want to see what packages is in this group, you can run:
$ sudo yum groupinfo "Tex Support"
If you want to see what other Package groups in yum, you can run
$ yum grouplist
