First, check the error log, if you can't find it, start mysql from the cmd line by running safe_mysqld it should print errors to console.
If it is a permission issue, it might be caused be selinux, you'll need to change the object type od that new directory to mysqld- something. I can't recall the command. A google search on selinux and mysql should produce good results.
