I want to have a clone of a postgresql database. If I copy the entire data directory from one machine and replace another machine’s data directory with it, will there be any problems? both of them have the same OS, btw (CentOS)

Certainly if you stop the server and then copy it, that’s fine. If you don’t, the cloned server will have to do recovery, which isn’t so good. Or just use pg_dumpall to produce a script to recreate the data on the new machine.
