I think the command to use is chcon, although if you want this change to
persist re-labeling of the filesystem (which is regularly done in
postinstall when SELinux is enabled), you also need to use the
appropriate semanage fcontext incvocation. That's another reason not to
install things around the package manager on SELinux managed systems.

There's a number of primers and HowTos for SELinux, but it's
sufficiently complex that you should set up a throwaway system for
experiments before you let it loose. I'm not sure how different the SE
rule sets are for various distributions, the most widely used would
probably be RedHat/CentOS.
