CentOS - How to uninstall package installed by rpm

I had installed openvpn via rpm on my CentOS 6.5 OS.  To uninstall it, you must know the exact package name.

1. Issue "rpm -qa" and grep for what your package name may contain
• $ rpm -qa | grep openvpn
  openvpn-as-2.0.20-CentOS6.4.x86_64
2. Issue rpm -e to remove the exact package name
• $ sudo rpm -e openvpn-as-2.0.20-CentOS6.4.x86_64
