It's both formal and informal. It depends on how you say it. If you say "Adiós, señora." it's formal. If you say "Adiós, amigo." it's informal.
If you know the person or are being introduced, you're also expected to either faire la bise (kiss cheeks) if you are familiar with that person or se serrer la main (shake hands). When arriving at work or school, this means you should go around the room and individually greet each person. Formal greetings are for older people or people that you respect.
