To get the open Fmaj9 tuning on your guitar you tune it like this: FACGAE.

Comments
Using F as the bass note will result in lots of chord possibilities with simple fingerings.
Obviously, there are many ways to play different F chords. Fmaj9 can also be played as 004030, 000030 and 034003, Fmaj7 can also be played as 000200, Fmaj13 can also be played as 002000, to name a few fingerings. There are also lots of alternatives for D minor with F as bass, for example Dm9/F can be played as 032200 as well as 002030. Notice also that Fmaj9 is theoretically identical with C6/F and Am7/F.
