By sailing through the narrow space in between them. By sailing closer to Scylla, he saved his ship, but lost 6 men in the process.
Odysseus chooses to pass by Scylla because, Scylla will only kill 6 men, one for each head. Charybdis will sink the ship, killing everyone. Circe has also advised Odysseus to do choose Scylla. Further, Charybdis is a visible danger, and Odysseus uses Charybdis to encourage his men to pass by quickly. Finally, passing by Scylla and Charybdis is given as the only way for Odysseus to get home from where he is.

Scylla And Charybdis
scylla and charybdis
The strait is narrow and so Odysseus has to pass by either Scylla or Charybdis. Circe tells Odysseus that Charybdis is far more dangerous, as 3 times a day it sucks in all the waters around it. This would completely suck in Odysseus and his ship if he is sailing too close to Charybdis. Circe advises Odysseus to go to Scylla's side of the strait, for despite the danger of the monster, it is preferable to lose a half-dozen men than the whole ship.
Odysseus donned his armor and readied his spear to attempt to fight of Scylla. He then ordered his men to hug the rocks, where Scylla was, as to avoid Charybdis. He was unable to prevent the capture of his 6 men.
Odysseus successfully sailed his ship past Scylla and Charybdis, but Scylla managed to catch six of his men, devouring them alive.
