sudo -u ceph ceph-mon -i mon2 --mkfs --monmap /tmp/monmap.map
chown -R ceph:ceph /var/lib/ceph/mon/ceph-mon2
systemctl start ceph-mon@mon2
I'm missing the part where keyring is downloaded and used:
ceph auth get mon. -o /tmp/keyring
ceph mon getmap -o /tmp/monmap
chown -R ceph:ceph /var/lib/ceph/mon/ceph-mon2
ceph-mon -i mon2 --mkfs --monmap /tmp/monmap --keyring /tmp/keyring
--setuser ceph --setgroup ceph

P.s. I have noticed, that sometimes you first need to reboot the node
before you are able to start the monitor with systemd.
