(This resource is a configuration SOP for multi-machine and multi-user SSH certificate login authentication. It can basically be done by following this SOP. I spent 10 office days and searched a lot of information to no avail, and slowly experimented with self-sufficiency. Offer 6 beans. After downloading, please give more valuable comments, I will revise it, and then resubmit a new SOP.
