1. On each server, execute the SET @ @GLOBAL. Enforce_gtid_consistency=warn; Make sure there is no WARN "warning" in the errorlog, if you have to fix it then proceed again.

3. On each server, execute the SET @ @GLOABL. gtid_mode=off_permissive; This step has nothing to do with the execution of the server, so be sure to do so after all the servers have been kept in check.
