How to resolve MySQL and FK réplication problem?

Question

I'm looking to create a replication server. Dump is ok, database master too. I imported dump but replication doesn't work.

here is the slave status :

I don't know what I have to change. especially since the master base is in production, so impossible to modify it (and anyway, it works very well) Does someone can help me ?

Answer 1

First disable the FK, see below

SET FOREIGN_KEY_CHECKS=0
... import it ...
SET FOREIGN_KEY_CHECKS=1
