I try to setup the multi-source replication and I read that tutorial : http://mysqlhighavailability.com/mysql-5-7-multi-source-replication-automatically-combining-data-from-multiple-databases-into-one/
I think I've found exactly what we are looking for! But I'm a newbie in replication. I have to do it for my work and I really don't know from what I have to start from what! This is my first time I’m trying to configure a MySQL replication.
We have 2 (later we will have more, they will be added in the future, one by one) servers (masters) which will be installed on external IP (different customers office) and 1 "main server" (slave) installed on a "web server" (don’t know where for the moment).
All the databases have the same name.
MASTERS
Office #1 (New York) -> database : test
Office #2 (Fort Lauderdale) -> database : test
Office #3 (Chicago) -> database : test
SLAVE
WebServer (San Diego) -> database : test
What is the first step? It looks like I miss something when I try to configure it using the link above.
Do I have to setup "regular" replication master-slave before and after modify it to make it works as multi-source replication? I'm lost and I don't find a lot of documentation about this. Does someone can help me please?
