    What about the config file parameters that need to be setup before the replication can begin?

    I liked it but though it oversimplified some things. For example the instructor used the root user a lot  which in practical practice is a huge security  no no.
    Also the example did not explain how different configurations or states of the slaves would be effected. For example  can I assume as I have that this tool replicates every database and every table or replicable Storage Engines ?
    What would happen if I was missing any  tables in each of the databases would that effectively copy over just the updates and inserts from the time replication begins or would it synchronize each and all tables??

    For example   if I were replicating a single database innoworld  and I only had City table in my slaves and  all tables in my master what would happen? Would those first checks have failed  or would  the tables be copied to sync up the tables?
    My first thought is no syncing up of tables I must have all the tables defined and only transactions starting when the slaves are started are handled.
    Still it would be good to understand how the failover  utility works internally  which it presumably  does by  keeping track of all the information you shared in those preceding commands. Still those file position issues appear to be handled – where are they handled in the actual mysqlreplicate command?
    Is that where  the master.info  information is essentially handled?
    and the CHANGE TO MASTER commands automatically created and executed in each slave using the original master?

    I think this demo is really confusing with the same names for each server and different ports.
