I have master-client replication system set up and the master data is being displayed in the client. Is there a way to sync the client details into mater?

Hi @Amrutha
I’m guessing you’re talking about MySQL Master-Slave Replication.
In that case, you should never write (INSERT or UPDATE) to your slave’s replicated database. You might end up breaking your replication.

Or did I misunderstand what you’re asking for?
Hi @hansen : Your understanding is correct.
According to the above link if we create a new database and tables in the slave, how could those details be displayed in the master?
You couldn’t - not with Master-Slave. Unless something has changed with MySQL, the replication is one-way for the entire server, even though it’s manually defined which databases are replicated.
If you want replication in every direction, then you should be looking at Master-Master replication, or maybe something like Galera if you want to expand to more than two database servers:

I have set up the master - master replication. So now when i create a table in master1 its getting displayed in master2, but when i create a table in master 2 it does not show up in master 1.
According to this master-master replication the data should travel both ways right?
@Amrutha
Can you post your configuration from both servers. And run this SQL query on both servers:
SHOW MASTER STATUS;
There’s a tutorial about Master-Master setup, but it’s old, but I still think you can skim through it and see if you’ve missed anything in your setup:
