In mysql master-slave Replication which server requests the other? I want to setup mysql replication between two servers one of them is my localhost and the other is online server.
I have all availability to make any one of them the master.
But according to that my localhost server doesn't have a static IP, i need to know which server of the two (master &amp; slave) is the one which requests the other for doing updates.
Does the master sends the binlog updates, or the slave is the one which requests for new updates periodically ? so i will make it the localhost.
thank you in advance.
according to this reference: Get MySQL Replication up and running in 5 minutes, Slave must access master to initialize.
slave&gt; CHANGE MASTER TO MASTER_HOST='192.168.0.31',
 -&gt; MASTER_USER='repl_user',
 -&gt; MASTER_PASSWORD='billy',
 -&gt; MASTER_LOG_FILE='',
 -&gt; MASTER_LOG_POS=4;

So, you can setup slave in localhost and master in remote host with accessible IP and port.
This is a client server communication:
