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 & 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> CHANGE MASTER TO MASTER_HOST='192.168.0.31', -> MASTER_USER='repl_user', -> MASTER_PASSWORD='billy', -> MASTER_LOG_FILE='', -> 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:
