Database replication in MySQL :: Master – Slave

I will try to describe how to set up database replication in MySQL. Replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. Today I will describe how to set up replication Master – Slave, next time – I will write about replication Master – Master. So let’s go.
