Setup MySQL Master-Slave Replication

Setup MySQL Master-Slave Replication

Replication enables the data from one MySQL database server (master)to be copied to one or more servers ( slaves ). Learn how to Setup MySQL Master-Slave Replication.

Replication enables the data from one MySQL database server (master)to be copied to one or more servers ( slaves ). MySQL Replication is Async by default; slaves do not need to be connected permanently to receive updates from a source.

Replication can be configured for all the databases, selected databases, or even tables within the database

Advantages of replication

Scale-out — This will act as a load balancer for the MySQL server, the reads can be spread among the multiple replicas to improve performance. All writes will be performed on the master server and the reads may take place in one or more slaves. This will improve the Reads dramatically as it is spread across multiple nodes and also the writes as the master is dedicated for the Updates.

DR Copy — The replication can be used to set up the DR copy to the long-distance data server ( remote site )

Consistent Backup without Locking the Master Server: Replica nodes can be used to take the backup, the replica can be paused and take the backup and restart the process
