![]() ![]() Each servers firewall should allow traffic on ports.Connectivity to install packages using yum or through corp proxy if any.Minimum 2 Nodes – one master & one slave.For the tutorial purpose, we will use three Nodes for the MySQL replication cluster. In this tutorial, we will explain the step by step guide for setting up a MySQL master-slave replication. Here is a reference architecture of a replication cluster with ETL, reporting and backup use cases. In an event of regional failures, we can bring up the database in a different region with the help of replication slave. For disaster recovery, replication is a great fit as you can set up a replication slave in a different region which asynchronously gets the master data.Replication allows you to reduce the load from the master as the replication slave will be involved in serving the application requests.Backup solutions like mysqldump can cause locking problems when the backup is being done.This architecture is suitable for scaling MySQL with many read slaves.So this strategy can be used for business systems which can afford a small interruption. If the master goes down, there needs to be some work done to get another slave as a master. You can add more read replicas to improve the read throughput as your business grows.In asynchronous replication write latency is lower as the writes are acknowledged by master locally.Replication can be Asynchronous or Semi-Synchronous. ![]() The relay log is read by the SQL thread process and it applies all the operations/data to the slave’s database and its binary log.Slaves then apply the binary log to its realy log.The slave servers get the masters binary log.Salves connect to the master and asks for the data.All database operations are copied to the master’s binary log.In this section, we will look at the MySQL replication architecture and how it works. MySQL Master-Slave Replication Architecture In such cases, a MySQL master-slave replication offers data replication on multiple nodes for scalability and data availability. ![]() However, due to data compliance, and other audit requirements, we will have to choose self-managed solutions. In the era of cloud computing, there are many managed MySQL solutions available. ![]()
