MySQL Replication course from zero to hero | MySQL DBA

🚀 Master MySQL Replication & Database Administration Course 🎓

What You Will Learn in This Course

This comprehensive course is designed to take you from zero to hero in mastering MySQL Replication and becoming a proficient MySQL Database Administrator (DBA). You'll dive into the core concepts, explore different replication topologies, and gain practical skills for effective backup strategies and error resolution. Let's break down what you'll discover in this course:

• Understanding Replication: Learn about Master-Slave, Master with Multi-Slaves, and Master-Master replication setups. Each has its own advantages and use cases which we'll explore in detail.

• Advanced Replication Configuration: Get hands-on experience with various tools like mysqldump, extrabackup, xbstream, Mydumper, and the MySQL Clone plugin to set up and maintain your replication topology.

• Backup and Recovery Techniques: Understand how to take full and incremental backups with Extrabackup, and learn the steps to restore your databases from these backups while applying incremental changes.

• Replication Tuning: Discover how to configure Slave delay for controlling replication lag and optimize performance.

• Binary Log Formats: Learn about the different binary log formats (Row-based, Statement-based, Mixed mode) and how they affect your MySQL environment.

• Dealing with Replication Failures: Gain knowledge on handling failover scenarios, using pt-slave-restart to recover from errors, and troubleshooting errant GTIDs.

• Monitoring and Troubleshooting: Learn to read binary logs, check replication consistency, and use tools like pt-table-checksum and pt-table-sync for data integrity checks.

• Percona Monitoring and Management (PMM): Install and configure PMM for proactive monitoring of your MySQL environment.

• Multi Thread Slave (MTS) Configuration: Set up MTS for high-performance replication, check if workers are functioning correctly, understand the limitations, and create views for easier monitoring.

• Replication Orchestration: Configure orchestrator for failover scenarios, which is crucial for high availability setups. Note: Lectures on graceful failover and resolving errant GTIDs with Orchestrator are coming soon!

• Load Balancing with ProxySQL: Learn how to configure ProxySQL for load balancing, split read/write operations, and handle node failures effectively.
