How to Achieve MySQL Database Synchronization with Replication?

MySQL Database Synchronization Between Two Databases

Challenge:

Centralize data management by keeping MySQL databases at multiple locations synchronized with a host server database.

Solution:

Configure MySQL Replication to establish a master-slave relationship, where:

• Master server: Receives updates (INSERT, UPDATE, DELETE) and writes them to the database.
• Slave server(s): Receives changes from the master and replicates them to their local databases.

Benefits of Replication:

• Keeps data on all connected databases up-to-date.
• Ensures high availability and data redundancy.
• Improves performance by distributing read queries across slave servers.

Steps to Configure Replication:

1. Set up a MySQL master server.
2. Set up one or more MySQL slave servers.
3. Configure the master server to allow replication.
4. Start replication on the slave servers.
5. Verify replication status and monitor servers for any issues.

Considerations:

• Avoid writing to the same tables on both the master and slave servers to prevent conflicts.
• Monitor your servers to ensure all data remains synchronized.
• Use tools or scripts to automate the replication process for ease of maintenance.
