![]() ![]() For Public access, on the Networking page, under Firewall rules, ensure that the primary server firewall allows connection from the replica server by verifying that the Allow public access from any Azure service… check box is selected.Ensure that networking is configured such that primary server and replica server can communicate with each other.During the migration, depending on the amount of data, the value can vary from 1 day to 3 days (converted to seconds). In the Azure portal, in the server parameters section, set the ` binlog_expire_logs_seconds ` parameter on the primary server to ensure that binlogs aren’t purged before the replica commits the changes.Ensure that the log_bin parameter is set to ‘ON’.Ensure that the user account involved in the replication has ‘replication slave’ privileges for all tables and databases.I’ve created a custom database named ‘ db1’ in the primary server for testing this replication. You can download mysqlsampledatabase.zip, and then run the included script on the primary server to create the sample classicmodels database. A sample database for testing replication. ![]() Note: After replication is set up and the migration completes, you can delete this VM. For more information about this tool, see MySQL :: MySQL Shell 8.0. MySQLsh – Download the mysqlsh client from.MySQL client – If it isn’t installed by default, download it from MySQL :: MySQL Community Downloads.Ensure that the VM has the following client tools installed: An Azure VM running Linux that can connect to both the source and target servers.Note: For information about creating an instance of MySQL – Flexible Server, see Create an Azure Database for MySQL flexible server. An Azure Database for MySQL single server (the replication source) and an Azure Database for MySQL flexible server (the target), each running the same MySQL version (5.7 or 8.x).When the term is removed from the software, we'll remove it from this article.īefore starting this process, be sure that the following prerequisites are in place. Note: This article references the term slave, which Microsoft no longer uses. The following sections provide detail about each of these stages. Configuring Data-in replication between the source (Single Server) and target (Flexible Server).The overall migration process includes the following high-level stages: However, selecting the best tool to address a specific migration scenario is a critical first step in the database migration journey, so be sure to refer to the blog post Selecting the best tool for migrating to Azure Database for MySQL – Flexible Server to understand the options available for your scenario. Note: MySQLsh can also be used to migrate from VM, on-premises, different cloud vendors to Azure database for MySQL flexible server. This tool has shown promising results when used in a variety of scenarios with different database sizes. Mysqlshell, or ‘mysqlsh’, uses parallelism, which can speed up both the backup and restore process. In this blog post, I’ll explain how to migrate from Azure Database for MySQL - Single Server to Flexible Server with minimal downtime by using the ‘mysqlshell’ tool, an alternative to the mydumper/myloader tool. Using Data-in replication also allows you to achieve minimal down-time for migrations from Single Server to Flexible Server. The external server can be running on-premises, in virtual machines, in Azure Database for MySQL - Single Server, or even in a database service hosted by other cloud providers. You can use Data-in replication in Azure Database for MySQL – Flexible server to synchronize data in an external MySQL server with an Azure Database for MySQL flexible server. We're now focusing all energies and feature investments towards Flexible Server, with Azure Database for MySQL - Single Server on path for retirement on 16 September 2024. Our flagship offering, Azure Database for MySQL – Flexible Server, is well-positioned to serve as the best platform for hosting your MySQL workloads, offering maximum control and flexibility to run your MySQL servers. MySQL is an advanced, feature-rich, open-source database system that’s popular with developers, used for a wide range of applications, and compatible with the most popular application platforms. Azure Database for MySQL is a relational database service in the Microsoft cloud that is based on the MySQL Community Edition database engine. ![]()
