Multi-version management of MySql: How to quickly manage multiple versions of MySQL

MySQL is a database management system widely used in various fields. During development, developers may need to use different MySQL versions for testing and development. However, how to easily manage multiple versions of MySQL is a challenge, especially when multiple versions are involved in a project.

This article will introduce some best practices for quickly managing multiple versions of MySQL.

1. Using a Virtual Machine

Using a virtual machine is one of the most common and easiest ways to manage multiple MySQL versions. Virtual machines allow us to run multiple operating systems simultaneously on a single computer, and each operating system can run a different MySQL version.

By using virtual machines, we can easily create and manage multiple MySQL instances without the need for complex management tools for a single instance. At the same time, virtual machines allow us to isolate different environments and not interfere with each other. Additionally, virtual machines make it easier to back up and restore MySQL instances.

2. Using plug-ins

MySQL provides a way to integrate plug-ins, which allows us to quickly run multiple MySQL versions on the same server. These plug-ins are MySQL version management tools that allow us to easily create, start and shut down multiple MySQL instances.

Specifically, we can use the MySQL-Sandbox plug-in to quickly create multiple MySQL instances. The plugin can specify a version, port number, and a different instance name for each instance. Using the MySQL-Sandbox plugin, we can create different MySQL instances for different projects and needs.

3. Using Docker containers

In addition to using virtual machines and plug-ins, we can also use Docker containers to manage multiple MySQL versions. Docker container is a lightweight application packaging and shipping tool that can run on any computer.

Using Docker containers, we can quickly create, maintain and share entire virtual environments, including MySQL. We can use Docker images to build MySQL instances. Each image can specify different MySQL versions and other configurations, and the container can be quickly started and stopped at any time.

4. Using Aliases

Another simple method is to use aliases to manage different MySQL versions. By setting aliases for each version, we can easily access specific MySQL versions at the operating system level.

For example, we can create an alias named "mysql56" pointing to the MySQL 5.6 installation path, and point the address of another alias "mysql57" to the MySQL 5.7 installation path. In this way, we can easily switch between different MySQL versions.

Summary

In this article, we covered best practices for managing multiple MySQL versions. Using virtual machines, plugins, Docker containers, and aliases are the most common ways to manage multiple MySQL versions.

By adopting these methods, we can easily create, start, stop, and manage different versions of MySQL instances, and be able to isolate and classify different environments and projects.
