技术咨询：MySQL InnoDB Cluster是否可免费获取？

Hey there, let me clear up this confusing situation for you—InnoDB Cluster is absolutely part of the free MySQL Community Edition, no paid enterprise subscription required. That weird redirect to NDB Cluster docs is almost certainly a navigation bug on the MySQL website, not a sign that InnoDB Cluster is locked behind a paywall.

Here’s a breakdown to set things straight:

• InnoDB Cluster comes included with MySQL Community Server 8.0 and newer. You don’t need to pay a dime to access or use it for your high-availability setups.
• The management tools for it—like MySQL Shell and MySQL Router—are also free community tools, either included in the main server installer or available as separate free downloads.
• NDB Cluster is a totally separate component (built for distributed, shared-nothing high availability), so the redirect you hit is just a site error, not an indication that InnoDB Cluster is tied to enterprise plans.

To get started with InnoDB Cluster:

1. Grab the latest MySQL Community Server from the official downloads page (double-check you’re picking the "Community" option, not Enterprise).
2. Make sure you have MySQL Shell installed (it’s often bundled with the server, but you can download it separately if needed).
3. Follow the official community documentation to set up your cluster—no paid licenses or 5000-dollar plans required.

I’ve seen other community users report this same confusing redirect issue before, so you’re not alone. The core takeaway is that InnoDB Cluster remains a free, fully supported part of the MySQL Community ecosystem.
