MySQL Configuration Wizard Updated

 | January 26, 2012 |  Posted In: Insight for DBAs, MySQL


We’ve released an updated version of the MySQL Configuration Wizard we announced at the end of last year. If you don’t remember that announcement, here’s the short version: this is a tool to help you generate my.cnf files based on your server’s hardware and other characteristics.

We’ve gotten really good feedback on this tool, including this nice mention on Stack Exchange:

Percona just built a tool to do just that called the Configuration Wizard. I tested it out once just to see what it would return and the results were pretty darn close to what we were using on our servers, whose cnf’s were put together by highly trained mysql certified dba’s.

So what’s changed in the new version of the Configuration Wizard? Quite a few things. We’ve rolled out the first iteration of the account and profile features. Now you get a homepage with your configuration files, so you can manage them and return to them anytime you like.

From this page (click on the image for a fullsize view) you can do things like sharing configuration files and emailing them to yourself. The new release also adds features like downloading the configuration files so you don’t have to copy-paste them.

If you share a configuration file, then the URL can be loaded by anyone, even if they’re not logged in. It’s kind of like sending someone a link to a pastebin or something like that. Screenshot:

Another new feature is something I’ve wanted for a long time: the ability to generate a more strict, safer configuration file. There’s a new page in the Wizard that lets you set a lot of sanity/safety options to prevent common problems MySQL users run into because of too-permissive MySQL behaviors. These are the kinds of things that Drizzle fixes — and should be fixed by default in MySQL — but never will be because they might break applications that rely on the default behaviors. If you’re building an application from the ground up, now you can prevent bad things from getting a nose under the tent. Here’s a screenshot:

In addition to these things, we have added a number of other features you might not notice, which I won’t spend much time on — they’re things like an integrated feedback form at the left of the page and so on.

What’s next? Well, next I think we’re going to turn our attention to adding new tools, rather than improving this one. I have a list of tools that people have requested or suggested: a SQL formatter, a visual EXPLAIN tool, a configuration advisor, a query analysis tool, a way to register a server’s essential characteristics and then get advice when there’s a new release that might be beneficial for you, and so on. I have selected the next priorities, but I don’t want to spoil the surprise or promise something if it turns out to be harder than I think it will be. What ideas do you have? Let me know by leaving your feedback in the comments.

We hope this suite of free browser-based tools helps you become a more productive MySQL user and administrator!
