DevOpsDays Toronto: Community, Collaboration and Supporting the change in IT

ProxySQL Admin Interface Is Not Your Typical MySQL Server!

In this blog post, I’ll look at how ProxySQL Admin behaves in some unusual and unexpected ways from a MySQL perspective.

ProxySQL allows you to connect to its admin interface using the MySQL protocol and use familiar tools, like the MySQL command line client, to manage its configuration as a set of configuration tables. This ability may trick you into thinking that you’re working with a stripped-down MySQL server – and expect it to behave like MySQL. 

It would be a mistake to think this! In fact, ProxySQL embeds the SQLite database to store its configuration. As such, it behaves much closer to SQLite!

Below, I’ll show you a few things that confused me at first. All of these are as of ProxySQL 1.3.6 (in case behavior changes in the future).

MySQL Documentation: Syntax Highlighting

MySQL documentation has much improved code examples now: There's syntax highlighting in place, and code snippets can easily be copied to the clipboard. Highlighting is language-aware (including "languages" like the shell/command line). See, for example, this page from the X DevAPI documentation that contains a number of code examples for different programming languages.

Syntax highlighting is a project we planned a year ago, but it turned out to be more complex than we thought it would be. One of the major challenges was performance -- we didn't want the new function to slow down page loading, which is what many highlighting plugins do. Eventually, our striving Web team gave prism.js a try, which works like a charm and doesn't impact performance at all. The Web team also created a little …

MySQL Encryption at Rest – Part 1 (LUKS)

In this first of a series of blog posts, we’ll look at MySQL encryption at rest.

At Percona, we work with a number of clients that require strong security measures for PCI, HIPAA and PHI compliance, where data managed by MySQL needs to be encrypted “at rest.” As with all things open source, there several options for meeting the MySQL encryption at rest requirement. In this three-part series, we cover several popular options of encrypting data and present the various pros and cons to each solution. You may want to evaluate which parts of these tutorials work best for your situation before using them in production.

Part one of this series is implementing disk-level encryption using crypt+LUKS.

In MySQL 5.7, InnoDB has built-in encryption features. This solution has some cons, …
