Achieving the best possible MySQL Performance doesn’t have to be complicated. It’s all about knowing which tools are designed for the task at hand – along with some basic (yet often overlooked) best practices.

Join me Wednesday, May 14 at 10 a.m. Pacific for a free webinar titled, “Practical MySQL performance optimization.” I’ll be sharing the main areas for improving MySQL performance – along with what to specifically focus on in each. These will include:

• Hardware
• MySQL Configuration
• Schema and Queries
• Application Architecture

And as I mentioned earlier, I’ll also show you the best tools for the job and how …

The Perfect Server - OpenSUSE 13.1 x86_64 (Apache2, Dovecot, ISPConfig 3)

This is a detailed description about how to set up an OpenSUSE 13.1 64bit (x86_64) server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable) with PHP, CGI and SSI support, Postfix mail server with SMTP-AUTH, TLS and virtual mail users, BIND DNS server, Pureftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, Mailman, etc. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache; this tutorial covers the setup of a server that uses Apache, not nginx.

When you use MySQL and PHP, a PHP script can retrieve data from a MySQL database to display on the web page before the page is returned to the client. Such pages are known as dynamic web pages and can perform multiple actions including sending e-mails, embedding other web page content and interacting with databases. 

To learn more about developing on the web with MySQL and PHP, take the MySQL and PHP: Developing Dynamic Web Applications course. You can take this 4-day live instructor-led course as a:

A while ago I wrote about some of the things that can make MySQL unreliable or hard to operate. Some time after that, in a completely unrelated topic, someone made me aware of a set of principles called 12-factor that I believe originated from experiences building Heroku.

That’s been over a year, and I’ve come to increasingly agree with the 12-factor principles. I guess I’m extremely late to the party, but making applications behave in 12-factor-compliant ways has solved a lot of problems for me.

This experience has repeatedly reminded me of one of the applications that continues to cause a lot of the kinds of pain that the 12-factor principles have solved for me: MySQL.

Example: configuration files. I initially thought MySQL’s technique of multiple configuration files …

SELF14′s Zero to DBA track is back and starts with MySQL 5.7 – What is new, what is changing, and what we are breaking. The SouthEast Linux Fest has had amazing sessions and a strong database track in previous years. This year is more great content and you really need to plan on attending June 20th through the 22nd on Charlotte, NC. The social events around this show are fun and relaxed. And, after a short delay, you can see all sessions on SELF’s Youtube channel so you can really see sessions that conflict with your primary choices. This year the venue has changed to a more central location near the airport and their are lots of activities in the area for your family to enjoy in the beautiful surrounding while you get your tech itch scratched.

Background: If you did not read my first blog post about why I am sharing my thoughts on the benchmarks published by Mark Callaghan on Small Datum you may want to skim through it now for a little context: “Thoughts on Small Datum – Part 1”

Last time, in “Thoughts on Small Datum – Part 2” I shared my cliff notes and a graph on Mark Callaghan’s (@markcallaghan) March 11th insertion rate benchmarks using flash storage media. In those tests he compares MySQL outfitted with the …

Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support (LEMP) On Ubuntu 14.04 LTS

Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on an Ubuntu 14.04 server with PHP5 support (through PHP-FPM) and MySQL support (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP) .
