The latest from the MySQL community

It’s been written about everywhere, but since we keep spotting installations in the wild where people don’t know about it, it probably deserves another mention.

By default, Linux uses the atime option on a disk mount, which means it writes a timestamp (e.g. a write to the drive) every time it reads anything. So in this case, reads cause writes – and also disk seeks, because a read from a file will then trigger having to write to the directory that contains the file. This even occurs if a file is read from the file system’s page cache (reading from the machine’s memory rather than the drive).

Unless you require an audit trail of users reading files, you generally you don’t want this. Thus, you want to add the noatime option to the disk mount in /etc/fstab. If you have just the defaults in there, you just make it defaults,noatime. It’ll doesn’t necesarily require a reboot as you …

Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support (LEMP) On Ubuntu 12.10

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 12.10 server with PHP5 support (through PHP-FPM) and MySQL support (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP).

I was lucky enough to attend PyCon-AU recently and one talk in particular highlighted the process of web server optimisation.

Graham Dumpleton’s add-in talk Web Server Bottlenecks And Performance Tuning available on YouTube (with the majority of PyCon-AU talks)

The first big note at the beginning is that the majority of the delay in user’s perception of a website is caused by the browser rendering the page. Though not covered in the talk for those that haven’t used the tool YSlow (for Firefox and Chrome) or Google’s Developer Tools (ctrl-alt-I in Chrome), both tools will …

Configuring Your LEMP System (Linux, nginx, MySQL, PHP-FPM) For Maximum Performance

If you are using nginx as your webserver, you are looking for a performance boost and better speed. nginx is fast by default, but you can optimize its performance and the performance of all parts (like PHP and MySQL) that work together with nginx. Here is a small, incomprehensive list of tips and tricks to configure your LEMP system (Linux, nginx, MySQL, PHP-FPM) for maximum performance. These tricks work for me, but your mileage may vary. Do not implement them all at once, but one by one and check what effect the modification has on your system's performance.

If you use PrestaShop and nginx, you may find this script to convert PrestaShop’s .htaccess rules into an nginx rule file useful:

#!/usr/local/bin/perl
print <<EOF;
fastcgi_buffers           16 128k;
fastcgi_busy_buffers_size 128k;
fastcgi_buffer_size       128k;
client_body_buffer_size   128k;
EOF
while (<>) {
    if (/^RewriteRule \^(.*) \[L\]$/) { print "rewrite ^/$1? break;\n"; }
    if (/^RewriteRule \^(.*) \[QSA,L\]$/) { print "rewrite ^/$1 break;\n"; }
    if (/^ErrorDocument (\d+) (.*)$/) { print "error_page $1 = $2;\n"; }
}

Save as convert-htaccess.pl and run with ./convert-htaccess.pl <.htaccess >.htaccess.nginx. Then don’t forget to include .htaccess.nginx into your nginx site configuration and reload nginx.

If you have multiple languages or an other configuration that includes { brackets }, you may have to adapt the script.
