Configuring Lighttpd for WordPress with Rewrites

Today I had to configure a WordPress website to use Lighttpd. I looked for the proper rewrites to use and only received garbled information about the rewrites. So instead of forgetting it again for the umpteenth time, I will post my getting WordPress to work with Lighttpd tips / tricks here.

First up there are three key rewrites to get Lighttpd to work with WordPress. They are as follows: (note mod_rewrite will need to be enabled and this is in the lighttpd.conf).

url.rewrite = (
        "^/(wp-admin|wp-includes|wp-content)/(.*)" => "$0",
  "^/(.*).(.+)$" => "$0",
  "^/(.+)/?$" => "/index.php/$1"

The second key item is making sure that the error handler is set properly.… Read More

Trick for Apache2 and MySQL Crashing on High Load / Apache Benchmark

In the past, I have given some thought to a high load but not very much. For the most part having Lighttpd and Varnish in front of my Web servers alleviates most problems. That is until the other day when I decided to do an Apache benchmark test on my system and was able to bring down the server. The load made MySQL go insane by inflating it to 200% CPU usage! To make my servers available again I had to basically restart MySQL. This is not a huge issue, mainly because we do not have a high load but it was concerning.… Read More

Stop Crontab from Sending Emails

This week I was starting to get fed up with Crontab and it always sending me emails regarding jobs. I have log files setup and prefer to look at my logs for errors vs crontab flooding my inbox. I never can seem to remember the 2>&1 trick, as I do not constantly use crontab. So I went exploring in the manual and found a nice little track to stop crontab from flooding your sever mail file with mail. Simply put MAILTO='' at the top of your crontab and you are set. No more trying to remember the tricky 2>&1 or any other weird hacks.… Read More

Tricks to a Simple and Secure Contact Form using PHP

A day does not go by it seems that someone is asking how to create a simple contact form in PHP. The problem I tend to find is that most of the tutorials online show bad programming practice, such as using the @ error suppressor or not validating / checking the data passed into the form. I decided to write up a few of my tricks on how to do a proper PHP Secure Contact form and attempt to explain why. As always, I welcome comments / suggestions in the remarks. I have decided to omit the Captcha, as I feel Captcha is just broken, so if you want to prevent spam, you will need to research other methods, like Honey Pots.… Read More

Varnish is Running out of Control!

A slug walking across a keyboardMy servers now a days run Varnish simply for the speed. On my main site Varnish was getting out of control with the RAM / Memory usage. Varnish would slowly creep up and eat all the memory, even though I was trying to hack Varnish to only use 128MB of ram, especially since the site is hosted on a lowendbox by Frantech ( The answer, which I am not really sure WHY it works, but inside of vcl_fetch in the /etc/varnish/*.vcl file, I had set beresp.grace to be 30M, I tried this with 2M as well, but ultimately I took out the grace period setting and now my box is running Varnish with Lighttpd and PHP-FPM getting around 15k-30k unique hits a day and not going over 156MB of RAM usage.… Read More

Setting up Mosh (Mobile Shell) Server on Debian Squeeze

A key with a browser behind it.My curiosity takes me to a bunch a different programs that I like to hack around with. Today it took me to setting up a Mosh Server. Mosh is a short term for Mobile Shell, which is attempting to act as an SSH (Secure Shell) replacement for a connection-less state. With Mosh, you are able to roam around on a 3G / 4G / Wifi / Work / Home and not have the need to always reconnect your SSH sessions or have a dedicated server setup with screen, which if that server goes down then you will have to reconnect all the sessions again!… Read More
