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).

  "^/(.*).(.+)$" => "$0",
  "^/(.+)/?$" => "/index.php/$1"

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.

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

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 (Buyvm.net). 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
