Moving from Apache to Nginx Web Server for better WordPress performance

Moving a WordPress site from Apache to Nginx isn’t easy, but is well worth the effort – if you are on a micro instance and memory is at a premium.

kermit_memeI’ve written multiple posts about optimizing my blog to increase speed (here, here, and here)… unfortunately, my web server continues to crash at least once a day (usually due to a spike in traffic).

I started looking to stripping out unnecessary Apache modules, but had too many problems identifying the required modules for WordPress. After 30 minutes of failed server re-starts, I decided to ditch Apache all together and install Nginx as my webserver.

While Apache is the most well know WordPress webserver, Nginx is growing in popularity ( uses Nginx on their site). In order to get a clean install, I created a new t2.micro instance, installed Nginx (and php-fpm) and migrated my WordPress files over 1.

There isn’t a lot of documentation on Nginx: I spent most of my time referencing the instructions at the following sites:

The install wasn’t smooth sailing. I had a beast-of-a-time getting my permalinks to work, and I forgot to change a few of my settings in my wordpress.php conf file (which caused my server to constantly crash).

There are still a few things I need to reconfigure – W3 Total Cache works differently in Nginx, so I’ve ignored it. I also have yet to re-install my certificates for https.

All that being said, my website is as fast as it was when I started my blog – probably due to Nginx, as well as the lack of “bloat” on the server (old WordPress plugins and no MySQL install).

My other call-out is that the use of AWS RDS and an Elastic IP made the most complicated parts of the migration simple.
