WordPress: Installation and Performance

This article describes some of the basics on installing and running WordPress to maximize its performance. The following scripts and text generally assume Debian/Ubuntu, so substitute Red Hat, Arch, etc. as needed.

On my Drupal 7 site here, I wanted to create a method of automatically injecting my Google Ad banners on all content pages before the Disqus comments thread. You could do this manually, say by adding a text field to your basic page content_type with a default value of all the Google Ads JavaScript, but this is clumsy: it clutters up your content pages, and it doesn't retroactively update any existing pages.

Note: This is an old article, and the APC Opcode Cache is now abandoned. Strongly consider installing Zend OPcache instead. APC is now effectively unsupported, although you can still install and use it.
