Stop xmlrpc.php Attacks

Summary: how to diagnose and eliminate the xmlrpc.php WordPress exploit when it's clobbering your web server.

You've been running a public Ubuntu 12+ and Apache/LAMP web server for a while now. Until recently everything has worked fine, but suddenly your server is struggling to display even static pages.

Install the Latest Nginx From Source on Ubuntu 16.04

So you want to install Nginx from source on Ubuntu. However, you want Nginx to work like you had installed it with the package manager. This means the startup file (/etc/init.d/nginx), binary (/usr/sbin/nginx), config directory (/etc/nginx/) and log files (/var/log/nginx/) will all be found in the usual Debian/Ubuntu locations. Fortunately this is pretty easy to do using the Debian dpkg utility and Nginx repos.

Ubuntu 16.04 Web Server with Nginx, MariaDB, Redis, and Drupal 8

As mentioned in my Ubuntu 16.04 and Drupal 7 article, the Ubuntu 16 LTS version has some nice upgrades, including PHP 7, MySQL 5.7, Nginx 1.10, Apache 2.4.18, and MariaDB 10.0.x. Let's see if we can make it work with Nginx, PHP-FPM, MariaDB, and Drupal 8, using the Redis key-value store as the backend cache instead of Drupal's cache tables. The procedure is largely the same as before, with a few differences for the new Drupal version.
