Recovery from nginx "Too many open files" error on Amazon AWS Linux

On Tue Oct 27, 2015, history.state.gov began buckling under load, intermittently issuing 500 errors. Nginx's error log was sprinkled with the following errors:

2015/10/27 21:48:36 [crit] 2475#0: accept4() failed (24: Too many open files)

2015/10/27 21:48:36 [alert] 2475#0: *7163915 socket() failed (24: Too many open files) while connecting to upstream...

An article at http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/ provided directions that mostly worked. Below are the steps we followed. The steps that diverged from the article's directions are marked with an *.

  1. * Instead of using su to run ulimit on the nginx account, use ps aux | grep nginx to locate nginx's process IDs. Then query each process's file handle limits using cat /proc/pid/limits (where pid is the process id retrieved from ps). (Note: sudo may be necessary on your system for the cat command here, depending on your system.)
  2. Added fs.file-max = 70000 to /etc/sysctl.conf

Setting up a WordPress site on AWS

Setting up a WordPress site on AWS

This tutorial walks through setting up AWS infrastructure for WordPress, starting at creating an AWS account. We'll manually provision a single EC2 instance (i.e an AWS virtual machine) to run WordPress using Nginx, PHP-FPM, and MySQL.

This tutorial assumes you're relatively comfortable on the command line and editing system configuration files. It is intended for folks who want a high-level of control and understanding of their infrastructure. It will take about half an hour if you don't Google away at some point.

If you experience any difficulties or have any feedback, leave a comment. 🐬

Coming soon: I'll write another tutorial on a high availability setup for WordPress on AWS, including load-balancing multiple application servers in an auto-scaling group and utilizing RDS.
