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

CentOS 7 Kickstart File & How to build an (auto install) ISO

CentOS 7 Kickstart File - HOWTO Build ISO

There is so much documentation online from RedHat and CentOS about this topic - it's sad that I am writing this. But the real state of documentation on this topic (CentOS 7 + KS + ISO = Bootable DVD) is almost non-existent.

I found this: http://smorgasbork.com/component/content/article/35-linux/151-building-a-custom-centos-7-kickstart-disc-part-1

Which I greatly appreciate and +1, but the documentation is half-baked and there are numerous errors.

Finally... FINALLY! After four days of banging my head, I got this to work. Hopefully someone else will be able to do this in a few hours, instead of blowing their weekend like me. :(
