Adjusting child processes for PHP-FPM (Nginx)

When setting these options consider the following:

How long is your average request?
What is the maximum number of simultaneous visitors the site(s) get?
How much memory on average does each child process consume?

Determine if the max_children limit has been reached.

sudo grep max_children /var/log/php?.?-fpm.log.1 /var/log/php?.?-fpm.log

Mail Forwarding With Mailgun and CloudFlare

After moving my DNS from Namecheap to CloudFlare I lost the ability to use Namecheap as a mail forwarder. For anyone not sure what that is, essentially it allows you to receive email at anyname@your-domain.com and have it automatically forwarded somewhere else (like your personal Gmail account).

So, what I did is leverage a free account with [Mailgun][1] to setup the same thing.

Mailgun Setup

This is a cron job entry to that will auto renew your Let's Encrypt certificate automatically by running 2 times a day evey 12 hours on a random minute.

You can add a cron job entry by running this command

$ crontab -e

Then past the following snippit in that file, Note that lines 1-3 might not be required at all. Make sure your check the link to the thread regarding this.
