Ruby script to convert Rails Latin1 / latin1_swedish_ci database tables to UTF8 / utf8_unicode_ci. See: http://stackoverflow.com/questions/9479607/rails-show-question-marks-for-my-input-utf8-data http://stackoverflow.com/questions/13999026/utf-8-data-in-latin1-database-can-it-be-saved
tables = [] # or ActiveRecord::Base.connection.tables
collation = "utf8_unicode_ci"
char_set = "utf8"
db = "your_database_name"
# write out
puts "USE #{db};"
puts "ALTER DATABASE #{db} CHARACTER SET #{char_set} COLLATE #{collation};"
tables.each do |t|
puts "ALTER TABLE #{t} CHARACTER SET #{char_set} COLLATE #{collation};" # changes for new records
puts "ALTER TABLE #{t} CONVERT TO CHARACTER SET #{char_set} COLLATE #{collation};" # migrates old records

Let's Encrypt on Ubuntu 14.04, nginx with webroot auth

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.

As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:
