Did I Mention That They're Rough?

Ubuntu 12.04, Ruby, Rails, Nginx, Unicorn and git-deploy

In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.

Server Setup

Create new server
Login to new server
- ssh root@IPaddress (you can also use the domain name if you have the DNS setup already)
- accept the RSA key

This list has been superseded by Public APIs. Check there for APIs with Auth: No, HTTPS and CORS Yes.

List of data APIs that require no server-side auth or private credentials, and are thus good for small browser-only JS projects.

Updated for Rails 4.0.0+

Bower

Set up the bower gem.
Follow the Bower instructions and list your dependencies in your bower.json, e.g.
```
// bower.json
```

Frontend Development

In Rails 3

If you add a dir directly under app/

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

If you add a dir under app/something/

Port Forwarding in Mavericks

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

####1. anchor file Create an anchor file under /etc/pf.anchors/<anchor file> with your redirection rule like:

	gifify() {
	if [[ -n "$1" ]]; then
	if [[ $2 == '--good' ]]; then
	ffmpeg -i $1 -r 10 -vcodec png out-static-%05d.png
	time convert -verbose +dither -layers Optimize -resize 600x600\> out-static*.png GIF:- \| gifsicle --colors 128 --delay=5 --loop --optimize=3 --multifile - > $1.gif
	rm out-static*.png
	else
	ffmpeg -i $1 -s 600x400 -pix_fmt rgb24 -r 10 -f gif - \| gifsicle --optimize=3 --delay=3 > $1.gif
	fi
	else

	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
