SSL on localhost, reusuable across multiple Rails apps

gistfile1.sh

# SSL self signed localhost for rails start to finish, no red warnings. 

# 0) Unless present, create `~/.ssl/`

$ mkdir ~/.ssl

# 1) Create your private key (any password will do, we remove it below)

$ openssl genrsa -des3 -out ~/.ssl/localhost.orig.key 2048

# 2) Remove the password

$ openssl rsa -in ~/.ssl/localhost.orig.key -out ~/.ssl/localhost.key


# 3) Generate the csr (Certificate signing request) (Details are important!)

$ openssl req -new -key ~/.ssl/localhost.key -out ~/.ssl/localhost.csr

# IMPORTANT
# MUST have localhost.ssl as the common name to keep browsers happy 
# (has to do with non internal domain names ... which sadly can be
# avoided with a domain name with a "." in the middle of it somewhere)

Country Name (2 letter code) [AU]:
...
Common Name: localhost.ssl 
...


# 4) Generate self signed ssl certificate 

$ openssl x509 -req -days 365 -in ~/.ssl/localhost.csr -signkey ~/.ssl/localhost.key -out ~/.ssl/localhost.crt

# 5) Finally Add localhost.ssl to your hosts file

$ echo "127.0.0.1 localhost.ssl" | sudo tee -a /etc/hosts

# 6) Boot thin

# thin < 1.6.2
$ bundle exec thin start --ssl --ssl-verify --ssl-key-file ~/.ssl/localhost.key --ssl-cert-file ~/.ssl/localhost.crt

# thin >= 1.6.2
$ bundle exec thin start --ssl --ssl-key-file ~/.ssl/localhost.key --ssl-cert-file ~/.ssl/localhost.crt

# 7) Add localhost.crt as trusted !!SYSTEM!! (not login) cert in the mac osx keychain
# Open keychain tool, drag .crt file to system, and trust everything.

# Notes:
# 1) Https traffic and http traffic can't be served from the same thin process. If you want 
#    both you need to start two instances on different ports.
