Rails 3.2.7 SSL Localhost (no red warnings, no apache config)

gistfile1.sh

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

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

$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key


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

$ openssl req -new -key server.key -out server.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 server.csr -signkey server.key -out server.crt

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

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

# 6) Boot thin

$ thin start --ssl --ssl-verify --ssl-key-file server.key --ssl-cert-file server.crt

# 7) Add server.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.
#

rceee, I got the same issue. I suspect it has to do with permissions, but I was not able to fix it with chown unfortunately (could just be my incompetence).

Cool, it was finally the only detailed solution on the web that worked for me.

Ain't there a way to add the thin start --ssl --ssl-verify --ssl-key-file server.key --ssl-cert-file server.crt somewhere in the development.rb file to being able to keep using rails server as a start command?

Thanks

it appears --ssl-verify option can be removed (it is the default) in later versions of thin (~ 1.6)

If you have problems directly importing the certificate into your system keychain, you might have to add it to the login keychain and trust it first, then unlock your system keychain and paste it there.

@trcarden and @igalic, thanks!

thin start --ssl -p 3001 worked for me!

Can you explain more about "echo "127.0.0.1 localhost.ssl" | sudo tee -a /private/etc/hosts" ?

Hi @wangbourne, it's a way to pipe output into a file that requires sudo privileges. You can't pipe output of a sudo'd command with >. It's basically appending the echo command to the end of the file /private/etc/hosts.

This worked for me (Rails 4.2)

$ thin start --ssl
