Transition to Production

Secret Key

Not needed for development, but needed for production.

• run rake secret to create a giant random number
• add this line to /etc/default/nginx:

export SECRET_KEY_BASE=bcd25705f5c39e...

• run "chmod 600 /etc/default/nginx" to keep the secret secret.

Compile Assets

You will need to manually compile your assets before going into production:

rake assets:precompile

Install Nginx with Passenger

Since we’ll be using Nginx for serving our application, we’re going to install it using the Passenger installer. Nginx modules need to be compiled into nginx, unlike Apache, so we can’t just install the package from the PPA.

sudo gem install passenger
sudo passenger-install-nginx-module
# Choose "download, compile, and install Nginx for me"
# Accept defaults for any other questions it asks you

Upgrading Nginx

sudo gem update passenger
sudo passenger-install-nginx-module
# go ahead and install latest nginx with ruby support

This will overwrite existing files in place. Then you will need to update the "passenger_root" directive in nginx.conf to point to the latest passenger gem.

Confirm server version with this:

/opt/nginx/sbin/nginx -v
