Installing passenger on existing nginx

The normal installation of passenger usually require you to either do
1. passenger-install-nginx-module, or
2. go to nginx source and reinstall manually with extra –add-module /path-to-passenger-module

I am a bit reluctant to do option-1 because I already have some modules running with my nginx and option-2 is a bit troublesome because I install nginx with apt-get so I dont keep the source code.

Instead I found the official instruction which show me how to upgrade nginx installation in ubuntu.

sudo apt-key adv –keyserver –recv-keys 561F9B9CAC40B2F7
sudo apt-get install apt-transport-https

Create a file /etc/apt/sources.list.d/passenger.list and insert one of the following lines, depending on your distribution.

##### !!!! Only add ONE of these lines, not all of them !!!! #####
# Ubuntu 13.10
deb saucy main
# Ubuntu 12.04
deb precise main
# Ubuntu 10.04
deb lucid main


sudo chown root: /etc/apt/sources.list.d/passenger.list
sudo chmod 600 /etc/apt/sources.list.d/passenger.list
sudo apt-get update
sudo apt-get install nginx-extras passenger

Edit /etc/nginx/nginx.conf and uncomment passenger_root and passenger_ruby.

sudo service nginx restart 

add config file to your site-available

server {
listen 80;
passenger_enabled on;
root /var/www/my_rails_app/public;

if you don’t have nodejs already, install it with this command:

sudo apt-get install nodejs
