Install RVM, Passenger, Nginx and Rails 3 on Ubuntu Lucid Lynx
This has been a problem encountered by several developers including myself:
Getting RVM, Passenger and Rails3 to work
Here's a quick and short post. Supposing you already have updated Ubuntu and have Ruby installed. These are the only commands you should need:
rvm install 1.9.2
rvm 1.9.2 --passenger
rvm 1.9.2
gem install passenger
rvmsudo passenger-install-nginx-module
#use rvm by default
rvm 1.9.2-preview3 --default
#edit the nginx config file. mine is on /opt/nginx/conf/nginx.conf. just change username
passenger_root /home/username/.rvm/gems/ruby-1.9.2-preview3/gems/passenger-2.2.15;
passenger_ruby /home/username/.rvm/bin/passenger_ruby;
#reboot if you can. I recommend rebooting over restarting/stopping and starting nginx server. reboot was actually the fix I needed after following all the steps above.
sudo reboot
#.rvmrc file on your Rails 3 app should contain. this may be optional but in case you've set a different ruby version, this helps.
if [[ -s "~/.rvm/environments/ruby-1.9.2-preview3" ]] ; then
. "~/.rvm/environments/ruby-1.9.2-preview3"
else
rvm --create use "ruby-1.9.2-preview3"
If nothing works for you. Check your path, your ruby version and check whether bundler is installed.
How to installed bundler for Rails 3:
gem install bundler --pre
Most gems for Rails 3 require "--pre" by the way.
Installing gems
cd app/dir && bundle install
It's that simple. But something failed. I use mysql and pg gem. I use mysql gem for test and development environment because they work better for testing. But I use postgresql for production and staging. Mysql gem was not installed by bundler. You have to run this:
gem install mysql -- --with-mysql-config=/usr/bin/mysql_config
Hope this helped someone.
