Setup Ubuntu 16.04 Xenial Xerus Discussion

Just ran everything perfectly. Now I just need to learn how to use Rails.

There are so many coding tutorials out there with missing bits, or bits that half-work. Everything here worked first time. Good job!

In case anybody is stuck at rake db:create,

Make sure Inside your databse.yml file, under default: you have the following ( right below pool)

host: localhost
username : your username
password : user's password

When I run "rails server" i see below stuff and doesnt seem to start listening in localhost:3000
Any ideas?

Whenever I use the rails server command or ANY command, I get this - a deprecated warning, what do I do with this? Any way to fix it? And also, how do we uninstall rails if I used rbenv?

username@name:~/Desktop/Web/Rails/myapp$ rails server

i am getting these errors while executing rake command stackoverflow thread said this is the problem with ruby 2.4.0 can may i know how to downgrade my ruby gem

thanks, this was useful!

First of all: Great Guide!
Ive got a little different question going to PageFlow. As this is the best Rails/RoR guide ive found and pretty lost right now i thought i could give it a try here:
I followed every step described here, installed ruby 2.3.1p112 and rails 4.2.7.1
as i try running rails generate pageflow:install i get following error message:
/home/pageflow/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/pageflow-0.11.3/lib/pageflow/global_config_api.rb:17:in `config': Pageflow has not been configured yet (RuntimeError)

since my ruby know how is === 0 maybe one of you ran into the same problem or knows how to solve it? https://uploads.disquscdn.c...

Great article, really helped a lot in installing ruby on rails and starting my first application.

/etc/nginx/sites-enabled/default is not available for me

Hey Chris, this was great for a beginner like me. Though, the only problem I had was with creating a new user for the postgres database as I get "could not change directory to "/home/whoarse": Permission denied". Not sure where to start with this??

Probably the easiest Setup I've came across. Good Job!

I would recommend also installing ruby-dev:
`sudo apt-get install ruby-dev`

This has solved my current installation problem and some that I would have definitely run into.
Thanks Chris.

Tried for two full nights to install rails on Ubuntu, this is the first site to explain step by step, so a HUGE Thank You! I'm now on my way up the learning curve.

Why this way and not taking the packages from repositories? Is it due old versions and incompatibilities?

Icing on the cake:
echo 'gem: --no-rdoc --no-ri' >> ~/.gemrc
gem install pry && echo 'alias irb=pry' >> ~/.bashrc
