Setup Ubuntu 14.04 Trusty Tahr Discussion
I am new so please don't be harsh. I want to learn Ruby on Rails and I was told that I should install it on Ubuntu so I downloaded Ubunto 14.04 LTS (the desktop version). That is great! Now I wanted to install Ruby on Rails. I did a search and found your website. I am afraid I am lost at: The first step is to install some dependencies for Ruby. Where do I enter command lines? I can't even find help on Ubunto LOL. I am a Windows vet and trying to convert but for now I am lost for a monent and would appreciate your help. Thanks so much.
No worries! There is a application called Terminal that you want to type these commands in. Open up that and type them in there and you should be fine.
Thank you. The terminal app worked perfectly. Just a note that with Ubuntu 14.04 I was getting an error message stating they could not verify the authenticity of the host github.com after creating my key but gave me the option to add it permanently. When I ran the command line to verify my key I got the message
Warning: Permanently added the RSA host key for IP address '192.30.252.130' to the list of known hosts.
Hi Msjay2u! You've successfully authenticated, but GitHub does not provide shell access.
The next time I ran it to verify I just got the success message without the warning line.
Seems there is a problem with their DNSSEC (Domain Name System Security Extensions)
That error/warning is just to make sure you know you're connecting to a computer that you've never talked to before. Glad everything is working well!
Instead of
sudo sh -c "echo 'deb http://apt.postgresql.org/p... precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
use
sudo add-apt-repository 'deb http://apt.postgresql.org/p... precise-pgdg main'
Much cleaner, thanks!
Great article thanks! I seem to be unable to install other versions of Ruby. For example, if I cd into a directory and try to install Ruby 2.0.0-p247 I get an error on compile. Is this due to the deadline issues going around? Anyone know how to fix this? I tried to install using the patch as noted above, but that did't work either.
You can run the following command if you'd like to install Ruby 2.0.0-p451 instead of 2.1.1:
curl -fsSL https://gist.github.com/LeonB/10503374/raw | rbenv install --patch 2.0.0-p451
It requires a different patch than 2.1.1 does.
why not use PostgreSQL 9.3 from the Trusty Thar repo?
You're right, I'll switch it over to the Trusty repo. Eventually when PostgreSQL's official repo is available for trusty I'll switch it back because you're always guaranteed to get the latest version on their repo. The Ubuntu repositories tend to lag behind the official releases so I lean towards using the postgres provided ones if I can.
Installing from source can cause frustration down the road when you need to work on a project written with a different ruby version. Usually the changes needed to get it working on a different ruby version are minimal, but working with other people who have conflicting ruby versions becomes difficult if you're back- or forward-porting code. But on a production environment, or a box that will only be used for personal ruby projects, it's sometimes nice to know that your ruby is installed in the simplest way possible - directly in the path.
How about adding a few steps to setup an app server like unicorn passenger or puma? That would be great
Good idea, but those are more for production environments. The Deploy Rails tutorial is more geared for setting up a server and covers Nginx + Passenger. This tutorial is for your development environment.
Please mention common compile fail because of "readline error" and this patch that fixes it https://github.com/sstephen...
This is fixed now in the latest versions of 2.1 and 2.0 that were released yesterday!
HI i got this error while installing ruby with rvm on 14.04
Partial file(18). Only a part of the file was transferred. Removing partial and re-trying.
rvm installed successfully.
rvm requirements is passed
Sounds like the download got interrupted. You probably should delete the file they mention (assuming they tell you which one didn't finish) and try again.
Thanks! Went well. One suggestion, SQLite!
You should have sqlite3 installed if you followed all the steps. And to generate a Rails app with Sqlite, just skip the -d option and use rails new myapp
I'll add a comment to the last part to make that more clear. Thanks!
Hi for `add-apt-repository` command I think what you need is "software-properties-common" package instead of the python stuff, see: https://askubuntu.com/quest...
Hi Chris,
Great article. I was able to follow the steps untill MySQL installation, after that I created an app,
$rails new myapp -d mysql
And was shown the following error,

Please help me out. I did a "bundle install" but it just said "Unknown Host name"
Sounds like you had internet connectivity problems. Try running it again and see if it works next time?
I did the setup but how do I start building application, I am new to ruby on rails
Hello,
I am new to Rails: How can update my config/database.yml file to match the database username and password.
You can just open that file in your favorite text editor and set the username and password keys inside it. I'd recommend using Sublime Text or something similar to do that.
Great tutor :D
Can I prepare my RoR project in offline mode? without internet connection.
Thanks
If you've already downloaded all the gems and ruby versions, you can work offline but if you need to install anything new, you'll need an internet connection.
this version of ruby has been hunting me, 1.9.3p484: first i had rbenv but i did alot of stuff with that included installing 2.1.2 and i put ruby -v and 1.9.3 pops up, i dealt with that all day yesterday and alot today, just 30 mins ago i unstalled rbenv and install rvm and install 2.1.2 and still 1.9.3p484 pops up, i would really be thankful for any advice you could give me on this
If you have multiple versions of ruby, you'll want to set the default (or use rbenv/rvm to switch). For me, I have 1.8.7, 1.9.3, 2.0, and 2.1 installed on my machine. I set 2.1.2 as the default, but certain applications switch back to 1.9 and 1.8.7 for me.
I'd guess you just haven't set the default to 2.1.2 yet and that's what is missing.
when i try [ rvm --default use 2.1.1 ] this happens RVM is not a function, selecting rubies with 'rvm use ..' will not work.
Take a look at this: http://stackoverflow.com/qu...
i couldn't install it. can someone help me out?
shaun@ubuntu:~$ rvm install ruby-2.1.2
Searching for binary rubies, this might take some time.
No binary rubies available for: ubuntu/14.04/x86_64/ruby-2.1.2.

Does sudo apt-get update
work? It's saying something is wrong with that.
You see this because of your apt-get update fail to update some packages. If there is any failure in your apt-get update the install rvm is not working. So you have to fix all the failures in apt-get update command.
Solution :-
remove 3rd party packages give 404 error in update.
sudo add-apt-repository --remove <package-name>
do this there is not error in apt-get update.
then install the rvm
I think this will help to solve the problem.
At some point an article on installing and using nginx and passenger would be great:-)
Check out https://gorails.com/deploy/... ;-)
Chris, get setup ...it worked well..... but maybe i placed myapp in the wrong location. Its in /home/ubuntu/myapp. I cannot ping 127.0.0.1:3000 and cannot access the Ubuntu AMI externally. Rails server ran successfully on port 3000. Thanks for any ideas.
Hey Steve, this setup is primarily for development. On a production AMI on AWS you probably want to run a server like Passenger so that it can serve up the app on port 80. This tutorial might be more what you're looking for https://gorails.com/deploy/...
If you're wanting to do development on AWS though, you probably just need to open up port 3000 in your security group because I can bet the firewall is blocking it.
Why on sites which are pleasant to me there are no social buttons with "like buttons"? Good guide, thanks.
Thanks Chris, this is just what I was looking for to get my development server up and running.
Thanks for the tutorial, it all worked, got only one problem. I need to have root privileges to create new app (or even check rails version). When I try creating new app as normal user I get error:
The program 'rails' can be found in the following packages:
* ruby-railties-3.2
* ruby-railties-4.0
Is there way to change that, so I wouldn't have to be constantly logged in as root while working on my projects?
If you used rbenv, make sure you run rbenv rehash
after installing the Rails gem. That makes the gem's executables available to use. It currently isn't available, so Ubuntu is suggesting a different installation method.

Very helpful. I did get hung up at one point with a failed ruby build in rbenv, apparently related to readline bug. This was fixed by running a patch per https://github.com/sstephen... where I substituted my ruby version for the one listed.
Thanks John. That *should* be fixed in Ruby 2.1.2. Is that what you were installing?
Thank you for a wonderful tutorial! Too many of the instructions you find about rails nowadays are from several years ago and aren't the best practices.
I am try to execute this comand
cat ~/.ssh/id_rsa.pub and got the following
grim@Reaper:~/.ssh$ cat ~/.ssh/id_rsa.pub
cat: /home/grim/.ssh/id_rsa.pub: No such file or directory
Then I switched it to the RSA key I made and got the same thing
grim@Reaper:~$ cat ~/.ssh/gitRSAkey.pub
cat: /home/grim/.ssh/gitRSAkey.pub: No such file or directory
Thanks for the great step-by-step. It's been a long time since I used unix/linux, and the world has become much more complex. I instzalled on a new, clean Ubuntu 14.04 and had no problems at all.
I am running ubuntu 12.04 LTS. Will these procedures work on it as well??
The package names have probably changed a bit. You may want to switch to the 13.04 version as it probably has some more similar package versions.
Thanks for the great writeup! I have put this entire process into a shell script to run during vagrant provisioning, and here were a couple of gotchas related to the rbenv install, for those taking this path. This was using the "ubuntu/trusty64” vagrant box (Ubuntu 14.04).
1) In your Vagrantfile, in the config.vm.provision line that calls the script, add the "privileged: false" option at the end, so that it runs as the vagrant user, not sudo. Otherwise the PATH updates (e.g. rbenv) will go into the wrong .bashrc file and the script won't be able to find rbenv later. (Or I guess you could specify that the PATH updates go to /home/vagrant/.bashrc).
2) The "exec $SHELL" commands will cause the script to terminate. I tried a number of solutions to get the PATH updates to take effect, as described in this StackOverflow thread (http://stackoverflow.com/qu..., but eventually the only solution that worked for me was to comment those out and use the full path to rbenv and gem.
Thus I replaced these lines:
rbenv install 2.1.2
rbenv global 2.1.2
gem install rails -v "=4.1.5"
rbenv rehash
With these:
~/.rbenv/bin/rbenv install 2.1.2
~/.rbenv/bin/rbenv global 2.1.2
~/.rbenv/shims/gem install rails -v "=4.1.5"
~/.rbenv/bin/rbenv rehash
"You want to copy and paste the output of the following command and paste it here.
cat ~/.ssh/id_rsa.pub"
cat: /home/usr/.ssh/id_rsa.pub: No such file or directory
Got it. Now to figure out the extent of my pebkac.
Well thanks a lot .... installed beautifully .......... for a beginner in ruby on rails ... took me a while to figure this out ...........
I had problems with add-apt-repository. Seems like the dependency might need to be software-properties-common (not sure)
excellent excellent: one of the best written instructions set i have ever ever seen on the interent. and i've been to a lot of forums and read a lot of things, esp coming as a ubuntu user learning this thing: but where or where dear friend is the config/database.yml file located? it's really the only thing that is missing........999.999/1000 almost perfect almost full marks
ok i have found it. the config/database.yml file is located at ~/myapp/config/database.yml (of course the tilde "~" denotes the home directory) it's easy once you know but if u dont' know it is a big headache!
Ah yep! Pretty much anytime someone (like myself) mentions a file without giving a full path, they mean inside your Rails app's directory like that.
I followed the guide and got n error at "ssh -T git@github.com". Before this step you need to makean "ssh-add" to add the generated key
So... this all worked great... until I opened a new terminal and it didn't know where to find rails until I manually typed exec $SHELL in there again. How to make this automatically work?
That's what will happen if you missed the echo lines to write that code into your ~/.bashrc file. Without those lines, it won't load your ruby environment so they're important!
Chris, great information, i was able to install smoothly. i am on amazon AWS ubuntu instance, after creating the app, from my desktop browser, testing localhost:3000 did not work, i tried using ip address of the server and also dns name, http, https, no luck, any idea, how i can test this? Thanks for great instructions
If you set this up remotely, you need to manually run the rails server in an SSH connection and then visit the server IP with the port of 3000. So http://SERVER_IP:3000
A better thing to follow for AWS is the deploy tutorial where your Rails apps are hosted on something remote like AWS or Digital Ocean. It uses Nginx & Passenger so that your Rails apps are always running.
Very good article.
On my laptop with Ubuntu I've just used:
rvm install 2.1.3
rvm use 2.1.3 --default
ruby -v
And all it's OK . Thank you so much !
The guide recommends 2.1.3, but the instructions install 2.1.2 ;)
Fixing. :)
Latest release of RVM will throw an error stating signature verification failed. Execute this line: gpg --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3 before downloading RVM.
you can use this tutorial to come out from that error you may want to use ruby version control ....... see here how to install RVM http://buffercode.in/instal...
Should we use the NodeSource distributions repo for nodejs instead of Chris Lea's repo? https://github.com/nodesour...
Good question. I'm not sure about NodeSource, but I'd say as long as Chris Lea keeps updating his repo (and he seems to quite consistently), you're fine with that. Feel free to try out NodeSource and let me know how it goes.
I follow the instuction and using rvm
everything was fine, but when I install rails, I got this error.
ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError)

any ideas why? and how to fix it?
sudo apt-get install libffi-dev is also needed on ubuntu 14 for ruby 2.2.1
https://github.com/sstephen...
Thanks! I've added that to the instructions. :)
When running rbenv install 2.2.1
, I get rbenv: no such command `install'
.
Anyway, why in the world is it so complicated to just install the latest Ruby?
Make sure you run the ruby-build lines before that.
You could skip all this and use apt-get to install Ruby, but the reason we do this is so that when a new version comes out later, you can easily upgrade without losing anything. apt-get will stick you with one version and you won't be able to upgrade it until the Ubuntu developers get around to adding the new version which takes quite some time.
Why is there no simpler way to set Ruby i[? Why are the packages in Ubuntu no longer maintained properly? It's kind of idiotic. To be honest, it makes it harder to automate deployment on multiple machines. You can't provision like this...
Well, the issue isn't that the packages aren't maintained properly. It's that the software doesn't get upgraded to be compatible with the latest Ruby releases always. Sometimes you have code that works on specific versions of Ruby and that means you will need to install that version specifically on your server. That's why everyone recommends using a Ruby version manager of some kind like rbenv to handle this. Once you get the hang of it, it goes smoothly, but at first it can be daunting and a bit of a pain to set up.
I completed all installation successfully but am unable to access my localhost using port 3000 through my web browser. Would appreciate your help. Thanks.
No need to install ruby-dev environment or what? Isn't that necessary?
Nope, This should be all you need.
Hello, im on elementary os freya, i did this steps:
cd
git clone git://github.com/sstephenso... .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone git://github.com/sstephenso... ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
git clone https://github.com/sstephen... ~/.rbenv/plugins/rbenv-gem-rehash
but when i try to do:
rbenv install 2.2.2
i get this message:
The program 'rbenv' is currently not installed. You can install it by typing:
apt-get install rbenv
any idea?
You might need to restart your terminal. Sometimes the PATH doesn't get set correctly so restarting the terminal helps or re-running these commands (namely the "echo" lines).
how to repair this error; i want eliminate this configuration and I want to clear all settings and leave as if nothing had happened
bash: /home/nitroherman/.bashrc: línea 168: error sintáctico cerca del elemento inesperado `PATH="$HOME/.rbenv/bin:$PATH"'
bash: /home/nitroherman/.bashrc: línea 168: `esacexport PATH="$HOME/.rbenv/bin:$PATH"'
You can just remove that line from the bashrc file. I believe it should be
export PATH="$HOME/.rbenv/bin:$PATH"
Great tutorial! Thanks for putting the time and effort into creating it for us new to the wonderful world of Ruby on rails.
Hi! Can you help me?!

I'm entering: cat ~/.ssh/id_rsa.pub

what am I doing wrong???
I watched the installation progress to see what URLs were used for download. I noticed Ruby was being downloaded from cloudfront.net:
http://dqw8nmjcqpjn7.cloudf... . I pasted the URL in VirusTotal and all came back clean except the AutoShun scan which said it was a malicious site. I'm assuming this is a false positive?
Anyone else have any comments or concerns about this?
ClamAV scan of the filesystem came back clean afterwards.
Thanks for the detailed, seamless instructions!
That should be good. Cloudfront is a CDN so it caches files so you can download them faster around the world. It's something you have to configure so Ruby's website is probably forwarding you to that. Good to verify that it's not malicious in any case!
I'm having trouble at the git install section, after these steps:
git config --global color.ui true
git config --global user.name "YOUR NAME"
git config --global user.email "YOUR@EMAIL.com"
ssh-keygen -t rsa -C "YOUR@EMAIL.com"
After the four consecutive steps I am asked where to save my file. When I enter a destination folder it fails. Am I supposed to create a file for it to be saved in? If so, how etc? Thanks in advance.
You want to save it to the default location by just hitting ENTER. What's the failure say?
Awesome tutorial.
You're missing '~' in the Installing Ruby section, after the 'cd', in the 'Using rbenv' code snippet.
Fun fact! You don't need ~ because it will default to that if you don't put it in. I learned that not too long ago. :)
--no-ri and --no-rdoc are deprecated. You might want to update it to --no-document.
Yes indeed! I noticed that recently. Thanks for the reminder!
For postgresql you need to make sure the user your create matches the username you are logged in as. If not you'll run into errors that "Peer authentication failed for user..."
Thanks heaps. Solved my problem.
Hey Guys! Nice post, I have some problems when I tried to run rake db:schema:load, due to some postgres missing plugins, to solve that I had to install postgres-contrib
so, it's better use
sudo apt-get install postgresql postgresql-contrib libpq-dev
instead of
sudo apt-get install postgresql libpq-dev
;)
Using Ubuntu 14.04 (Trusty) and RVM I needed install ruby with
rvm install 2.2.3 --disable-binary #or if you already did install: rvm reinstall 2.2.3 --disable-binary
in order to have the development headers available for nokogiri et al.
Thanks for the guide!
Hi @joshuarumbut:disqus , thanks for this comment! helped a lot.
as of Sep/6/2015 this guide is still on point. great job and thank you for this :)
I keep it updated as much as I can! :)
Guide that finally that let me install rails without visiting stackoverflow again :)
That's my goal!
Sounds like you don't have an SSH key on your machine. You might need to generate a new one or install an old one if you have one you created previously.
while try to enter
ssh -T git@github.com
it shows me Permission denied (publickey).
Hi Prasanna,
When you put the follow command:
git config --global color.ui true
git config --global user.name "YOUR NAME"
git config --global user.email "YOUR@EMAIL.com"
ssh-keygen -t rsa -C "YOUR@EMAIL.com"
You should put your own email.
After that, you need to create new account on www.github.com, next, you need to create a new ssh key, and, after that, you can put the 'ssh -T "YOUR@EMAIL.com"' command. But, you should put YOUR OWN EMAIL, not "git@github.com" email
Try, and you'll see it works
Greets!
Hello am facing an issue in gems installation. PS. already tried sudo apt-get install build-essential

use
gem 'mysql2', '~> 0.3.18' in gem file
Great job! I appreciate your help! TY so much! But, i have one information that can be necessary and important to someone.
The version of my ubuntu is 14.04, and the current version of the mysql2 is installed with the last version (stable) ruby.
If
you have a problem similar as: " Gem::LoadError Specified 'mysql2' for
database adapter, but the gem is not loaded. Add `gem 'mysql2'` to your
Gemfile", and your server not work, the solution can be a following:
Open
your folder that contain your project, and find your Gemfile. In the
gemfile, add the version of the mysql2 '~> 0.3.20' . For example:
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.4'
# Use mysql as the database for Active Records
gem 'mysql2', '~> 0.3.20'
After these steps, you can be continue your setup normally.
Regards!
Diego Cassol.

Hi there. I encountered some problems when setting up ruby on rails using this tutorial, if you have time please take a look at my question on stackoverflow:

Hi, I am new on ruby, and i tried to install ruby as mentioned in this article (I am using linux mint 17.2, I think it would be the same with ubuntu 14.04 right?) and I got this error :
Downloading ruby-2.2.3.tar.gz...
-> https://cache.ruby-lang.org...
error: failed to download ruby-2.2.3.tar.gz
also I've tried for the other version, but end up with the same error. I think the issue is not the network because I tried manually download the file and it was works. What should I do ?
Thank you.

While installing ruby using rbenv i got
compilation error it says
Ssl_v3 undefined something like it.
Even though i have installed libssl-dev too.
I'm trying to install ruby 2.2.3 in my ubuntu. I'm running this ubuntu from a bootable Disk with persistence.
I followed the guide above until rbenv install 2.2.3, then I received a installation failed message. the message is as shown below:
-------------------------------------------------------------------------------------------------------------------------------------------

Can anyone please teach me what is wrong and how I can solve it?
Thank you very much.
For those who having problem with ruby gem, please do this:
gem update
gem clean
Some old gems wont uninstall itself. This would solve gem problem.
I greatly appreciate this guide. I'm getting into Linux and Ruby on Rails after 17 years of developing in MS technologies. It's a Renaissance. There are several good "getting started" guides, and this is only my fifth so far, but it is the best.
Thanks for much for that Zachary! :)
Neither "quick" method works in a standard 14.04 64 Bit.
Following the instructions the
rnenv method will run forever and never finish. ever.
rvm method fails with error 100.
Build from source I got to work.
Thanks man. Every time I do a clean install of Rails I'm like, "Now what was that page called that worked every time and actually made sense?" :)
That means a lot! Thanks so much for saying that Gilbert! :D
A friendly reminder that there is an official Ubuntu package for RVM: https://github.com/rvm/ubun...
Had a long issue with the Git SSh key file name. Would recommend explaining where to leave blank (and maybe add a link to the awesome Github guide).
This guide was great, and in fact I used it to install on windows 10 with the new WSL bash window (at least to where I have rails running)... Just for people's info here are the changes and additions to get things to work nicely.
1) after installing bundler make sure to do a "find ~/.bundle/cache -type d -exec chmod 0755 {} +" due to a sort-of issue with latest bundler.
2) then if using rails 5 make sure to use the --skip-spring --skip-listen options and make sure that this line in development.rb is commented out (it should be)
#config.file_watcher = ActiveSupport::EventedFileUpdateChecker
Number #2 is because inotify is not implemented (yet) in windows WSL.
when i search 'install rvm on ubuntu' google give this site at 3rd position, it should be first
I couldn't agree more. :)
Good for new versions of ruby and rails but not working on Old ruby and rails versions.
