Ruby On Rails Installation on Ubuntu 14.04

Source: Installing Ruby on Rails on Ubuntu 14.04 – 15.10 and Install Ruby on Rails · Ubuntu Linux.

Installation:

1. Install Ruby Version Manager (RVM). I already had ‘curl’, so import the rvm.io public key in the server system.
   
   teddy@teddy-K43SJ:~$ curl -#LO https://rvm.io/mpapis.asc ######################################################################## 100,0%

   1 2	teddy@teddy-K43SJ:~$ curl -#LO https://rvm.io/mpapis.asc ######################################################################## 100,0%

   
   
   teddy@teddy-K43SJ:~$ gpg --import mpapis.asc gpg: key D39DC0E3: public key "Michal Papis (RVM signing) <mpapis@gmail.com>" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)

   teddy@teddy-K43SJ:~$ gpg --import mpapis.asc gpg: key D39DC0E3: public key "Michal Papis (RVM signing) <mpapis@gmail.com>" imported gpg: Total number processed: 1 gpg:               imported: 1  (RSA: 1)

   
    
2. Then download the RVM installer with curl and execute it (by piping the curl output to bash):

   KEEP IN MIND THIS LINE
   
   To start using RVM you need to run `source /home/teddy/.rvm/scripts/rvm

   1	To start using RVM you need to run `source /home/teddy/.rvm/scripts/rvm

   
   I need to execute ‘source /home/teddy/.rvm/scripts/rvm’ to build the RVM environment and to save the settings of this environment into current shell.
   
   teddy@teddy-K43SJ:~$ source /home/teddy/.rvm/scripts/rvm

   1	teddy@teddy-K43SJ:~$ source /home/teddy/.rvm/scripts/rvm

   
   NOT (ref: Error message: -bash: /etc/profile.d/rvm.sh: No such file or directory)
   
   teddy@teddy-K43SJ:~$ source /etc/profile.d/rvm.sh bash: /etc/profile.d/rvm.sh: No such file or directory

   1 2	teddy@teddy-K43SJ:~$ source /etc/profile.d/rvm.sh bash: /etc/profile.d/rvm.sh: No such file or directory

   
    
3. Install the Ruby dependencies with the RVM command below:
   
   teddy@teddy-K43SJ:~$ rvm requirements

   1	teddy@teddy-K43SJ:~$ rvm requirements

   
   For the first time, I got some errors like this:

   SOLUTION: ref: Error installing Ruby on Ubuntu 14.04
   I have to fix/remove some failed ubuntu repository. From ‘sudo apt-get update’, I got these repositories error:
   
   W: GPG error: https://apt.dockerproject.org ubuntu-trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F76221572C52609D W: GPG error: http://download.opensuse.org Release: The following signatures were invalid: KEYEXPIRED 1460070962 W: GPG error: http://ppa.launchpad.net trusty Release: The following signatures were invalid: BADSIG A9E15C2F2B944FEE Launchpad PPA for Alex Murray W: Failed to fetch http://ppa.launchpad.net/ondrej/php5-5.6/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found W: Failed to fetch http://ppa.launchpad.net/ondrej/php5-5.6/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found E: Some index files failed to download.

   After fixing them (see the above link), it’s working fine

   The following command lists the available ruby versions:

   I’m going to install the latest stable ruby version 2.3.3 because ruby 2.4.0-rc1 still in release candidate.
5. Install Ruby Version
   Using RVM makes the independent management of ruby versions an easy process. The command listed below installs the Ruby version 2.3.3.
   
   teddy@teddy-K43SJ:~$ rvm install 2.3.3 Searching for binary rubies, this might take some time. Found remote file https://rubies.travis-ci.org/ubuntu/14.04/x86_64/ruby-2.3.3.tar.bz2 Checking requirements for ubuntu.

6. Default Ruby Version must be Set up
   In order for the applications to use Ruby, the default ruby version needs to be set. The following command sets Ruby 2.3.3 as default version.
   
   teddy@teddy-K43SJ:~$ rvm use 2.3.3 --default Using /home/teddy/.rvm/gems/ruby-2.3.3

   1 2	teddy@teddy-K43SJ:~$ rvm use 2.3.3 --default Using /home/teddy/.rvm/gems/ruby-2.3.3

7. Confirm ruby version installed
   
   teddy@teddy-K43SJ:~$ ruby -v ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-linux]

   1 2	teddy@teddy-K43SJ:~$ ruby -v ruby 2.3.3p222 (2016-11-21 revision 56859) [x86_64-linux]

   
   We’ve just finished installing ‘Ruby’. Now we’re going to install ‘Rails’
8. Installing Rails
   Rails can be easily installed with the Ruby gem installer.

9. Check the rails version
   Execute the following command to check the rails version and to see if rails has been installed successfully.
   
   teddy@teddy-K43SJ:~$ rails -v Rails 5.0.1

   1 2	teddy@teddy-K43SJ:~$ rails -v Rails 5.0.1

   
   I just installed the latest rails (version 5.0.1). To install certain version (like version 4.2.5), install rails like this:
   
   gem install rails --version=4.2.5

   1	gem install rails --version=4.2.5
