Step 1: Build Ruby

1.1) Build Ruby 1.9.3+

• Building Ruby (For RHEL (6.9, 7.1, 7.2, 7.3) and SLES (11 SP4, 12, 12 SP1, 12 SP2))

Note: The available yum / zypper version of Ruby is too low level for the distros.

1.2) Correct the gem environment for a standard user

• RHEL (6.9, 7.1, 7.2, 7.3) and SLES (11 SP4, 12, 12 SP1, 12 SP2)

    export GEM_HOME=/home/<USER>/.gem/ruby
    export PATH=/home/<USER>/.gem/ruby/bin:$PATH
  

Note: Where <USER> is the standard user you are installing under.

Step 2: Installing Ruby on Rails

2.1) Add build dependencies

• RHEL (6.9, 7.1, 7.2, 7.3)

   sudo yum install -y patch make gcc
  

• SLES (11 SP4, 12, 12 SP1, 12 SP2)

   sudo zypper install -y patch make gcc
  

• Ubuntu (16.04, 16.10)

   sudo apt-get install -y ruby ruby-dev patch make gcc zlib1g-dev
  

2.2) Install Ruby on Rails via gem

• RHEL (6.9, 7.1, 7.2, 7.3) and SLES (11 SP4, 12, 12 SP1, 12-SP2)

   gem install rails -v 5.0.2
  

• Ubuntu (16.04, 16.10)

   sudo gem install rails -v 5.0.2
