Below versions of Ruby on Rails are available in respective distributions at the time of creation of these build instructions:

• SLES (12 SP3, 15)
• Ubuntu (16.04, 18.04)

Step 1: Build Ruby

1.1) Build Ruby

• Building Ruby (For RHEL (6.10, 7.3, 7.4, 7.5) and SLES (12 SP3, 15))

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 (6.10, 7.3, 7.4, 7.5) and SLES (12 SP3, 15)

    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 (6.10, 7.3, 7.4, 7.5)

   sudo yum install -y patch make gcc
  

• SLES (12 SP3, 15)

   sudo zypper install -y patch make gcc
  

• Ubuntu (16.04, 18.04)

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

2.2) Install Ruby on Rails via gem

• RHEL (6.10, 7.3, 7.4, 7.5) and SLES (12 SP3, 15)

   gem install rails -v 5.2.1
  

• Ubuntu (16.04, 18.04)
