Building Ruby on Rails

ATTENTION!!! This package uses Log4j. Please see details here, for the updates on security vulnerabilities.

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

  • Ubuntu 18.04 has 4.2.10
  • Ubuntu 20.04 has 5.2.3
  • Ubuntu 21.04 has 6.0.3.5
  • SLES (15 SP2, 15 SP3) has 5.1.4

The instructions provided below specify the steps to build Rails version 6.1.4.1 on Linux on IBM Z for following distributions:

  • RHEL (7.8, 7.9, 8.2, 8.3, 8.4)
  • SLES (12 SP5, 15 SP2, 15 SP3)
  • Ubuntu (18.04, 20.04, 21.04)

General Notes:

  • When following the steps below please use a standard permission user unless otherwise specified.
  • A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

Step 1: Build Ruby

1.1) Build Ruby

  • Building Ruby (For RHEL (7.8, 7.9, 8.2, 8.3, 8.4) , SLES 12 SP5)

1.2) Correct the gem environment for a standard user

  • RHEL (7.8, 7.9, 8.2, 8.3, 8.4) , SLES 12 SP5 
       export GEM_HOME=$HOME/.gem/ruby
   export PATH=$HOME/.gem/ruby/bin:$PATH

Step 2: Install Ruby on Rails

2.1) Add build dependencies

  • RHEL (7.8, 7.9)

    sudo yum install -y patch make gcc  gcc-c++ npm

  • Install sqllite 3.8 (Only for RHEL 7.x)

    wget https://www.sqlite.org/2019/sqlite-autoconf-3280000.tar.gz
tar zxvf sqlite-autoconf-3280000.tar.gz
cd sqlite-autoconf-3280000
./configure
make
sudo make install
sqlite3 --version

  • RHEL (8.2, 8.3, 8.4)

    sudo yum groupinstall -y 'Development Tools'
sudo yum install -y zlib zlib-devel ruby-devel patch gcc-c++ npm sqlite-devel

  • SLES 12 SP5

    sudo zypper install -y patch make gcc shared-mime-info gcc-c++ libxslt-devel npm14 timezone

  • SLES (15 SP2, 15 SP3)

    sudo zypper install -y ruby2.5 ruby2.5-devel gcc zlib-devel gawk make patch tar gzip shared-mime-info sqlite-devel gcc-c++ libxslt-devel npm14

  • Ubuntu (18.04, 20.04)

    sudo apt-get update
sudo apt-get install -y ruby ruby-dev make gcc zlib1g-dev patch build-essential libsqlite3-dev  npm tzdata

  • Ubuntu 21.04

    sudo apt-get update
sudo apt-get install -y ruby ruby-dev make gcc zlib1g-dev patch ruby-nokogiri build-essential libsqlite3-dev  npm tzdata

2.2) Install Ruby on Rails via gem

   sudo gem install rake                   # For Ubuntu
   gem install rails -v 6.1.4.1              # For RHEL and SLES 12.x
   sudo gem install rails -v 6.1.4.1         # For Ubuntu and SLES 15.x
   sudo ln -sf /usr/lib64/ruby/gems/2.5.0/gems/railties-6.1.4.1/exe/rails /usr/bin/rails   # For SLES 15.x

2.3) Ruby on Rails is now installed. Verify version with command rails -v

  • (Output)

    Rails 6.1.4.1

2.4) Verification

  • Install NodeJS

    cd $SOURCE_ROOT
wget  https://nodejs.org/download/release/v16.3.0/node-v16.3.0-linux-s390x.tar.gz
tar xvf node-v16.3.0-linux-s390x.tar.gz
export PATH=$SOURCE_ROOT/node-v16.3.0-linux-s390x/bin:$PATH
node -v

  • Install required dependencies

    sudo gem install  bundler  # For Ubuntu and SLES 15.x
gem install bundler  # For RHEL 7.x and SLES 12.x
sudo npm install -g yarn

  • Create a new Rails application and start the web server

    rails new myapp
cd myapp/
bin/rails server &

  • After starting Rails server, go to http://localhost:3000

    curl http://127.0.0.1:3000
