We will set up Ruby on Rails in Ubuntu 14.04 operating system.
There are three methods to install Ruby:
- Using rbenv (recommended)
- Using rvm
- From source
We will install using rbenv as it is the most recommended way.
First we will install some dependencies for Ruby:
sudo apt-get update sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev
libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev
libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev nodejsInstall rbenv
Installing rbenv is a simple two way process. First rbenv will be installed and then ruby-build.
Follow the following commands:
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc\
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELLgit clone git://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELLThe above command will install rbenv in your home directory and will set the appropriate environment variables.
Install Ruby
Install Ruby using following commands:
- rbenv install -v 2.2.3
- rbenv global 2.2.3
To disable Rubygems which generate local documentation for each gem that you install, use following command:
echo "gem: --no-document" > ~/.gemrc Now you need to install bundler gem to manage application dependencies with following command.
gem install bundler Install Rails
Install Rails using following command,
gem install rails You can specify the version of Rails which you want to install using -v option in the above command.
Now we will run rehash sub-command. This will install shims for all Ruby executables known to rbenv, which allow you to use executables.
rbenv rehash To verify the installed Rails version, use the following command.
rails -v 
Install JavaScript Runtime
Some Rails features like Asset Pipeline, depends on JavaScript runtime. To get this functionality, we need to install Node.js.
sudo add-apt-repository ppa:chris-lea/node.js
- sudo apt-get update
- sudo apt-get install nodejs
Now you have successfully installed Ruby on Rails on your system.
Install Database
Rails default database is Sqlite3. If you want to use some other database due to any reason, then you need to install it.
Here, we will install MySQL server as our database.
sudo apt-get install mysql-server mysql-client libmysqlclient-dev After this, install mysql2 gem, with following command.
gem install mysql2 Now you can easily use MySQL with Rails in your system.
