Install Process - Installing Ruby on Rails

First step is to install ruby on your linux environment. The commands used here come from

In terminal, run these two commands:

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

For this project I ran Ruby using RVM, so then run

sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
curl -L | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
rvm install 2.1.5
rvm use 2.1.5 --default
ruby -v
echo "gem: --no-ri --no-rdoc" > ~/.gemrc

Install node.js

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

Install Rails

gem install rails

Install depedencies for pg gem **not in online instructions to install rails

sudo apt-get install ruby-dev libpq-dev

Server Setup

Time to set up the server. Move to the LabelMe-Text folder and run the following command:

bundle install
bundle exec rake db:migrate
bundle exec rake db:reset
bundle exec rails s

This starts a copy of the server running on the machine’s localhost. You can access it in your browser at:


Making an Admin

  • Now you want to make an admin user. Go to the website and sign up with the account info for your admin user.
  • From the home page, click on “Create profile”
  • Fill in the account details, check the box agreeing not to scrape the data from the website, and click “Create my account”
  • Then go to terminal and type Ctrl+C to stop the server from running. Run the following commands:
bundle exec rails console.
a = User.find_by_email(“”)
a.update_column(:admin, true)

Leaving server running

If you are using a virtual machine and wish the process to keep running after you close the ‘ssh’ connection, we will use a program called screen to achieve this.

  1. First we need to install screen.

    sudo apt-get install screen
  2. Start the screen program

  3. Navigate to the Label-Me Text folder and start the server again

    bundle exec rails s
  4. While the server is running, detach from the current screen using the following command

    Ctrl + a, d
  5. The server should now run even if you stop the ssh session. To return to the running server terminal, use the command:

    screen -r
