# Discourse Advanced Developer Install Guide

This guide is aimed at advanced Rails developers who have installed their own Rails apps before. If you are new to Rails, you are likely much better off with our **[Discourse Vagrant Developer Guide](VAGRANT.md)**.

Note: If you are developing on a Mac, you will probably want to look at [these instructions](DEVELOPMENT-OSX-NATIVE.md) as well.

# Preparing a fresh Ubuntu install

To get your Ubuntu 16.04 LTS install up and running to develop Discourse and Discourse plugins follow the commands below. We assume an English install of Ubuntu.

    # Basics
    whoami > /tmp/username
    sudo add-apt-repository ppa:chris-lea/redis-server
    sudo apt-get -yqq update
    sudo apt-get -yqq install python-software-properties vim curl expect debconf-utils git-core build-essential zlib1g-dev libssl-dev openssl libcurl4-openssl-dev libreadline6-dev libpcre3 libpcre3-dev imagemagick postgresql postgresql-contrib-9.5 libpq-dev postgresql-server-dev-9.5 redis-server advancecomp gifsicle jhead jpegoptim libjpeg-turbo-progs optipng pngcrush pngquant gnupg2

    # Ruby
    curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
    curl -sSL https://get.rvm.io | bash -s stable
    echo 'gem: --no-document' >> ~/.gemrc

    # exit the terminal and open it again to activate RVM

    rvm install 2.3.4
    rvm --default use 2.3.4 # If this error out check https://rvm.io/integration/gnome-terminal
    gem install bundler mailcatcher

    # Postgresql
    sudo -u postgres -i
    createuser --superuser -Upostgres $(cat /tmp/username)
    psql -c "ALTER USER $(cat /tmp/username) WITH PASSWORD 'password';"
    exit

    # Node
    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash

    # exit the terminal and open it again to activate NVM

    nvm install node
    nvm alias default node
    npm install -g svgo phantomjs-prebuilt


If everything goes alright, let's clone Discourse and start hacking:

    git clone https://github.com/discourse/discourse.git ~/discourse
    cd ~/discourse
    bundle install

    # run this if there was a pre-existing database
    bundle exec rake db:drop
    RAILS_ENV=test bundle exec rake db:drop

    # time to create the database and run migrations
    bundle exec rake db:create db:migrate
    RAILS_ENV=test bundle exec rake db:create db:migrate
    
    # run the specs (optional)
    bundle exec rake autospec # CTRL + C to stop
    
    # launch discourse
    bundle exec rails s -b 0.0.0.0 # open browser on http://localhost:3000 and you should see Discourse

Create an admin account with:

    bundle exec rake admin:create

If you ever need to recreate your database:

    bundle exec rake db:drop db:create db:migrate
    bundle exec rake admin:create
    RAILS_ENV=test bundle exec rake db:drop db:create db:migrate

Discourse does a lot of stuff async, so it's better to run sidekiq even on development mode:

    mailcatcher # open http://localhost:1080 to see the emails, stop with pkill -f mailcatcher
    bundle exec sidekiq # open http://localhost:3000/sidekiq to see queues
    bundle exec rails server

And happy hacking!
