# 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 # Ruby curl -sSL https://rvm.io/mpapis.asc | gpg2 --import - curl -sSL https://get.rvm.io | bash -s stable echo 'gem: --no-document' >> ~/.gemrc # Logout and back in to activate RVM installation rvm install 2.3.1 rvm --default use 2.3.1 # If this error out check https://rvm.io/integration/gnome-terminal gem install bundler mailcatcher # Postgresql sudo su postgres createuser --createdb --superuser -Upostgres $(cat /tmp/username) psql -c "ALTER USER $(cat /tmp/username) WITH PASSWORD 'password';" psql -c "create database discourse_development owner $(cat /tmp/username) encoding 'UTF8' TEMPLATE template0;" psql -c "create database discourse_test owner $(cat /tmp/username) encoding 'UTF8' TEMPLATE template0;" psql -d discourse_development -c "CREATE EXTENSION hstore;" psql -d discourse_development -c "CREATE EXTENSION pg_trgm;" exit # Node curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.1/install.sh | bash # exit the terminal and open it again nvm install 6.2.0 nvm alias default 6.2.0 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 bundle exec rake db:create db:migrate db:test:prepare bundle exec rake autospec # CTRL + C to stop; Optional bundle exec rails s -b 0.0.0.0 # Open browser on http://localhost:3000 and you should see Discourse Create a test account, and enable it with: bundle exec rails c u = User.find_by_id 1 u.activate u.grant_admin! exit Discourse does a lot of stuff async, so it's better to run sidekiq even on development mode: ruby $(mailcatcher) # open http://localhost:1080 to see the emails, stop with pkill -f mailcatcher bundle exec sidekiq -q critical,low,default -d -l log/sidekiq.log # open http://localhost:3000/sidekiq to see the queue, stop with pkill -f sidekiq bundle exec rails server And happy hacking!
