# Discourse Advanced Developer Install Guide This guide is aimed at advanced Rails developers who have installed their own Rails apps before. 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 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!
