# 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. ## First Steps 1. Install and configure PostgreSQL 9.1+. Make sure that the server's messages language is English; this is [required](https://github.com/rails/rails/blob/3006c59bc7a50c925f6b744447f1d94533a64241/activerecord/lib/active_record/connection_adapters/postgresql_adapter.rb#L1140) by the ActiveRecord Postgres adapter. 2. Install and configure Redis 2+. 3. Install libxml2, g++, and make. 4. Install Ruby 1.9.3 and Bundler. 5. Clone the project and bundle. 6. Copy `config/database.yml.development-sample` to `config/database.yml`. Copy `config/redis.yml.sample` to `config/redis.yml`. Edit the files to point to your postgres and redis instances. 7. Create the "vagrant" user and the development and test databases in postgres. See the postgres section in "Building your own Vagrant VM", below. 8. Install the seed data to set up an admin account and meta topic: `psql DATABASE_NAME < pg_dumps/production-image.sql` ## Before you start Rails 1. `bundle install` 2. `bundle exec rake db:migrate db:test:prepare db:seed_fu` 4. Try running the specs: `bundle exec rake autospec` 5. `bundle exec rails server` You should now be able to connect to rails on [http://localhost:3000](http://localhost:3000) - try it out! The seed data includes a pinned topic that explains how to get an admin account, so start there! Happy hacking! # Building your own Vagrant VM Here are the steps we used to create the **[Vagrant Virtual Machine](VAGRANT.md)**. They might be useful if you plan on setting up an environment from scratch on Linux: ## Base box Vagrant version 1.1.2. With this Vagrantfile: Vagrant::Config.run do |config| config.vm.box = 'precise32' config.vm.box_url = 'http://files.vagrantup.com/precise32.box' config.vm.network :hostonly, '192.168.10.200' if RUBY_PLATFORM =~ /darwin/ config.vm.share_folder("v-root", "/vagrant", ".", :nfs => true) end end vagrant up vagrant ssh ## Some basic setup: sudo su - ln -sf /usr/share/zoneinfo/Canada/Eastern /etc/localtime apt-get -yqq update apt-get -yqq install python-software-properties apt-get -yqq install vim curl expect debconf-utils git-core build-essential zlib1g-dev libssl-dev openssl libcurl4-openssl-dev libreadline6-dev libpcre3 libpcre3-dev ## Unicode echo "export LANGUAGE=en_US.UTF-8" >> /etc/bash.bashrc echo "export LANG=en_US.UTF-8" >> /etc/bash.bashrc echo "export LC_ALL=en_US.UTF-8" >> /etc/bash.bashrc export LANGUAGE=en_US.UTF-8 export LANG=en_US.UTF-8 export LC_ALL=en_US.UTF-8 locale-gen en_US.UTF-8 dpkg-reconfigure locales ## RVM and Ruby apt-get -yqq install libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion pkg-config curl build-essential git su - vagrant -c "sudo bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)" adduser vagrant rvm source /etc/profile.d/rvm.sh su - vagrant -c "rvm pkg install libyaml" su - vagrant -c "rvm install 2.0.0-turbo" su - vagrant -c "rvm use 2.0.0-turbo --default" echo "gem: --no-document" >> /etc/gemrc su - vagrant -c "echo 'gem: --no-document' >> ~/.gemrc" ## Postgres 9.1 Configure so that the vagrant user doesn't need to provide username and password. apt-get -yqq install postgresql postgresql-contrib-9.1 libpq-dev postgresql-server-dev-9.1 su - postgres createuser --createdb --superuser -Upostgres vagrant psql -c "ALTER USER vagrant WITH PASSWORD 'password';" psql -c "create database discourse_development owner vagrant encoding 'UTF8' TEMPLATE template0;" psql -c "create database discourse_test owner vagrant encoding 'UTF8' TEMPLATE template0;" psql -d discourse_development -c "CREATE EXTENSION hstore;" psql -d discourse_development -c "CREATE EXTENSION pg_trgm;" Edit /etc/postgresql/9.1/main/pg_hba.conf to have this: local all all trust host all all 127.0.0.1/32 trust host all all ::1/128 trust host all all 0.0.0.0/0 trust # wide-open Load the seed data (as vagrant user): psql -d discourse_development < pg_dumps/development-image.sql (You may wish to try the `production-image.sql` file for a good seed for a production database.) ## Redis sudo su - mkdir /tmp/redis_install cd /tmp/redis_install wget http://redis.googlecode.com/files/redis-2.6.7.tar.gz tar xvf redis-2.6.7.tar.gz cd redis-2.6.7 make make install cd utils ./install_server.sh # Press enter to accept all the defaults /etc/init.d/redis_6379 start ## Phantomjs Needed to run javascript tests. cd /usr/local/share wget https://phantomjs.googlecode.com/files/phantomjs-1.8.2-linux-i686.tar.bz2 tar xvf phantomjs-1.8.2-linux-i686.tar.bz2 rm phantomjs-1.8.2-linux-i686.tar.bz2 ln -s /usr/local/share/phantomjs-1.8.2-linux-i686/bin/phantomjs /usr/local/bin/phantomjs
