|||
|
||||
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
|
||||
# Preparing a fresh Ubuntu install
|
||||
|
||||
1. Install and configure PostgreSQL 9.3+.
|
||||
1. Run `postgres -V` to see if you already have it.
|
||||
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 2.8.12+.
|
||||
1. Run `redis-server -v` to see if you already have it.
|
||||
3. Install ImageMagick
|
||||
4. Install libxml2, libpq-dev, g++, gifsicle, libjpeg-progs and make.
|
||||
5. Install Ruby 2.1.3 and Bundler.
|
||||
6. Clone the project and bundle.
|
||||
To get your Ubuntu 16.04 LTS install up and running to develop Discourse and Discourse plugins follow the commands below. We assume and English install of Ubuntu.
|
||||
|
||||
## Before you start Rails
|
||||
# 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-progs optipng pngcrush pngquant
|
||||
|
||||
1. `bundle install`
|
||||
2. Start up Redis by running `redis-server`
|
||||
3. `bundle exec rake db:create db:migrate db:test:prepare`
|
||||
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!

# Ruby
|
||||
curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
|
||||
\curl -sSL https://get.rvm.io | bash -s stable
|
||||
echo 'gem: --no-document' >> ~/.gemrc
|
||||
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
|
||||
|
||||
|
||||
# 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 imagemagick
|
||||
|
||||
## 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
|
||||
|
||||
Configure so that the vagrant user doesn't need to provide username and password.
|
||||
|
||||
apt-get -yqq install postgresql postgresql-contrib-9.3 libpq-dev postgresql-server-dev-9.3
|
||||
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;"
|
||||
# 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;"
|
||||
|
||||
# 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
|
||||
|
||||
Edit /etc/postgresql/9.3/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
|
||||
If everything goes alright, let's clone Discourse and start hacking:
|
||||
|
||||
## Redis
|
||||
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
|
||||
bundle exec rails server # Open browser on http://localhost:3000 and you should see Discourse
|
||||
|
||||
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
|
||||
Create a test account, and enable it with:
|
||||
|
||||
## Sending email (SMTP)
|
||||
bundle exec rails c
|
||||
u = User.find_by_id 1
|
||||
u.activate
|
||||
u.grant_admin!
|
||||
exit
|
||||
|
||||
By default, development.rb will attempt to connect locally to send email.
|
||||
Discourse does a lot of stuff async, so it's better to run sidekiq even on development mode:
|
||||
|
||||
```rb
|
||||
config.action_mailer.smtp_settings = { address: "localhost", port: 1025 }
|
||||
```
|
||||
ruby $(mailcatcher) # open http://localhost:1080 to see the emails, stop with pkill -f mailcatcher
|
||||
bundle exec sidekiq -d -l log/sidekiq.log # open http://localhost:3000/sidekiq to see the queue, stop with pkill -f sidekiq
|
||||
bundle exec rails server
|
||||
|
||||
Set up [MailCatcher](https://github.com/sj26/mailcatcher) so the app can intercept
|
||||
outbound email and you can verify what is being sent.
|
||||
|
||||
Note also that mail is sent asynchronously by Sidekiq, so you'll need to have it running to process jobs. Run it with this command:
|
||||
|
||||
```
|
||||
bundle exec sidekiq
|
||||
```
|
||||
|
||||
## 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
|
||||
And happy hacking!
