Install passenger (e.g. Ubuntu Trusty like this:)

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 \
  --recv-keys 561F9B9CAC40B2F7
sudo apt-get install -y apt-transport-https ca-certificates

# Add APT repository
sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main > /etc/apt/sources.list.d/passenger.list'
sudo apt-get update

# Install Passenger + Nginx (try apache if you would rather not change
# nginx)
sudo apt-get install -y nginx-extras passenger

Setup Postgres

sudo apt-get install postgresql-9.4 #specify version!!
sudo -u postgres psql
postgres=# CREATE USER metamaps WITH PASSWORD 'mycoolpassword' CREATEDB;
postgres=# CREATE DATABASE metamap002_production OWNER metamaps;
postgres=# \q

Install system-wide rvm:

sudo gpg --keyserver hkp://keys.gnupg.net \
  --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
\curl -sSL https://get.rvm.io | sudo bash -s stable
echo "gem: --no-ri --no-rdoc" | sudo tee -a /etc/gemrc

Create user and setup gemsets for that user

sudo adduser --disabled-password metamaps
sudo adduser metamaps rvm

Clone github repo and install gems

sudo su - metamaps
rvm user gemsets
git clone https://github.com/metamaps/metamaps \
  --branch instance/mycoolinstance
rvm install $(cat metamaps/.ruby-version) #ensure ruby is installed
cd metamaps
gem install bundle
bundle install

Connect rails database

Run this in the metamaps directory, still as metamaps:

# fill in DB_* values, and realtime server at least. Change the 
# SECRET_KEY_BASE to something new. Ctrl+X to save/exit from nano.
cp .example-env .env
nano .env

# Set up environment variables in your current session
source .env
export RAILS_ENV=production
export NODE_ENV=production

# create, load schema, seed
rails db:setup

Install node & ES6 modules

sudo aptitude install nodejs npm
sudo ln -s /usr/bin/nodejs /usr/bin/node
npm install

Precompile assets

This step depends on running npm install first; assets:precompile will run NODE_ENV=production npm run build, and the build-apidocs.sh script requires the raml2html npm package.

bin/build-apidocs.sh
rails assets:precompile
rails perms:fix

Nginx and SSL

Now set up nginx - config stored on Linode, including relevant environment variables.

Get an SSL certificate and encrypt it for the realtime video.

And finally

passenger-config restart-app /home/metamaps/metamaps

If this command fails, it may be helpful for debugging to run a test server to see what problems show up:

RAILS_ENV=production rails server

Realtime server:

sudo npm install -g forever
(crontab -u metamaps -l 2>/dev/null; echo "@reboot $(which forever) --append -l /home/metamaps/logs/forever.realtime.log start /home/metamaps/metamaps/realtime/realtime-server.js") | crontab -u metamaps -

mkdir -p /home/metamaps/logs
forever --append -l /home/metamaps/logs/forever.realtime.log \
  start /home/metamaps/metamaps/realtime/realtime-server.js

Upstart service for delayed_worker:

Put the following code into /etc/init/metamaps_delayed_worker.conf:

description "Delayed Jobs Worker for Metamaps"

start on runlevel [2345]
stop on runlevel [!2345]

setuid metamaps
setgid metamaps
chdir /home/metamaps/metamaps

env HOME=/home/metamaps
env PATH="/usr/local/rvm/gems/ruby-2.3.0@metamaps/bin:/usr/local/rvm/gems/ruby-2.3.0@global/bin:/usr/local/rvm/rubies/ruby-2.3.0/bin:/usr/local/rvm/bin:/usr/local/bin:/usr/bin:/bin"
env GEM_PATH="/usr/local/rvm/gems/ruby-2.3.0@metamaps:/usr/local/rvm/gems/ruby-2.3.0@global"
env RAILS_ENV="production"

respawn
respawn limit 3 30

exec bundle exec rails jobs:work

Then start the service and check the last ten lines of the log file to make sure it's running OK:

sudo service metamaps_delayed_job start
tail /var/log/upstart/metamaps_delayed_job.log
