Raw Blame History

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 bundler
RAILS_ENV=production 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
bundle exec 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 calls npm install and bin/build-apidocs.sh, both of which require node_modules to be installed. We suggest you run the commands separately this time to better catch any errors.

npm run build
bin/build-apidocs.sh
bundle exec rails assets:precompile
bundle exec rails perms:fix

Nginx and SSL

We recommand using Passenger + Nginx to serve your website. You can contact us for our nginx configuration.

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 env NODE_REALTIME_PORT=5000 $(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
env NODE_REALTIME_PORT=5000 forever --append \
  -c /home/metamaps/metamaps/node_modules/.bin/babel-node \
  -l /home/metamaps/logs/forever.realtime.log \
  start /home/metamaps/metamaps/realtime/realtime-server.js

Upstart service for delayed_worker:

If your system uses upstart for init scripts, put the following code into /etc/init/metamaps_delayed_job.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

Systemd service for delayed_worker:

If your system uses systemd for init scripts, ptu the following code into /etc/systemd/system/metamaps_delayed_job.service:

[Unit]
Description=metamaps delayed job service
After=network-online.target

[Service]
ExecStart=/usr/local/rvm/gems/ruby-2.3.0@metamaps/bin/bundle exec rails jobs:work
