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
# make sure you have development headers for postgres. The package name might be different on your distribution.
sudo apt-get install libpq-dev
sudo -u postgres psql
postgres=# CREATE USER metamaps WITH PASSWORD 'mycoolpassword' CREATEDB;
postgres=# CREATE DATABASE metamaps_production OWNER metamaps;
postgres=# \q
On some deploys, we have had problems with unicode encoding when trying to run db:setup. Running the commands in this Github gist resolved the issue: https://gist.github.com/amolkhanorkar/8706915. Try this link if you have problems
Install Node for javascript building
# this first line lets us use up-to-date versions of node.js
# instead of the old versions in the Ubuntu repositories
curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node
Install redis server for action cable
sudo apt-get install redis-server
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
cat metamaps/.ruby-version
The last line tells you what version of ruby you need to install. For example, at the time of writing the version is 2.3.0. As your normal sudo-enabled user, run
sudo rvm install 2.3.0
Now switch back to the metamaps user and continue
cd /home/metamaps/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
Precompile assets
Note that rails assets:precompile will normally call npm install and bin/build-apidocs.sh as part of its process. Both of these latter commands require npm install to be run first. We suggest you run all five commands separately this time (like below) to better catch any errors. In the future, you won't need to run the second and third commands separately.
npm install
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
(sudo crontab -u metamaps -l 2>/dev/null; echo "@reboot NODE_REALTIME_PORT=5000 /usr/bin/forever --minUptime 1000 --spinSleepTime 1000 --append -l /home/metamaps/logs/forever.realtime.log -c /home/metamaps/metamaps/node_modules/.bin/babel-node --workingDir /home/metamaps/metamaps start /home/metamaps/metamaps/realtime/realtime-server.js") | sudo crontab -u metamaps
mkdir -p /home/metamaps/logs
/usr/bin/forever --minUptime 1000 --spinSleepTime 1000 \
--append -l /home/metamaps/logs/forever.realtime.log \
-c /home/metamaps/metamaps/node_modules/.bin/babel-node \
--workingDir /home/metamaps/metamaps \
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

Environment=RAILS_ENV=production
[Install]
WantedBy=multi-user.target
Then start the service and check the last ten lines of the log file to make sure it's running OK:
sudo systemctl start metamaps_delayed_job
# ??? how the heck do you check systemd logs??
initial service startup
sudo systemctl enable metamaps_delayed_job
sudo systemctl start metamaps_delayed_job
sudo systemctl status metamaps_delayed_job
after changing
sudo systemctl daemon-reload
sudo systemctl restart metamaps_delayed_job
sudo systemctl status metamaps_delayed_job
