A compilation of several deploy scripts that I use for my rails apps. The stack I use is pretty standart, but it may not suit your needs, so its not for everybody. Current stack includes Nginx, Postgres, rbenv, Redis, Unicorn, Puma, Sidekiq, Memcached, Imagemagick, ElasticSearch, Bower and Monit.

gem 'mina-stack', github: 'div/mina-stack', group: :development 

rails g mina:stack:install 

to create default deploy.rb and servers/production.rb files

In your config/deploy.rb you can configure your stack - you may want to exclude something you may not need e.g. Private Pub, and choose app server - unicorn and puma are supported. It is done by setting server_stack array, example config can be found in examples/deploy.rb.

All the default settings can be fond in lib/mina-stack/defaults.rb and can be overriden in deploy.rb

Servers configs live in config/servers - example config is in examples/production.rb

You can also set with services of your stack will be monitored by Monit - just use monitored array.

Create user on server

sudo adduser deploy sudo adduser deploy sudo su deploy 

then copy your ssh keys

ssh-copy-id deploy@IPADDRESS 

Install all the stack to the server

 bundle exec mina install 

Create folder structure and copy all configs

bundle exec mina setup 

Create db and set password

bundle exec mina postgresql:create_db 

Deploy

bundle exec mina deploy
