The tutorial work with server by digitalocean.com

Login and create a droplet Ubuntu 16.04x64 1gb cpu & 30gb disk

ssh [e-mail]

sudo apt-get install aptitude

sudo apt-get update

sudo aptitude update

sudo aptitude safe-upgrade

If you have error with locale

sudo locale-gen el_GR.UTF-8

Next exit from server and create ssh connection

ssh-copy-id [e-mail]

sudo adduser deploy

sudo adduser deploy sudo

ssh-copy-id [e-mail]

Edit ssh setting

sudo vim /etc/ssh/sshd_config

Next, we need to find the line that looks like this:

PermitRootLogin yes

Modify this line to "no" like this to disable root login:

PermitRootLogin no

Next, we need to find the line that looks like this:

Port 22

Modify this line between 22 and 50000:

Port 4323

Next, reload service ssh

service ssh restart

Install additional packages from Rails

sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev nodejs

Install git & nginx

sudo apt-get install curl git-core nginx -y

Install version ruby language rbenv

cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

Install ruby build plugin for rbenv

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

Show ruby available versions

rbenv install -l

rbenv install 2.4.0

rbenv global 2.4.0

rbenv rehash

ruby -v

You just add following line to your local ~/.gemrc file (it is in your home folder)

gem: --no-document

Next, install ruby gems version control system

gem install bundler

rbenv rehash

Install Rails

gem install rails -V --no-ri --no-rdoc

rbenv rehash

Create ssh key and copy

ssh-keygen -t rsa

cat ~/.ssh/id_rsa.pub

Visit the github and add ssh, after test it

ssh -T [e-mail]

Next, install Mysql

sudo aptitude update

sudo apt-get install mysql-server mysql-client libmysqlclient-dev

sudo mysql_install_db

sudo mysql_secure_installation

Create mysql database

mysql -u root -p

CREATE DATABASE `app` CHARACTER SET utf8 COLLATE utf8_general_ci;

Add additional gem into Gemfile

group :development do
    gem 'capistrano',         require: false
    gem 'capistrano-rbenv',     require: false
    gem 'capistrano-rails',   require: false
    gem 'capistrano-bundler', require: false
    gem 'capistrano3-puma',   require: false
end

gem 'puma'

Next, install gems

bundle

rbenv rehash

Create files from caristrano

cap install

Copy config/deploy.rb & Capfile files and paste in your rails app

git add -A
git commit -m "Set up Puma, Nginx & Capistrano"
git push origin master

Run capistrano init

cap production deploy:initial

make file /home/deploy/apps/app/shared/config/database.yml

production:
  adapter: mysql2
  pool: 5
  timeout: 5000
  encoding: utf8
  database: app
  username: root
  password: xxxxxxxxx

Set ubuntu environment variable

rails secret

sudo vim /etc/environment

and add this line below

export SECRET_KEY_BASE=abb2e9e094bb8fb1aa216defed455caa0f9

At first time run in apps/app/release/2017456534

RAILS_ENV=production bundle exec rake db:create

Example config/nginx.conf file, paste in your rails app

set nginx virtualhost

sudo rm /etc/nginx/sites-enabled/default

sudo ln -nfs "/home/deploy/apps/app/current/config/nginx.conf" "/etc/nginx/sites-enabled/app"

sudo service nginx restart

At the end, run

If you want only to restart puma server

cap production deploy:restart

After deploy, publish change

git add -A git commit -m "Deploy Message" git push origin master cap production deploy
