はじめに

まぁそのまんま。
こちらのRubyonRails編。

Ruby 2.4.2
Ruby on Rails 5.1.4
なり。

Amazon Linux AMI+Nginx+Unicorn
やで。

インストールなど

sudo yum update
sudo yum -y install git
sudo yum install nodejs --enablerepo=epel
git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
source ~/.bash_profile
sudo yum install gcc openssl-devel readline-devel sqlite-devel
rbenv install 2.4.2
rbenv global 2.4.2
gem update --system
gem install --no-ri --no-rdoc rails
gem install bundler
gem install sqlite3
gem install unicorn
rbenv rehash
rails -v
rails new /var/www/html/sample
sudo mkdir /var/run/unicorn
sudo chmod 777 /var/run/unicorn
sudo chown -R nginx:ec2-user /var/www/html
sudo chmod 2777 /var/www -R

まぁ、だいぶ時間がかかりまっせ。

sample/config/unicorn.rbを作成

application = 'sample'

worker_processes 2
timeout 15

pid "/var/run/unicorn/unicorn_#{application}.pid"
listen "/var/run/unicorn/unicorn_#{application}.sock"

preload_app true

before_fork do |server, worker|
  Signal.trap 'TERM' do
  puts 'Unicorn master intercepting TERM and sending myself QUIT instead'
  Process.kill 'QUIT', Process.pid
  end

  defined?(ActiveRecord::Base) and
  ActiveRecord::Base.connection.disconnect!end

after_fork do |server, worker|
  Signal.trap 'TERM' do
  puts 'Unicorn worker intercepting TERM and doing nothing. Wait for master to send QUIT'
  end

  defined?(ActiveRecord::Base) and
  ActiveRecord::Base.establish_connection
end

stderr_path File.expand_path('log/unicorn.log', ENV['RAILS_ROOT'])
stdout_path File.expand_path('log/unicorn.log', ENV['RAILS_ROOT'])

起動

bundle exec unicorn_rails -c config/unicorn.rb -E development -D

OSの再起動対応

~/.bashrcに追記

sudo mkdir -p /var/run/unicorn && sudo chmod 777 /var/run/unicorn

/etc/nginx/conf.d/sample.conf作成

upstream unicorn {
  server unix:/var/run/unicorn/unicorn_sample.sock;
}
server {
    listen 8080;
    server_name localhost;
    root /var/www/html/sample;

    access_log /var/log/nginx/myapp_access.log;
    error_log /var/log/nginx/myapp_error.log;

    try_files $uri/index.html $uri @unicorn;
    location @unicorn {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_pass http://unicorn;
    }
}

PHPを80で動かしてる都合上8080でごわす。

Nginx再起動

sudo service nginx restart

いじょー
Security Groupで8080はあけておきましょうね。

追記

こちらを参考にinit.d作っておくと便利ですね。
