Deploying a rails project using nginx + unicorn

Nginx + unicorn to deploy the rails project. As the name suggests, nginx and unicorn must be installed first.

1. Installation

Install nginx: sudo apt-Get install nginx

Install Unicorn: Gem install unicorn

Ii. Configuration

1. Add a unicorn. RB file under the config folder of your project and add code (sample column: http://unicorn.bogomips.org/examples/unicorn.conf.rb)

Mine is as follows:

 1 module Rails 2   class << self 3     def root 4       File.expand_path(__FILE__).split("/")[0..-3].join("/") 5     end 6   end 7 end 8  9 preload_app true10 working_directory Rails.root11 pid "#{Rails.root}/tmp/pids/unicorn.pid"12 stderr_path "#{Rails.root}/log/unicorn.log"13 stdout_path "#{Rails.root}/log/unicorn.log"14 15

16 worker_processes 2

17 timeout 3018 19 GC.respond_to?(:copy_on_write_friendly=) and 20   GC.copy_on_write_friendly = true21 22 before_fork do |server, worker|23   defined?(ActiveRecord::Base) and 24     ActiveRecord::Base.connection.disconnect!25 end26 27 after_fork do |server, worker|28   defined?(ActiveRecord::Base) and 29     ActiveRecord::Base.establish_connection30 end

2 configure nginx

Sudo apt-Get install nginx is installed under/etc/nginx by default.

Create the file project_name.conf in the/etc/nginx/CONF. d directory to add code (example: http://unicorn.bogomips.org/examples/nginx.conf)

Mine is as follows:

 1 upstream project_name_backend { 2   server unix:/path_to_project/tmp/sockets/unicorn.project-name.sock fail_timeout=0; 3 } 4  5 server { 6   listen 80; 7   server_name localhost; 8   root /path_to_project/public; 9 10   location ^~ /assets/ {11     gzip_static on;12     expires max;13     add_header Cache-Control public;14   }15 16   try_files $uri/index.html $uri @unicorn;17   location @unicorn {18     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;19     proxy_set_header Host $http_host;20     proxy_redirect off;21     proxy_pass http://project_name_backend;22   }23 24   error_page 500 502 503 504 /500.html;25   client_max_body_size 4G;26   keepalive_timeout 10;27 }

Note:

1

listen "#{Rails.root}/tmp/sockets/unicorn.project-name.sock", :backlog => 64

upstream project_name_backend {    server unix:/path_to_project/tmp/sockets/unicorn.project-name.sock fail_timeout=0;  }

These two unicorn. project-name.sock paths must be consistent !!!

2

Upstream project_name_backend andProxy_pass http: // project_name_backend; The project_name_backend here is consistent !!!
