nginx + unicorn 部署 rails 项目，顾名思义要先安装nginx和unicorn
一 安装
安装nginx: sudo apt-get install nginx
安装unicorn: gem install unicorn
二 配置
1 在你项目的config文件夹下添加一个unicorn.rb文件，添加代码（样列：http://unicorn.bogomips.org/examples/unicorn.conf.rb）
我的如下：
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 true 10 working_directory Rails.root 11 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 30 18 19 GC.respond_to?(:copy_on_write_friendly=) and 20 GC.copy_on_write_friendly = true 21 22 before_fork do |server, worker| 23 defined?(ActiveRecord::Base) and 24 ActiveRecord::Base.connection.disconnect! 25 end 26 27 after_fork do |server, worker| 28 defined?(ActiveRecord::Base) and 29 ActiveRecord::Base.establish_connection 30 end
2 配置nginx
sudo apt-get install nginx默认安装在/etc/nginx目前下
在/etc/nginx/conf.d目录下创建文件：project_name.conf 添加代码(样例： http://unicorn.bogomips.org/examples/nginx.conf )
我的如下：
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 }
注意：
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; }
这两个的unicorn.project-name.sock的路径必须是一致的!!!
2
upstream project_name_backend 这里的project_name_backend 和 proxy_pass http://project_name_backend; 这里的project_name_backend是一致的!!!
