nginx + unicorn 部署rails项目

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!!!
