nginx+unicorn 完整配置，主要的是，nginx.conf 和 unicorn.rb 这两个配置文件

nginx 的源码安装 指定passenger目录

源码下载地址  http://nginx.org/en/download.html

编译源码  

./configure --prefix=/srv/nginx/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6 --add-module=/usr/local/rvm/gems/ruby-2.0.0-p598/gems/passenger-5.0.4/ext/nginx/

make  && make install

1.配置nginx文件          sudo vim /opt/nginx/conf/nginx.conf

  # ===== App Server

  }


  # /web/ruby/blogs
  server{
  listen          80;

  server_name     menxu.com;
  keepalive_timeout 5;

  error_log       /home/menxu/web/ruby/blogs/log/nginx_error.log;
  rewrite_log     on;
  
  try_files       $uri/index.html $uri.html $uri @app_server;
  
  location ~* ^/(images|javascripts|stylesheets|img)/{
  access_log      off;
  log_not_found   off;

  break;
  }
  
  location @app_server {
  proxy_set_header Host $host;
  proxy_set_header X-Forwarded-Host $host;
  proxy_set_header X-Forwarded-Server $host;
  proxy_set_header X-Real-IP        $remote_addr;
  proxy_set_header X-Forwarded-For  $proxy_add_x_forwarded_for;
  proxy_buffering  on;
  proxy_redirect  off;
  
      proxy_pass http://app_server;
  }
  }


}

2.创建 config/unicorn.rb 并 配置unicorn 文件    sudo vim /home/menxu/web/ruby/blogs/config/unicorn.rb 

# -*- encoding: utf-8 -*-
user("menxu","menxu")


root_path = File.expand_path '../', File.dirname(__FILE__)
#log
log_file = root_path + '/log/unicorn.log'
err_log  = root_path + '/log/unicorn_error.log'


# process
pid_file = '/tmp/unicorn_padrino.pid'
old_pid = pid_file + '.oldbin'


#thron
socket_file = '/tmp/unicorn_padrino.sock'


worker_processes 2
working_directory root_path
timeout 30


#listen
listen 8080, tcp_nopush: false
listen socket_file, backlog: 1024


pid pid_file
stderr_path err_log
stdout_path log_file


preload_app true


before_exec do |server|
  ENV['BUNDLE_GEMFILE'] = root_path + '/Gemfile'
end


before_fork do |server, worker|
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill('QUIT', File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      puts "Send 'QUIT' signal to unicorn error!"
    end
  end
end

3.编写启动脚本文件  sudo vim ./blog_server.sh

1>安装wrapper 创建带环境的unicorn运行命令

rvm wrapper ruby-2.0.0-p195@blog2 bootup unicorn

2> 编辑启动脚本

#! /bin/sh
# rvm wrapper ruby-2.0.0-p195@blog2 bootup unicorn
UNICORN=/home/menxu/.rvm/bin/bootup_unicorn
CONFIG_FILE=/home/menxu/web/ruby/blogs/config/unicorn.rb
APP_HOME=/home/menxu/web/ruby/blogs


case "$1" in
  start)
  $UNICORN -c $CONFIG_FILE -E production -D
  ;;
  stop)
  kill -QUIT 'cat /tmp/unicorn_padrino.pid'
  ;;
  restart|force-reload)
  kill -USR2 'cat /tmp/unicorn_padrino.pid'
  ;;
  *)
  echo "Usage: $SCRIPTNAME{start|top|restart|force-reload" >&2
  exit 3
  ;;
esac

4.启动命令

sudo ln -s ~/nginx.conf /etc/nginx/conf.d/unicorn.conf # 关联配置
chmod +x ./one.sh # 执行权限
./blog_server.sh # 启动unicorn
sudo service nginx start
