部署 Ubuntu Server + nginx + unicorn 遇到问题

网页一直是 502 Bad Gateway

Ubuntu 12.04 ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-linux] Rails 3.2.13 以上参考 wiki 部署 http://ruby-china.org/wiki/install_ruby_guide 之前一直用 centos 部署 php,最近刚刚开始尝试使用 ubuntu

账号 rails /home/rails/hellworld rails new helloworld ,建立项目,scaffold home, rake db:migrate rails s,利用 WEBrick,ip:3000 访问正常

==========上面很简单,到 unicorn 和 nginx 就难死了,接下来一大堆坑了========== Nginx apt-get install nginx

Unicorn gem install unicorn

搞了两天没搞定,就直接 copy ruby-china 的 unicron.rb,稍微改动一点点

vim /home/rails/hellworld/config/unicorn.rb

module Rails
  class <<self
    def root
      File.expand_path("../..", __FILE__)
    end
  end
end
puts Rails.root
rails_env = ENV["RAILS_ENV"] || "production"

preload_app true
working_directory Rails.root
pid "#{Rails.root}/tmp/pids/unicorn.pid"
stderr_path "#{Rails.root}/log/unicorn.log"
stdout_path "#{Rails.root}/log/unicorn.log"

listen 5000, :tcp_nopush => false

listen "/tmp/unicorn.ruby-china.sock"
worker_processes 6
timeout 120

if GC.respond_to?(:copy_on_write_friendly=)
  GC.copy_on_write_friendly = true
end

before_exec do |server|
  ENV["BUNDLE_GEMFILE"] = "#{Rails.root}/Gemfile"
end

before_fork do |server, worker|
  old_pid = "#{Rails.root}/tmp/pids/unicorn.pid.oldbin"
  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

创建一下

sudo touch /tmp/unicorn.ruby-china.sock
sudo chown rails /tmp/unicorn.ruby-china.sock

’‘’

编辑nginx.conf
sudo vim /etc/nginx/nginx.conf
```BashLexer
user rails;
worker_processes 1;
pid /var/run/nginx.pid;

events {
  worker_connections  1024;
  accept_mutex off;
}

http {
          include mime.types;
  default_type application/octet-stream;

  sendfile on;
  tcp_nopush on;
  tcp_nodelay off;

             text/comma-separated-values
             text/javascript application/x-javascript
             application/atom+xml;




     upstream unicorn_server {
       server unix:/tmp/unicorn.ruby-china.sock fail_timeout=0;
    }

    server {
        listen       80;
        server_name  www.ruby1.com ruby1.com;
        client_max_body_size 4G;
        root /home/rails/hellworld/public;

        #access_log  logs/host.access.log  main;

        location / {
        proxy_redirect off;
        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_pass http://unicorn_server;
        }

    }
}

域名 rub1.com 只是测试的,vim /etc/hosts 都改回指向 127.0.0.1

浏览器测试 网页一直是 502 Bad Gateway

tail -f /var/log/nginx/error.log 跟踪 nginx error.log

rver: www.ruby1.com, request: "GET /favicon.ico HTTP/1.1", upstream: "http://unix:/tmp/unicorn.ruby-china.sock:/favicon.ico", host: "www.ruby1.com"
2013/04/19 06:10:36 [error] 1152#0: *42 connect() to unix:/tmp/unicorn.ruby-china.sock failed (111: Connection refused) while connecting to upstream, client: 10.0.1.88, server: www.ruby1.com, request: "GET /favicon.ico HTTP/1.1", upstream: "http://unix:/tmp/unicorn.ruby-china.sock:/favicon.ico", host: "www.ruby1.com"

111: Connection refused

搞了好久都没法搞定 求高手指点

www.ruby1.com:5000是否正常?

#1 楼 @yangkit 不正常 是不是 unicorn 没启动起来

unicorn -v unicorn v4.6.2

nginx 那边设置监听是 80 端口,所以 www.ruby1.com:5000 tail -f /var/log/nginx/error.log 这里没有任何新的输出信息

#2 楼 @phpnew

curl -I www.ruby1.com:5000

ps aux|grep unicorn_rails

结果贴上来 (先查看一下:log/unicorn.log 日志)

curl -I ruby1.com:5000 curl: (7) couldn't connect to host

curl baidu.com

curl 127.0.0.1:5000 curl: (7) couldn't connect to host

curl 127.0.0.1

502 Bad Gateway

502 Bad Gateway


nginx/1.1.19

================================== ps aux|grep unicorn_rails rails 1096 0.0 0.0 9384 872 pts/1 S+ 06:41 0:00 grep unicorn_rails

================================== cat unicorn.log 是空的 T_T

sudo service unicorn_rails start 先把 unicorn 启动了……

#6 楼 @phpnew unicorn 没有启动

RAILS_ENV=production bundle exec unicorn_rails -c config/unicorn.rb -E production -D

sudo service unicorn status unicorn: unrecognized service 确实没启动

但是 unicorn -v 有结果,说明有安装 cat log/unicorn.log 没输出结果

vim Gemfile gem 'unicorn' 有,有去注解

vim /home/rails/hellworld/config/unicorn.rb 看顶楼

nginx.conf

upstream unicorn_server { server unix:/tmp/unicorn.ruby-china.sock fail_timeout=0; }

proxy_pass http://unicorn_server;

#9 楼 @blacktulip sudo service unicorn status unicorn: unrecognized service "unicorn: unrecognized service" google 没找到有答案 stackoverflow 也没找到,555

#9 楼 @phpnew 为什么不把 unicorn 添加到 Gemfile?重新bundle install

#10 楼 @phpnew 因为你/etc/init.d/目录下没有写 unicorn 的启动脚本,所以识别不了这个服务

bundle install 装了,在之前部署的时候就 gem install unicorn 现在又在 helloworld 根下执行了几次 bundle install

RAILS_ENV=production bundle exec unicorn_rails -c config/unicorn.rb -E production -D

运行一下,停顿一下, 然后就下一个 $

反复 sudo reboot,然后执行 RAILS_ENV=production bundle exec unicorn_rails -c config/unicorn.rb -E production -D 网页还是 502

@yangkit 是这样添加吗

Already running on PID:1226 就是说 unicorn 已经可以启动咯?

ps aux|grep unicorn_rails

如果已经确认启动,

curl www.ruby1.com:5000

如果无法访问,查看一下 unicorn.log 和 production.log,看看是否有错误 如果可以访问,就是 nginx 反向代理配置出了问题

@phpnew 重新排版一下先

#15 楼 @yangkit ’ps aux|grep unicorn_rails`

kill -USR2 1307 等等,把所有 pid 都 kill 掉,然后重新

 RAILS_ENV=production bundle exec unicorn_rails -c config/unicorn.rb -E production -D
/home/rails/hellworld
master failed to start, check stderr log for details
还是有pid。。。
cat log/unicorn.log 查看错误信息

#16 楼 @yangkit 14 楼已重新编辑了

#15 楼 @yangkit 第一次看到结果了 不过是 404

网页打开 80 端口还是 502 Bad Gateway

kill -0 1341

如果进程不存在就把 /home/rails/hellworld/tmp/pids/unicorn.pid 文件删除,在重新启动

#19 楼 @phpnew 访问其他的 GET 路径试一试

#21 楼 @yangkit

我记得 nginx.conf 里头 server root /home/rails/hellworld/public;

其他 get 路径

访问 5000 端口,就不是 nginx 配置问题了 所有路径都 404? public/robots.txt 是否存在?

@yangkit 真实存在

#26 楼 @phpnew 更正一下,rails 项目是否处理静态文件请求和配置有关 如: production.rb 中的配置:

# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false

不建议用 unicorn 处理静态文件

you generally want to serve static files with nginx since neither Unicorn nor Rainbows! is optimized for it at the moment

RAILS_ENV=production bundle exec rake middleware
use Rack::Cache
use Rack::Lock
use #<ActiveSupport::Cache::Strategy::LocalCache::Middleware:0x00000004054de0>
use Rack::Runtime
use Rack::MethodOverride
use ActionDispatch::RequestId

可以看到,rails 没有启用ActionDispatch::Static middleware

启动脚本参考这个链接:因为可能会涉及到RVMbundler环境的配置 http://blog.kiskolabs.com/post/722322392/unicorn-init-scripts
