Question

我的Rails应用程序在我的本地开发环境（Mac）中运行良好。我将代码推送到测试服务器，并尝试手动启动它，但出现错误。详细信息是：

OS: Ubuntu 18.04
Rails 5.2.3
Ruby 2.6.3
Puma
Webpacker
Nginx

我的/etc/nginx/sites-enabled/myfqdn.com.conf文件：

upstream puma {
  server unix:///home/test/shared/tmp/sockets/test-puma.sock;
}

server {
  listen 80 default_server deferred;
  server_name test.xxxxxx.com;

  root /home/amptest/public;
  access_log /home/test/log/nginx.access.log;
  error_log /home/test/log/nginx.error.log info;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @puma;
  location @puma {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://puma;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 10M;
  keepalive_timeout 10;
}

我创建了目录：

/home/myapp/shared
/home/myapp/shared/tmp
/home/myapp/shared/tmp/sockets
/home/myapp/shared/tmp/pids

我的config / puma.rb文件如下：

threads_count = ENV.fetch("RAILS_MAX_THREADS") { 5 }
threads threads_count, threads_count
port ENV.fetch("PORT") { 3000 }
environment ENV.fetch("RAILS_ENV") { "development" }
plugin :tmp_restart

在我的.bashrc中，我有：

export RAILS_ENV='test'

在我的Gemfile中，我有：

gem 'puma'
gem 'webpacker'

我跑了

bundle install

没有错误

成功进行了数据库迁移：

rake db:migrate

并播种数据库：

rake db:seed

然后我做了：

bundle exec rake assets:precompile

正确完成的操作

bundle exec rake assets:precompile

但是我尝试去test.xxxxxx.com，却收到错误消息“东西错了”。

nginx错误日志显示：

2019/09/10 05:38:21 [crit] 1192#1192: *1 connect() to unix:///home/test/shared/tmp/sockets/test-puma.sock failed (2: No such file or directory) while connecting to upstream, client: xx.xxx.xxx.xxxx, server: test.xxxxxx.com, request: "GET / HTTP/1.1", upstream: "http://unix:///home/test/shared/tmp/sockets/test-puma.sock:/", host: "test.xxxxxx.com"

因此，我缺少一个或更多个步骤，包括确保Puma正确启动所需的操作。有什么想法吗？

Answer 1

这是因为该应用程序的Rails服务器未运行。您从未运行过rails server命令。

如果您将此用于测试/开发目的，请考虑以下事项：

在端口3001 rails s -b 0.0.0.0 -p 3001上启动Rails服务器
然后在nginx配置中使用Rails服务器URL反向代理请求：
```
proxy_pass http://127.0.0.1:3001
```

如果将其用于生产，则考虑使用Passenger，您会看到乘客的安装情况docs here
