Question

在使用capistrano3部署我的rails应用程序之后，我的应用程序第一次运行良好，但是有时我在nginx.error.log中遇到了此错误：

unix:/var/www/appname/shared/tmp/sockets/puma.sock failed (111: Connection refused) while connecting to upstream

这是我在/ etc / nginx / site-available /

中的conf文件

upstream puma_appname_production { 
  server unix:/var/www/appname/shared/tmp/sockets/puma.sock 
  fail_timeout=0;
}

server {
  listen 80;
  # server_name domaine.com;
  root /var/www/appname/current/public;
  try_files $uri/index.html $uri @puma_appname_production;

  client_max_body_size 4G;
  keepalive_timeout 10;

  error_page 500 502 504 /500.html;
  error_page 503 @503;

  location @puma_appname_production {
    proxy_http_version 1.1;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;
    proxy_redirect off;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
      proxy_set_header X-Forwarded-Proto http;
      proxy_pass http://puma_appname_production;
    # limit_req zone=one;
    access_log /var/www/appname/shared/log/nginx.access.log;
    error_log /var/www/appname/shared/log/nginx.error.log;
  }

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

  location = /50x.html {
    root html;
  }

  location = /404.html {
    root html;
  }

  location @503 {
    error_page 405 = /system/maintenance.html;
    if (-f $document_root/system/maintenance.html) {
      rewrite ^(.*)$ /system/maintenance.html break;
    }
    rewrite ^(.*)$ /503.html break;
  }

  if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)$ ){
    return 405;
  }

  if (-f $document_root/system/maintenance.html) {
    return 503;
  }
}

我每次都需要恢复部署以便它可以正常工作。我不知道会发生什么

rails / nginx / capistrano3 / puma：（111：连接被拒绝），同时连接到上游
