Rails - Elastic Beanstalk nginx/error.log

Question

尝试将我的 rails 应用程序上传到弹性 beantalk。我已经成功部署了我的应用程序并创建了 postgres 数据库。我的应用程序在开发服务器上的 sqlite3 上运行。

我的 eb 状态已就绪，运行状况为绿色。

我的 eb 日志文件；

我对eb还很陌生，所以我想知道问题是否因为以下原因而出现；

1. 我没有安装节点，所以无法连接
2. 或者我的安全组有问题。如图所示，我总共有 4 个。

我的网络接口； 当我尝试分离 RDS 安全组时，即使我以 root 身份登录，它也会给出错误无授权。
我已经尝试解决这个问题几个小时了，非常感谢任何帮助！

编辑 我想我和here 有同样的问题。但是不知道怎么解决

Answer 1

你的问题从 Nginx 日志中很清楚：

connect() 到 unix:///var/run/puma/my_app.sock 在连接上游时失败（2：没有这样的文件或目录）

上面写着：

没有这样的文件或目录

这意味着您的套接字在此路径中不存在：

/var/run/puma/my_app.sock

1. 您需要将路径设置为与 Rails/Puma 中的相同 上游（即配置）

2. 什么时候你会这样做不要忘记以确保 Nginx 用户 可以访问需要 RW 访问权限的套接字。
