“PGError：没有连接到服务器”闲置后

发布于 2024-10-11 14:20:24 字数 10478 浏览 2 评论 0原文

在我的应用程序闲置一夜后，当我早上尝试访问它时，我收到 500 内部服务器错误，并且日志显示“PGError：没有与服务器的连接”。在第一个请求之后，如果我再次刷新页面，一切都很好。

我在远程服务器上运行 Ubuntu 10.04 和 apache 2、Passenger 3.0.2、Rails 2.3.8 和 Postgres 8.4。

有什么想法如何解决这个问题吗？

这是日志：

After my application sits idle overnight, when I try to access it in the morning I get a 500 Internal server error and the logs indicate "PGError: no connection to the server". After this first request if I refresh the page again everything is fine.

I'm running Ubuntu 10.04 with apache 2, Passenger 3.0.2, Rails 2.3.8, and Postgres 8.4 on a remote server.

Any ideas how to fix this?

Here is the log:

在研究这个问题的我自己的版本时遇到了这个问题。看起来好像您正在生成库中使用 fork 方法（可能是 Phusion Passenger 的一部分？），目前该方法似乎与 Postgres 不兼容。

我希望这为您和/或下一位访客提供可能的线索。

Came across this whilst researching my own version of this problem. It looks as if you are using the fork method in the spawn library (perhaps part of Phusion Passenger?), which does not appear to be Postgres compatible at this moment.

I hope this provides a possible clue for you and/or the next visitor.

尝试通过将此行添加到您的database.yml文件来关闭SSL数据库连接：

sslmode: disable

Try turning off SSL database connections by adding this line to your database.yml file:

sslmode: disable
