Discourse因证书过期而失败，重建应用程序后Discourse无法工作

支持 安装
1

我在 Ubuntu Server 22.04 上运行 Discourse。由于未知原因，我的 Discourse 证书神秘地过期了。我使用默认的 Docker 安装方法，并以所有默认设置安装了 Discourse。证书过期后，我尝试通过 ./launcher rebuild app 重建 Discourse 以续期证书。现在，当我尝试在 Safari 中打开我的 Discourse 网站时，Safari 显示以下错误：Safari 无法打开页面“www.randamckeownkrebsbach.com”，因为托管该页面的服务器没有响应。Ubuntu 上的 Docker 似乎运行正常。我不确定从哪里开始调试以及如何修复此问题，需要一些帮助。以下是 Discourse 重建后的一些日志：

./launcher enter app

我的 Nginx 日志是空的。

能否请有人帮我调试一下，让我的 Discourse 服务器重新运行起来？看起来我可能需要对 Redis 做些什么，但我不知道具体该怎么做。

2

你好 Dan :slight_smile:

运行 ./launcher rebuild app 时屏幕上显示了什么？输出中有任何可以帮助缩小范围的错误吗？

如果你还没试过，运行 ./discourse-doctor 也有帮助吗？

3

我不记得在重新构建应用程序时出现任何错误。但如果这对您有帮助，我可以再次重新构建它。我目前正在运行 discourse-doctor，完成后会发布结果。

在您的实际 app.yml 文件中，主机名值是什么？

7

www.randamckeownkrebsbach.com
我刚刚手动输入了 www.example.com 以避免直接显示我的网站。但它实际上显示了网站的正确名称，即 www.randamckeownkrebsbach.com

8

@JammyDodger 我已提供您问题的答案。您是否还有可能帮助我弄清楚这个问题？

  ## TODO: 此 Discourse 实例将响应的域名
  ## 必需。Discourse 不能使用纯 IP 地址。
  DISCOURSE_HOSTNAME: www.randamckeownkrebsbach.com

  ## 如果您希望容器使用与上面指定的相同主机名（默认“$hostname-$config”）启动（-h 选项），请取消注释
  #DOCKER_USE_HOSTNAME: true

○ → 主机 www.randamckeownkrebsbach.com
www.randamckeownkrebsbach.com 是 randamckeownkrebsbach.com 的别名。
randamckeownkrebsbach.com 的地址是 129.80.235.254

这是服务器的正确 IP 吗？它似乎没有在 22、80 或 443 端口上监听。

11

是的，那是服务器的 IP 地址。您是如何弄清楚它正在监听哪些端口的，以及我该如何解决这个问题？端口 22 仅可从我的 IP 地址访问，这就是为什么从端口扫描来看它看起来是关闭的。我的 Ubuntu 服务器防火墙已打开，并且我的 discourse 应用程序正在运行。我需要调整 Docker 映像中的什么才能让服务器监听 80、443 端口？

12

如果您使用的是标准安装，那么 80 和 443 将按标准进行监听。请检查您的 app.yml 中的 expose: 部分。

13

您的防火墙是否阻止了端口 80 或 443？

如果证书过期，很可能是因为 Let’s Encrypt 无法访问您的服务器。然后您很可能会达到速率限制。

14

我的防火墙对那些端口是完全开放的。我不明白你说的关于证书过期、Let’s Encrypt 和速率限制是什么意思。

15

这些从您的服务器上做什么？

curl localhost
curl http://www.randamckeownkrebsbach.com/
curl https://www.randamckeownkrebsbach.com/

到 https://www.randamckeownkrebsbach.com/ 的连接超时，所以要么是解析到错误的地址，要么是您的防火墙在干扰。

17

这表明 Discourse 正在您登录的服务器上运行。

而 www.randamckeownkrebsbach.com 要么没有指向该服务器，要么存在防火墙或网络问题，阻止了到那里的连接。

您可能需要在 Oracle 的其他地方打开端口。这很可能是一个网络问题，而不是本地防火墙问题。Permitting Public TCP Traffic to Oracle Compute Cloud Service Instances 可能会有帮助。

18

我已经解决了这个问题。你说得对。在我的 Oracle 实例的防火墙中，对于 http，我在目标和源上都设置了端口 80。https 也是如此。我所做的就是将 http 和 https 防火墙中的源端口都更改为“any”，并将目标端口设置为 80,443。老实说，我甚至不记得在网站停止工作之前更改过防火墙设置，但我很高兴你能帮助我调试和诊断问题！非常感谢你的帮助！
