升级到3.4后无法连接到Web服务器

[tomtjes (Thomas Reintjes)]

我刚使用 ./launcher rebuild app 更新了，现在无法访问网站。Postgres 升级或重建过程中没有出现任何错误。这是 discourse doctor 的输出。

有什么可能的原因吗？

[david (David Taylor)]

在过去大约两个小时内，您尝试过重建吗？我们之前遇到过一个问题，但现在已经解决了

Site offline after rebuild (4th Feb 2025)

Sorry for the disruption everyone! The fix is now live, so running another ./launcher rebuild app should bring things back online. Please let us know if you’re still seeing any issues after that.

[tomtjes (Thomas Reintjes)]

是的，过去一小时内已重建两次

[david (David Taylor)]

@tomtjes

现在网站无法访问

您在访问网站时看到什么错误？

[tomtjes (Thomas Reintjes)]

“Safari 无法连接到服务器”

[david (David Taylor)]

在您的服务器上，请尝试运行

cd /var/discourse
git rev-parse HEAD

它应该显示

# git rev-parse HEAD
efd6bc8ccbd9057c04d909ff48ecf8b704cae3ff

[tomtjes (Thomas Reintjes)]

是的，它做到了

[david (David Taylor)]

您的安装有什么“不寻常”之处吗？您在标准安装的基础上有所偏离吗？

您描述的问题听起来与我链接的主题中的问题非常相似。但如果您看到的是 discourse_docker 版本的 efd6bc8...，那么您应该已经修复了

[tomtjes (Thomas Reintjes)]

我想不到还有什么了，除非我从 fstab 中的磁盘挂载了 /var/discourse。但它已经这样运行很多年了。

好吧，谢谢你的帮助。如果还有其他想法，请告诉我。

[david (David Taylor)]

为了检查同样的问题是否影响到您，您可以这样做：

./launcher enter app
cat /etc/nginx/conf.d/discourse.conf

该文件中的某个位置应该有：

listen 443 ssl;

如果缺少这一行，那么症状就与其他主题相同。

如果存在……那么恐怕我们需要找出完全不同的问题了

[tomtjes (Thomas Reintjes)]

是的，那里有

[tomtjes (Thomas Reintjes)]

我又看了一下，在又一次重建后立即运行了 docker logs app。有人能帮我弄明白这是怎么回事吗？

这似乎是由以下原因引起的：

Setup Let’s Encrypt + non-www > www

I finally made it work, and thought to put everything together in case someone needs it. This info is assembled from different topics on this forum. Thanks to @brahn and @techAPJ. This assumes you’ve completed the initial Let’s Encrypt setup: After you’ve done it, the following needs to be added to the app.yml in hooks section. It will do two things: setup SSL for both example.com and www.example.com. Just replace example.com with your domain name. redirect example.com to www.example.com I…
