我正在运行 3 个使用 PHP Generic 和 Varnish 的 Drupal 7 网站。LEMP 堆栈使用 NGINX。
我想为我的一个网站安装 Discourse 作为论坛。
我安装了 docker，discourse，配置了子域和 /etc/nginx/sites-enabled/forum.linguagemclipper.com.br.conf。
我创建了证书。
安装后，我收到：The provided host name is not valid for this server.
我收到了几个关于使用相同端口的错误。
我认为我需要修复我的 .conf 和我的 app.yml，我已经尝试了多次，并得到了 chatgpt 的帮助，我运行了 ./discourse-doctor。
我不知道该怎么办了……
我的 .conf：
```plaintext
server {
listen 80;
listen [::]:80;
server_name forum.linguagemclipper.com.br;
return 301 https://$host$request_uri;
}
server {
listen 443 ssl;

http2 on;
http3 off;

proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https;
}
}
```
我的 app.yml：
```plaintext

- "templates/postgres.template.yml"

## Uncomment the next line to enable the IPv6 listener

看起来有其他东西在使用该端口。尝试换一个端口？在更改 `app.yml` 中的端口后，您可以执行
```
./launcher destroy app;./launcher start app
```
而不是进行完全重建。

DISCOURSE已安装但无法发送电子邮件
我已将app.yml中的Discourse端口更改为8888，并在Cloudpanel的vhost中也进行了更改，然后停止了NGINX以重新编译Discourse，并且成功了。
我重新启用了NGINX，网站和Discourse都正常运行。
问题是Discourse根本无法发送电子邮件，我们需要帐户激活电子邮件。
我已经更改了端口，但没有效果。
在同一台服务器上，我在Docker中安装了Mailcow，并且电子邮件的发送和接收都正常。

看起来你在你的服务器上做一些很有创意的酷炫工作！请注意，我们只能在你使用官方安装说明的情况下提供支持。请查看并再次尝试遵循说明，其中也提供了故障排除步骤。
