在Hostinger安装VPS，使用Ubuntu 24.04 LTS和CloudPanel的LEMP堆栈

安装
1

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：

server {
    listen 80;
    listen [::]:80;
    server_name forum.linguagemclipper.com.br;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    http2 on;
    http3 off;
    server_name forum.linguagemclipper.com.br;

    ssl_certificate     /etc/letsencrypt/live/forum.linguagemclipper.com.br/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/forum.linguagemclipper.com.br/privkey.pem;

    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header Host $host;
        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：

templates:
  - "templates/postgres.template.yml"
  - "templates/redis.template.yml"
  - "templates/web.template.yml"
  ## Uncomment the next line to enable the IPv6 listener
  #- "templates/web.ipv6.template.yml"
  - "templates/web.ratelimited.template.yml"
  ## Uncomment these two lines if you wish to add Lets Encrypt (https)
#  - "templates/web.ssl.template.yml"
#  - "templates/web.letsencrypt.ssl.template.yml"

## which TCP/IP ports should this container expose?
## If you want Discourse to share a port with another webserver like Apache or nginx,
## see https://meta.discourse.org/t/17247 for details
expose:
- "8080:80"   # http internal Discourse mapped to port 8080
#  - "3000:80"   # http
#  - "4433:443"  # https

params:
  db_default_text_search_config: "pg_catalog.english"

  ## Set db_shared_buffers to a max of 25% of the total memory.
  ## will be set automatically by bootstrap based on detected RAM, or you can override
  db_shared_buffers: "2048MB"

  ## can improve sorting performance, but adds memory usage per-connection
  db_work_mem: "40MB"

  ## Which Git revision should this container use? (default: tests-passed)
  #version: tests-passed

env:
  LC_ALL: en_US.UTF-8
  LANG: en_US.UTF-8
  LANGUAGE: en_US.UTF-8
  DISCOURSE_DEFAULT_LOCALE: pt_BR

  # HTTPS is forced, even without using internal SSL
  DISCOURSE_FORCE_HTTPS: true

  ## How many concurrent web requests are supported? Depends on memory and CPU cores.
  ## will be set automatically by bootstrap based on detected CPUs, or you can override
  UNICORN_WORKERS: 4

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。
