大蓝色按钮安装错误:“域挑战失败”,然后是“500 内部服务器错误 - nginx”

语境:

  • 我想通过 SSH 在 Ubuntu 虚拟机上安装 Big Blue Button;
  • 我正确地遵循了官方教程“安装”部分;
  • 我在终端上输入以下命令:wget -qO- https://raw.githubusercontent.com/bigbluebutton/bbb-install/v2.7.x-release/bbb-install.sh | bash -s -- -w -v focal-270 -s <here the domain name> -e <here the email> -g -k使用“此处域名”和“此处电子邮件”的真实数据;
  • 我有安装错误详细如下;
  • 通过HTTP访问真正的“这里的域名”给我“500内部服务器错误——nginx”;
  • 无法通过 HTTPS 访问:“ERR_CONNECTION_REFUSED”。

安装错误尽显其荣耀:

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: <here the domain name>
   Type:   caa
   Detail: CAA record for <HERE THE MAIN DOMAIN NAME> prevents issuance
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.

让我们加密日志尽显其荣耀:

问题:

  1. 由于问题似乎是在安装过程中从 SSL 证书开始的,禁用/删除它可以解决“500 内部服务器错误”吗?
  2. 如果是,如何在不卸载并重新安装 Big Blue Button 的情况下做到这一点? (我认为卸载和重新安装会更加痛苦,因为留下残留物会产生全新的错误)
  3. 如果没有,如何排查“500 Internal Server Error”,找到其原因和解决方案?

答案1

失去与服务器的连接的问题非常简单:

  1. 官方教程告诉启用防火墙 (ufw) 仅允许 HTTP(端口 80)和 HTTPS(端口 443)流量;
  2. 如果我使用 SSH,我也应该启用端口 22。更改此设置使我可以再次连接。

现在,关于我通过 HTTP 收到的“500 内部服务器错误”,官方故障排除页面告诉 GreenLight 出了问题,因此重新安装没有 GreenLight 的 Big Blue Button 可以“解决”它。
