nginx：[emerg] 未知的“name”变量，nginx：[emerg] 未知的“ssl_preread_server_name”变量

nginx：[emerg] 未知的“name”变量，nginx：[emerg] 未知的“ssl_preread_server_name”变量

我正在尝试使用 Debian 11 中的 NGINX 1.18 设置自己的 Stealth VPN 服务器。我遵循本指南但许多指令不起作用。问题是当我发出nginx -t测试命令时输出是：

 - nginx: [emerg] unknown "ssl_preread_server_name" variable

我将此变量从 更改$ssl_preread_server_name为$server_name如果问题仅出在这个特定变量上，并查看是否还有其他错误，则测试通过，但发现另一个变量错误，即这个：

 - nginx: [emerg] unknown "name" variable`

这是文件 os 中我最后一个服务器代码块nginx.conf，我不希望它再发现任何错误。我检查了 Nginx 变量的原始数据集，变量$name和$ssl_preread_server_name是官方的并且存在。我遵循的指南说它们应该像这样分配，但互联网上没有其他指南，所以我有点卡住了。

到目前为止，我只对这两个变量有问题。它们位于map块和最后server一个块中。非常感谢您的帮助

问题是您的 nginx 没有所需的ngx_stream_ssl_preread模块。您需要找到包含此模块的 nginx 版本。
