我在 AWS 上遇到了 HAProxy 配置问题。
问题是当我通过 SSL 发出请求时，它会触发两种类型的错误：
- 当我访问 https 时，出现以下错误：“纯 HTTP 请求已发送到 HTTPS 端口”
- 当我执行这样的 cli 命令时，
openssl s_client -connect 127.0.0.1:443我收到以下响应：

现在我完全不知道该怎么做了。我该如何解决这个问题？
答案1
对于 #1，如果您的 normal_nginx 后端服务器正在运行 https，HAProxy 将无法正确连接；如果不进行强制，它无法理解 https 后端。您可以使用 stunnel 说服它发出 SSL 请求。
对于 #2，您必须向 openssl 传递 cafile 或 capath，以便它验证服务器的证书。错误的其余部分并不令人担忧——它实际上是说您没有足够快地询问您想要什么，因此它断开了您的连接。
